RN2型戶內(nèi)高壓限流熔斷器、熔斷特性
□RN2型戶內(nèi)高壓限流熔斷器，用于電壓互感器的保護(hù)，其斷流容量為1000MVA。在短路時以限制線路電流到最小值的方式進(jìn)行瞬 時開斷，1分鐘內(nèi)熔斷電流應(yīng)在0.6-1.8A范圍內(nèi)。
□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．
