Transformer winding deformation inoreva shanduko isingadzokerike muhukuru uye chimiro chekumonereka pasi pechiito chemichina nemagetsi.Inosanganisira kuchinja kweaxial uye radial dimensions, kutama kwemuviri, kuputika kwemhepo, kuputika uye inter-turn shorts, etc. Chikonzero ndechokuti transformer inofanira kutsungirira zvakasiyana-siyana zvenguva pfupi-mapfupi uye mapfupi-madunhu pakubuda panguva yekushanda.Kunyanya kukuvadza kune transformers.

Kunyange zvazvo muparadzi wedunhu anogona kukurumidza kubvisa kukanganisa kupfupi-redunhu mudunhu, iyo otomatiki mudziyo kazhinji haishande nekuda kwechimwe chikonzero, kuitira kuti iyo transformer coil inoremara munguva pfupi kwazvo pasi pechiito chepfupi-redunhu ikozvino. kupisa, magetsi, uye kunyange yakakomba interphase short-circuit uye The winding inopiswa;panguva imwecheteyo, transformer inogonawo kubhurwa uye kukanganiswa panguva yekufambisa uye kuisa, zvichikonzera deformation, tambo dzakatyoka, kutama, kusunungura uye zvimwe zviitiko.
Chii chiri chinangwa chetransformer winding deformation test?
A: Mhepo deformation injodzi huru yakavanzika kune kushanda kwakachengeteka kwemasisitimu emagetsi.Mumakore achangopfuura, nekuwedzera kwekugona kwesimba remagetsi, iyo pfupi-yedunhu simba iri kuwedzera zvakare, uye mhepo inokuvadza tsaona inokonzerwa nepfupi-yedunhu mutsara unobuda zvakare iri kuwedzera.
Mushure mokunge mhepo yekushandura yakasvibiswa, yekutanga ndiyo shanduko yekudzivirira kure kana kukanganisa kwepepa rekudzivirira.Kana overvoltage inosangana, iyo windings ichava ne-inter-cake kana inter-turn breakdown, kana pasi pechiito chekushanda kwenguva refu yevoltage, kukanganisa kwekudzivirira kuchawedzera zvishoma nezvishoma, pakupedzisira kuchitungamirira kune transformer.Kukuvadzwa: Chechipiri, mushure mekunge mhepo yakaremara, michina inodzikira.Kana tsaona pfupi yedunhu ikaitika zvakare, nekuti haigone kumira nesimba rakakura rekuita, tsaona yekukuvadza inoitika, uye inogona kushanda kwenguva yakati rebei.
Transformer winding deformation ndechimwe chezvikonzero zvakakosha zvekukuvara kwetransformer.Mayedzo emagetsi akajairwa akadai sekuyerwa kuyerwa, shanduko yechiyero kuyerwa, uye capacitance kuyerwa kwakaoma kuwana mamhepo deformation, izvo zvinonyanya kutyisidzira kushanda kwakachengeteka kwegidhi remagetsi.Nokuda kwechikonzero ichi, zvakakosha zvikuru kuona uye kuongorora deformation ye transformer windings inotungamirirwa nemagetsi uye magetsi.
