户外智能交流220KV隔离开关详细介绍

GW4-252(D)(W)
户外高压交流隔离开关

产品简介
□成套隔离开关由GW4-252(D)(W)型隔离开关本体、CS14G或CS17G型人力操动机构、传动附件等组成，也可配用CJ6型等电动机构。
□隔离开关属双柱水平开启式，各单级都由基座、支柱绝缘子、出线座及触头等部分组成，两支柱绝缘子相互平行地安装在基座两端的轴承上，且与基座垂直。主导电部分分别安装在两支绝缘子上方，随支柱绝缘子作约90°转动。
□隔离开关的轴承座设计成全密封结构，能防止灰尘、潮气、有害气体进入轴承座内部引起的卡阻现象；轴承座内部装有推力球轴承和向心球轴承，将隔离开关的重力及水平分力由这两种***轴承承担，使隔离开关长期运行后的操作力矩不会增加。各极两轴装配间通过连板、调节螺杆等连接传动。采用不锈钢轴销及自润滑轴套，润滑剂为高效二硫化钼锂基润滑脂。
□出线座中的紫铜编织带分别紧固在导电杆和接线板上，接线板供用户连接线路之用。
□中间触头部分的触指成对装配，靠弹簧使触指夹紧触指座和触头，以达到触头与触指间的磨损，提高使用寿命。
□隔离开关附有接地开关时，主导电回路与接地开关的联锁用基座上的扇形板与弧形板***，在主导电回路合闸时，接地开关不可合闸，接地开关合闸时，主导电回路不可合闸。
