RN2型户内高压限流熔断器、熔断特性
□RN2型户内高压限流熔断器,用于电压互感器的保护,其断流容量为1000MVA。在短路时以限制线路电流到最小值的方式进行瞬 时开断,1分钟内熔断电流应在0.6-1.8A范围内。
□The product is used in overload or short-circuit protection for instrument transformer.At the time of holding up by restrain circuit current way to get minimum from carry on instantaneous to turn on and break,it should be within the range of 0.6-1.8A to fuse the electric current in one minute.
