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。

Abstract

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% 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 developed by modeling and simulation

can inhibit overshoot effectively by being applied to the lightning impulse test circuit. The overshoot reduced from 22%to about 5% according with the requirement

and the research result are helpful for practical experiment.
