Panogona kunge paine kuburitswa kwechidimbu mumudziyo wekudzivirira wemidziyo yemagetsi mumatambo achangogadzirwa kana tambo mukushanda kwenguva refu.Kuti uone kukanganisa kwakadaro uye kuparara nekukurumidza, bvunzo dzekuburitsa patambo dzinogona kudzivirira nekuwana matambudziko uye kumisa kurasikirwa nenguva.dzivisa kumwe kurasikirwa.
GDYT akatevedzana chikamu discharge-Mahara bvunzo mudziyo
HV Hipot GDYT yakatevedzana chikamu chekuburitsa-Mahara bvunzo mudziyo
Mhando dzeyedzo yekuburitsa chikamu uye nzvimbo dzakakodzera?
Inonyanya kushandiswa pakuona kuburitswa kwechikamu chetambo dzakakwirira-voltage ye110kV uye pamusoro, uchishandisa maturusi kuunganidza masaini kubva kune tambo yekumisa bhokisi, uye sarudza mhando dzakasiyana dzebvunzo zvinoenderana nenzvimbo yesaiti uye zvinodiwa, izvo zvinogona kunyanya kukamurwa kuita 4 mhando. :
① Kumirisana nevoltage partial discharge bvunzo.Batira pamwe neakakwira-voltage inomira magetsi ekuyedza senge frequency kutendeuka kana akateedzana resonance, uye ita chikamu chekuyeresa chekuyeresa panguva yekupedzisa tambo kana bvunzo dzenguva dzose.
② Rarama yekuona bvunzo.Shandisa masensa ekuyeresa akadai seHFCT, high-frequency capacitive arm, foil membrane electrode, nezvimwewo kuyera chidimbu chakachajwa kubuda kwetambo.
③ Online PD yekutarisa.Midziyo yekuona inoiswa panzvimbo yekuyedza yechokwadi-nguva chikamu chekuburitsa chiratidzo chekutarisa.
④ Kuchengetwa kwakanyanya.Chishandiso ichi chinogona kuiswa pa-saiti kuti chitarise tambo PD mafambiro pamhepo kwenguva pfupi kana yenguva refu-yakanyanya kutarisirwa.
