摘要：Loop resistance is an important technical indicator reflecting the performance and operating status of high-voltage circuit breakers. The traditional test method requires at least one side of the grounding switches of the circuit breaker be opened, and the field operation needs to wait for the dispatch approval, so the work efficiency is extremely low. According to the actual requirements of on-site measurement of high-voltage circuit breakers, a test method and test scheme have been proposed in this paper for measuring loop resistance by using the double-ended grounding technology. At the same time, according to the structural characteristics of high-voltage circuit breaker, the test deviation between the method and the traditional test method is analyzed and compared. Finally, it is concluded that the test method for measuring the loop resistance through using the double-ended grounding technology can fully meet the actual needs of the project.
