Hamsa Hukuma A Dabbobi Da H61 Distribution Transformers

1. Hukuma na Lead Wire
Yadda Ake Sani: Yawan kusa da zahiri a cikin tasirin hanyar DC ya kai wajen 4%, ko kuma wata zahiri tana daga cikin jirgin samun hanyar.
Ainihin Tattalin Arziki: Karkashin kudu a sake kawo don tabbatar da wurin da yake hukuma. Don mafi yawan amfani, sake fayyace da kuma sake kafa lalacewar. Lallacewar da suka haɗa da tsari, za su sake haɗa. Idan inganci na lallacewar ba shi ba, ya kamata a sake haɗa (da takamfi). Idan ingancin lead wire ba shi ba, ya kamata a sake haɗa (da takamfi) don bayar da abubuwan da ke bukata.

2. Hukuma na Tap Changer
Yadda Ake Sani: Yawan kusa da zahiri a cikin tasirin hanyar DC a cikin wurare da dama. Idan an samu hanyar da take da jirgin samun hanyar, ana iya cewa switch ta damsa. Idan an samu yawan kusa da zahiri a cikin wurar da dama, ana iya cewa wasu lalacewar sun damsa. Ainihin lafiya mai tsirrai ya nuna cewa ana iya samu hawa da kuma arcing.
Ainihin Tattalin Arziki: Karkashin kudu a sake kawo don tabbatar da wurin da yake hukuma. Idan lalacewar da ke switch ta fi yawan lafiya, yawan amfani, ko kuma arcing mai tsirrai, za su iya sake fayyace, sake kafa, da kuma sake amfani. Idan an damsa sosai, ko kuma an samu ainihin ground discharge a cikin lalacewar, ya kamata a sake haɗa switch. Ground discharge yana iya haifar da wata zahiri na high-voltage winding; idan yake sosai, ya kamata a sake haɗa ko kuma sake haɗa (da takamfi) wata zahiri.

3. Hukuma na Winding
Yadda Ake Sani: Hukumomin winding sun nuna cewa an samu tekuwa da ruwa daga tanki, bulging na tanki, da kuma ainihin lafiya mai tsirrai. Za a iya gano insulation resistance da kuma DC resistance—insulation resistance na "zero" da kuma yawan kusa da zahiri na DC sun nuna cewa winding tana da hukuma.
Ainihin Tattalin Arziki: Karkashin kudu a sake kawo don tabbatar da wurin da yake hukuma. Hukumomin mai tsirrai suna iya sake fayyace don amfani da shi. Hukumomin mai yawa suna buƙata sake haɗa winding. Idan akwai hukuma a cikin tanki, ya kamata a yi ayyukan zamantakewa.

4. Tsara Insulation
Yadda Ake Sani: Ya kamata a yi aiki mai tsari a cikin insulation resistance tests da kuma oil tests a cikin transformer. Yawan kusa da zahiri a cikin abubuwan da aka samu, ko kuma abubuwan da suka haɗa da abubuwan da aka bayyana a cikin "Regulations" sun nuna cewa an samu ruwa, ko kuma performance da oil insulation ta daɗe.
Ainihin Tattalin Arziki: Idan insulation resistance na transformer ta dole, ya kamata a yi drying mai tsari. Idan oil insulation ta daɗe, ya kamata a sake haɗa oil ko kuma a sake sanya. Faulty seals da defective breathers (dehydrating breathers) za su iya sake fayyace.

5. Hukuma na Core
