摘　　要：故障电弧断路器(AFCI)在国内正处于起步阶段,其研发、生产过程需要进行大量实验,特别是串联型故障电弧实验。该文设计的故障电弧电信号发生器通过电力电子器件取代实际电极装置,模拟产生串联故障电弧试验所需的实际电流信号,提高了实验效率和可重复性。在故障电弧发生过程中,电力电子器件始终处于开启状态,通过栅极电压调控其导通程度从而实现对电流的调控,避免了工作于开关状态导致的谐波。仿真和实物实验表明:所研制的故障电弧电信号发生器能够满足AFCI开发及检测对串联故障电弧电信号的需求。Arc fault circuit interrupter（AFCI）is in its infancy domestically. A lot of experiments need to be conducted in the developing and manufacturing procedure. The arcing fault signal generator designed in this thesis simulates the current of fault arc with power electronic component so as to improve test efficiency and repeatability. During half cycle of grid power,the power electronic com ponent remains open and regulates current passing through by controlling its conduction level,which avoids harmonic current in switching process and transient response of external circuits. Simulation and experiments indicate that the arcing fault signal generator designed is competent in developing and testing application of AFCI.
