校园网络系统防雷

校园网络系统耐雷击过电压的能力极差,一旦遭雷击就会造成网络部分功能丧失甚至全部瘫痪。雷电主要通过电源电路和各种网络信号线路及地电位反击等危害校园网络系统,因此防止雷电危害应采取综合防护措施。结合某校园网络系统工程实例,进行雷击风险评估后得出合理的防护等级,然后从校园网络整体出发,采用多种防护措施,给出校园网具体的防雷电及过电压实施方案,从而降低校园网络雷击受损概率。

Lightning Prevention of Campus Network System

Campus network system is the core system and information platform of the college, and its security ne eds more and more attention. The ability of lightning over-voltage tolerance is very low, even leads to system failure. The lightning harms the campus network system via power supply circuit, network signal lines and ground electricity cou nter. Taking a campus network system construction case as an example, its lightning prevention level after evaluating the lightening risk was evaluated, a nd then the specific lightning prevention measures for the college were given to redu ce the probability of lightning damage to the campus network system.
