油开关跳闸造成供电停止,特别是过多的跳闸直接影响正常运输,打乱行车秩序。为提高电气化铁路运行的可靠性,我们对宝成铁路(成都——广元段)的五个牵引变电所、一个开闭所,在1980～1981年两年中油开关跳闸次数作了统计,并归纳了各次跳闸原因。从油开关跳闸原因分析,可以看出:经过若干年运营的电气化铁路,绝缘薄弱环节已由接触网、牵引变电所转移到电力机车受电弓瓷
Oil switch trip caused power to stop, especially the excessive trip directly affect the normal transport, disrupting traffic order. In order to improve the reliability of the electrified railway operation, we calculated the number of oil switch trips at two traction substations of Baocheng Railway (Chengdu-Guangyuan section), one opening and closing station, and two years from 1980 to 1981 and Summarized the reasons for each trip. From the oil switch tripping analysis, we can see: After several years of operation of the electrified railway, the insulation link has been weak from the catenary, traction substation to electric locomotive pantograph porcelain
