Izindaba

Ingabe kuyadingeka ngempela ukufaka izinto zokuvikela ezihlinzayo ekhaya? Ngikholwa ukuthi abantu abaningi bazoba nemibuzo enjalo. Amaqiniso afakazele ukuthi izingozi zombani zivamile emindenini namuhla, ngakho kuyaphuthuma ukufaka imishini yokuzivikela. Njengamanje, inani elikhulu lamadivayisi okuvikela asezingeni eliphansi atheleleka emakethe, abasebenzisi abaningi abazi ukuthi bangakhetha kanjani futhi bahlukanise, okuye kwaba inkinga enzima kubasebenzisi abaningi bomndeni ukuyixazulula, ngakho-ke ungakhetha kanjani ukuhlinzwa okulungile. idivayisi yokuzivikela?

I-1, Ukuvikelwa kwebanga kwedivayisi yokuvikela ukuhlinzwa

Idivayisi yokuvikela i-Surge (SPD) ihlukaniswe ngamaleveli amathathu ngokuya ngendawo okufanele ivikelwe. I-SPD yezinga lokuqala ingasetshenziswa kwikhabhinethi yokusabalalisa jikelele esakhiweni, engakhipha umbani oqondile wamanje. Isilinganiso esiphezulu sokukhishwa kwamanje ngu-80kA ~ 200kA; Idivayisi yokuvikela i-surge level yesibili (SPD) isetshenziswa kukhabhinethi yokusabalalisa i-shunt yesakhiwo, okuhloswe ngayo ku-voltage yesiboshwa sezinga langaphambili kanye nemishini yokuvikela eyenziwe ngumbani endaweni. Isilinganiso esiphezulu sokukhipha okwamanje singama-40ka; Idivayisi yokuvikela i-surge level yesithathu (SPD) isetshenziswa ekugcineni kwemishini ebalulekile, okuyindlela yokugcina yokuvikela imishini. Ivikela i-LEMP namandla asele ombani adlula kudivayisi yezinga lesibili lokulwa nombani, futhi ukukhishwa okuphezulu kwamanje kumayelana ne-20KA.

2, Bheka intengo

Ungabi nobugovu ukuthenga izinto zokuvikela ezihlinzayo zasendlini. Uma intengo yemishini yokuvikela ekhuphuka ingaphansi kwama-yuan angama-50 emakethe, kungcono ukungawasebenzisi. Amandla alawa madivaysi anomkhawulo impela, futhi awasebenzi kuma-surges amakhulu noma ama-spikes. Kulula ukushisa ngokweqile, bese kubangela ukuthi yonke into evikelayo ibambe umlilo.

3, Bona ukuthi zikhona yini izimpawu zokuphepha

Uma ufuna ukwazi ikhwalithi yomkhiqizo, kuphinde kuncike ekutheni unombiko wokuhlolwa wesikhungo sokuvikela umbani noma isitifiketi sokuphepha komkhiqizo. Uma isivikeli singenalo uphawu lokuhlola ukuphepha, kungenzeka kube umkhiqizo wekhwalithi ephansi, futhi ukuphepha akunakuqinisekiswa. Ngisho noma intengo iphezulu, akusho ukuthi ikhwalithi yinhle.

4. Amandla okumunca amandla

Uma uphakeme umthamo wokumunca amandla, kuba ngcono ukusebenza kokuvikela. Inani lesivikeli osithengayo kufanele okungenani libe ngama-joule angama-200 kuye kwangama-400. Ukuze uthole ukusebenza okungcono kokuvikela, isivikeli esinenani elingaphezulu kwama-joule angu-600 singcono kakhulu.

5. Bheka isivinini sokuphendula

Izivikeli zokuhlinza azinqamuki ngokushesha, zisabela ekuqhumeni ngokulibaziseka kancane. Uma isikhathi sokuphendula siside, yilapho ikhompuyutha (noma ezinye izinto zokusebenza) zizohlupheka ngenxa yokuhlinzwa. Ngakho-ke, kuyadingeka ukuthenga amadivaysi okuvikela okuhlinzwa anesikhathi sokuphendula esingaphansi kwe-nanosecond eyodwa.

6, Bheka i-clamping voltage

Lapho i-clamping voltage iphansi, kungcono ukusebenza kokuvikela. Inamazinga amathathu okuvikela: 300 V, 400 V no-500 v. ngokuvamile, i-clamping voltage iphezulu kakhulu uma idlula i-400 V. Ngakho-ke, inani le-clamping voltage kufanele libhekwe ukuze kuqinisekiswe ukuphepha.

Ngokuvamile, ohlelweni lokukhetha amadivayisi okuvikela okuhlinzwa, imindeni kufanele ibone umkhiqizo futhi yazi okwengeziwe ngokusebenza kwayo kuzo zonke izici. I-Leihao kagesi igxile ekuvikelweni kombani. Imikhiqizo yayo iphumelele ukuhlolwa kokuphepha kwesikhungo sokuvikela umbani, futhi inqubo yokukhiqiza ibhekwa kuwo wonke amazinga, ukuze ugcine umndeni wakho kude nokuhlasela kombani futhi uqinisekise ukuphepha kwemishini ye-electronic yomndeni kanye nokuphepha komuntu siqu.
