摘　　要：研究分立元件式剩余电流保护器(RCD)剩余动作电流与控制板元器件温度之间的关系,分析影响剩余动作电流变化的主要因素,设计控制板温度补偿电路,并根据试验结果讨论电路改进前后的剩余动作电流变化情况。对提高RCD控制板工作的稳定性和RCD产品的可靠性起到一定借鉴作用。This paper presented an experimental investigation of the relationship between temperature and residual operating current of residual current device(RCD).The variation of the temperature of the electronic components in RCD has negative effects on the rated residual operating current according to the test data.It is proved that the temperature compensating processes of control circuits RCD increase the operational reliability of RCD.

关 键 词：剩余电流保护器 温度 剩余动作电流 可靠性
