Momwe mungapewere zovuta za overvoltage panthawi ya ntchito ya substation

Pogwiritsa ntchito transformer yopanda katundu, padzakhala chinthu chosapeŵeka chakuthupi, ndiko kuti, kudula.Vuto lakugwiritsa ntchito mopitilira muyeso chifukwa cha kudulidwa kwa wowononga dera litha kupewedwa potengera izi:

1. Sinthani pakati pachitsulo

Kuwongolera pachimake chachitsulo kumakhala ndi zotsatirapo zina pakuchepetsa kusanyamula katundu.Chifukwa magnetizing panopa ndi chitsulo imfa panopa pamodzi kupanga palibe katundu panopa, ndi magnetizing panopa kupanga maginito flux, ndi chitsulo pakati imfa adzachititsa chitsulo imfa panopa, kotero chitsulo pakati pa thiransifoma ndi chinthu chofunika kwambiri kuchepetsa kusanyamula katundu panopa.Kupititsa patsogolo kamangidwe kapakati komanso kuwongolera mtundu wachitsulo ndi njira ziwiri zofunika.Mbewu zoziziritsa kuzizira zitha kugwiritsidwa ntchito m'malo mwa zitsulo zachitsulo za silicon, chifukwa maginito otulutsa maginito ambewu zoziziritsa kuzizira ndizokwera kwambiri.Transformer ikasinthidwa, pachimake chachitsulo chimayenera kuyang'aniridwa ndikuwunikiridwa mosamalitsa malinga ndi miyezo yoyenera.

2. Mamphepo amatengera mtundu wopindika

                                                               HV HIPOT GDB-P automatic transformer imatembenuza chiyerekezo

Transformer ya 220kV ndi core transformer.Ngati njira yokhotakhota ikugwedezeka, mphamvu ya parasitic ya thiransifoma idzawonjezeka.Mapiringidwe omangika ndikulowetsanso kutembenuka kwina kokhotakhota molunjika pakati pa matembenuzidwe amagetsi oyandikana, kotero kuti mphamvu yotalikirapo ya mafunde kumawonjezeka, ndipo kusiyana komweku kungathe pakati pa matembenuzidwe oyandikana kudzawonjezeka, kotero kuti pamaso pa Kukachitika. cha chodabwitsa cha overvoltage, magetsi oyambira amatha kugawidwa mofanana pakati pa matembenuzidwe.

3. Gwiritsani ntchito chosinthira chokhala ndi chopinga chofanana

Panthawi yodulidwa, mphamvu ya maginito mu inductor idzasinthidwa kukhala mphamvu yamagetsi kuti iwononge capacitor.Panthawiyi, ngati chosinthira chikugwirizana mofanana ndi resistor, mphamvu ya maginito mu inductor ikhoza kumasulidwa.Pambuyo posinthana ndi kukana kofanana kutsekedwa kusanadulidwe komweko, kukana kofananirako kumakhala kofupikitsa.Pambuyo pa kudulidwa kwaposachedwa, chosinthiracho chimatchingira chopinga cha R84Th N kuti chipange chapano, kuti mphamvu ya maginito mu inductor iwonongeke.
