Kumvetsetsa Kufunika kwa Transformer Neutral Point Grounding Resistance Cabinet mu Power Systems

Pamagetsi adziko langa, gridi yamagetsi ya 6-35KV AC imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti magetsi azikhala okhazikika komanso odalirika kumatauni.Mkati mwa dongosololi, mfundo zopanda ndale zimayendetsedwa kudzera munjira zosiyanasiyana zoyambira pansi monga ma arc kupondereza ma coil, kutsika kwakukulu, komanso kuyika pang'ono.Komabe, njira imodzi yomwe imadziwika bwino kwambiri ndi kusalowerera ndale, komwe kumaphatikizapo kugwiritsa ntchito kabati ya transformer neutral point grounding resistance cabinet.

M'makina amagetsi, makamaka omwe ali ndi zingwe monga mizere yayikulu yotumizira, mpweya wa capacitor wapansi ukhoza kukhala wofunikira, zomwe zimapangitsa kuti pakhale "intermittent" arc overvoltage pansi pazikhalidwe "zovuta".Apa ndipamene njira yosalowerera ndale imayamba kugwira ntchito.Popanga kuwonjezereka kwa nthaka ndikupanga njira yotulutsira mphamvu mu grid-to-ground capacitance, njirayi imalowetsa kukana panopa kumalo olakwika, kuchititsa kuti vuto la pansi lichitike.

The kukana-capacitance katundu wa ndale mfundo kukaniza grounding njira amachepetsa gawo ngodya kusiyana ndi voteji, potero kutsitsa re-kuyatsa mlingo pambuyo mfundo zolakwika panopa kuwoloka ziro.Izi zimaphwanya bwino "zovuta" za arc overvoltage ndikuchepetsa kuchulukirachulukira ku kangapo mphamvu yamagetsi mkati mwa 2.6.Kuonjezera apo, njirayi imatsimikizira kuti chitetezo cha nthaka chimakhala chovuta kwambiri podziwa molondola ndikuchotsa zolakwika zapachiyambi ndi zachiwiri za wodyetsa, potero kuteteza kachitidwe kachitidwe.

Transformer neutral point grounding resistance cabinet imagwira ntchito yofunikira kwambiri pakukhazikitsa njira yosalowerera ndale.Amapereka zowonongeka zofunikira kuti azitha kuyendetsa ndikuwongolera kukana kwapansi, kuonetsetsa kuti mphamvu zamagetsi zimagwira ntchito bwino komanso motetezeka.Pomvetsetsa kufunikira kwa zipangizozi ndi njira yomwe imathandizira, ogwira ntchito zamagetsi amatha kuteteza bwino ku zolakwika zapansi ndikuonetsetsa kuti magetsi akugwiritsidwa ntchito kumadera akumidzi.

Pomaliza, thiransifoma ndale mfundo grounding kukana nduna, mogwirizana ndi ndale mfundo kukaniza grounding njira, ndi chigawo chofunika kwambiri kusunga bata ndi kudalirika kwa machitidwe mphamvu.Ntchito yake yochepetsera kuwonongeka kwa nthaka ndi kuwonjezereka kwamagetsi ndizofunikira kuti zitsimikizire kuti kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake
