摘 要： 根据GB 16917.1-2003、GB 14048.2-2008 标准规定，漏电断路器除了需要验证在空载下的动作特性之外，还需在带载下通以额定电流，验证其动作特性的正确性。用“漏电开关兼容试验装置”和“剩余电流动作断路器测试仪”验证漏电断路器N 相是常通时，在带载下的剩余电流动作时间测量。通过试验分析，发现所测几组的动作时间存在很大差异的原因，并提出有效的解决方案，以便能更加准确测量试验数据。

Abstract: According to the standards of GB 1691 7.1-2003 & GB 14 048.2-2008, in addition to take tests of operating characteristics under no-load condition, residual current circuit breakers should be taken tests under on-load condition as well to verify the validity of operating characteristics. Leakage current switching compatibility testing device and residual current circuit breaker tester were used to verify the measurement of residual current operating time under on-load with uninterrupted neutral phase of residual current circuit breakers. Analysis of experiments shows the reason why the operate time is quite different, and a very valid solution is proposed to measure testing data more accurately.
Key words: residual current circuit breaker; on-load; operate time; neutral phase
