铁路信号两路电源的合环倒路分析

The Brief Discussion on the Closed Loop in Circuit of the Railway Signal Power Supply

本文根据现场的运行经验,对铁路信号等重要行车负荷两路电源的合环倒路情况进行了介绍和分析,认为自闭、贯通线路的合环倒路,不仅要投入"检同期"保护,还应进行合环选跳,并指出要根本解决电源短时停电对铁路信号等重要行车负荷供电的影响,应采取通过EPS不间断电源的方式供电。

According to the operation experience of the field, this paper introduces and analyzes the closed ring loop of the main circuit in combined power supply of railway signal and other important circuit load. It is not only to be put into ＂check the same period＂ protection, but also to make the loop Tripping selection operation in power supply of railway signal. And pointed out that the power supply should be adopted uninterruptible type in the way of the EPS.
