AK-GDB组合式过电压保护器

AK-GDB组合式过电压保护器采用三相四柱组合式结构，适用于35KV及以下电力系统，是限制雷电过电压和操作过电压的一种新型保护电器。主要用于保护发电机、 变压器、开关、母线、电动机等电气设备的绝缘免受过电压的损害，它具有动作快、伏安特性平坦、残压低、稳定性好、组装维护方便等优点。对于相间和相地过电压都能起到有校的保护作用。

       过电压动作计数器是对产品工作状况进行实时及累计计数的装置。与图所示组合式过电压保护器配套使用，可以详细监视所保护线路的状况，预知事故前异常情况，达到分析异常动作原因，预防事故发生的作用。

       过电压在线监测仪是以嵌入式单片机为、数码管显示、面板安装，与图所示组合式过电压保护器配套使用，能够循环显示各相动作的日期、时间和次数，40组数据存储，能满足无人值守的要求。
