交流转辙机控制电路常见故障诊断分析方法
Diagnosis and Analysis Method for Common Faults in Control Circuit of AC Switch Machine
摘要
Abstract
In order to diagnose the fault range of the five-wire switch control circuit,this paper proposes an intelligent diagnosis and analysis method for the faults of the five-wire switch control circuit of the switch machine.On the basis of an introduction to the methods for the voltage parameter acquisition of the five-wire switch and the key relay state acquisition of the control circuit,and in view of the relay operation logic,fault diagnosis is carried out for the energizing circuit of the relay and open circuit of control circuit.The fault diagnosis and analysis of the circuit is conducted by using the switch indication voltage.The fault range is determined by monitoring the voltage at the distribution board.The detailed diagnosis process is explained by using the example of switch normal position.Multiple experiments conducted at the training base of Nanning Metro Line 4 have shown that the proposed analysis method can accurately diagnose the causes and range of faults in the five-wire switch control circuit.When a circuit fault occurs,it can assist maintenance personnel to quickly locate the fault point and complete the fault handling.关键词
