摘要(Abstract):

介绍电容型设备绝缘在线监测的测量原理、电流和电压采样方式的选择原则,讨论了2组不同运行年限的线路电流互感器介质损耗在1周内随温度、湿度的变化情况,指出了电流互感器介质损耗变化受温度和湿度的影响具有个体差异性。
This paper introduces the measuring principles of insulation on-line monitoring for capacitive high-voltage apparatus,the sampling and type selection of current and voltage.The changes of dielectric loss in two groups of current transformers varying with ambient temperature and humidity within 1 week during different operating years are discussed.It points out that the influence of ambient temperature and humidity on dielectric loss of current transformers has an evident individual difference.
