Cholinga ndi njira yoyesera ya AC kupirira mayeso amagetsi a transformer

Mayeso a AC kupirira voteji ya thiransifoma ndi mayeso omwe sinusoidal mphamvu pafupipafupi AC mayeso voteji kupitirira angapo angapo oveteredwa voteji amagwiritsidwa ntchito kuyesedwa kwa thiransifoma yokhotakhota pamodzi ndi bushing, ndipo nthawi ndi 1min.Cholinga chake ndi kugwiritsa ntchito voteji yoyezetsa kwambiri kuposa ma voliyumu angapo ovotera kuti alowe m'malo mopitilira mumlengalenga ndi kupitilira kwamkati kuti awone momwe thiransifoma imagwirira ntchito.Ndi njira yothandiza kwambiri yodziwira mphamvu yotchinga ya thiransifoma, komanso ndi ntchito yoyesera yofunikira kuti titsimikizire kuti thiransifoma ikugwira ntchito motetezeka ndikupewa kuchitika kwa ngozi zachitetezo.Mayeso a AC kupirira magetsi amatha kupeza kuti kusungunula kwakukulu kwa thiransifoma kumakhala konyowa komanso zolakwika zambiri, monga kung'amba kwa kutsekeka kwakukulu kwa ma windings, ma windings otayirira Zolakwika monga kusamuka, mtunda wotsogolera wotsogola ndi wosakwanira, ndipo dothi limamangiriridwa ku kutchinjiriza. .Kuyesa kwamagetsi kwa AC ndi kuyesa kowononga pakuyesa kwa insulation.Iyenera kuchitidwa pambuyo poti mayesero ena osawononga (monga kukana kwa insulation ndi kuyesa chiŵerengero cha mayamwidwe, kuyezetsa kutayikira kwa DC, kuwongolera kutayika kwa dielectric ndi kuyesa kwamafuta otenthetsera) ali oyenerera..Pambuyo pa mayesowa, thiransifoma ikhoza kuyikidwa kuti igwire ntchito.Kuyeza kwa AC kupirira ma voltage ndi mayeso ofunikira, Chifukwa chake, malamulo oyesera odziletsa anena kuti ma transfoma okhala ndi 10kV ndi pansi akuyenera kuyesedwa ngati AC kupirira voteji pakatha zaka 1 ~ 5, 66kV ndi pansi pambuyo pokonzanso, mutasintha ma windings komanso pakafunika.

Njira yoyesera

(1) Mawaya

Kunja kwa AC kupirira mawaya oyesera magetsi ang'onoang'ono ndi apakatikati amagetsi otsika pansi pa 35kV.Ma windings onse ayenera kuyesedwa.Pakuyesa, mawaya otsogola a gawo lililonse lopindika ayenera kufupikitsidwa pamodzi.Ngati pali waya wotsogola pamalo osalowerera ndale, waya wotsogolera uyeneranso kukhala waufupi wozungulira ndi magawo atatu.

(2) Kuyesa kwa Voltage

Muyezo woyezetsa ma handover umanena kuti thiransifoma yomwe mphamvu yake ili pansi pa 8000kV komanso yomwe mphamvu yake yoyendera ili pansi pa 110kV iyenera kuyesedwa ndi AC kupirira voteji molingana ndi muyeso wamagetsi oyesedwa mu Appendix I ya muyezo.

Malamulo oyeserera oletsa amanenera: mtengo wamagetsi oyesera a ma transfoma omizidwa ndi mafuta akufotokozedwa mwatsatanetsatane patebulo lamalamulo (mayeso okhazikika amalowa m'malo mwa mtengo wamagetsi opumira malinga ndi gawolo).Pamene ma windings onse a transformer yowuma asinthidwa, mtengo wamagetsi wa kuyesa kwa fakitale udzagwiritsidwa ntchito;pamene ma windings a thiransifoma wowuma amasinthidwa pang'ono ndikuyesedwa nthawi ndi nthawi, mtengo wamagetsi wa mayeso a fakitale udzakhala nthawi 0,85.
