漏电断路器性能测试实验台研制

Development of experiment bench for performance test of leakage circuit breaker

研制一套漏电断路器测试实验台,以三相异步电动机为负载,可以测试出电动机工作电流、漏电动作电流和漏电动作时间。测试表明,实验台可以检测出漏电断路器是否合格。

An experiment bench for the test of the leakage circuit breaker is developed.By taking the threephase asynchronous motor as load,the motor＇s working current,leakage action current and leakage action time can be measured.The test shows that the experiment bench can detect whether the leakage circuit breaker is qualified.
