③ 摘要
近年来，变电站的通信、通信系统、继电保护系统、后台管理模块经常发生过电压损毁事件，究其原因主要是其相关系统和弱电产品过电压防护水平较弱，甚至根本没有过电压防范技术措施，其后果对电网的安全运行带来了较大负面影响。随着综合自动化系统和通信自动化系统等二次弱电系统在变电站的广泛应用，这类电子系统(设备)元器件的集成度愈来愈高，信息存储量愈来愈大，速度和精度不断提高，而工作电压只有几伏，信息电流仅为微安级，因而对外界干扰极其敏感，特别对雷电等电磁脉冲和过电压的耐受能力很低。当雷电等过电压和伴随的电磁场达到某一阀值时，轻则引起系统失灵，重则导致设备或其元器件永久性损坏。尽管雷电直击电子系统(设备)的可能性不大，但是雷击附近大地、建筑物、交流供电线路和空中雷云放电时直接形成的，或者由于静电感应及电磁感应形成的冲击过电压，都有可能通过与之相连的电力线路、信号线路或接地系统，通过各种接口，以传导、耦合、辐射等形式，侵入电子系统(设备)并酿成严重的干扰或事故。因此，加强和改进电子系统(设备)的防护，尽量减小其遭受雷电等冲击干扰损害造成的直接损失和间接损失，已成为当今亟待解决的问题
In recent years, the substation communications, communications systems, protection systems, background management module frequent over-voltage damage, the main reason for this is weak and its related systems products over-voltage protection level is weak, or no guard against over-voltage Technical measures, the consequences for the safe operation of power grids bring about a greater negative impact.
