Intego nuburyo bwikizamini cya AC ihangane na voltage ikizamini cya transformateur

AC ishobora kwihanganira ikizamini cya voltage ya transformateur ni ikizamini aho imbaraga za sinusoidal power frequency AC test voltage irenze umubare munini wa voltage yagenwe ikoreshwa kuri transformateur yapimwe ihindagurika hamwe na bushing, kandi igihe ni 1min.Ikigamijwe ni ugukoresha voltage yipimishije irenze umubare munini wumubyigano wagenwe kugirango usimbuze ikirere kirenze ikirere hamwe n’imbere yimbere kugirango dusuzume imikorere yimikorere ya transformateur.Nuburyo bwiza cyane bwo kumenya imbaraga zokwirinda za transformateur, kandi numushinga wingenzi wubushakashatsi kugirango ukore neza transformateur kandi wirinde ko habaho impanuka ziterwa.AC ishobora kwihanganira ikizamini cya voltage irashobora gusanga insulasiyo nyamukuru ya transformateur itose kandi ifite inenge yibanze, nko gutobora insulasiyo nyamukuru yizunguruka, guhindagurika kwangiritse Inenge nko kwimurwa, intera ikingira intungamubiri ntabwo ihagije, kandi umwanda wometse kumurongo. .AC ihanganira ikizamini cya voltage nikizamini cyangiza mugupimisha.Igomba gukorwa nyuma y’ibindi bizamini bidasenya (nk'ikigereranyo cyo kurwanya insulasiyo no kugereranya igipimo, ikizamini cya DC gisohoka, gukosora igihombo cya dielectric hamwe no gupima amavuta)..Nyuma yiki kizamini cyatsinzwe, transformateur irashobora gushyirwa mubikorwa.Ikizamini cya AC cyihanganira voltage nikizamini cyingenzi, Kubwibyo, amabwiriza yikizamini cyo gukumira ateganya ko impinduka zifite 10kV na munsi zigomba kwipimisha AC zihanganira voltage nyuma yimyaka 1 ~ 5, 66kV na hepfo nyuma yo kuvugurura, nyuma yo gusimbuza umuyaga nigihe bibaye ngombwa.

Uburyo bw'igerageza

(1) Gukoresha insinga

AC yo hanze ishobora kwihanganira ibizamini bya voltage kubikoresho bito n'ibiciriritse bingana na 35kV.Imirongo yose igomba kugeragezwa.Mugihe cyikizamini, insinga ziyobora kuri buri cyiciro kizunguruka zigomba kuba zuzunguruka hamwe.Niba hari insinga iyobora ahantu hatabogamye, insinga ya sisitemu nayo igomba kuba izunguruka mugihe gito.

(2) Kugerageza Umuvuduko

Ikizamini cyo gutanga ihererekanyabubasha giteganya ko transformateur ifite ubushobozi buri munsi ya 8000kV kandi ifite ingufu zingana n’umuvuduko uri munsi ya 110kV igomba gukorerwa AC kwihanganira ikizamini cya voltage ukurikije igipimo cy’ibizamini cya voltage kiri ku mugereka wa I w’ibipimo.

Amabwiriza yikizamini cyo gukumira ateganya: agaciro k'igeragezwa agaciro ka transfert zashizwe mumavuta arambuye murutonde rwamabwiriza (ikizamini gisanzwe gisimbuza umuyaga uhindagurika ukurikije igice).Iyo impinduka zose zo mu bwoko bwa transformate yumye zasimbuwe, hazakoreshwa agaciro ka voltage yikizamini cyuruganda;iyo guhinduranya imashini yumye yumye isimbuwe igice kandi ikageragezwa mugihe runaka, agaciro ka voltage yikizamini cyuruganda kizaba inshuro 0,85.
