摘要
影响剩余电流保护器准确动作的因素是多方面的。根据剩余电流保护器工作原理,详细分析了剩余电流保护器的动作特性。通过实际案例探讨了剩余电流保护器在工程应用中出现的拒动和误动的原因,并提出了有效的解决方法。
Factors that affect the RCD（residual current protective device） to operate correctly are in many aspects.According to the working principles,the paper analyzes the operating characteristics of RCD in details.Through actual cases,discussing on refusing action of RCD as well as erroneous action in the engineering applications,and some effective solutions are also proposed.
