Dab tsi cuam tshuam rau kev pabcuam lub neej ntawm tus kheej -}} voltage parallel capacitors?
Aug 05, 2025| The actual service life of self-healing low-voltage parallel capacitors often differs from the theoretical value. Qhov sib txawv no tshwm sim los ntawm kev sib xyaw ua ke ntawm ntau yam sab nraud sab nraud thiab sab hauv. To taub cov mob cuam tshuam no tuaj yeem pab cov neeg siv ua kom zoo dua cov kev ua haujlwm thiab ua kom lub neej pabcuam ua haujlwm ntawm cov khoom siv.
I. Kev cuam tshuam ntawm hluav taws xob ua haujlwm tsis muaj hluav taws xob
1. Voltage ntxhov siab ntxhov siab:
Ntev - sij hawm overVoltage nrawm nrawm nrawm ntawm kev laus ntawm nruab nrab.
Hloov pauv ua rau cov kev ntxhov siab rov ua.
Harmonic voltage ua rau sib npaug sib tshooj.
2. Tam sim no thauj khoom tam sim no:
Qhov cuam tshuam tam sim no tau tsim los ntawm cov haujlwm hloov nquag
Ntxiv cov cua kub tsim los ntawm Harmonic qaug cawv
Kev puas tsuaj rau lub metalization txheej tshwm sim los ntawm overcurrent
Ii. Lub luag haujlwm ntawm ib puag ncig cov xwm txheej
1. Cov nyhuv kub:
High - cov kab mob kub ua kom ceev lub detheration ntawm nruab nrab.
Qhov kub sib txawv ntawm ib hnub thiab hmo ntuj ua rau saum npoo av.
Kev ua haujlwm hauv zos overheating ua rau kev tsim ntawm thermal laus cov ntsiab lus.
2. Ib puag ncig cov pa paug:
Corrosive gases yaig lub plhaub sab nraud.
Kev sib txuam ntawm plua plav cuam tshuam cov cua sov dissipation.
Kev npau taws ua kom muaj rwb thaiv tsev.
III. System -} hais txog yam
1. Kev cuam tshuam ntawm cov cuab yeej txhawb nqa:
Kev ua yeeb yam ntawm lub tshuab hloov
Refore parameter txuam nrog degree
Kev ntseeg tau ntawm cov khoom tiv thaiv kev tiv thaiv
2. Cov txheej txheem harmonic:
Harmonic resonance pheej hmoo
High - zaus harmonic penetration nyhuv
Harmonic superposter cua sov
