Product Details

产品概述:
HC-BHQ-X12.7/36型线路绝缘子防雷过电压保护器是把限流元件与线路绝缘子并联,通过限流元件、串联球间隙的间隙配合,即在限流元件的上方安装可调节动间隙球和绝缘子上方的绝缘导线上安装静间隙球,当线路受到雷击过电压时,感应过电压尚未达到绝缘子闪路时保护器球间隙开始放电,之后将雷电流导向氧化锌限流元件,雷电流氧化锌限流元件释放,而工频续流则被氧化锌限流元件截断,达到“避雷”的目的,从而防止架空绝缘线路雷击断线及绝缘子闪路或击穿,保护架空绝缘线路,避免发生断线、绝缘子闪络或击穿而造成大面积停电和售电量的损失或引起重大的人身伤害事故及由此引发的巨额经济赔偿。
