Ukunikezwa kwamandla okungaphazamiseki noma i-UPS iyisisetshenziswa sikagesi esinganikeza amandla engeziwe aphuthumayo emithwalweni exhunyiwe lapho ukunikezwa kwamandla okuyinhloko kuphazamiseka.Inikwa amandla ibhethri eliyisipele kuze kube yilapho umthombo wamandla omkhulu ubuyiselwa.I-UPS ifakwe phakathi komthombo wamandla ovamile nomthwalo, futhi amandla anikeziwe afinyelela umthwalo nge-UPS.Ngesikhathi sokucima kukagesi, i-UPS izobona ngokuzenzakalelayo futhi ngokushesha ukulahleka kwamandla okufaka amandla amakhulu futhi ishintshe amandla okukhipha ebhethrini.Lolu hlobo lwebhethri eliyisipele ngokuvamile liklanyelwe ukunikeza amandla isikhathi esifushane-kuze kube yilapho amandla ebuyiselwa.
I-UPS ivamise ukuxhunywa ezingxenyeni ezibalulekile ezingakwazi ukumelana nokucisha kukagesi, njengedatha nempahla yenethiwekhi.Zibuye zisetshenziselwe ukuqinisekisa ukuthi umthwalo oxhunyiwe (noma ubalulekile noma cha) uyaqhubeka nokusebenza kahle uma kwenzeka ukuphelelwa amandla.Lawa madivayisi asiza ukuvimbela isikhathi sokuphumula esibizayo, imijikelezo yokuqalisa kabusha enzima kanye nokulahleka kwedatha.
Nakuba igama elithi UPS lamukelwa kabanzi njengelibhekisela ohlelweni lwe-UPS, i-UPS iyingxenye yohlelo lwe-UPS—nakuba iyingxenye eyinhloko.Lonke uhlelo luhlanganisa:
• Imishini ye-elekthronikhi ebona ukulahleka kwamandla bese ishintsha okuphumayo okusebenzayo ukuze kudonswe ebhethrini • Amabhethri anikeza amandla ayisipele (kungaba i-asidi yomthofu noma amanye) • Ishaja yebhethri Imishini kagesi eshaja ibhethri.
Okuboniswa lapha amandla ahlanganisiwe angaphazamiseki noma i-UPS enamabhethri, ama-electronics ashajayo, ama-electronics okulawula ukushaja, namasokhethi okukhiphayo.
Uhlelo lwe-UPS luhlinzekwa ngumkhiqizi njengengxenye ye-in-one (kanye nokhiye wokuvula);izinto zikagesi ze-UPS neshaja kuhlanganiswe emkhiqizweni owodwa, kodwa ibhethri lithengiswa ngokuhlukana;kanye ne-UPS ezimele ngokuphelele, ibhethri nemikhiqizo yeshaja yebhethri.Izingxenye ezihlanganiswe ngokugcwele zonke-in-one zivame kakhulu ezindaweni ze-IT.Amasistimu e-UPS ane-UPS kanye nezinto zikagesi zeshaja ezingenabhethri zivame kakhulu ezindaweni zezimboni ezifana naphansi kwefekthri.Ukucushwa kwesithathu nokungadumile kakhulu kusekelwe ku-UPS ehlinzekwe ngokuhlukile, ibhethri, neshaja yebhethri.
I-UPS iphinde ihlukaniswe ngokohlobo lomthombo wamandla (DC noma AC) ahambisana nawo.Wonke ama-AC UPS enza ikhophi yasenqolobaneni yokulayishwa kwe-AC… futhi ngenxa yokuthi ibhethri eliyisipele liwumthombo wamandla we-DC, lolu hlobo lwe-UPS lungakwazi futhi ukwenza isipele ukulayishwa kwe-DC.Ngokuphambene, i-DC UPS ingakwazi ukwenza isipele izingxenye ezinamandla e-DC.
Njengoba kushiwo ngaphambili, uhlelo lwe-UPS lungasetshenziswa ukwengeza amandla e-DC kanye ne-AC mains.Kubalulekile ukusebenzisa i-UPS efanele yohlobo lokuphakelwa kwamandla kuhlelo ngalunye.Ukuxhuma amandla e-AC ku-DC UPS kuzolimaza izingxenye... futhi amandla e-DC awasebenzi ku-AC UPS.Ngaphezu kwalokho, isistimu ngayinye ye-UPS inamandla alinganiselwe kuma-watts—amandla amakhulu i-UPS engawanikeza.Ukuze unikeze ukuvikeleka okwanele kwemithwalo exhunyiwe, isidingo samandla esiphelele sayo yonke imithwalo exhunyiwe akumele seqe umthamo we-UPS.Ukuze ulungise usayizi we-UPS ngendlela efanele, bala futhi ufingqe izilinganiso zamandla ngazinye zazo zonke izingxenye ezidinga amandla ayisipele.Kunconywa ukuthi unjiniyela acacise i-UPS amandla ayo alinganiselwe angaphezulu okungenani ngo-20% kunengqikithi yesidingo samandla esibaliwe.Okunye okucatshangelwayo kwedizayini kuhlanganisa…
Isikhathi sokusebenzisa: Isistimu ye-UPS yakhelwe ukunikeza amandla engeziwe futhi ayikwazi ukusetshenziswa isikhathi eside.Isilinganiso sebhethri le-UPS sisemahoreni ama-ampere (Ah), sicacisa umthamo nobude bebhethri... Isibonelo, ibhethri elingu-20 Ah linganikeza noma iyiphi yamanje ukusuka ku-1 A amahora angu-20 ukuya kwangu-20 A ihora elilodwa.Hlala ucabangela ubude besikhathi sebhethri uma ucacisa isistimu ye-UPS.
Izisebenzi zesondlo kufanele ziqonde ukuthi ukunikezwa kwamandla okuyinhloko kufanele kubuyiselwe ngokushesha, futhi ibhethri le-UPS alikwazi ukushajwa ngokuphelele.Uma kungenjalo, ibhethri eliyisipele lingase linganele… futhi lishiye umthwalo obalulekile ungenawo amandla nhlobo.Ukunciphisa isikhathi sokusebenzisa ibhethri eliyisipele kungase futhi kunwebe impilo yebhethri.
Ukuhambisana: Ukuze usebenze kahle, ukunikezwa kwamandla, i-UPS, nomthwalo oxhunyiwe kufanele konke kuhambisane.Ngaphezu kwalokho, izilinganiso ze-voltage nezamanje zazo zontathu kufanele zifane.Lesi sidingo sokusebenzisana sisebenza futhi kuzo zonke izintambo ezihambisanayo nezingxenye ezimaphakathi ohlelweni (njengama-circuit breaker nama-fuse).Izingxenye ezingaphansi (ikakhulukazi i-UPS elawula izinto zikagesi namashaja) ohlelweni lwe-UPS olwakhiwe isihlanganisi sesistimu noma i-OEM kumele nazo zihambisane.Futhi hlola ukuthi ingabe izintambo zanoma yimuphi umklamo wokuhlanganiswa kwenkambu onjalo zilungile yini...kuhlanganise noxhumo lwetheminali kanye nokucatshangelwa kwe-polarity.
Yebo, ukuhambisana kwezingxenye ezincane ohlelweni lwe-UPS oludidiyelwe ngokugcwele kuqinisekisiwe ngoba lokhu kuhlolwa umphakeli ngesikhathi sokukhiqiza nokulawula ikhwalithi.
Indawo yokusebenza: I-UPS ingatholakala ezindaweni ezahlukahlukene ezijwayelekile kuya kweziyinselelo enkulu.Umkhiqizi we-UPS uhlala ecacisa izinga lokushisa eliphezulu nelincane kakhulu lokusebenza ekusebenzeni okujwayelekile kohlelo lwe-UPS.Ukusebenzisa ngaphandle kwalobu bubanzi obushiwo kungabangela izinkinga-okuhlanganisa ukwehluleka kwesistimu nokulimala kwebhethri.Umkhiqizi (onesitifiketi, ukuvunyelwa, nokulinganisa) uphinde acacise ukuthi i-UPS ingamelana futhi isebenze ezindaweni ezinomswakama ohlukahlukene, ukucindezela, ukugeleza komoya, ukuphakama, namaleveli ezinhlayiyana.
