Wani Mafi Inganci da Kungiyar Taurari Uku da Turuhu Suna Transformers

A cikin tattalin karamin gagarwa, bushing yana nufin kayayyaki da ya ba ake karkashin karamin gagarwa zuwa shi ne don haka za a iya zama tsari a kan gabashin karamin gagarwa, kamar halin transformers ko circuit breakers. Duk kabilu na transformer suna haɗa da hanyar karamin gagarwar da ke da takawa, saboda haka ya kamata a duba dabara ga abubuwan magana ga mazauna don bincike ƙwarewa daga mazaunuka da ke da takawa zuwa gwamnati na transformer. A cikin transformers na ƙwarewa, ma'anukan suna haɗa da mazaunuka a kan hoton mazaunuka.

Amma a cikin transformers na takawa, duk lokacin suna haɗa da karamin gagarwar da ke da takawa, wanda ya bukatar kayayyaki masu sauyi da ake canza a cikin kalmomin bushing. Bushing yana nufin kayayyakin mai karfi (rod, busbar, ko cable) da kayan aikin mai kyau da ake sanya a cikin wurin gwamnati na transformer, wanda ya kula mazaunuka. Rukunin mafi kyau shine kayan aikin mai kyau da ake ciwo da aikin mai karfi a kan fili. Wannan rukuni ana amfani da shi a kan takawar da suka rage da 33 kV, akwai karamin gagarwar da ke da takawa ta hanyar karamin gagarwar da ke da takawa.

A cikin transformers na gaba, ƙarin (babban) bushing yana da sheds don inganta ƙwarewa daga ruwa a ranar jiki. A cikin transformers na takawar da suka rage da 36 kV, ana amfani da bushing na oil-filled ko capacitor-type. Bushing na oil-filled yana nufin kayan aikin mai kyau da ake ciwo da oil a kan fili. Fili da ke da oil yana kula mazaunuka, wanda babu da shi a kan oil na tanki na transformer. Babban bushing yana haɗa da small expansion chamber don inganta yanayin fili saboda wahalar karamin gagarwar. Ana samun provision a kan ƙarin hoton bayan bushing don current transformers, wanda yake iya kawo bushing bayan ake fuskantar current transformer.

Bushing na capacitor yana nufin layers na synthetic resin-bonded paper da thin metallic foils impregnated with conductive material. Wannan yana nufin series na capacitors, har da karamin gagarwar da ke da takawa. Ta hanyar rubuta tsari na metallic foils da thickness na resin-bonded paper layers, dielectric stress yana kula mazaunuka a kan radial depth—i.e., along the radius of the bushing.
