Abstract：Aiming at the complicated problem of arc signal acquisition in building fault arc research, an AC/DC series arc fault generation device is developed based on fault arc fire. The device is composed of mechanical fault arc generator, control and state detection module, signal acquisition module, main circuit and control circuit and upper computer. In order to solve the problems of difficulty in starting arc and short arc time during arc simulation, the control program of upper computer adopts double closed-loop proportional integral differential (PID) control strategy, and adds sensor-assisted control on the basis of it to improve the operating performance of arc burning device. Many experiments show that the device can produce fault arc under different experimental currents, and the arc burning time can reach the set time. Meanwhile, the device can collect the fault arc voltage and current waveform for the study of fault arc detection technology.
