摘要
针对机车主电路过压保护电容器CH84和CH69A承受谐波过电流能力差的弱点,对其进行了结构改进,使之能耐受各种谐波过电压和过电流,并克服了全部油浸式电容器渗漏油的缺点。
To counter the defects on capacity of harmonic current overload,type CH84and CH69A capacitors for main cir cuit over-volt age-pro tecting in elec tric lo comotives are improved in con struction.The capacitors with new constructure have thorough ly re moved the defects of the old ones and also have removed the defects of oil leaking for oil im pregnated capacitors.
