Mwachidule
Izi ndi oyenera m'nyumba 33kV, 35kV, 36kV, AC dongosolo metering ndi chitetezo.
Chogulitsacho chingagwiritsidwe ntchito paokha kapena kuikidwa mu makabati athunthu ndi ma substations.
Transformer yapano imatengera utomoni wapamwamba kwambiri wa epoxy resin, chitsulo chachitsulo chachitsulo cha silicon, mapindikidwe ake amatengera waya wamkuwa wokhala ndi insulation wapamwamba kwambiri, ndipo pakatikati pake ndi chitsulo chimapangidwa ndi pepala lotchingira lapamwamba kwambiri la semiconductor.
Mapangidwe Oyambira
Mapangidwe amagetsi amagetsi ndi ofanana kwambiri ndi a transformer.Ilinso ndi mapindikidwe awiri, imodzi imatchedwa mafunde oyamba ndipo ina imatchedwa kusekondale.Mapiringiro onse awiri amamangidwa kapena kuvulala mozungulira pakati pachitsulo.Pali kutchinjiriza pakati pa ma windings awiri ndi pakati pa windings ndi chitsulo pakati pa chitsulo, kotero kuti pali magetsi kudzipatula pakati pa ma windings awiri ndi pakati windings ndi chitsulo pakati.Pamene thiransifoma yamagetsi ikugwira ntchito, njira yoyamba yokhotakhota N1 imagwirizanitsidwa ndi mzere mofanana, ndipo mphepo yachiwiri ya N2 imagwirizanitsidwa ndi chida kapena kutumizirana mofanana.Choncho, poyeza voteji pamtunda wapamwamba kwambiri, ngakhale kuti magetsi oyambirira ndi apamwamba, yachiwiri ndi yotsika kwambiri, yomwe ingatsimikizire chitetezo cha ogwira ntchito ndi zida.
Kusamalitsa
1. Transformer yamagetsi isanayambike, kuyezetsa ndi kuyang'ana kudzachitika malinga ndi zomwe zafotokozedwa m'malamulo.Mwachitsanzo, kuyeza polarity, gulu kugwirizana, kugwedeza kutchinjiriza, ndondomeko nyukiliya gawo, etc.
2. Wiring wa voltage transformer ayenera kutsimikizira kulondola kwake.Mapiritsi oyambilira amayenera kulumikizidwa molumikizana ndi dera lomwe likuyesedwa, ndipo mafunde achiwiri ayenera kulumikizidwa molumikizana ndi koyilo yamagetsi ya chida cholumikizira cholumikizidwa, chida chotetezera cholumikizira kapena chida chodziwikiratu.Pa nthawi yomweyi, chidwi chiyenera kuperekedwa ku kulondola kwa polarity..
3. Kuthekera kwa katundu wolumikizidwa ku gawo lachiwiri la thiransifoma kuyenera kukhala koyenera, ndipo katundu wolumikizidwa ndi gawo lachiwiri la thiransifoma sayenera kupitirira mphamvu yake yovotera, apo ayi, cholakwika cha thiransifoma chidzawonjezeka, ndipo ndizovuta kukwaniritsa kulondola kwa muyeso.
4. Palibe dera lalifupi lomwe limaloledwa kumbali yachiwiri ya transformer yamagetsi.Popeza kutsekeka kwamkati kwa thiransifoma yamagetsi kumakhala kochepa kwambiri, ngati dera lachiwiri ndi lalifupi, pompopompo yayikulu idzawoneka, yomwe ingawononge zida zachiwiri komanso kuyika chitetezo chamunthu.Voltage transformer ikhoza kukhala ndi fusesi kumbali yachiwiri kuti itetezeke kuti isawonongeke ndi dera lalifupi kumbali yachiwiri.Ngati n'kotheka, ma fuse ayenera kuikidwanso kumbali yoyamba kuti ateteze gululi yamagetsi yamagetsi kuti isawononge chitetezo cha dongosolo loyamba chifukwa cha kulephera kwa mawotchi othamanga kwambiri a transformer kapena mawaya otsogolera.
5. Pofuna kuonetsetsa chitetezo cha anthu pokhudza zida zoyezera ndi ma relays, mphepo yachiwiri ya transformer yamagetsi iyenera kukhazikitsidwa panthawi imodzi.Chifukwa pambuyo pa nthaka, pamene kusungunula pakati pa mawindo oyambirira ndi achiwiri kumawonongeka, kungalepheretse voteji yapamwamba ya chida ndi relay kuti asawononge chitetezo chaumwini.
6. Kuzungulira kochepa sikuloledwa kumbali yachiwiri ya transformer yamagetsi.
