Menene manyan abubuwan da ke haifar da gazawar SMC hukumar rufi

(1) Rushewar iskar gas

Lokacin da ƙarfin filin lantarki na SMC hukumar rufi ya zarce ƙima, zai haifar da ɓarna. Idan tazar ta yi ƙanƙanta, ƙarfin filin lantarki zai ƙaru kuma ya haifar da rushewar iskar gas. Yawanci, capacitors suna rushewa saboda matsanancin ƙarfin lantarki da ake amfani da su, da tartsatsin wutar lantarki da ke haifar da wayoyi da suka fallasa, da baka lokacin da aka rufe. Waɗannan sharuɗɗan suna nuna cewa ba su da kayan rufe fuska.

(2) Rushewa tare da saman

A cikin amfani da SMC insulation board, akwai sau da yawa gas ko ruwa kafofin watsa labarai a kusa da m matsakaici, kuma rushewa sau da yawa faruwa tare da dubawa na biyu dielectrics kuma a gefe tare da ƙananan ƙarfin lantarki, wanda ake kira creeping breakdown. Rashin wutar lantarki tare da saman ya yi ƙasa da na dielectric guda ɗaya. A gefen capacitor electrode, insulator a ƙarshen waya ta motar (sanda) yana da wuyar samun fitarwa mai rarrafe, wanda ke haifar da mummunar lalacewa ga rufin kuma yana haifar da gazawa.

(3) Rushewar dielectric ruwa

Ƙarfin wutar lantarki na dielectric ruwa ya fi girma fiye da na gas a ƙarƙashin daidaitattun jihar. Idan man ya ƙunshi datti kamar danshi, ƙarfin wutar lantarki zai ragu sosai, kuma yana da sauƙi ya rushe kuma ya sa kayan da aka rufe su lalace.
