电动机保护用高压高分断能力高压限流熔断器适用于交流50HZ,额定电压3.6KV-10KV,额定电流400A(3.6KV),224A(7.2KV)及以下的电力系统中,作为高压电动机及其他电力设备的过载或短路保护用,也可与负荷开关,真空接触器等配合适用。
本高压熔断器符合国家GB15166.2标准和国际电工委IEC60282-1,IEC60644标准以及英国BS标准
XRNM系列高压熔断器采用插入式和母线式两种结构,具有安装体积小,接触可靠和更换方便的特点;撞击器并联于由纯银片制成的熔体,与经化学处理过的高纯度石英砂一起密封于熔管内;熔管采用耐高温的高强度氧化铝瓷制成,在线路发生故障时,熔体融化,在熔体出现电弧瞬间,撞击器的与熔体并联的高电阻金属丝立即熔断,撞击器迅速弹出,推动连锁电器触头,自动切换电路或发出熔断讯号。
