摘要
剩余电流动作保护器(RCD)是保障人身和财产安全的重要保护电器,但在我国对其选用还存在一些待商榷之处。就电子式RCD的拒动、直流分量影响以及防接地电弧火灾RCD的I值的确定等问题进行了分析和探讨。
Residual current protective device （RCD） is one important protector for personal safety and property safety. There are many questions should be debated in the selection of residual current protective device. Some problems were analyzed and discussed, such as failure to actuate electronic mode RCD, DC component influence, determination of RCD＇ s I△n value used for preventing from grounding arc fire.
