Ukumelana nokuhlolwa kwe-voltage ingxenye ebaluleke kakhulu yokulawulwa kwekhwalithi ye-capacitor, futhi iyasebenza nama-capacitors ezokuphepha.Phakamela uvivinyo lwe-voltage, owaziwa nangokuthi uhambisana nokuhlolwa kwamandla kagesi, kuyinkomba ebalulekile yokuhlola ukuqina kanye nokwethenjwa kwezinto zokufaka amandla ngaphansi kwamandla kagesi aphezulu.Umnyombo walesi sivivinyo ukuthola amandla amakhulu kagesi wenkambu kagesi impahla efakwayo engamelana ngaphandle kokudala umonakalo.Enqubweni yokuhlola uqobo, i-capacitor yezokuphepha ibekwa ngaphansi kwamandla kagesi acacisiwe futhi igcinwe isikhathi esithile.Ithuluzi lokuhlola lizosebenza ngokuzenzakalelayo noma linqume ngesandla i-test voltage ngemuva kokufinyelela isikhathi esinqunyelwe kusengaphambili.Uma i-capacitor yezokuphepha yephuka ngesikhathi sokuhlolwa, okungukuthi, okwamanje idlula inani lamanje lokuvikelwa, ithuluzi lokuhlola lizosusa amavolumu futhi likhiphe i-alamu ezwakalayo futhi ebonakalayo ukuvikela ukulimala okwengeziwe kwesampula.
Inhloso yokuhambisa ukubhekisisa kwe-voltage voltage inezinkomo eziningi.Owokuqala ukuvivinya ukumelana nokumelana namandla okuphepha kwama-capacitors okuphepha ngaphansi kokusebenza kwamandla kagesi noma izimo zokuqinisekisa ukuqinisekisa ukusebenza kwazo ukuphepha ezinhlelweni ezisebenzayo.Okwesibili, lokhu kuhlolwa kungabheka ukukhiqizwa kwe-insulation noma ikhwalithi yokulungisa imishini kagesi futhi kuqede ukulimala okungenzeka kokusebenza kokufakwayo ngezinto zokwakha, ukucubungula, ngaleyo ndlela kunciphisa izinga lokuhluleka komkhiqizo.Ngaphezu kwalokho, isivivinyo futhi sifaka ukubheka ukukhishwa kukagesi kanye nebanga le-creeplage lokufakelwa ukuze kuqinisekiswe ukwethenjwa komkhiqizo.
Lapho wenza izivivinyo, umhloli we-volatage we-voluta angaphendula ngokushesha lapho i-capacitor yezokuphepha yephuka, inqunywe ukunikezwa kwamandla futhi izwakale i-alamu.Le nqubo isiza ukunquma ukuthi i-capacitor yezokuphepha ingamelana nokuhlolwa okucacisiwe kwe-dielectric amandla vivinya.Lokhu kuhlola kungakwenza ngokunembile, ngokunembile, ngokushesha nangokwethembekile ukuhlola izinkomba zokusebenza kukagesi ukuphepha okufana nokukhuthazela kweVoltage Ukukhuthazela, ukuqhekeka kwegesi kanye nokuvuza kwamanje kwe-capacitor ehlolwe.Ngasikhathi sinye, futhi kungaqhuba ukuhlolwa okuhlukahlukene kokusebenza kwe-dielectric ngezindlela ezahlukahlukene ezifana nemvamisa yamandla, i-DC, ukuhlinzwa, kanye ne-rose wave ngokuya nge-IEC noma amazinga okuphepha kazwelonke ukuqinisekisa ukuthi ama-capacitos ezokuphepha ahambisana namazinga okuphepha afanele.
