Mfundo yofunika

Pamene thiransifoma yamagetsi ikugwira ntchito bwino, mphamvu yamagetsi ya magawo atatu yamagetsi imakhala yofanana, ndipo kuchuluka kwa mphamvu yamagetsi yamagetsi pagawo lachitatu ndi ziro.Kukhazikika kwa gawo limodzi kukachitika, gawo losalowerera ndale lidzachotsedwa, ndipo voteji ya zero-sequence idzawonekera pakati pa ma terminals a katatu kuti apange relay kuchitapo kanthu, motero kuteteza mphamvu yamagetsi.Mphamvu ya zero-sequence ikamawonekera mu coil, zero-sequence maginito flux imawonekera pachimake chachitsulo chofananira.Kuti zimenezi zitheke, atatu gawo voteji thiransifoma utenga mbali goli pachimake (pamene 10KV ndi pansi) kapena atatu single-gawo voteji thiransifoma.Kwa mtundu uwu wa thiransifoma, kulondola kwa koyilo yachitatu sikuli kwakukulu, koma kumafuna makhalidwe ena owonjezera (ndiko kuti, pamene mphamvu yowonjezera yowonjezera, mphamvu ya maginito yowonongeka muzitsulo zachitsulo imawonjezeka ndi maulendo angapo popanda kuwonongeka).

Chifukwa chiyani muyenera kusintha voliyumu pamzere?Izi zili choncho chifukwa molingana ndi mikhalidwe yosiyanasiyana yopangira mphamvu, kutumiza ndi kugwiritsira ntchito magetsi, ma voltages pamizere ndi osiyana ndi kukula kwake, ndipo kusiyana kwake ndi kosiyana kwambiri.Ena ndi otsika-voltage 220V ndi 380V, ndipo ena ndi ma volt masauzande masauzande ambiri kapena mazana masauzande a volts.Kuti muyeze mwachindunji ma voltages otsika komanso okwera kwambiri, ndikofunikira kupanga ma voltmeter otsika kwambiri komanso apamwamba kwambiri ndi zida zina ndi ma relay malinga ndi kukula kwa voteji mzere.Izi sizidzangobweretsa zovuta zazikulu pakupanga chidacho, koma chofunika kwambiri, sizingatheke komanso zoletsedwa mwamtheradi kupanga chida chapamwamba kwambiri ndikuyesa voteji mwachindunji pamzere wapamwamba kwambiri.

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.
