在本刊1974年第4期《电器误动作的检查与处理》一文中,我们曾分析了几个电器回路公共负线断线后引起的电器误动作的特征。根据这种特征处理故障,消除误动作。这次我想就另外一种断线——一次性多股断线(电器或机械事故造成)的快速恢复办法谈一谈体会,对临修和厂修打线号等会有所帮助。东风2型机车电器线路上的塑料管上的线号已无法确认,导线多年油浸严重老化,有时发生短路一次烧损数根导线,给检修工作带来
In our article, No. 4, 1974, “Inspection and Handling of Electrical Malfunction”, we analyzed the characteristics of electrical malfunction caused by the disconnection of the common negative line of several electrical circuits. According to this feature to deal with failure, eliminating misoperation. This time I would like to talk about another kind of disconnection, one-time multi-strand disconnection (caused by electrical or mechanical accidents), and help with line repair and factory repair. Dongfeng 2 locomotive electrical lines on the plastic pipe line number has been unable to confirm, the wire years of serious oil immersion, sometimes a short circuit burning a few wires, to the maintenance work brought
