探索有线电视机房布线雷击的防范

Exploration of CATV Engine Room Wiring Lightning Prevention

广电在激烈的竞争中必须不断提升网络运营的安全性,作为网络传输骨干节点的有线电视机房安全显得尤为重要,广电部门在建设有线电视机房时虽然把防雷工程作为一项重要内容,但一般只考虑机房的接地、建筑防雷及在供电线路和信号线上安装防雷器,而对机房布线的安全性与合理性考虑不周。以天台县有线电视机房布线遭受雷害的实际案例来对机房布线进行理论分析与计算,总结出机房布线防雷的理论依据与建设经验。

Radio and television in the increasingly fierce competition convergence in the competition, must continuously upgrade of CATV network safe operation, as the network backbone node cable television machine room security is very important. Radio and television departments in the construction of cable television ma chine room construction although the lightning protection project of CATV machine room as .an important con tent of the construction, but generally consider only the room grounding, building lightning protection and pow er supply line and a signal line installation of lightning protection device, and the computer room layout of the safety and rationality of illconsidered. According to my county cable television machine room wiring from the actual case to lightning computer room layout theory analysis and calculation, explored in the engine room wir ing lightning protection has some theoretical basis and construction experiences.
