Informatec Digital » Izinsiza » Iyini i-UPS futhi kungani ikhompyutha yakho iyidinga?

Uma ikhaya lakho noma ihhovisi lakho libhekana nokuphazamiseka kukagesi njalo noma ukushintshashintsha kwamandla kagesi , ngokushesha noma kamuva uzoba sengozini yokulahlekelwa idatha yakho, umsebenzi wakho... ngisho nesikhathi sokuphila kwekhompyutha yakho. Ukunqamuka kwamandla kagesi ngesikhathi esibi kakhulu kungonakalisa amafayela, kulimaze i-hard drive yakho, noma kuphahlaze iseva ngesikhathi lapho uyidinga kakhulu, njengoba sichaza esihlokweni sethu ngamaphutha afinyeza isikhathi sokuphila kwe-PC yakho.

Yilapho i -UPS, i-Uninterruptible Power Supply edumile , ingena khona . Yileyo divayisi cishe engekho onaka kuyo, kodwa lapho ugesi uphela, iba yiqhawe elithule elikunikeza imizuzu embalwa yamandla okusekelayo, liqinise ugesi, futhi livimbele ukulungiswa okubizayo. Ake sibheke ngokuningiliziwe ukuthi iyini, isebenza kanjani, izinhlobo ezahlukene ezitholakalayo, nokuthi ungayikhetha kanjani efanele i-PC yakho noma ibhizinisi lakho.

Iyini i-UPS futhi kungani ikhompyutha yakho iyidinga?

Isifinyezo se-UPS simelela i- Uninterruptible Power Supply. Yidivayisi kagesi ebekwe phakathi kokunikezwa kwamandla amakhulu namadivayisi akho (amakhompyutha, amaseva, ama-router, ama-electronics enethiwekhi, imishini yezokwelapha, njll.) enikeza amandla okusekela ngamabhethri lapho amandla amakhulu ehluleka noma kunezinkinga ezinkulu ngegridi.

Ngaphansi kwezimo ezijwayelekile, i-UPS ivumela noma ilinganisele amandla e-mains, kodwa ngokushesha nje lapho ibona ukucima kombane, ukwehla kwamandla kagesi, noma ukuphakama okuyingozi, ishintshela ngokuzenzakalelayo ebhethrini layo langaphakathi ngama-millisecond. Ngale ndlela, i-PC yakho ayivali ngokuzumayo, ikunike isikhathi sokulondoloza umsebenzi wakho futhi uyivale kahle.

Ngaphezu kokuphila kwebhethri okweluliwe, amamodeli amaningi afaka i- AVR (Automatic Voltage Regulator) , eshelela ukuguquguquka kwamandla kagesi, ihlunge ama-spikes, umsindo, kanye nokungalungi okuvela kugridi kagesi. Lokhu kunciphisa ukucindezeleka ekuhlinzekweni kwamandla ekhompyutha, kwehlisa izinga lokushisa lokusebenza, futhi kwandise isikhathi sayo sokuphila.

Izingxenye eziyisisekelo kanye nokusebenza kwe-UPS

Ngaphakathi, i-UPS akuyona nje "ibhokisi elinamabhethri." Ihlanganisa amamojula amaningana kagesi ahambisanayo ukukunikeza ugesi ozinzile nongaphazanyiswa, noma ngabe igridi yehla noma iziphatha ngendlela engafanele.

Ingxenye yokuqala eyisihluthulelo ibhethri , okuyidivayisi yokugcina amandla. Ingakhiwa yiseli elilodwa noma ngaphezulu le-lead-acid noma i-lithium, kuye ngemodeli kanye nobubanzi. Uma ugesi we-mains usebenza kahle, i-UPS igcina amabhethri eshajwe; uma ugesi we-mains uphela, iwasebenzisela ukugcina imishini yakho isebenza isikhathi esilinganiselwe.

Ingxenye yesibili yi- rectifier , eguqula i-alternating current (AC) kusuka kuma-mains ibe yi-direct current (DC). Le DC current isetshenziselwa ukushaja amabhethri kanye nokunika amandla i-inverter. Ezinhlelweni ze-UPS ezithuthuke kakhulu (ukuguqulwa kabili ku-inthanethi), i-rectifier ihlala isebenza.

Ingxenye yesithathu yi- inverter , eyenza inqubo ephambene: iguqula ugesi oqondile ovela kumabhethri noma ku-rectifier ubuyele kugesi oshintshashintshayo wekhwalithi ephezulu, nge-voltage kanye nemvamisa efanele yokunika amandla imishini yakho. Kumamodeli amaningi aphakathi nendawo kanye naphezulu, i-inverter iyakwazi ukukhiqiza igagasi elihlanzekile le-sine, elifanelekela izinsiza zikagesi ezine-PFC esebenzayo , ama-motor, ama-boiler, noma ama-electronics azwelayo.

Okokugcina, izinhlelo eziningi ze-UPS zifaka i -static switch noma i-bypass relay . Le ngxenye ivumela ama-main ukuthi anikeze amandla ngqo umthwalo uma i-UPS ihlangabezana nokwehluleka kwangaphakathi noma idinga ukudlula ama-main, idlula ama-electronics e-UPS. Isebenza njengohlobo "lomugqa wokugcina wokuzivikela" ukuvimbela imishini yakho ukuthi ingalahlekelwa amandla uma i-UPS ingasebenzi kahle.

I-UPS vs I-Voltage Regulator (AVR): Umehluko Obalulekile

Kuvamile ukudida i-UPS nesilawuli sikagesi esizimele noma i-AVR , ngoba zombili zihlobene nokuvikelwa kukagesi. Kodwa-ke, azifani futhi azifezi injongo efanayo, yize zihambisana kahle kakhulu.

I-AVR ezimele iyidivayisi ezinzisa amandla kagesi kuphela : ilungisa ukukhuphuka nokwehla, ihlunga ama-spikes, inciphise ukuphambuka, futhi igcina amandla okukhipha asondele ku-230V ngangokunokwenzeka. Kodwa-ke, ayinawo amabhethri, ngakho uma ugesi ucima, imishini yakho izoqhubeka ivaliwe.

Ngakolunye uhlangothi, i-UPS ifaka amabhethri kanye ne-elekthronikhi yokusekelayo . Ngaphezu kokulawula amandla (uma ine-AVR), ingagcina amadivayisi akho esebenza isikhathi esithile lapho amandla amakhulu ehluleka. Ngakho-ke, ivikela ekunqamukeni kwamandla kagesi, ukucima okuncane, ukwehla kwamandla kagesi, kanye nokucima kwamandla kagesi, hhayi nje ukushintshashintsha kwamandla kagesi.

Ngokuphathelene nokuphepha, i-UPS iyisinqumo esifanele uma ungakwazi ukukhokhela ukucima kukagesi okungazelelwe (izikhungo zedatha, ukunakekelwa kwezempilo, amaseva, izinhlelo zokuqapha ividiyo, izindawo zokusebenza). I-AVR isetshenziswa kakhulu ekuvikeleni ikhwalithi kagesi ezindaweni lapho ukucima kukagesi kwamukeleka khona, kodwa ufuna ukuvimbela umonakalo ovela ekukhuphukeni okuphindaphindiwe.

Ngokuphathelene nentengo nokugcinwa, i-UPS ibiza kakhulu ngoba amabhethri ayindleko enkulu futhi adinga ukushintshwa njalo. I-AVR emsulwa iyonga kakhulu, idinga ukulungiswa okuncane, futhi ngokuvamile ihlala isikhathi eside. Ngakho-ke, izixazululo eziningi eziphakathi nendawo zihlanganisa i-UPS esebenzisana (evele ine-AVR ehlanganisiwe) ukuze ibe nezici zombili kuyunithi eyodwa.

Isetshenziselwani ngempela i-UPS?

Umsebenzi oyinhloko we-UPS ukuvimbela imishini yakho ukuthi ingavali kungazelelwe , ngaleyo ndlela igweme ukulahleka kwedatha noma ukulimala kwehadiwe ngenxa yokuphela kukagesi. Kodwa izinzuzo zayo zidlulela ngale kwaleyo "mizuzu eyengeziwe" ukuze kulondolozwe umsebenzi wakho.

Ngakolunye uhlangothi, isebenza njengesivikelo ekukhuphukeni kwamandla kagesi, ukucwila, kanye nokushintshashintsha . Igridi kagesi, ikakhulukazi ezindaweni ezithile noma ezakhiweni ezindala, ingaletha ama-harmonics, umsindo, kanye nezinguquko ezisheshayo ezonakalisa izinsiza zamandla, zishise kakhulu izingxenye, futhi zinciphise isikhathi sokuphila kwehadiwe.

Ngakolunye uhlangothi, ezindaweni ezibucayi njengezikhungo zedatha, izibhedlela, izikhungo zezimboni, noma izikhungo zokuxhumana , i-UPS iyingxenye ebalulekile yengqalasizinda. Ivumela iseva, uhlelo lokuxhumana, noma imishini yezokwelapha ukuthi ibe namandla angaguquki ngenkathi ijenereyitha kadizili iqala noma uhlelo lushintshela kokunye ukufakwa okungadingeki.

Ngisho nasekhaya, i-UPS enobukhulu obufanele ingavikela amakhompyutha, ama-game consoles, ama-router, amakhamera e-IP, amadivayisi e-NAS, noma amaseva amancane asekhaya . Kumsebenzisi osebenza kude, ukuphuthelwa ucingo lwevidiyo olubalulekile noma ukonakalisa isizindalwazi sendawo ngenxa yokuphela kukagesi kungabiza kakhulu kunezindleko ze-UPS.

Ngokwendlela engokoqobo, i-UPS iqinisekisa ukuthi uma kwenzeka inkinga kagesi, impilo yakho yansuku zonke ayibhidliki : uhlala usebenza imizuzu embalwa, uvikele amadivayisi akho, futhi ugweme ukukhuphuka kukagesi okungakushiya ungenamishini.

Izinhlobo ze-UPS: yiziphi ubuchwepheshe ezikhona nokuthi kufanele zisetshenziswe nini ngayinye

Akuzona zonke izinhlelo ze-UPS ezinikeza izinga elifanayo lokuvikela noma ezenzelwe injongo efanayo. Ubuchwepheshe bangaphakathi bunquma izinga lokuvikela , isikhathi sokushintsha, ikhwalithi yamandla, kanye nentengo. Ngokubanzi, kunezinhlobo ezintathu eziyinhloko zokusetshenziswa kwekhompyutha.

I-UPS engaxhunyiwe ku-inthanethi noma eyisipele (engaxhunyiwe ku-inthanethi)

I-UPS engaxhunyiwe ku-inthanethi iyindlela elula nengabizi kakhulu yokuklama. Ngenkathi amandla amakhulu evuliwe, isebenza ngemodi "yokudlula" : amandla adlula cishe ngqo kumadivayisi, ngaphandle kokuhlunga okuthuthukisiwe, kanti i-UPS ishaja amabhethri ayo kuphela futhi iqapha isimo somugqa.

Uma ithola ukucima kukagesi, ukucima ngokuphelele, noma ukwehla okukhulu kwamandla, ishintshela kumandla ebhethri ngaphakathi kwama-millisecond (ngokuvamile phakathi kwama-2 nama-10 ms). Kusukela ngaleso sikhathi, i-inverter yangaphakathi inika amandla amadivayisi akho kuze kube yilapho ibhethri seliphelile noma igridi ibuyiselwa.

Lolu hlobo lwe-UPS ngokuvamile alufaki i-AVR ehlanganisiwe , ngakho-ke aluhlungi ukushintshashintsha kwamandla kagesi "okuncane". Ngakho-ke, kunconywa ezindaweni ezinegridi yamandla ezinzile kanye nokuphazamiseka okumbalwa: inikeza amandla okusekelayo ngesikhathi sokungasebenzi, kodwa ayithuthukisi kakhulu ikhwalithi yamandla.

Zifanele ama-PC asezingeni lokuqala, amathelevishini, ama-monitor, ama-router, namakhompyutha amancane asekhaya ezindaweni lapho ikhwalithi yenethiwekhi yamukeleka khona. Azifaneleki kumadivayisi azwela kakhulu noma amanethiwekhi kagesi "angcolile" ikakhulukazi.

I-Interactive noma i-In-line UPS (I-Line-Interactive)

I-UPS esebenzisana nemigqa ilungele kakhulu abasebenzisi abaningi kanye namabhizinisi amancane. Ukusebenza kwayo kufana ne-UPS engaxhunyiwe ku-inthanethi , kodwa ifaka ama-elekthronikhi engeziwe ukulawula i-voltage ngaphambi kokuba ifike emishinini yakho.

Isihluthulelo ukuthi ihlanganisa i -AVR elungisa ngokuzenzakalelayo ukuguquguquka okucishe kube ngu-±15% . Uma kwenzeka ukwenyuka noma ukuwa okuphakathi, ilungisa i-transformer (umphumela we-buck/boost) ngaphandle kokudonsa amandla ebhethri, inciphise ukuguguleka kwebhethri futhi ilethe i-voltage eqinile.

Uma kukhona ukucima kukagesi noma inkinga enkulu, i-interactive UPS ishintshela nakumandla ebhethri ngemizuzwana embalwa . Lokhu kuphazamiseka okufushane kuvame ukubekezelelwa amakhompyutha amaningi kanye nemishini kagesi, kodwa kungaba yinto ebalulekile kumadivayisi azwela kakhulu.

Phakathi kwamamodeli asebenzisanayo, sithola lawo akhiqiza i-waveform "pseudo-sinusoidal" (eyanele amakhompyutha nemishini eminingi yehhovisi) kanye namanye ane -waveform emsulwa ye-sinusoidal , enconyelwa izinsiza zikagesi ezine-PFC esebenzayo, ama-boiler, amaphampu, ama-motor, njll. Lawa avame ukuzola futhi afanele izindawo zokusebenza ezidinga amandla amaningi.

Ziyisinqumo esihle kakhulu sama -PC asezingeni eliphakathi naphezulu, ama-console, amaseva amancane, imishini yenethiwekhi, amakhamera okuphepha, kanye nokusetshenziswa kwehhovisi . Ngokuvamile, ziyizinhlelo ze-UPS ezinconywayo zamadivayisi amaningi ekhompyutha esimanje.

UPS ku-inthanethi noma ukuguqulwa kabili (ku-inthanethi)

I-UPS eku-inthanethi iyisistimu yokuvikela ephezulu kakhulu. Esikhundleni sokuvumela ugesi ukuthi udlule futhi usebenze kuphela uma kunezinkinga, isebenza kwimodi yokuguqulwa kabili ngokuqhubekayo : iguqula njalo amandla e-AC amakhulu abe yi-DC bese ibuyela ku-AC yemishini yakho.

Lokhu kusho ukuthi umthwalo uhlala uhlukaniswe nogesi osuka ku-mains . Noma yikuphi ukujiya, umsindo, ukuphambuka, ukusika okuncane, noma ukucwila kumuncwa uhlelo, oluhlala lunikeza igagasi le-sine elihlanzekile, elizinzile elingenazo izikhathi zokushintsha ezibonakala (ukushintshela kumandla ebhethri kwenzeka ngokushesha).

Ngenxa yomklamo wayo, uhlobo olulodwa lwe-UPS olukwazi ukuqinisekisa ukuvikelwa okuphelele kuma-voltage angaphezu nangaphansi, ama-harmonics kanye nama-micro-cuts , futhi lufaneleka kakhulu uma imishini kungamelwe ishiywe ingenawo amandla noma imelane noshintsho olukhulu lwenethiwekhi.

Zisetshenziswa kakhulu kumaseva abalulekile, amaqoqo, izikhungo zedatha, imishini yezokwelapha, amanethiwekhi amakhulu okuxhumana , kanye nezikhungo zezimboni ezibiza kakhulu. Zibiza kakhulu futhi amabhethri azo adlula imijikelezo eminingi, okwenza ukulungiswa kube nzima kakhulu.

Eminye imiklamo yobungcweti kanye nokuhlukahluka

Esimweni sezimboni kanye nesikhungo sedatha, kuye kwasungulwa izinhlobo ezifana ne -resonant industrial UPS, i-delta conversion UPS, noma imiklamo ye-hybrid ehlanganisa izici ze-topology ezahlukahlukene ukuze kulinganiswe ukusebenza kahle kanye nokuvikelwa.

Lezi zinhlelo zingaphatha kangcono i-input power factor, zinciphise ukusetshenziswa kwamandla kwe-UPS , futhi zivumelane nemithwalo enzima kakhulu noma leyo enamaphrofayili okusetshenziswa ayinkimbinkimbi. Zivamile ezikhungweni ezinkulu zedatha, ezindaweni zocwaningo, kanye nasezingqalasizinda ezinkulu.

Uhlobo luni lwe-UPS okufanele ulukhethe kuye ngesimo sakho

Ukukhetha uhlobo olufanele lwe-UPS kubaluleke kakhulu njengokucabanga ngokukhipha amandla. Ekugcineni, kumayelana nokufanisa izinga lokuvikela nenani lalokho ofuna ukukuvikela kanye nekhwalithi yokunikezwa kwamandla akho.

I-UPS engaxhunyiwe ku-inthanethi iyindlela enhle yezindawo ezinenethiwekhi eqinile nemishini engazweli kakhulu . Isibonelo, i-PC yedeskithophu eyisisekelo, i-TV, i-router, kanye ne-monitor eyodwa noma ezimbili endlini lapho ugesi ungasebenzi khona njalo futhi i-voltage ingavamile ukushintshashintsha kakhulu.

I-UPS esebenzisanayo iyindlela yokusebenza enconywayo ezimweni eziningi. Ivikela kokubili ekunqamukeni kukagesi kanye nokushintshashintsha kwamandla kagesi ngaphandle kokusebenzisa imali eningi, futhi ifaneleka kahle kumakhompyutha omuntu siqu, ama-game consoles, amadivayisi e-NAS, amaseva amancane, amakhamera, izinhlelo ze-POS, kanye namahhovisi aphelele.

Kufanele ucabangele i-UPS eku-inthanethi uma ubhekene nengqalasizinda ebalulekile noma ebiza kakhulu : amaseva angenakuvalwa, izinhlelo zezimboni, izikhungo zedatha, amanethiwekhi edatha yebhizinisi, kanye, ngokuvamile, noma yikuphi ukufakwa lapho ukwehluleka kukagesi kuholela ekulahlekelweni okukhulu noma ezinkingeni zokuphepha.

Ngaphambi kokunquma, kufanelekile futhi ukucabangela ukuthi indawo izokhula yini: uma uhlela ukwengeza imishini eyengeziwe esikhathini esizayo, kungaba kuhle ukukhetha i-UPS enamandla aphezulu kancane ukuze ungaphelelwa ugesi ngemva kwezinyanga ezimbalwa.

Udinga amandla angakanani e-UPS (i-VA kanye ne-power factor)

Elinye iphuzu elibalulekile ukukala amandla ngendlela efanele. Izinhlelo ze-UPS zibonisa amandla azo ku -VA (volt-amperes) noma ku-kVA , okuyiwona mandla abonakalayo. Kodwa amadivayisi owaxhumayo avame ukucacisa ukusetshenziswa kwawo kuma-watts (W), okuyiwona mandla angempela.

Ukuze kuhlotshaniswe la manani amabili, kusetshenziswa i -power factor (PF) , inombolo ephakathi kuka-0 no-1 ekhombisa ukuthi iyiphi ingxenye yalawo mandla abonakalayo eguqulwa ibe amandla angempela awusizo. Kunethiwekhi yasekhaya noma yehhovisi, i-PF ivame ukuba phakathi kuka-0,6 no-0,7, yize izinhlelo eziningi ze-UPS zanamuhla zinikeza izici eziseduze no-0,9.

Ifomula eyisisekelo icacile: W = VA × PF . Uma ufuna ukwazi ukuthi zingaki i-VA ezidingwa yi-UPS yakho ukuze inikeze amandla umthwalo we-watt othile, mane uhlukanise amandla angempela ngesici samandla esilinganiselwe sokufakwa noma i-UPS uqobo.

Isibonelo, uma ikhompyutha yakho kanye nezinto ezisetshenziswayo ndawonye zisebenzisa cishe ama-W angu-400 futhi ulinganisela ukuthi i-power factor ingu-0,6, uzodinga i-VA engu-400 / 0,6 ≈ 667. Empeleni, kunconywa ukwengeza imajini yeziqongo zokuqala kanye nokuthuthukiswa kwesikhathi esizayo, ngakho-ke kunengqondo ukukhetha ukunikezwa kwamandla okucishe kube yi-VA engu-800-900.

Njengomthetho ojwayelekile, kuyalulekwa ukuthi ama-UPS abe nomthamo okungenani ongu-20% ngaphezu kwesamba samandla asetshenziswa yiwo wonke amadivayisi axhunyiwe. Ngamanye amazwi, engeza amandla edivayisi ngayinye bese uphindaphinda ngo-1,2 ukuze ube nomkhawulo okhululekile.

I-UPS ingagcina imishini yakho isebenza isikhathi esingakanani?

Isikhathi sokusebenza kwe-UPS sincike kakhulu emandleni amabhethri ayo kanye nomthwalo oxhunyiwe . Ukunika amandla i-PC kanye ne-monitor akufani nokunika amandla i-rack yonke yamaseva.

Umthamo webhethri uvame ukuvezwa ku -Wh (amahora e-watt) noma ku-Ah (amahora e-ampere) . Uma wazi umthamo ku-Wh kanye nokusetshenziswa kwamandla kwamadivayisi akho ku-W, ungenza isilinganiso esilula sethiyori: hlukanisa i-Wh ngo-W. Isibonelo, ibhethri engu-1000 Wh enika amandla umthwalo ongu-100 W inganikeza, ngaphansi kwezimo ezifanele, amahora angaba yi-10 okusetshenziswa.

Empeleni, izici ezifana nokushisa okuzungezile, isimo sebhethri, izinga langempela lokushaja ngesikhathi sokuphela kukagesi, kanye nokusebenza kahle kwe-inverter konke kudlala indima. Ngakho-ke, abakhiqizi abaningi banikeza amabanga ajwayelekile: phakathi kwemizuzu emi-5 neyi-15 yokusebenza ngomthwalo ofanele, owanele ukonga umsebenzi nokuvala.

Uma uxhuma amadivayisi anamandla aphansi kakhulu (ama-router, amakhamera e-IP, i-mini PC), isikhathi sokusebenza sikhula kakhulu, kanti uma ulayisha i-UPS cishe kuze kufike kumthamo wayo omkhulu, isikhathi sokusebenza sehla kakhulu. Kubalulekile ukukhumbula ukuthi akunconywa ukuthi "ucindezele" i-UPS njalo kuze kube yilapho ibhethri liphela ngokuphelele, ngoba ukukhishwa okujulile kunciphisa isikhathi sokuphila kwayo.

Ezindaweni zobungcweti njengezikhungo zedatha, kuyinto evamile ukulinganisa uhlelo ukuze lunikeze isikhathi esiphakathi komzuzu ongu-1 no-15 wesikhathi sokusekela , okuhloswe ngaso ukuvumela ukuqala abakhiqizi bedizili noma ukushintshela kwesinye isikhungo sedatha. Kulezi zindawo, ngaphezu kokugcina amahora okusebenza, isici esibalulekile ukuthi ushintsho luhlelekile futhi luphephile.

Isikhathi sokuphila kanye nokugcinwa kwe-UPS

I-UPS enakekelwe kahle ingahlala iminyaka emi-3 kuya kwemi-5 ezindaweni zasekhaya futhi kalula iminyaka eyi-10 noma ngaphezulu kumamodeli ochwepheshe, uma nje inakekelwa kahle futhi amabhethri eshintshwa uma kudingeka.

Amabhethri ngokuvamile ayisici esibaluleke kakhulu. Abakhiqizi batusa ukuwashintsha cishe njalo eminyakeni emithathu , yize lokhu kuncike kakhulu enanini lemijikelezo yokukhipha, izinga lokushisa lokusebenza, kanye nezinga lokushaja elijwayelekile. Ezinhlelweni ezinkulu noma lezo ezinamabhethri amaningi axhunywe ochungechungeni, iseli elilodwa elinephutha lingalimaza lonke ibhange lebhethri.

Ukuze wandise impilo ye-UPS yakho, kubalulekile ukuyigcina endaweni epholile, eyomile, nengenazo uthuli , futhi ugweme ugesi ongashintshi . Izinga lokushisa elifanele lingaba ngu-20-25°C; ngaphezu kwalokho, ngokwanda ngakunye okungu-10°C, impilo yebhethri ingancishiswa cishe ngesigamu.

Kubalulekile futhi ukugwema ukulayisha ngokweqile idivayisi: okungcono kakhulu, umthwalo akufanele udlule u-80% wamandla ayo ajwayelekile . Ukusebenza njalo ngomkhawulo wakho kubeka ubunzima obukhulu kuma-elekthronikhi, kuphakamisa izinga lokushisa, futhi kusheshise ukuguga kwebhethri.

Kumamodeli alula asekhaya, kungaba usizo ukulingisa ukucima kukagesi kanye ngenyanga noma njalo ezinyangeni ezimbili ngokunqamula i-UPS kuma-main bese uyivumela ukuthi isebenze ngamandla ebhethri imizuzu embalwa ngaphambi kokuyivumela ukuthi ishaje. Lokhu kusiza ukuvimbela amabhethri ukuthi ahlale esimweni sokungasebenzi njalo.

Imikhuba emihle yokunakekela nokulawula imvelo

Uma kufakwa ochwepheshe, kungcono ukuba nohlu lokuhlola lokulungisa bese uqopha konke ukuhlolwa. Lokhu kukuvumela ukuthi ubone amaphethini okwehluleka bese uthatha isinyathelo ngaphambi kokuba kuvele inkinga enkulu ngesikhathi sokuphela kukagesi.

Imisebenzi yokulungisa ejwayelekile ihlanganisa ukuhlola isimo sebhethri (i-voltage, umthamo, izinga lokushisa), ukuhlola ama-capacitor, izintambo, ukuxhumana, nama-circuit breaker , kanye nokuhlanza uthuli oluvela kumafeni nasezihlungi. Noma yiziphi izimpawu zokuvuvukala, ukugqwala, noma ukushisa okungavamile kufanele kuxazululwe ngokushesha.

Imvelo nayo ibalulekile: i-UPS kufanele ifakwe endaweni elawulwa amazinga okushisa, enomoya omuhle, futhi eyomile . Gwema ukuyibeka eduze kwamafasitela avulekile, imithombo yokushisa, noma ezindaweni ezinegesi ebolile. Ama-grille omoya akufanele nanini avinjwe ifenisha, amaphepha, noma ezinye izithiyo.

Nakuba izinhlelo eziningi ze-UPS zingamelana namazinga okushisa angaphandle kancane kwezidingo zazo, ukwenza kanjalo kuholela ekulahlekelweni kwamandla kanye nokwehluleka kwangaphambi kwesikhathi . Ukusebenza "emaphethelweni" ezidingo ngokuvamile akubizi kakhulu ngokuhamba kwesikhathi.

Isofthiwe yokuphatha nokuqapha i-UPS

Izinhlelo eziningi zesimanje ze-UPS, ikakhulukazi amamodeli asezingeni eliphakathi kanye nasezingeni eliphezulu, afaka phakathi isofthiwe yokuphatha kanye nokuqapha exhumana nemishini nge-USB, i-serial, noma inethiwekhi. Le software ingaphezu nje kwephaneli yolwazi elula.

Ngakolunye uhlangothi, ikuvumela ukuthi uhlele ukuvala okuzenzakalelayo kanye nokuqala kabusha kwesistimu yokusebenza ngesikhathi sokucima kukagesi isikhathi eside, ukuvimbela idivayisi ukuthi iphelelwe yibhethri ngokuzumayo. Lokhu kuwusizo ikakhulukazi kumaseva noma kumadivayisi e-NAS, lapho ukuvala okungcola kungonakalisa idatha.

Ngakolunye uhlangothi, inikeza idatha yesikhathi sangempela ku- voltage yokufaka neyokukhipha, imvamisa, izinga lomthwalo, iphesenti lebhethri, imicimbi, kanye nama-alamu . Izinhlelo eziningi zikuvumela ukuthi ubuke idatha yomlando, uthumele amalogi, futhi ukhiqize amagrafu ukuze uhlaziye ukuthi igridi kagesi iziphatha kanjani.

Ekufakweni okuyinkimbinkimbi, isofthiwe isetshenziselwa futhi ukuqapha izinhlelo eziningi ze-UPS ezinethiwekhi, ukuthola izaziso zokwehluleka noma amabhethri anephutha, nokuxhumanisa izenzo phakathi kwamadivayisi ahlukene. Lokhu kunikeza umphathi umbono ophelele wesimo sokuphakelwa kwamandla.

Izici ezisebenzayo okufanele uzicabangele lapho uthenga i-UPS

Ngale kobuchwepheshe namandla, kunemininingwane ewusizo kakhulu eyenza umehluko ekusetshenzisweni kwansuku zonke. Enye yazo inani lezindawo zokubeka ezinikezwa yi-UPS. Amamodeli amaningi asekhaya anezindawo zokubeka ezimbili, ezintathu, noma ezine ezivikelwe, ezanele umbhoshongo, imonitha, kanye nezinye izinto ezisetshenziswayo.

Uma ufuna ukuvikela ukufakwa okukhulu (isibonelo, ibhizinisi elincane elinemishini eminingana ), ungase ube nesithakazelo ku-rack noma i-tower UPS enamandla aphezulu bese usabalalisa ukuvikelwa ngokusebenzisa ama-power strips aqashwe noma ukufakwa okuzinikele.

Esinye isici esibalulekile impilo yebhethri oyidingayo ngempela . Uma ufuna nje ukugwema ukulahlekelwa umsebenzi wakho, imizuzu embalwa izokwanela; uma udinga ukugcina amadivayisi evuliwe isigamu sehora noma ngaphezulu, kuzodingeka ukhethe amamodeli anamabhethri anomthamo ophezulu noma ngisho nokulungiswa ngamabhange ebhethri angaphandle.

Ungakhohlwa futhi ukucabangela ukutholakala kanye nentengo yamabhethri ashintshwayo . Njengakwamanye amaphrinta, kunemishini engabizi kakhulu amabhethri ayo okuqala noma ahambisanayo abiza kakhulu. Hlola ukutholakala kanye nezindleko ngaphambi kokuthenga.

Okokugcina, khumbula ukuthi amadivayisi athile, njengamaphrinta e-laser noma imishini enezibani eziqalayo eziphezulu , akufanele axhunywe ku-UPS, njengoba lawa ma-spikes angalimaza idivayisi noma akhubeke amadivayisi ayo okuvikela. Okungcono kakhulu, i-UPS kufanele igcinelwe ama-elekthronikhi abucayi kanye nezinsiza zikagesi ezizinzile.

Ukuba ne-UPS enhle akugcini nje ngokuvimbela ukucima kukagesi okungalindelekile ngesikhathi esibi kakhulu, kodwa futhi kuvikela imishini yakho kumagridi kagesi angathembekile, kwandise isikhathi sokuphila kwehadiwe, futhi kukunikeza isikhathi sokusabela . Ukukhetha ubuchwepheshe obufanele (okungaxhunyiwe ku-inthanethi, okusebenzisanayo, noma oku-inthanethi), ukukala kahle ukukhishwa kukagesi, nokunakekela amabhethri kuguqula lelo "drowa" elincane elingaphansi kwedeski lakho libe yingxenye ebalulekile yokuphepha kwakho kwe-IT kwansuku zonke.
