概述Description

本型放电线圈为环氧树脂真空浇注单相户内半封闭型产晶，其适用于额定频率50Hz、额定电压10kV及以下的电力系统中。与高压并联电容器组并联连接，当电容器组与系统开后，以在5s内将电容器组上的剩余电压降至安全电压。在正常运行时，二次绕组可以做电压指示，用户如有要求时，亦可带剩余电压绕组，起到继电保护作用。

This type of discharge coil is epoxy resin vacuum casting single phase 、idoor semienclosed type product. It is applicable to be used for the power system with high voltage parallel connection capacitor group. When capacitor group cuts off from the system, It can take only five second to reduce the residual voltage of the capacitor group to safe voltage. When operating is normal , the secondary winding is used as voltage indicator. If users have special requirements,it can have relay protection action with residual voltage winding.

结构简介Construction

  本型放电线圈采用铁心外露半浇注式结构。铁心为硅钢片叠装而成。其体积小、重量轻、空载小、抗过电压能力强，使用安装方便，免维护，是替代油浸式放电线圈的理想产晶。

This discharge coil adopts iron core semi-casting type structure. The iron core is ma de up of high grads silliconsteel sheet. The product is small volume, light weight , little load and strong ability of resistance to over voltage ,convenient use and installation and needn't maintenance. It is new product for superseding the oil-immersed type discharge coi l.
