| 综合国内外各种线路绝缘子防雷过电压保护器的优点，克服了现有的技术困难，具有保护间隙固定，防水，双层封闭的设计，放电值准确。安装方便，性能可靠、免维护等优点。 Combining the advantages of various line insulator lightning protection overvoltage protectors at home and abroad, it overcomes the existing technical difficulties. It has the design of fixed protection gap, waterproof, double-layer closure and accurate discharge value. Easy installation, reliable performance, maintenance-free advantages. 有足够的耐受操作过电压能力，有效的避免操作过电压作用动作，减轻限压元件，大大延长了限压元件的寿命。当线路受到雷击过电压，达到一定值时，保护器开始动作，从而防止因工频续流高温熔断绝缘线路，有效的避免了由于雷击过电压引起的短线、绝缘子闪络而造成的供电事故 。 It has enough ability to withstand switching overvoltage, effectively avoids the action of switching cangzhou.75ix.cnqinhuangdao.75ix.cnbaoding.71ix.cnxingtai.75ix.cn tongdiaob.71ix.com tongdiaod.71ix.comovervoltage, reduces the voltage limiting element, and greatly prolongs the life of the voltage limiting element. When the line is struck by lightning overvoltage and reaches a certain value, the protector starts to operate, so as to prevent the insulated line from fusing at high temperature due to power frequency continuous current, and effectively avoid the power supply accident caused by the flashover of short line and insulator caused by lightning overvoltage. |
