摘要:
［目的］ZDJ9双机牵引提速道岔电动转辙机控制电路中1DQJ是瞬时吸起式继电器，在室外转辙机电路不构成回路的情况下，即在故障情况下，1DQJ继电器仅仅保持约1s的短暂吸起状态。技术人员在处理故障点时一般采用万用表测量，数字型万用表在1s内只能短时间闪烁一次，并且最大显示数据约为170V；指针式万用表在1s内指针只能小幅度摆动一下，也仅仅摆动到120V左右。因此无法对故障点进行详细查找。另一方面，该控制电路采用380V三相交流电源，在查找故障过程中会出现380V电源打火现象，因技术人员有畏惧心理，导致故障查找慢，费时费力费人工，安全性大打折扣。针对当前存在的常见问题进行了创新性研究，提出了具有针对性的故障诊断装置及故障诊断方法。［方法］用3个200W灯泡组合成一个灯泡诊断装置，共用一个接地极，另外的极性连接A、B、C三相电源。利用1DQJ继电器的瞬间吸起连通灯泡，如果亮灯表示电路无故障，如果灭灯表示有故障。详细阐述了利用A、B、C三相电源查找故障的方法。［结果及结论］所提出的故障点诊断装置和故障诊断方法能够准确快速诊断出该控制电路故障点，而且大大提高了故障诊断中的安全性。
Abstracts:
［Objective］ In the ZDJ9 double-machine traction speed-up turnout electric switch control circuit, 1DQJ is an instantaneous suction relay. When the outdoor switch circuit does not form a loop, that is, in the event of a fault, the 1DQJ relay only maintains a short-term suction state for about 1s. When dealing with the fault point, technicians usually use a multimeter to measure. A digital multimeter can only flash once for a short period of time within 1 second, and the maximum displayed data is about 170 V; the pointer of a pointer multimeter can only swing slightly in 1 second, and it only swings to about 120 V, making it impossible to conduct a detailed search for the fault point. On the other hand, the control circuit adopts a 380 V three-phase AC power supply, which may ignite during the troubleshooting process. Due to the fear of technicians, the troubleshooting is slow, time-consuming, labor-intensive, and safety is greatly compromised. Innovative research is conducted on the common problems currently existing, and targeted fault diagnosis devices and methods are proposed. ［Method］ Three 200W light bulbs are combined to form a bulb diagnostic device, sharing one grounding electrode, and the other polarity is connected to the A, B, and C three-phase power supply. The bulbs are connected by the instantaneous suction of the 1DQJ relay. If the light is on, it means that there is no fault in the circuit. If the light is off, it means that there is a fault. The method of finding faults using the A, B, and C three-phase power supply is explained in detail. ［Result & Conclusion］ The proposed fault point diagnosis device and method can accurately and quickly diagnose the fault point of the control circuit and greatly improve the safety in fault diagnosis.
