Isetshenziselwa ukuvikela ukukhuphuka kwamasekhethi kagesi, okokusebenza kwamandla kanye nezimbobo zamandla zamanye amadivaysi kagesi; cindezela i-overvoltage yesikhashana, khipha i-impulse current, futhi usungule isistimu ye-equipotential. (Idivayisi yokuvikela umbani weleveli 1. Idivayisi yokuvikela umbani wokunikezwa kwamandla kagesi. Idivayisi yokuvikela umbani yeleveli 3.)
Idivayisi yokuvikela umbani wesignali isekelwe ezicini zesistimu yesignali, inezinzuzo zokulahlekelwa okuncane kokufaka, isivinini sokuphendula esisheshayo, ukugoqa okunembile, i-voltage eyinsalela ephuma kancane ephumayo, njll., nokusebenza okuphakeme kokudlulisela. (Idivayisi yokuvikela umbani yenethiwekhi ekabili-kokukodwa. Lawula idivayisi yokuvikela umbani wesignali. Idivayisi yokuvikela isignali yombani yevidiyo. Idivayisi yokuvikela umbani wesignali yomsindo. Idivayisi yokuvikela isignali yombani we-antenna).
Idizayinelwe ngokuhambisana nezidingo zokuvikela umbani zamabhokisi okuhlanganisa ama-multimedia endlini yesimanje, ingavikela izisetshenziswa zokuxhumana zasendlini kanye nezinto zokusebenza zemultimedia emonakalweni odalwe umbani.
Isixhumi esikhethekile sangaphandle (i-SSD/SCB) somvikeli ohlinzayo, esinokuzinza okuhle nokuthembeka okuphezulu. (Yenza isipele)
Iwaranti yomkhiqizo ibalulekile
Ukubuka Komkhiqizo
Ulayini we-N kanye nomugqa we-PE wesistimu kuhlanganiswe umugqa we-PEN ukusuka ohlangothini lwe-low-voltage ye-transformer. Kule ndawo, isivikelo sokuhlinza (3P) kuphela esidinga ukufakwa phakathi komugqa wesigaba nolayini wePEN. Ngemva kokungena ebhokisini lokusabalalisa eliyinhloko lesakhiwo, Umugqa we-PEN uhlukaniswe umugqa ongu-N ^ umugqa we-PE kanye nezintambo ezizimele. Ulayini we-PEN uxhunywe kubha yebhasi ephansi ye-equipotential evamile esakhiweni ukuze ixhumeke emhlabeni.
Ulayini we-N kanye nomugqa we-PE wesistimu uxhumeke kuphela ekugcineni kwe-outlet ohlangothini lwe-low-voltage ye-transformer futhi ixhunywe phansi. Ngaphambi kokungena ebhokisini lokusabalalisa elijwayelekile lesakhiwo, umugqa we-N kanye nomugqa we-PE uxhumeke ngokuzimela, futhi umugqa wesigaba kanye nomugqa we-PE kufanele uxhunywe Faka umvikeli wokuhlinzwa.
Umugqa ongu-N walesi simiso usekelwe kuphela endaweni engathathi hlangothi ye-transformer, futhi umugqa ongu-N kanye nomugqa we-PE kuhlukaniswe ngokuqinile. Ngakho-ke, kuyadingeka ukufaka umvikeli ohlinzayo phakathi komugqa wesigaba kanye nomugqa we-N, futhi umvikeli wohlobo lokushintshwa ovame ukufakwa phakathi komugqa we-N nomugqa we-PE.
Iphoyinti elingathathi hlangothi le-transformer yalesi simiso alisekelwe phansi, futhi kukhona intambo engu-N emugqeni.
