摘　　要：梨园水电站在500kV GIS断路器导电回路电阻测试中,由于带入两侧接地开关,测试结果存在三相差别大、不满足制造厂和规程要求的情况。为解决此问题,寻求测试结果的准确性与可靠性,通过测试中不断探索,在常规测试方法的基础上探寻到了两种新的测试方法,并通过理论分析以及现场实践证实了测试结果的有效性和合理性。本文对测试方法做出详细介绍和应用分析,为同行测试GIS断路器导电回路电阻提供参考。In the 500kV GIS circuit breaker resistance test of Liyuan Hydropower Station,due to the introduction of grounding switches on both sides,the test results have a large three-phase difference,which does not meet the requirements of the manufacturer and regulations.In order to solve this problem,seek the accuracy and reliability of the test results.Through continuous exploration in the test,two new test methods have been explored on the basis of conventional test methods,and the validity of the test results has been verified through theoretical analysis and field practice.Sex and rationality.This article gives a detailed introduction and application analysis of the test methods,and provides a reference for peer testing of the conductive loop resistance of GIS circuit breakers.
