Kufotokozera mwatsatanetsatane chifukwa chosavomerezeka cha SMC insulation board

Pali zifukwa zambiri zakulephereka kwa bolodi yotsekera ya SMC, ndipo chimodzi mwazinthu zovuta kwambiri chimayamba chifukwa cha ukalamba. Ngati atapondedwa ndi zinthu zina pa kutentha kwakukulu, insulator ikhoza kukhala yofupikitsa, zomwe zingapangitse bolodi lotsekera kulephera. Tiyeni tifotokoze mwatsatanetsatane zifukwa zomwe zalephereka.

(1) Kuwonongeka kwa gasi

Mphamvu yamagetsi yamagetsi ya SMC ikapitilira mtengo wina, imayambitsa kuwonongeka. Ngati kusiyana kuli kochepa kwambiri, mphamvu yamagetsi idzawonjezeka ndikuyambitsa kuwonongeka kwa gasi. Nthawi zambiri, ma capacitor amawonongeka chifukwa chamagetsi okwera kwambiri, zoyaka zamagetsi zomwe zimayambitsidwa ndi mawaya owonekera, ndi ma arcs pomwe switch yatsekedwa. Zinthu izi zikuwonetsa kuti alibenso zinthu zotchinjiriza.

(2) Kuwonongeka kwa dielectric yamadzimadzi

Mphamvu yamagetsi ya dielectric yamadzimadzi ndiyokwera kwambiri kuposa ya gasi yomwe ili pansi pa boma. Ngati mafuta ali ndi zonyansa monga chinyezi, mphamvu zake zamagetsi zidzachepetsedwa kwambiri, ndipo zimakhala zowonongeka, zomwe zimayambitsa kulephera kwa zinthu zotetezera.

(3) Kuphwanyidwa pamwamba

Pogwiritsa ntchito bolodi yotchinjiriza ya SMC, nthawi zambiri pamakhala ma gasi kapena media zamadzimadzi kuzungulira sing’anga yolimba, ndipo kusweka kumachitika motsatira mawonekedwe a ma dielectrics awiri ndi mbali ndi mphamvu yamagetsi yotsika, yomwe imatchedwa kuwonongeka kwa zokwawa. Mphamvu yowonongeka pamtunda ndi yotsika kuposa ya dielectric imodzi. Pamphepete mwa capacitor electrode, insulator yomwe ili kumapeto kwa waya wamoto (ndodo) imakhala ndi zokwawa, zomwe zimayambitsa kuwonongeka kwakukulu kwa kutsekemera komanso kumabweretsa kulephera.

Zomwe zili pamwambazi ndikuyambitsa zifukwa za kulephera kwa bolodi la SMC. Poyang’anizana ndi njira zosiyanasiyana zowonongeka, zotsatira zake zapangitsa kulephera kwa bolodi la insulation ndipo silingathenso kuchita ntchito yake yoyenera. Choncho, tiyenera kumvetsera magetsi Kuwongolera kwa zipangizo kumalepheretsa kuwonongeka kosafunikira panthawi yogwira ntchito komanso kumakhudza mphamvu yotsekemera.
