摘要
在高压供配电系统投入运行前,必须对高压电气设备进行必要的绝缘试验。对于分级绝缘的电气设备,利用三倍频感应耐压试验进行绝缘检测是施工现场普遍采用的方法。以电压互感器的感应耐压为例,讲述三倍频感应耐压的基本原理及应用,并对有关注意事项进行了分析与总结。
Before the high-voltage power supply system into operation,the necessary insulation test for high-voltage electrical equipment must be carried out For the graded insulation of electrical equipment,the three times frequency induced voltage tests on site insulation test is widely used.Taking voltage transformer induction voltage test for example,the basic principles and application of the three times frequency induction voltage test are described,and the notes are analyzed and summarized.
