LJ-Φ75、110

■额定频率50Hz或60Hz
Rated frequency 50Hz or 60Hz
■用于额定电压35kV及以下的小接地电流系统中供电缆接地保护用
They are used for overdriven current protection in the electric non-useful-ground neutral system up to rated votlage 35kV.
■与本型电流互感器配套使用的继电器型号为DL-11/0.2
The type of the relay fitting with the transformers is DL-11/0.2
■本型零序电流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3kV。
Because the cable protects the primary main insulation,so,the insulation characteristics of secondary winding are only examined. The secondary winding can be able to withstand the power frequency test voltage of 3kV to ground.
