铁路信号电源混线是铁路信号设备的一个重要故障隐患。在不清楚电源混线的具体位置时,很难预计其变化情况。也许会在相当长的时间内变化较小,也许在一定时间内会造成电源电气特性更差,造成电源短路,导致信号联锁关系失效,从而危及行车安全。信号系统管理规章规定,电务工作的重点是防止电源接地、混线造成联锁关系失效。这项管理规章强调了以防为主、质量第一的维修原则,因此,探讨电源混线故障的处理方法,对保障铁路安全具有重要意义。
Railway signal power line is an important fault of railway signal equipment. When you do not know the exact location of the power mix, it’s hard to predict the change. May change slightly for a long time, and may cause the power supply to have worse electrical characteristics within a certain period of time, causing the power supply to be short-circuited, resulting in the failure of the signal interlocking relationship, thus endangering traffic safety. Signal system management rules and regulations, the focus of electrical work is to prevent the power grounded, interlocking relationship caused by failure. This management regulation emphasizes the principle of prevention and quality first. Therefore, it is of great significance to discuss how to deal with the fault of the hybrid power line to ensure railway safety.
