最近几年,铁道电气化发展很快,电力机务段愈来愈多,但由于检修技术还跟不上去,电力机车上一些电气设备不能做到合理地检修与保养,给生产运输带来一定困难,其中受电弓滑板偏磨就是电力机务段尤其是新建段常见的现象。滑板偏磨可导致如下后果: 1.增加了滑板碎修次数; 2.由于要消除偏磨,维修人员经常用锉刀将偏磨的滑板锉平,因而造成滑板不必要的消
In recent years, the electrification of railway has been developing rapidly with more and more electric locomotive depots. However, due to overhauling technology, some electric equipment on electric locomotive can not be properly repaired and maintained, which brings some difficulties to production and transportation. Among them, the pantograph skateboard wear is a common phenomenon in the electric locomotive depot, especially in the new section. Skateboard partial wear can lead to the following consequences: 1. Increased the number of skateboard broken repair; 2. To eliminate partial wear, maintenance personnel often use the file will be partial wear skateboard file, resulting in unnecessary skateboard
