一、概述韶山1型电力机车在石家庄-太原电气化复线区段运行四年来,机车车顶高压部分对车顶盖放电现象、受电弓支持瓷瓶和主断路器瓷瓶闪络烧损经常发生。石家庄电力机务段运用36台机车,四年来共发生车顶放电105台次,太原北机务段仅1982年9月～1983年元月就发生35台次。这种高电压对车顶部件绝缘距离的击穿,轻则烧损车顶上的高压配件,石家庄电力机务
I. Overview Shaoshan 1-type electric locomotives in the section of Shijiazhuang - Taiyuan electrified double-track operation for four years, part of the car roof high voltage discharge phenomenon of the roof, pomezt support porcelain vats and the main circuit breaker flashover burning often occur. Shijiazhuang Electric locomotive depot using 36 locomotives, roof discharge occurred over the past four years, 105 units, Taiyuan North Depot only in September 1982 ~ January 1983 occurred 35 times. This high voltage breakdown of the roof insulation distance, ranging from burning high-pressure parts on the roof, Shijiazhuang Electric Machinery
