西林电桥(QS1)测试中常忽视的问题

Problem that often neglect in the high voltage capacitor bridge(QS1)'s test

通过西林电桥(QS1型)对电力设备测试结果可靠性及其试验方法的评价,介绍了在其试验环节存在容易忽视的常见问题,分析了这些问题产生的根本原因,对其试验结果产生的影响进行了具体的说明。根据对电力设备介质损失角正切值tgδ试验的实际,介绍了使用西林电桥(QS1)测量各种电力设备介质损失角正切值tgδ的方法、注意事项及规范要求,并提出如何将各项试验结果全面综合分析判断,对被试设备的绝缘状况和缺陷性质作出科学的结论。

This paper discussed dependability and evaluation of high voltage capacitor bridge used in electric power equipment test and mentioned some problems and causes often occurred. We introduced how to test tgδ of electric power equipment medium using high voltage capacitor bridge and how to analyze the all kinds of examination results.
