摘　　要：结合项目研发的需求,提出设计F型混合剩余电流信号发生器的需要,通过对IEC 62423标准的分析,明确混合电流组成成分的频率及比例,根据掌握的现有知识,通过Multisim电路仿真软件对RC桥式振荡电路及比例加法电路进行仿真分析,确定了方案的可行性,最后完成发生器的实际设计、调试,可用于对B型RCCB混合剩余电流特性的摸底测试。According to the demands of R＆D project, this paper proposes the design need of signal generator for Type F composite residual current. Firstly, the frequency andproportion of the composite residual current is confirmed through analysis of IEC-62423 standard. Then,on the basis of current knowledge, this paper verified the feasibility of the method by simulating the RC-Wien-bridge and proportion adder circuit with simulation software Multisim. Finally,the signal generator that can be used to verify the operation of Type B RCCB in case of composite residual current is designed.
