Ibhethri le-UPS

Ibhethri le-UPS liwumthombo wamandla/umthombo ongaphazamiseki onikeza isipele sesikhathi esifushane noma amandla avelayo lapho amandla ephela noma ekhuphuka. Kodwa-ke, umsebenzi wayo oyinhloko ukusebenza njengesistimu yokumisa phakathi kwamandla amakhulu kanye namandla ayisipele. Lokhu kungenxa yokuthi ingasabela ngokushesha lapho amandla enyuka ngaphambi kokuthatha amandla okulondoloza ikhophi, njengoba kungathatha amaminithi ambalwa ukuphendula. Lapho isetshenziswa kakhulu ukufaka amandla emishinini yasesibhedlela kanye ne-CCTV ngesikhathi sokuhlinzwa okubucayi kanye nezimo eziphuthumayo. Noma kunjalo, kubalulekile futhi ekunikeni amandla amakhompiyutha, okokusebenza kwezokuxhumana, amabhange, nezikhungo zedatha ukuvikela ihadiwe.

Kubalulekile ukuqaphela ukuthi ibhethri le-UPS aliwona amandla ayisipele ngoba lingahlala imizuzu embalwa. Naphezu kokunikeza amandla esikhashana, ingaphinda ilungise futhi izinze izinkinga zamandla ezibangelwa ukugcwala ngokweqile noma ukuphakama kwe-voltage. Ngakho-ke, kungaba okubalulekile ukuba nesistimu yokwenza isipele ukuhlinzeka ngomthwalo oqhubekayo wokuphatha amadivayisi akho ngaphambi kokufa kwebhethri le-UPS. Unalokho engqondweni, kunezinhlobo ezintathu eziyinhloko zamabhethri e-UPS:

1. I-UPS elindile

Lolu hlobo lwebhethri le-UPS luvame ukusetshenziselwa ukuhlinzeka ngokuvikelwa kokuhlinzwa kanye nokwenza ikhophi yasenqolobaneni yamandla ngokuyixhuma ngqo kusisetshenziswa samandla angenayo. I-Standby UPS ilungele amakhaya kanye nendawo yobungcweti engadingi kakhulu njenge-PC. Uma ithola ukuphela kukagesi, ibhethri yesitoreji sangaphakathi ivula i-DC-AC inverter circuitry yayo yangaphakathi bese ixhuma kusiguquli sayo se-DC-AC. I-switchover ingase ibe khona manjalo, noma ngemva kwemizuzwana embalwa kuye ngokuthi iyunithi ye-UPS yokulinda ithatha isikhathi esingakanani ukuthola ugesi wokusetshenziswayo olahlekile.

2. I-UPS eku-inthanethi

I-UPS eku-inthanethi isebenzisa ukuguqulwa kwe-delta noma ubuchwepheshe obuphindwe kabili ngokuhlala ixhuma amabhethri kusiguquli. Ngakho-ke, ingakwazi ukugcina ukugeleza kwamanje okungaguquki phakathi nokucisha kukagesi ngenxa yokuthi ubuchwepheshe bokuguqula okukabili buzilungisa ngokuzenzakalelayo futhi bukweqe ukushintshashintsha kalula. Uma ugesi ucisha, isilungisisi siyawa esisekhethini, bese amandla azophuma ebhethrini le-UPS. I-UPS eku-inthanethi ibiza kakhulu ngenxa yekhono layo lokusebenza ngokuqhubekayo, isistimu yokupholisa ethuthukisiwe, iswishi yokudlulisa emile eyenza ithembeke, kanye neshaja/isilungisi sebhethri esinamandla amakhulu kakhulu e-AC-DC. Ibhethri le-UPS eliguqulelwe kabili lilungele okokusebenza okuzwelayo ekushintshashintsheni kwamandla nasezindaweni lapho ugesi uphela khona noma ukucima kuvame.

3. Ulayini Interactive UPS

Lolu hlobo lwe-UPS lusebenza ngokufanayo ku-Standby UPS, kodwa lungalawula ngokuzenzakalelayo i-voltage ngokufaka i-autotransformer yompompi eminingi eguquguqukayo. I-autotransformer ilawula i-voltage ephumayo ingase iphendule ngokwengeza noma ngokukhipha ikhoyili enamandla ukuze ikhulise noma yehlise indawo kazibuthe. Lokhu kuvumela i-Line-Interactive UPS ukuthi iqhubeke ibekezelela i-voltage ephezulu nephansi ngaphandle kokuphuma kwebhethri futhi iqhubeke nokushaja kukho konke ukusebenza. Lolu hlobo lwe-UPS luthuthuke kakhulu kune-Standby UPS, okwenza lubize kodwa luthengeke uma luqhathaniswa ne-Online UPS. Ngaleli bhethri, ungavala ngokuphephile idivayisi yakho ebucayi futhi uyivikele ngesikhathi sokumnyama nokumnyama.

Isiphetho

Kusukela ekubuyekezweni okungenhla, kungasiza ukuqhathanisa izinhlobo zamabhethri e-UPS ukukusiza ukhethe leyo ethembekile ezidingweni zakho. Ngoba sonke isikhathi sibalulekile lapho uphatha ukusebenza kwakho futhi uvikela ihadiwe yakho namadivayisi. Kodwa-ke, lapho uhlungela ibhethri le-UPS, kufanele uqinisekise ukuthi isilinganiso se-VA siyahambisana nesamba somthwalo ohlose ukuwuvikela.
