利用监测信息实现对道岔故障后功能自动恢复的判断和处理

Using Monitoring Data to Judge and Treat Spontaneous auto Recovery of Switch Faults

在一次道岔故障后功能自动恢复的事件中,通过对微机监测记录的故障电流模拟量曲线,以及继电器开关量状态的分析,结合道岔控制电路进行多方位判断分析及验证,准确找到了造成道岔故障的原因,及时加以克服,消除了隐患,确保了道岔设备的正常运用。

In a spontaneous recovery of switch fault,multi-directional judgment analysis and verification was made to determine the cause of switch failure accurately through using the fault current analog curve recorded by the microcomputer and analyzing the switch status of relays in combination with the switch control circuit.The cause of the fault was overcome in time to eliminate the hidden dangers,ensuring the normal operation of the switch equipment.
