污水处理厂自动控制系统防雷分析

摘要

针对污水处理厂易受雷击侵害的状况，根据雷电侵入的途径，分析了污水处理厂自控系统防雷隐患。通过对防雷设计中隔离、疏导、电源保护等几方面的论述,探讨如何建立自控系统综合防雷体系，以提高污水处理厂自控系统防雷能力。%Aim at the situation of sewage treatment plant that is susceptible by lightning, this paper analyzes the route of lightning invasion, and the hidden dangers of lightning protection for automation control system. From multiple aspects, such as isolation, diver- sion and power protection, the integrated lightning protection measures are discussed emphatically, which can improve the lightning protection capacity of the automated system in sewage treatment plant.
