LXK

■本系列电流互感器适用于户内、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相电缆接地保护用。也可与继电器配套使用。
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 frequency 50Hz or 60Hz and rated votlage 35kV. The transformers are fitting with the relay too.
■安装时可将互感器分为两半,然后合并为一体,用螺栓拧紧。可以在不停电状态下进行安装。
Being installed, at first, make the product dimidiation. Then make it coalition used bolt. Can be loaded at hot-line condition.
■本型互感器一次主绝缘由电缆保证,产品仅考核二次绕组的绝缘性能,二次绕组对地耐压为35kV。
Because the cable protects the primary main insulation, so, the insulation characteristics of secondary winding are only examined. The secondary winding can be ablet withstand the power freguency test voltage of 3kV to ground.
