Indlela yokukhetha nokwahlulela ukuthenga idivayisi yokuvikela ukuhlinza yekhwalithi ephezulu Njengamanje, inani elikhulu labavikeli bokuhlinzwa abasezingeni eliphansi ligcwala emakethe. Abasebenzisi abaningi abazi ukuthi bangakhetha futhi bahlukanise kanjani. Lokhu futhi sekuyinkinga enzima kubasebenzisi abaningi ukuyixazulula. Ngakho-ke ungakhetha kanjani idivayisi efanelekile yokuvikela ukuhlinzwa? 1. Isivikelo sezinga lokuvikela okuhlinzayo Umvikeli ohlinzayo uhlukaniswe ngamaleveli amathathu ngokuya ngendawo okufanele ivikelwe. Umvikeli ohlinzayo wezinga lokuqala angasetshenziswa kukhabhinethi enkulu yokusabalalisa amandla esakhiweni, engakhipha umbani oqondile wamanje, futhi ukukhishwa okuphezulu kwamanje ngu-80KA ~ 200KA; Isivikeli sokuhlinzwa sezinga lesibili sisetshenziswa kukhabhinethi yokusabalalisa amandla e-shunt yesakhiwo. Kuyidivayisi yokuvikela i-voltage ebamba iqhaza yesivikeli sombani esisezingeni elingaphambili kanye nokushaywa kombani okubangelwa umbani endaweni. Ubuningi bokukhipha okwamanje bumayelana ne-40KA; Isivikeli sokuhlinzwa sezinga lesithathu sisetshenziswa ekugcineni kwemishini ebalulekile. Kuyindlela yokugcina yokuvikela imishini. Ivikela i-LEMP kanye namandla asalayo ashaya umbani adlula emayini yokulwa nendiza yezinga lesibili. Isilinganiso esiphezulu sokukhipha amandla singama-20kA. 2, bheka intengo Ungazami ukushibhile lapho uthenga isivikeli sokuhlinza ekhaya. Kungcono ukungasebenzisi izivikeli ezishibhile zokuhlinza emakethe. Lawa mayunithi alinganiselwe ngomthamo futhi ngeke abe wusizo kuma-surges amakhulu noma ama-spikes. Kulula ukushisa ngokweqile, okungabangela ukuthi wonke umvikeli ohlinzayo abambe umlilo. 3. Bheka ukuthi sikhona yini isitifiketi sogunyazo lomhlaba jikelele Uma ufuna ukwazi ikhwalithi yomkhiqizo, udinga futhi ukubona ukuthi unaso yini isitifiketi senhlangano yokuhlola egunyaziwe yamazwe ngamazwe. Uma umvikeli engenaso isitifiketi, kungenzeka kube umkhiqizo osezingeni eliphansi, futhi ukuphepha akunakuqinisekiswa. Ngisho nenani eliphakeme akusho ukuthi izinga lihle. 4, bheka amandla omthamo wokumunca amandla Lapho umthamo wayo wokumunca amandla uphezulu, ukusebenza kokuvikela kuzoba ngcono. Inani lesivikeli osithengayo kufanele okungenani libe ngama-joule angama-200 kuye kwangama-400. Ukuze uthole ukuvikelwa okungcono, abavikeli abanamanani angaphezu kuka-600 joules bangcono kakhulu. 5. Bheka isivinini sokuphendula Izivikeli zokuhlinzwa azivuli ngokushesha, zisabela ekuqhumeni ngokulibaziseka kancane. Uma isikhathi sokuphendula siside, yilapho ikhompuyutha (noma enye idivayisi) izobhekana nokuhlinzwa. Ngakho-ke thenga isivikeli sokuhlinza esinesikhathi sokuphendula esingaphansi kwe-nanosecond. 6. Bheka i-clamping voltage Lapho i-clamping voltage yehla (i-voltage yokuvikela elinganiswa ngemuva kokuthi isivikelo sombani sikhipha amandla noma isimanje), ukusebenza kokuvikela kuba ngcono. Ngamafuphi, ohlelweni lokukhetha umvikeli ohlinzayo, kuyadingeka ukuqaphela umkhiqizo futhi ufunde kabanzi mayelana nokusebenza kwawo kuzo zonke izici. I-Thor Electric igxile ekuvikeleni umbani iminyaka engu-20. Imikhiqizo yayo inezitifiketi ze-CE ne-TUV, futhi inqubo yokukhiqiza ihlolwa kuwo wonke amazinga ukuze kuqinisekiswe ukuthi imishini kagesi yamandla ivikelekile emonakalweni wombani.
