摘要:
目的：为了诊断及定位八线制道岔控制电路的故障范围，提出一种交流转辙机八线制道岔控制电路故障诊断分析方法。方法：介绍了八线制道岔功率、电压、控制电路关键继电器状态、表示电压的采集方法；对道岔表示电路进行故障分析，当1DQJ(1启动继电器)未吸起时，判断道岔故障在表示电路，根据所采集到的分线盘表示电压进行故障范围判断，介绍道岔在定位及反位时的详细判断流程；对道岔启动电路进行故障分析，分为道岔操动后未动作故障、动作过程中故障及动作完成后故障三部分介绍相应的故障诊断方法。结果及结论：多次试验结果表明，所提故障分析方法可以准确诊断出八线制道岔的故障原因，以及定位故障范围。
Abstracts:
Objective: To diagnose and locate the fault range in eightwire turnout control circuit, a fault diagnosis and analysis method for the above circuit of AC switch machine is proposed. Method: The power, voltage, control circuit key relay status, and indication voltage acquisition method of the eightwire turnout are introduced. When carrying out fault analysis for the turnout indication circuit, the nonactivated status of 1DQJ (1st starting relay) leads to judgment of faults in indication circuit. Based on the collected indication voltage of the branch panel, the fault range is determined，and the detailed judgment process for turnout in the located and reverse positions is explained. In fault analysis on turnout starting circuit, the diagnosis methods are introduced corresponding to three parts: failure to actuate after turnout operation, faults during the actuation process, and faults after the actuation is completed. Result & Conclusion: Results of multiple tests show that the proposed fault analysis method can accurately diagnose the fault causes and locate the fault range for the eightwire turnouts.
