本系列电流互感器适用于户肉 ， 额定频率50Hz或60Hz额定电压35kV及以下的小接地电流系统中供三棺电缆接地保护用， 也可与继电器配套使用。
安装时可将互感器分为两半， 然后合并为一体， 用抱箍抱紧卡住。可以在不停电状态下进行安装。
These series of current transformers are used indoor. They are used for three plases overdriven current protection in the electric not-useful-ground neutral system up to rated freguency 50Hz or 60Hz and rated voltage 35kV. The transformers are fitting with the relay too.
Being installed , at first, make the product dimidiation. Then make it coalition use bolt. Can be loaded at hot-line condition.
