摘　　要：随着特高压开关类产品的普及,雷电冲击试验中过冲偏大的问题,已成为国内外试验技术人员所关注的热点问题。虽然最新的IEC 60060-1:2010及GB/T 16927—2011标准放宽了对过冲的要求和限制,但是通过近几年特高压开关类产品的雷电冲击试验来看,过冲仍难以控制在10%以内。笔者通过建模仿真,设计开发了参数合理的过冲阻尼装置,并将其应用于雷电冲击试验回路中,有效地抑制了过冲,使得过冲从22%降至5%左右,满足了标准的要求,对实际试验具有一定指导意义。Recent years, the high overshoot problem in the lightning impulse test has become a hot spot technical problem at home and abroad with the popularity of UHV switchgear. The overshoot still can not be restricted within 10~/0 through the experience of the lightning impulse voltage test of UHV switchgear, which is specified as the limits in the latest standards IEC 60060-1：2010 and GB/T 16927--2011. In this paper, the damping device, which is designed and overshoot effectively by being applied to the lightning to about 5% according with the requirement, and the developed by modeling and simulation, can inhibit impulse test circuit. The overshoot reduced from 22% research result are helpful for practical experiment.
