| Abstract: | 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. |
