煤矿通信系统接地的要求及防雷措施

The Request on Communication Facility System Earth and Measures on Anti-thunder in Coal Mine

煤矿通信系统由于其自身的特殊性及外部环境的复杂性,且出于安全生产的需要,必须采取适当的保护措施以避免因过电压及其所产生的过电流对设备和人员造成的危害,合理的系统接地是其能够安全稳定可靠的工作运转的保障。本文重点介绍"整体统筹、综合治理、多重保护"的防范原则,力争使通信系统获得更高的可靠性,把各种干扰的影响降低到最低点。

Because of Coal Mine of communication own specificity and the complexity of the external environment and the need for safe production. Therefore, because must take the suitable protective measures to avoid the electric current which the overvohage and produces the harm which to the transmission line, the communication facility and the peizonncl creates. The system is reasonably safe and stable and reliable operation of the protection work.This article introduced with emphasis.＂whole overall plan, comprehensive program of public order, multiple protections＂ the guard principle, argues vigorously cquses the communieations system to obtain a higher reliability, reduces the bottom each kind of disturbance＇s influence.
