油田集输站安全监控系统防雷分析与设计

Study on lightning proof technology of oil field security surveillance and control system

大气过电压对油田集输站视频及参数监控等电子设备是非常有害的,所以必须对其进行防御。本文通过对雷击种类及其破坏机理的分析,掌握了雷击的基本避雷原理,据此对直击雷和感应雷分别采用避雷针和避雷器、屏蔽接地的避雷方法来进行防护,并对这些方法进行了分析与设计。利用本文的避雷方法对油田集输站的监控系统的雷击防护进行了设计,取得了不错的防雷效果。实践证明本文的避雷措施是行之有效的。

Lightning strike is menace fo it is necessary. The avoid lighting prin lightning strike in this paper, which is the basic for adopting lightning rod and arrester and shield grounding to defend direct lighting and induction lighting. These methods are used to design the Lightningproof system of oil field transfer station surveillance and control system. The practice achieved good effect and proved these methods available.
