Transformer kuyerwa kweDC kuramba chikamu chakakosha cheshanduro bvunzo.Kuburikidza neDC kuramba kuyerwa, zvinogoneka kutarisa kana conductive wedunhu retransformer iri mukubata kwakashata, kushata, kutadza kwecoil uye kukanganisa kwewaya uye nhevedzano yezvikanganiso.
HV Hipot GDZRS akatevedzana matatu-chikamu DC kuramba muyedzo
Iyo inodaidzwa kuti DC kuramba kweiyo transformer inoreva iyo DC kuramba kukosha kwechikamu chimwe nechimwe mhepo yekushandura.Chinangwa chekuyeresa ndechekutarisa kana paine inter-turn short circuit mukati meiyo-nhatu-phase winding ye transformer.Nokuti kana pane chikamu-ku-chikamu chechidimbu chipfupi mukati memushanduri, iyo pfupi-yekutenderera ikozvino ichave yakakura kwazvo, uye inogona kunyanya kupisa kunze kweshanduko.
Zvisinei, kana pane dunhu rakapfupika pakati pekutendeuka kweimwe yezvikamu, nguva pfupi-yekutenderera ikozvino inogona kunge iri duku zvikuru, uye kuchengetedzwa kwegesi kwemushanduri kuchafamba, asi zvakaoma kuona kana transformer pachayo inokanganisa.
Panguva ino, kuyera DC kuramba kukosha kwechikamu chimwe nechimwe cheshanduko, uyezve kuburikidza nekuenzanisa kwezvikamu zvitatu zvekupikisa maitiro, zviri nyore kutonga kana kune inter-turn short circuit mukati.Kana iyo inter-phase kuramba kukosha kwakasiyana zvakanyanya, mukana weiyo inter-turn pfupi-circuit kukanganisa kwakakura kwazvo.Kana kukosha kwekupikisa kwechimwe chezvikamu zvakakura zvikuru kana kunyange zvisingagumi, zvinoreva kuti coil yechikamu ichi yakaputsika.Kana iyo interphase resistances yakangofanana, mukana wepfupi wedunhu pakati pekutendeuka unogona kubviswa.
Kazhinji, kana iyo yakayerwa kugona kweshanduko isina kuchinjika, iyo yakakura iyo DC kuramba, iyo yakakura kurasikirwa nemhangura uye zvakanyanya kukomba kupisa kwetransformer.Kana iyo DC inopikisa yakakurisa, iyo transformer inopisa zvakanyanya, uye iyo transformer inotsva nyore nyore.
