摘　　要：现代通讯设备向着大容量、高集成度的方向不断发展,微型电子电路在设备中被广泛使用,而微型电子电路对电压、电流、温湿度等条件的要求是非常苛刻的,电压的波动、环境的干扰都有可能造成通讯设备异常甚至产生故障。大自然是严酷的,尤其是在雷电等自然现象面前,"柔弱"的通讯设备很容易受到伤害,如何减少和避免这种伤害,涉及到电源、接地、防雷等众多学科,文章从雷电入侵电子通信设备入手,主要阐述高山台站防雷的一些基本原理,并从实践的角度探讨雷击防护的有效方法。The modem communication equipment is developed to the direction of large capacity and high level of integration. The miniature electronic circuit in the equipment is widely used, and the requirement of tiny electronic circuit is very rigorous to the conditions of voltage, current, the temperature and humidity. The voltage fluctuations, environment of interference may cause abnormal or even failure for the communications equipment. From the lightning invasion to the electronic communications equipment, this article mainly expounds the basic principles of lightning protection in the mountain stations, and from the point of view of practice, it explores the effective method to lightning protection.
