Yiziphi izinhlobo zokunikezwa kwamandla e-UPS ezihlukaniswa ngokwesimiso sokusebenza? Ukunikezwa kwamandla kwe-UPS okungenakunqandeka kuhlukaniswe ngezigaba ezintathu: i-backup, i-inthanethi kanye ne-inthanethi esebenzisana ne-UPS. Ukusebenza kokunikezwa kwamandla e-UPS kusukela phezulu kuya phansi yilokhu: ukuguqulwa okuphindwe kabili ku-inthanethi, ukusebenzisana ku-inthanethi, uhlobo lokusekela. Intengo ngokuvamile ilingana nokusebenza. Ukuqonda imodi yokusebenza yokunikezwa kwamandla e-UPS kungasiza ekuvikeleni kangcono ukunikezwa kwamandla e-UPS ekunakekelweni kwansuku zonke.
Yiziphi izinhlobo zikagesi ze-UPS ezihlukaniswa ngokwesimiso sokusebenza?
Ukunikezwa kwamandla e-UPS yilokho esivame ukukubiza ngokuthi ukunikezwa kwamandla kwe-UPS okungenakunqandeka. Ukunikezwa kwamandla e-UPS kusebenza ngezindlela ezintathu ezilandelayo:
1. Ukunikezwa kwamandla kagesi kwe-UPS okuyisipele kunikezwa ngqo kusuka kuma-main kuya emthwalweni lapho ama-main ejwayelekile. Lapho ama-main edlula ububanzi bawo bokusebenza noma ukwehluleka kwamandla, ukunikezwa kwamandla kuguqulwa kube yi-inverter yebhethri ngeswishi yokuguqula. Ibonakala ngesakhiwo esilula, ivolumu encane kanye nezindleko eziphansi, kodwa ububanzi bamandla okufaka buncane, amandla okukhipha azinzile futhi ukunemba kubi, kunesikhathi sokushintsha, futhi i-waveform yokukhipha ngokuvamile iyi-square wave.
Ukunikezwa kwamandla kwe-UPS okukhipha i-sine wave backup: okukhiphayo kweyunithi kungaba ngu-0.25KW~2KW. Uma ama-main eshintsha phakathi kuka-170V~264V, i-UPS idlula i-170V~264V.
2. Ukunikezwa kwamandla kagesi e-UPS okusebenzisana ku-inthanethi kunikezwa ngqo kusuka kuma-main kuya emthwalweni lapho ama-main ejwayelekile. Uma ama-main ephansi noma ephezulu, umugqa wokulawula amandla kagesi wangaphakathi we-UPS uyaphuma. Uma amandla kagesi e-UPS engajwayelekile noma ecinyiwe, amandla kagesi aguqulwa abe yi-inverter yebhethri ngeswishi yokuguqula. Ibonakala ngebanga elikhulu lama-voltage okufaka, umsindo ophansi, ivolumu encane nezinye izici, kodwa futhi kunesikhathi sokushintsha.
Ukunikezwa kwamandla e-UPS okusebenzisana ku-inthanethi kunomsebenzi wokuhlunga, ikhono eliqinile lokulwa nokuphazamiseka kwedolobha, isikhathi sokuguqula singaphansi kwama-4ms, futhi umphumela we-inverter uyi-analog sine wave, ngakho-ke ingafakelwa amaseva, ama-router kanye neminye imishini yenethiwekhi, noma isetshenziswe ezindaweni ezinendawo yamandla enzima.
3. Ukunikezwa kwamandla kagesi e-UPS ku-inthanethi, uma ama-main ejwayelekile, ama-main ahlinzeka nge-DC voltage ku-inverter kumthwalo; uma ama-main engajwayelekile, i-inverter inikwa amandla yibhethri, futhi i-inverter ihlala isesimweni sokusebenza ukuqinisekisa ukuphuma okungaphazamiseki. Ibonakala ngebanga elikhulu kakhulu lama-voltage okufaka, ngokuyisisekelo akukho isikhathi sokushintsha kanye nokuqina kwama-voltage okukhipha kanye nokunemba okuphezulu, okulungele kakhulu izidingo zokunikezwa kwamandla aphezulu, kodwa izindleko ezilinganiselwe ziphezulu. Njengamanje, ukunikezwa kwamandla kagesi e-UPS okunamandla angaphezu kwama-3 KVA cishe konke kungukunikezwa kwamandla kagesi e-UPS ku-inthanethi.
Isakhiwo samandla e-UPS aku-inthanethi siyinkimbinkimbi, kodwa sisebenza kahle futhi singaxazulula zonke izinkinga zokuphakelwa kwamandla, njengochungechunge lwe-PS olunezindlela ezine, olukwazi ukukhipha i-AC ye-sine wave emsulwa ngokuqhubekayo ngaphandle kokuphazamiseka, futhi lungaxazulula zonke izinkinga zamandla ezifana nokunyuka, ukukhuphuka, ukugeleza kwemvamisa; kudinga ukutshalwa kwezimali okukhulu, kuvame ukusetshenziswa endaweni yamandla adingakalayo yemishini ebalulekile kanye nesikhungo senethiwekhi.
Izindlela ezine zokusebenza kwe-UPS UPS
Kuye ngesimo sokusetshenziswa, ugesi we-UPS ongaphazanyiswa ungaguqulwa ube izindlela zokusebenza ezine ezahlukene: imodi yokusebenza evamile, imodi yokusebenza kwebhethri, imodi yokusebenza ye-bypass kanye nemodi yokulungisa ye-bypass.
1. ukusebenza okuvamile
Ngaphansi kwezimo ezijwayelekile, umgomo wokuphakelwa kwamandla wesistimu yokuphakelwa kwamandla engaphazanyiswa ye-UPS ukuguqula amandla okufaka e-AC abe amandla aqondile lapho idolobha livamile, bese ushaja ibhethri ukuze kusetshenziswe ukuphazamiseka kwamandla; kufanele kugcizelelwe ukuthi uhlelo lokuphakelwa kwamandla lwe-UPS alusebenzi lapho ugesi uphela, uma i-voltage iphansi kakhulu noma iphezulu kakhulu, ukuqhuma okusheshayo okuzothinta ikhwalithi yamandla yokusebenza okuvamile kwemishini, uhlelo lwe-UPS lusesimweni sokusebenza ukuze lunikeze ugesi ozinzile nohlanzekile wemishini yomthwalo.
2. Ukusebenza kwe-Bypass
Uma ama-main ejwayelekile, lapho amandla e-UPS ebonakala enqwabelana ngokweqile, umyalo we-bypass (owenziwe ngesandla noma ozenzakalelayo), ukushisa ngokweqile kwe-inverter noma ukwehluleka komshini, amandla e-UPS ngokuvamile aphendula umphumela we-inverter ukuze udlule umkhiqizo, okungukuthi, ohlinzekwa ngqo yi-main. Njengoba isigaba semvamisa yokukhipha i-UPS kufanele sifane nemvamisa yama-main ngesikhathi se-bypass, ubuchwepheshe bokuvumelanisa ukukhiya kwesigaba buyasetshenziswa ukuqinisekisa ukuthi umphumela wamandla we-UPS uvumelaniswa nemvamisa yama-main.
3. Ukulungiswa kwe-bypass
Uma ugesi ophuthumayo we-UPS ulungiswa, ukusetha i-bypass ngesandla kuqinisekisa ugesi ojwayelekile wemishini yokulayisha. Lapho umsebenzi wokulungisa usuqediwe, ugesi we-UPS uyaqalwa kabusha, bese ugesi we-UPS uphendukela ekusebenzeni okuvamile.
4. ibhethri elisekelayo
Uma amapayipi amakhulu engajwayelekile, i-UPS izoguqula ugesi oqondile ogcinwe ebhethri ube ugesi oshintshanayo. Ngalesi sikhathi, okokufaka kwe-inverter kuzonikezwa yiphakethe lebhethri, futhi i-inverter izoqhubeka nokunikeza amandla futhi inikeze umthwalo ozoqhubeka nokuwusebenzisa ukuze kufezwe umsebenzi wokunikezwa kwamandla okuqhubekayo.
Ngenhla ukuhlukaniswa kwamandla kagesi angaphazamiseki e-UPS, amandla kagesi e-UPS empeleni ayidivayisi ekhethekile yokunikeza amandla kagesi esetshenziselwa ukuqinisekisa ukuphepha kwamadivayisi kagesi. Uma amapayipi amakhulu esebenza kahle, angadlala indima yokuzinzisa ingcindezi, ukuze kuqinisekiswe ukuphepha kukagesi, uma amapayipi amakhulu enqanyuliwe, kube nengozi yokuwa kukagesi, ingaguqula amandla kagesi okuqala abe yinani elijwayelekile le-voltage lamapayipi amakhulu ukuze inikeze ugesi ophuthumayo.
