AC withstand voltage test ntawm lub transformer yog ib qho kev sim uas ib tug sinusoidal hwj chim zaus AC test voltage tshaj ib tug tej yam ntau yam ntawm cov rated voltage yog siv rau cov kev sim transformer winding ua ke nrog lub bushing, thiab lub sij hawm yog 1min.Lub hom phiaj yog siv qhov ntsuas hluav taws xob siab dua li qee qhov ntau ntawm cov ntsuas hluav taws xob los hloov cov atmospheric overvoltage thiab sab hauv overvoltage los ntsuas qhov kev ua haujlwm ntawm rwb thaiv tsev ntawm lub transformer.Nws yog txoj hauv kev zoo tshaj plaws los txheeb xyuas qhov rwb thaiv tsev lub zog ntawm lub transformer, thiab nws kuj yog ib qho tseem ceeb ntawm kev sim ua haujlwm los xyuas kom meej tias kev ua haujlwm ruaj ntseg ntawm lub transformer thiab tsis txhob muaj qhov tshwm sim ntawm rwb thaiv tsev xwm txheej.AC tiv thaiv qhov ntsuas hluav taws xob tuaj yeem pom cov rwb thaiv tsev tseem ceeb ntawm lub transformer yog damp thiab concentrated defects, xws li tawg ntawm lub ntsiab rwb thaiv tsev ntawm cov windings, xoob windings tsis xws luag xws li hloov chaw, lead rwb thaiv tsev deb tsis txaus, thiab av yog txuas nrog lub rwb thaiv tsev. .AC withstand voltage test yog ib qho kev puas tsuaj hauv kev ntsuas hluav taws xob.Nws yuav tsum tau nqa tawm tom qab lwm qhov kev ntsuam xyuas tsis muaj kev puas tsuaj (xws li kev ntsuas kev tiv thaiv kev tiv thaiv thiab kev nqus qhov sib piv, DC leakage test, dielectric poob kho thiab kev ntsuas roj insulating) yog tsim nyog..Tom qab qhov kev xeem no dhau lawm, lub transformer tuaj yeem muab tso rau hauv kev ua haujlwm.AC withstand voltage test yog ib qho tseem ceeb xeem, Yog li ntawd, cov kev cai tiv thaiv kev ntsuam xyuas qhia tias transformers nrog 10kV thiab hauv qab no yuav tsum tau sim rau AC withstand voltage tom qab 1 ~ 5 xyoo, 66kV thiab hauv qab no tom qab overhaul, tom qab hloov windings thiab thaum tsim nyog.

Txoj kev sim
(1) Cov kab mob
Sab nraud AC tiv thaiv qhov ntsuas hluav taws xob rau cov hluav taws xob me me thiab nruab nrab ntawm lub zog hluav taws xob hauv qab 35kV.Tag nrho cov windings yuav tsum tau kuaj.Thaum lub sij hawm xeem, cov hlau lead ntawm txhua theem winding yuav tsum luv luv-circuited ua ke.Yog tias muaj cov hlau lead ntawm qhov nruab nrab, cov hlau lead yuav tsum tau luv luv nrog peb-theem.
(2) Kev ntsuas hluav taws xob
Tus qauv ntsuas kev xa khoom tau teev tseg tias lub tshuab hloov hluav taws xob uas nws lub peev xwm qis dua 8000kV thiab nws qhov ntsuas hluav taws xob qis dua 110kV yuav tsum raug rau AC tiv thaiv qhov ntsuas hluav taws xob raws li cov qauv ntsuas hluav taws xob tau teev tseg hauv Daim Ntawv Ntxiv I ntawm tus qauv.
Cov kev cai tiv thaiv kev ntsuas tau teev tseg: qhov ntsuas qhov ntsuas hluav taws xob ntawm cov roj-immersed transformers yog cov ncauj lus kom ntxaws nyob rau hauv cov lus qhia (cov kev ntsuas tsis tu ncua hloov cov nqi winding voltage raws li ib feem).Thaum tag nrho cov windings ntawm qhuav-hom transformer yog hloov, qhov voltage tus nqi ntawm lub Hoobkas kuaj yuav tsum tau siv;Thaum lub windings ntawm qhuav-hom transformer yog ib feem hloov thiab kuaj ib ntus, tus nqi voltage ntawm lub Hoobkas kuaj yuav tsum yog 0.85 zaug.
