摘　　要：目前常用的断路器回路电阻测试仪存在测试时间长、测试接线钳数量多、测试线质量大等缺点,且需要多次测试,工作效率低。对此研制了1种单接线钳、细导线的测试连接线,质量小,便于携带,能够保证测试准确性。实际应用结果显示,首次测试成功率由原来的43.4%提升至94.8%,有效提高了回路电阻测试效率。The present commonly used circuit resistance tester has some shortcomings,such as long test time,large number of test clamps and large weight of test line,which often needs repeated testing.In view of the existing problems,a test connection line of single clamp and thin wire is developed,which is light in weight,easy to carry,and can ensure the accuracy of the test.The application of it shows that the first test success rate is improved from 43.4%to 94.8%,which effectively improves the efficiency of circuit resistance test of switchgear.
