Nigute ushobora kumenya polarite ya transformateur y'ubu?

Impinduka zubu (CT) nibikoresho byingenzi byamashanyarazi muri sisitemu yingufu.Irashinzwe kwigunga hagati ya sisitemu yo hejuru na ntoya ya voltage hamwe no guhindura voltage nini kuri voltage nto.Niba insinga ari nziza cyangwa idahwitse ningirakamaro cyane mubikorwa bisanzwe byo kurinda, gupima, gupima nibindi bikoresho bya sisitemu.Iyo hashyizweho CT nshya hanyuma umugozi wa kabiri wa CT ugashyirwa mubikorwa cyangwa ugasimburwa, gupima ukuri kwa CT polarite ni inzira yingenzi yakazi kubakozi bashinzwe kurinda relay.Ibikurikira, HV Hipot izerekana ibipimo bya CT polarite muburyo burambuye:

1. Ubuharike bwa CT ni ubuhe?

Polarite nimbaraga za electromotive zatewe na coil primaire hamwe na coil ya kabiri munsi yibikorwa bya magnetiki flux imwe yibyuma.Impera zombi zigera ku bushobozi buke icyarimwe cyangwa iherezo rifite ubushobozi buke icyarimwe byitwa polarite end.

Ibyo bita transformateur ya none (CT) polarite bivuga isano iri hagati yicyerekezo cyubu hagati yumuyaga wambere wacyo no guhinduranya kabiri.Ukurikije amabwiriza, impera yambere ya CT yibanze ihindagurika irangwa na P1, naho umurizo wumurizo ugaragara nka P2;umutwe wumutwe wa kabiri uzunguruka urangwa nka S1, naho umurizo urangira nka S2.Mu nsinga, P1 na S1, P2 na S2 byitwa polarite end.Dufashe ko I1 iriho ubu ihindagurika ryambere ryinjira kuva kumutwe wumutwe P1 hanyuma rigasohoka riva kumurizo wumurizo P2, umuyaga uterwa na I2 mumuzinga wa kabiri usohoka uva kumutwe S1 hanyuma ugatemba uva kumurizo S2.Muri iki gihe, ibintu bya magnetiki biva mu cyuma Mu cyerekezo kimwe, ikimenyetso nk'iki cya CT cyitwa depolarisation.Ibinyuranye, byitwa kongeramo polarite.Ubusanzwe ikoreshwa rya transformateur, keretse niba byavuzwe ukundi, koresha depolarisation.

2. Kuki gupima polarite ya CT?

Ubuharike bwa transformateur yubu bugomba kugeragezwa mbere na nyuma yo guhererekanya no kuvugurura.Byongeye kandi, iyo kurinda itandukaniro mubikorwa, imikorere mibi yo gukingira icyerekezo cyumuriro cyangwa metero ya watt-isaha ihinduwe, polarite ya CT nayo igomba kugenzurwa.Ni ukubera ko niba polarite ya transformateur ihujwe nabi mugihe cyo gukoresha insinga, hazabaho ingaruka zikurikira:

. ndetse bigahungabanya ibikoresho n'umutekano wawe mubihe bikomeye.

.

.

. ibyo rero bizahindura metero.

Kubwibyo, ni umurimo wingenzi cyane gusuzuma neza niba polarite ya transformateur yubu ari yo cyangwa atariyo.
