摘　　要：介绍一种紧凑型 4/ 10μs冲击电流发生器用于氧化锌电阻片的大电流耐受试验。用充气式场畸变火花开关控制 ,可适应 2 0～ 110 k A的电流要求而不调节间隙距离。开关噪声小 ,工作稳定。Described a compact 4/10 μs impulse current generator used for the withstand test of ZnO varistor passing heavy current. A filling gas field distortion spark gap with low noise was used to control the discharge of generator. It is not necessary to adjust the distance between the electrodes in the current range of 20~110 kA. The device works steadily and has been used to the arrester test in manufactory.
