Mitundu ya mayeso otulutsa pang'ono ndi malo oyenera

Pakhoza kukhala kukhetsa pang'ono mu insulation sing'anga wa zida mphamvu mu zingwe zatsopano zopangidwa kapena zingwe mu ntchito yaitali.Kuti muzindikire zolakwika zotere ndikuwonongeka mwachangu, kuyezetsa pang'ono kwa zingwe kumatha kupewa ndikupeza zovuta ndikuyimitsa kutayika munthawi yake.pewani zotayika zina.

Mitundu ya mayeso otulutsa pang'ono ndi malo oyenera?
Amagwiritsidwa ntchito kwambiri pozindikira kutulutsa kwapang'onopang'ono kwa zingwe zamphamvu kwambiri za 110kV ndi kupitilira apo, pogwiritsa ntchito zida zosonkhanitsira zizindikiro kuchokera pabokosi loyika chingwe, ndikusankha mitundu yoyesera yosiyana malinga ndi malo ndi zosowa, zomwe zitha kugawidwa m'mitundu 4. :
① Kulimbana ndi mayeso a voltage partial discharge.Gwirizanani ndi zida zoyezera ma voliyumu apamwamba kwambiri monga kutembenuza pafupipafupi kapena ma resonance angapo, ndikuyesa kutulutsa pang'ono panthawi yomaliza chingwe kapena mayeso anthawi zonse.
② Mayeso odziwika bwino.Gwiritsani ntchito masensa oyezera monga HFCT, high-frequency capacitive arm, foil membrane electrode, ndi zina zotero kuti muyese kutulutsa pang'ono kwa chingwe.
③ Kuwunika kwa PD pa intaneti.Zida zodziwira zimayikidwa pa malo oyesera kuti awonetsere zizindikiro zenizeni za nthawi yeniyeni.
④ Odwala kwambiri.Chipangizocho chitha kukhazikitsidwa pamalowo kuti chiwunikire machitidwe a chingwe cha PD pa intaneti pakusamalidwa kwakanthawi kochepa kapena kwanthawi yayitali.
