轨道电路是实现电气集中、自动控制及远程控制等现代化铁路运输的重要组成部分,对搞好当前运输和将来全面实现铁路运输自动化都具有十分重要的意义。 但轨道电路短路(俗称连电)是工务部门发生的惯性事故之一。以我段为例:全段有自动闭塞线路三百余公里,电气集中道岔八百余组,1977～1978年发生的行车事故中短路事故占57％。如何防止这一事故的发生,是工务部
Railroad track is an important part of modern railway transportation, such as electric concentration, automatic control and remote control. It is of great significance to improve the current transportation and realize the railway transportation automation in the future. However, the short circuit track (commonly known as electricity) is one of the inertial accidents occurred in the public works department. Take the paragraph as an example: The whole section has three hundred kilometers of automatic blocking lines and eight hundred sets of electrical switches, and 57% of the traffic accidents occurred between 1977 and 1978. How to prevent the accident from happening is the Ministry of Public Works
