发电厂信息系统的防雷保护

Lightning Protection of Power Plant Information System

首先就信息系统设备屡遭雷害的情况提出了防雷的问题,结合实例对雷害途径及特点进行分析,得出因地而异的雷害原因结论。提出信息系统防雷是个系统工程,需采取综合防护措施,但可根据实际需要选择应用,最后对接地网和电缆屏蔽方式问题进行了讨论,提出了选择性意见。

First it puts forward the problem of lighting protection which information system equipments is repeatedly lightning disturbanced, and analyzes the path and the characteris-ticses about lightning disturbanced through some examples. Then it comes to a conclusion that the cause of lightning disturbanced in different places. Putting forward that the information system lighting protection is a system engineering which need to take synthesize protection measure, or choose application according to the demand. Finally, it discuss the problem about earthing system and the way of shield of cable, puts forward selectivity opinion.
