Cov ncauj lus kom ntxaws qhia txog qhov tsis raug cai ntawm SMC rwb thaiv tsev board

Muaj ntau qhov laj thawj rau qhov tsis ua haujlwm ntawm SMC rwb thaiv tsev pawg thawj coj saib, thiab ib qho ntawm cov tseem ceeb tshaj plaws yog tshwm sim los ntawm kev laus. Yog hais tias nws yog kneaded los ntawm lwm yam khoom nyob rau hauv high kub, lub insulator yuav luv luv Circuit Court, uas yuav ua rau lub rwb thaiv tsev board tsis ua hauj lwm. Cia peb muab cov ncauj lus kom ntxaws txog cov laj thawj ntawm qhov ua tsis tiav.

(1) Kev tawg ntawm cov pa roj

Thaum lub zog hluav taws xob hluav taws xob ntawm SMC rwb thaiv tsev board tshaj qhov muaj nqis, nws yuav ua rau muaj 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 qhov siv hluav taws xob ntau dhau, cov 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 tau hais tias lawv tsis muaj cov khoom rwb thaiv tsev lawm.

(2) Kev tawg ntawm cov kua dielectric

Lub zog hluav taws xob ntawm cov kua dielectric yog ntau dua li cov roj hauv lub xeev tus qauv. Yog hais tias cov roj muaj impurities xws li ya raws, nws lub zog hluav taws xob yuav raug txo kom tsawg, thiab nws yuav ua rau tawg, ua rau tsis ua hauj lwm ntawm cov khoom insulating.

(3) 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.

Cov saum toj no yog cov lus qhia txog cov laj thawj rau qhov tsis ua haujlwm ntawm SMC rwb thaiv tsev board. Nyob rau hauv lub ntsej muag ntawm ntau txoj kev tawg, cov txiaj ntsig tau ua rau qhov tsis ua haujlwm ntawm cov rwb thaiv tsev thiab tsis tuaj yeem siv nws qhov kev ua tau zoo. Yog li ntawd, peb yuav tsum xyuam xim rau cov khoom siv hluav taws xob Kev tswj hwm ntawm cov cuab yeej tiv thaiv kev puas tsuaj tsis tsim nyog thaum lub sijhawm ua haujlwm thiab cuam tshuam rau kev rwb thaiv tsev.
