The GW8 series neutral point isolation switch is an AC 50Hz outdoor device used for connecting the neutral points of transformers under no-load conditions.
产品简介General
本隔离开关是由支柱绝缘子、绝缘瓷瓶和导电部分组成，在支柱绝缘子上部装有静触头及连接母线的连接板，在支柱绝缘子和绝缘瓷瓶座间有金属底座、操作拐臂、操作绝缘子。底座上装有闸刀，CS8人力操动机构通过连杆、操作绝缘子、拐臂与闸刀相连，也可配用CJ6电动机构。隔离开关采用拍合式结构，占地面积小；
隔离开关转动部分按免维护的要求设计。采用不锈钢轴销与无油自润滑轴承相配合结构；钢制件采用热镀锌，确保隔离开关操作灵活、轻便、
可靠、永不锈蚀。
GW8 outdoor high voltage disconnector is a single phase AC switching device for 50 to 60HZ high voltage.It is use for breaking transformerneutral point earthing when there is voltage but without load in the power system with the maximum voltage of 126kV.The product is divided two types:ordinary and anti-dirt (W)type.
The CS8 manual-operated device mechanism or CJ6 motor-operated device mechanism can be cooperated with the disconnector.
