电力电缆绝缘在线监测测量方法及判据设计

On-line Monitoring Measurement Method and Criterion Design of Power Cable Insulation

现阶段我国的电力线路故障比较难鉴别,为了找到简单且实用的电力线路故障鉴别方法,提出了电力电缆以及不同接地点的电缆接地中的电容电流的监测测量方法,以及判定相关的绝缘状况,设计了相关的测量装置,并验证了这种方法以及判据的效果.

At present,it is difficult to identify circuit faults in our country.In order to find a simple and practical method for identifying circuit faults,this paper puts forward the monitoring and measuring methods of capacitive current in grounding of circuit cables and cables with different grounding points and judges the relevant insulation conditions,designs relevant measuring devices,and verifies the effect of this method and criterion.
