Uyini umehluko phakathi kwe-voltage transformer kanye ne-transformer yamanje?

Uyini umehluko phakathi kwama-voltage transformer kanye nama-transformer amanje ngokwemigomo yawo yokusebenza?

I-HV HIPOT GDPT-103 Voltage Transformer Calibrator

Umehluko omkhulu wukuthi isimo sokusebenza sihluke kakhulu ngesikhathi sokusebenza okujwayelekile, okuvezwa ngokuthi:

I-1) I-transformer yamanje ingaba yi-short-circuited okwesibili, kodwa ingavuli;i-voltage transformer ingavuleka-ijikelezwe okwesibili.Umhloli wokuvikela wamanje wesigaba esisodwa unemisebenzi ephelele, futhi umshini owodwa ungaqedela zonke izivivinyo ezisesigabeni esingenhla sohlelo lokusebenza ngesikhathi esisodwa, ngokusebenza okuqinile, isikhathi sokulinganisa, Konke ukuboniswa kwedijithali kwamandla kagesi e-AC kanye ne-DC kanye namanje, enembile futhi ukufunda okunembile, ukusebenza kohlobo lwenkinobho, kulula futhi kuyavumelana nezimo.Kodwa hhayi isifunda esifushane;

2) Uma kuqhathaniswa nomthwalo ohlangothini lwesibili, i-impedance eyinhloko yangaphakathi ye-voltage transformer incane kangangokuthi inganakwa, futhi ingabhekwa ukuthi i-voltage transformer ingumthombo we-voltage;kuyilapho ukumelana okuyinhloko kwangaphakathi kwe-transformer yamanje kukhulu kangangokuthi kungabhekwa ukuthi Kungumthombo wamanje onokumelana okungapheli kwangaphakathi.

3) I-magnetic flux density ye-voltage transformer iseduze nenani lokugcwala lapho isebenza ngokujwayelekile, futhi ubukhulu be-magnetic flux buyancipha lapho iphutha lenzeka;ubukhulu be-magnetic flux ye-transformer yamanje iphansi kakhulu uma isebenza ngokujwayelekile, futhi i-short-circuit current ohlangothini oluyinhloko iba nkulu kakhulu ngesikhathi somjikelezo omfushane, okwenza ukwehla kwamandla kazibuthe.Ubuningi be-flux bukhuphuka kakhulu, ngezinye izikhathi budlula kakhulu inani lokugcwala.
