Dab tsi yog qhov tseem ceeb uas ua rau tsis ua haujlwm ntawm SMC rwb thaiv tsev board
Dab tsi yog cov yam tseem ceeb uas ua rau tsis ua haujlwm ntawm SMC rwb thaiv tsev pawg thawj coj saib
(1) Kev tawg ntawm cov pa roj
Thaum hluav taws xob teb lub zog ntawm lub SMC rwb thaiv tsev pawg thawj coj saib tshaj ib qho nqi, nws yuav ua rau qhov sib txawv. Yog tias qhov sib txawv me dhau lawm, lub zog hluav taws xob hauv hluav taws xob yuav nce ntxiv thiab ua rau cov roj tawg. Feem ntau, cov capacitors tawg vim yog qhov siv hluav taws xob ntau dhau, hluav taws xob hluav taws xob tshwm sim los ntawm cov xov hlau raug, thiab cov arcs thaum lub qhov hluav taws xob kaw. Cov xwm txheej no qhia tias lawv tsis muaj cov khoom insulating lawm.
(2) Kev tawg raws qhov chaw
Nyob rau hauv kev siv ntawm SMC rwb thaiv tsev board, feem ntau muaj roj los yog kua xov xwm nyob ib ncig ntawm cov khoom nruab nrab, thiab kev puas tsuaj feem ntau tshwm sim nyob rau hauv lub interface ntawm ob dielectrics thiab nyob rau sab nrog qis hluav taws xob zog, uas yog hu ua creeping breakdown. Qhov hluav taws xob tawg nyob rau saum npoo yog qis dua li ntawm ib qho dielectric. Nyob rau ntawm ntug ntawm lub capacitor electrode, lub rwb thaiv tsev ntawm qhov kawg ntawm lub cev muaj zog hlau (qws) yog qhov ua rau nkag mus, uas ua rau muaj kev puas tsuaj loj rau cov rwb thaiv tsev thiab ua rau tsis ua haujlwm.
(3) Kev tawg ntawm cov kua dielectric
Lub zog hluav taws xob ntawm cov kua dielectric ntau dua li cov pa roj raws li lub xeev tus qauv. Yog tias cov roj muaj impurities xws li ya raws, nws lub zog hluav taws xob yuav raug txo qis, thiab nws yooj yim tawg thiab ua rau cov khoom siv rwb thaiv tsev tsis ua haujlwm.
