通信机房浪涌过电压的保护

对通信机房浪涌过电压的保护，是保护通信线路、设备的重要技术手段，是通信网建设及运行管理工作的重要组成部分。根据三级防护原则，文章分别叙述了通信机房各级防护工作中必不可少的防护措施，以及机房内用电设备过电压防护的三级措施，这些防护措施适用于各种类型的通信机房，可根据机房各自规模及功能的不同，采用全部或采用部分措施。

Surge over-voltage protection in the telecom-center

Surge over-voltage protection in the telecom-center, is important technical means to protect communication circuitry and equipment ,and important part of communication network construction and management. On the basis of the three-level protection principle, necessary protection measures in all-level protection practice and three-level measures of over-voltage protection of the electrical equipment in the telecom-center are discussed respectively. These protection measures can be used in different kinds of telecom-centers. So one telecom-center can take all or part of them according to their circumstances.
