摘　　要：为实现对变电站绝缘子闪络泄漏电流的精准监测,本文以某变电站为例,开展绝缘闪络自动监测方法的设计与研究。首先,布置基于机器视觉的变电站绝缘子在线监测终端;其次,采集与自动监测泄漏电流高速,计算绝缘子闪络等效电阻;最后,通过对比实验,验证方法的先进性。结果表明,该方法在实际应用中效果良好,可精准监测变电站绝缘子闪络前、后的泄漏电流,及时感知绝缘子闪络等异常现象。In order to achieve accurate monitoring of insulator flashover leakage current in a substation,this paper takes a certain substation as an example to design and research on automatic insulation flashover monitoring method.Firstly,the online monitoring terminals of substation insulators based on machine vision are arranged.Secondly,the leakage current is collected at a high speed and monitored automatically,and the equivalent flashover resistance of insulators is calculated.Finally,comparative experiments are carried out to verify the progressiveness of the method.The results show that the designed automatic monitoring method for insulator flashover has a good effect in practical application,can achieve accurate monitoring of leakage current before and after insulator flashover in substations,and timely perceive abnormal phenomena such as insulator flashover.
