FDZ2/11/√3-3.4-1W放电线圈
- 本型放电线圈系单相户内、户外装置，环氧树脂绝缘的全封闭产品与高压并联电容器组并联连接，当电容器组与系统断开后，能在5s 内将电容器组上的剩余电压由 2 Un 降至50V 以下。在正常运行时，二次绕组可以作电压指示，剩余绕组接成开口三角，当电容器极间局部发生故障时，会产生零序电压，驱动继电保护装置。本型放电线圈特点为体积小，重量轻、无局部放电、抗过电压能力强、空载损耗小，空载电流小、防污能力强、使用安装方便、免维护，是替代油浸式放电线圈的*产品。
- This type of discharge coil is single-phase,cast resin insulated used indoors or outdoors connected with high voltage parallel connection capacitor group.When the capacitor group is cut off from the system,it can take only five second to reduce the residual voltage of the capacitor group from 2Un to below 50V.When operating normal,the secondary winding is used as voltage indicator and the residual winding is connected as split triangle.If the pole of capacitor partial breaks down,it would bring the zero sequence voltage to drive relay protection gear.The product is small,light,little partial discharge energy and high resistance to over voltge,It is a new product for superseding the oil type discharge coil．
