LXK系列零序电流互感器

                             一.   概述(Description)

本型零序电流互感器为环氧树脂浇注户内型产品。适用于额定频率50Hz或60Hz、额定电压35kV及以下的小接地电流系统中作电缆接地保护用。与本系列电流互感器配套使用的继电器型号为DD-11/60和DD-1/60。

The zero current transformer of the type LXK is casting resin and indoor product. It is used for overdriven current protection in the electric non-useful-ground neutral system of rated frequency 50Hz or 60Hz and rated voltage 35kV. The types of the relay fitting with the transformers are DD-11/60 and DD-1/60.

二.  型号含义(Type designation)

三.  结构简介(Construction)

本型零序电流互感器为开合式。二次绕组及铁芯均浇注在聚脂树脂内。安装时可将互感器分为两半，中间窗孔供一次母线穿过，然后用螺栓拧紧。

The zero sequence current transformer is open-close type. The secondary windings and iron core are insulated by epoxy resin. Being installed make the product dimidiation, then make it coalition used bolt. The middle hole is used for busbar going through.

四.  技术参数(Technical data)

1. 该型零序互感器的一次主绝缘由电缆保证，产品仅考核二次绕组的绝缘性能。二次绕组对地能承受3 kV工频耐压。(Because the cable protects the primary main insulation, the insulation characteristics of secondary winding are only examined. The secondary winding can be able to withstand the power frequency test voltage of 3 kV to ground.) 

2. 零序电流互感器的灵敏度满足下表的要求。 (The sensitivity of the product shall meet the requirements listed in form)
