浅谈水电厂微机和远动装置的防雷保护

A Brief Discussion about Lightning Protection of Microcomputer and RTU in Hydroelectric Systems

随着微机和远动装置在电厂的不断普及,电厂的防雷工作面临着更大的挑战。尽管大部分电厂都采取了一定的防雷措施,但仍常出现雷害事故。以近年来发生在福建三明斑竹水电厂的雷害现象为例,详细分析了微机设备屡遭雷害的原因和远动载波系统受雷害特别严重的原因,提出了有效的整改措施和预防建议。这对电厂、变电站和其它企业具有重要的参考价值。

Lightning protection is faced with greater challenges due to wildly appliance of microcomputers and RTU in hydroelectricy.Although a certain amount of measurements have been adopted to protect hydropower plants from lightning strikes,lightning accidents still happen frequently.Taking several cases of lightning strikes happened in Sanming Banzhu Hydroelectric Company in recent years as samples,this paper firstly puts forth the analyzations in detail about the causes of easier attacking to the microcomputers and more serious damages to the RTU by lightning strikes,and proposals certain effective rectification measurements and preventive solutions of lightening protection,which might be helpful for all power plants,substations and other enterprises.
