摘要(Abstract)：
介绍了配电网低压系统常见故障及相应处理方法,指出传统的排除试送法和兆欧表检测法存在弊端。针对上述问题,设计研制了能够模拟工频交流电并将之作为检测信号的故障检测仪,介绍了检测仪的工作原理、电路设计、整体结构,通过实验室验证及现场使用,表明该故障检测仪可以解决配电网隐性故障排查的难题。
The paper introduces common faults in LV system of distribution networks and the corresponding handling methods. Besides, the paper indicates that there are disadvantages in traditional trial energization method and Megger detection method. Therefore, a fault detector that can simulate power-frequency alternate current and take it as detection signal is designed and developed. The paper introduces work principle, circuit design, and overall structure of the detector. Through verification in lab and field application, it is shown that the detector can help potential fault detection in distribution networks.
