从60年代我国第一条电气化铁路在我局宝凤段开通至今,电气化铁路有了突飞猛进的发展,截至到1993年底,我局铁路电化运营里程已达2950公里,占全局营业里程的49.2%。局内几条大干线(定成、襄渝、阳安、太焦、陇海、京广)先后电化,有力的缓解了我局运能和运量的矛盾。随着电气化铁路的发展,我局的牵引供电设备逐年激增,供电设备的运行、检修、试验、化验队伍不断壮大,到1993年底,我局已开通牵引变电所58座,开闭所16座,分区亭29座,运行、检修、试验、化验人员已达1570人。但是,30余年来,变电设备的检修体制一直沿用我国电化初期采用的周期检修制,这期间我局变电专业的广大职工虽从实践中摸索总结出不少切合实际的检修经验,但由于受管理体制的束缚,始终没有得 Since the first electrified railway of our country was opened in Baofeng section of our bureau in the 1960s, the electrified railway has made rapid development. As of the end of 1993, the railway electrification mileage of our bureau reached 2,950 km, accounting for 49.2% of the total business mileage. Bureau of several major lines (Dingcheng, Xiangyu, Yangan, too coke, Longhai, Beijing-Guangzhou) has electrified, effectively alleviate the contradiction between the capacity and capacity of our bureau. With the development of electrified railway, the traction power supply equipment of our bureau surged year by year. The operation, maintenance, testing and testing of power supply equipment have been continuously expanding. By the end of 1993, our bureau has opened 58 traction substations, 16 open and close stations , Partition kiosks 29, run, overhaul, test, laboratory staff has reached 1570 people. However, over the past 30 years, the maintenance system of substation equipment has been following the periodic maintenance system adopted by China’s initial electrification. During this period, most workers of our substation professional worked out and summed up many practical maintenance experiences. However, Under the shackles of the management system, never got it
