Intego nuburyo bwo kugerageza AC ihangane na voltage ikizamini cya transformateur

Transformator AC ihanganira ikizamini cya voltage ni ikizamini aho imbaraga za sinusoidal power frequency AC igeragezwa irenze umubare munini wa voltage yagenwe ikoreshwa kumirongo ya transformateur yapimwe hamwe na bushing, kandi igihe ni 1 min.Intego yacyo ni ugukoresha voltage yikigereranyo irenze iyindi nini ya voltage yagenwe kugirango isimbuze ikirere kirenze ikirere hamwe n’imbere y’imbere kugirango isuzume imikorere yimikorere ya transformateur.Nuburyo bwiza bwo kumenya imbaraga zokwirinda za transformateur, kandi nikintu cyingenzi cyubushakashatsi kugirango imikorere yimikorere ihindurwe kandi birinde impanuka ziterwa.Gukora AC kwihanganira ibizamini bya voltage birashobora kubona ubushuhe hamwe nubusembwa bwibanze muri insimburangingo nyamukuru ya transfert, nko guhinduranya ibyingenzi bikingira, guhinduranya umuyaga no kwimurwa, Intera yo gukingira ntago ihagije, kandi insulasiyo yubahiriza inenge nkumwanda.

HV Hipot GDTF ikurikirana ya kabili inshuro zihinduranya rezonanse ihangane nigikoresho cyo gupima voltage

AC ihanganira ikizamini cya voltage nikizamini cyangiza mugupimisha.Igomba kwipimisha nyuma yizindi bizamini zidasenya (nk'ikigereranyo cyo kurwanya insulasiyo no kugereranya igipimo cyo kwipimisha, ikizamini cyo kumeneka kwa DC, gukata igihombo cya dielectric no kugabanya ibizamini bya peteroli) byujuje ibyangombwa..Nyuma yiki kizamini cyujuje ibisabwa, transformateur irashobora gushyirwa mubikorwa.AC kwihanganira ikizamini cya voltage nikizamini cyingenzi.Kubwibyo, amabwiriza yikizamini cyo gukumira ateganya ko transformateur ifite 10kV na munsi yayo, mumyaka 1 ~ 5, 66kV na munsi yayo, igomba gukorerwa AC kwihanganira voltage nyuma yo kuvugururwa, nyuma yo gusimbuza umuyaga nigihe ikizamini gikenewe.

Uburyo bwo kugerageza

.Imirongo yose igomba kugeragezwa.Mugihe cyikizamini, insinga ziyobora kuri buri cyiciro kizunguruka zigomba kuba zuzunguruka hamwe.Niba ingingo idafite aho ibogamiye ifite insinga ziyobora, insinga ziyobora nazo zigomba kuba izunguruka mugihe gito.

.Amabwiriza yikizamini cyo gukumira ateganya: Agaciro ka voltage yikigereranyo cyamavuta yinjizwamo amavuta arambuye murutonde rwamabwiriza (ikizamini gisanzwe gisimbuza umuyaga uhindagurika igice).Kubyuma byubwoko bwumye, mugihe impinduka zose zasimbuwe, kurikiza agaciro ka voltage yinganda;kubice bimwe byo gusimbuza imirongo hamwe nibizamini bisanzwe, kanda inshuro 0,85 zipima uruganda agaciro.

.

1) Impinduka yikizamini igomba kuba ifite ibikoresho byurugendo rwo kurinda birenze.

2) AC ihanganira ikizamini cya voltage ya transformateur yibice bitatu ntabwo ikeneye gukorwa mubice.Nyamara, insinga zose ziyobora ibyiciro bitatu byumuyaga uhuriweho bigomba kuba bigufi cyane mbere yikizamini, bitabaye ibyo ntibizagira ingaruka gusa kuri voltage yikizamini, ariko birashobora no kubangamira insulire nyamukuru ya transformateur.

3) Amabwiriza yikizamini cyo gukumira yerekana ko kuri transformateur zose zifite insimburangingo ziri munsi ya 66kV, mugihe imiterere yikibanza idahari, gusa ubwubatsi bwo hanze bwihanganira ikizamini cya voltage.

4) Kubihindura amashanyarazi afite ingufu zidafite aho zibogamiye zifite intege nke ugereranije nibindi bice cyangwa izitondekanya amanota, hejuru ya AC yo hanze ishobora kwihanganira ikizamini cya voltage ntishobora gukoreshwa, ariko induction ihanganira ikizamini cya voltage yikubye inshuro 1.3 igomba gukoreshwa.

5) Igomba gupimwa nyuma yo kuzuzwa amavuta yujuje ibyangombwa no kuruhuka mugihe runaka.

6) Kubijyanye na moteri ntoya na ntoya ifite imbaraga zingana na 35kV, voltage yikizamini yemerewe gupimwa kuruhande rwa voltage nkeya ya transformateur yikizamini.Kuri transformateur zifite imbaraga nini, kugirango kugirango ibipimo bibe byuzuye kandi byizewe, hagomba gukoreshwa transformateur ya voltage cyangwa voltmeter ya electrostatike.Ikizamini cya voltage gipimwa muburyo butaziguye kuruhande rwa voltage ndende.

7) Niba gusohora cyangwa gusenyuka bibaye mugihe cyikizamini, hita umanura voltage hanyuma uhagarike amashanyarazi kugirango wirinde kunanirwa kwinshi.
