摘　　要：在水利行业,布置于野外的电子系统日益增多,受到雷电干扰引起的故障和损毁设备的事件频发。分析了雷电干扰的特点、干扰侵入野外系统的主要途径,以及侵入后的传播方式,从接地线、接地、滤波器的设置及等电位连接等方面提出野外电子系统防止雷电干扰的注意点。In water resources industry, more and more electric equipments are installed in fields, which occur frequently accidents of equipment breakdown caused by lightning interference. This article deals with analysis on characteristics of lightning interference, main ways of interference intruding into field electronic equipment, and its transmission path on electronic equipment after intrusion. At last, some points that should be brought to attention in lightning protection ＆ anti-interference of field electronic equipment are given from aspects of grounding line, grounding, filter configuration and electric potential..
