Qhov zoo thiab qhov tsis zoo ntawm qhov sib txawv sau Media rau qis -Voltage Power Capacitor
Dec 17, 2025| Cov khoom ntim khoom rau qis-voltage fais fab capacitors feem ntau suav nrog huab cua qhuav, cov pa roj tsis zoo (xws li nitrogen), roj zaub, roj ntxhia, thiab resin filling. Txawv filling media muaj lawv tus kheej zoo thiab qhov tsis zoo:
Dry Air Filling
Qhov zoo: Cov qauv yooj yim, tus nqi qis, lub teeb yuag, ib puag ncig tus phooj ywg thiab nyab xeeb, tsis muaj kev pheej hmoo ntawm kev xau.
Disadvantages: Tsawg voltage kuj, tsis zoo cua sov dissipation, haum rau me me -muaj peev xwm, low-voltage applications, thiab kuj luv luv kev pab cuam lub neej.
Inert Gas Sau (Nitrogen)
Qhov zoo: Cov hluav taws kub zoo, tsis yog -flammable, zoo rwb thaiv tsev kev ua tau zoo, pab kom ntev lub neej ntawm capacitor.
Qhov tsis zoo: Cov kev xav tau sealing siab, kev ua tau zoo cuam tshuam thaum muaj qhov tshwm sim, tus nqi siab dua li cov cua qhuav, haum rau me me mus rau nruab nrab -sized capacitor.
Zaub roj filling
Qhov zoo: Ib puag ncig tus phooj ywg thiab tsis yog - lom, ua kom sov zoo, muaj peev xwm tiv taus ntau dua voltages thiab loads, nrog rau lub neej ntev.
Qhov tsis zoo: tus nqi siab dua, qee qhov kev xav tau ntawm qhov kub thiab txias, cov roj zaub tuaj yeem degrade raws sij hawm, tsis haum rau qhov kub thiab txias.
Mineral Roj Filling
Qhov zoo: Cov rwb thaiv tsev zoo heev thiab kev ua kom sov dissipation, haum rau loj - muaj peev xwm thiab siab -voltage capacitor.
Disadvantages: Mineral roj yog me ntsis toxicity thiab polluting, poses hluav taws kub, tsis zoo ib puag ncig tus phooj ywg, thiab to tuaj yeem cuam tshuam rau ib puag ncig.
Resin filling
Cov txiaj ntsig zoo: Kev ua haujlwm siab rwb thaiv tsev thiab kev siv tshuab muaj zog, cov qauv muaj zog, muaj peev xwm ua kom haum rau qhov chaw hnyav, haum rau cov qauv tsim compact thiab me me capacitor.
Qhov tsis zoo: Tsis zoo cua sov dissipation, tus nqi siab dua, haum rau lub teeb yuag thiab me me capacitors, nws yooj yim rau kev laus nyob rau hauv siab - load tej yam kev mob.
