Transformer neutral point grounding resistance cabinet

Mu gridi yamagetsi ya 6-35KV AC yamagetsi akudziko langa, pali malo osalowerera ndale, okhazikika kudzera pa ma arc kupondereza ma coil, kukana kwambiri, komanso kukana pang'ono.Mu dongosolo mphamvu (makamaka maukonde maukonde dongosolo mphamvu m'matauni ndi zingwe monga waukulu kufala mizere), pansi capacitive panopa ndi yaikulu, zomwe zingachititse kuti zimachitika "papang'onopang'ono" arc nthaka overvoltage kukhala yeniyeni "zovuta" zinthu, chifukwa arcing Kugwiritsiridwa ntchito kwa njira yosalowerera ndale yotsatizana ndi njira yokhazikitsira mphamvu zowonjezera kumapanga njira yotulutsira mphamvu (charge) mu mphamvu ya grid-to-ground capacitance, ndikulowetsa mphamvu yamagetsi pamalo olakwika, ndikupangitsa kuti vuto loyambira likhalepo. kukana-capacitance chikhalidwe, kuchepetsa ndi The gawo ngodya kusiyana kwa voteji amachepetsa re-kuyatsa mlingo pambuyo panopa pa vuto kuwoloka ziro ndi kuswa "zovuta" chikhalidwe cha arc overvoltage, kotero kuti overvoltage ndi malire mkati 2.6 nthawi yamagetsi yamagetsi, ndipo nthawi yomweyo imatsimikizira chitetezo champhamvu champhamvu chapansi pazida zomwe zimatsimikizira ndikudula zolakwika zazikulu ndi zachiwiri za feeder, motero zimateteza bwino magwiridwe antchito adongosolo.
