飞来峡泄水闸监控系统防雷改造

Lightning protection upgrade for water release gate supervisory and control system of Feilaixia Hydropower Plant

针对飞来峡电厂泄水闸监控系统经常在雷暴天气后出现故障的问题,在分析原系统易受雷击的原因基础上,有针对性地进行了系统的防雷改造。改造后经两年多运行,泄水闸监控系统从未发生因雷击造成的模块故障,系统运行正常,改造效果显著。

The water release gate supervisory and control system of Feilaixia Hydropower Plant had frequently seenfaults after thunderstorms. In view of this problem, analysis was made on the causes for the control system being lia-ble to lightning stroke, based on which corresponding lightning protection upgrade was conducted. The water re-lease gate supervisory and control system has operate normally without any module fault due to lightning stroke formore than two years since the upgrade was completed, which indicate good upgrade effects.
