摘要
水电站一次系统的防雷保护措施比较完善,而二次系统的防雷保护工作却没有得到足够重视,以至于常常出现水电站的微机保护系统、通信系统等二次设备遭受雷电的危害。介绍了雷电入侵水电站二次系统的各种途径,并结合实例给出了水电站二次系统的几种防雷保护措施。
The lightning protection measures of primary system in hydropower station are quite perfect,but that of secondary system has not yet been paid enough attention to.So it is often the case that the secondary equipments such as microcomputer protection system and communication system suffer lightning stroke.Different ways of lightning invasion to secondary system of hydropower station are introduced.Some preventive measures against lightning are proposed for secondary system with practical examples.
