试验接线对断路器高压试验的影响

Impacts of Test Connection on Circuit-Breaker High-Voltage Test

高压试验接线对试验结果的影响很大,接线出现问题容易造成测试异常或结果失真。以断路器回路电阻测试和断口并联电容器的电容量/介损测试为例,介绍了接线原因引起测试结果异常的排查过程,分析了测试结果失真的原因。试验异常时的分析和处理过程可供开展类似试验项目时参考。

High-voltage test connection has great impacts on test results and wiring problems are easy to make test abnormal or lead to the distorted result. Taking circuit-breaker circuit resistance test and shunt capacitor＇s capacitance /dielectric loss test as an example, this paper introduced the examination process of abnormal test result due to wiring causes, analyzing the distorted test result, which provided as references for carrying out similar test items.
