产品简介General

本产品为双柱水平断口中间开启式，可以一侧或两侧附装接地开关。90°传动的隔离开关采用CS17型人力操作机构进行三级联动操作；180传动的隔离开关采用CJ6型电动机操作机构进行三级联动操作；接地开关采用CS17G人力操动机构三级联动操作。

本系列隔离开关属双柱V形水平开启式，各单级都由基座、支柱绝缘子、出线座及触头等部分组成，形成50°夹角的两个支座、支柱绝缘子两支柱绝缘瓷瓶相互夹角地安装在基座两端地轴承上，且与基座垂直。主导电部分分别安装在两支柱绝缘瓷瓶上方，随支柱绝缘瓶作约90°转动。出线座中的紫铜编织带软连接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，采用自力型触指，其形式为转入式，以减少分、合闸时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连锁用基座上的扇形板与弧形板保证，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。

GW5 series outdoor high voltage disconnector is a three phase AC switching device for 50 to 60HZ high voltage.It is used for breaking thecircuit when there is voltage but without load in the power system with the maximum voltage of 40.5kV.72.5kV or 126kV.

According to the usage,the product is divided into ordinary,anti-dirt and special(Z)types.The special type is further divided into three types,which are mounted in a side,up-side-down or inclining way,so the mounting is flexible.

The earthed switching part of the product has two ways of earthing,i.e.single or double earthing.The earthing switch has a structure of typeI ortype II and the electric parameters of the type II earthing switch has the same short-circuit withstand ability as the disconnector switch.The product is provided with a manual or motor operating device and an electromagnetism lock can also be fitted to prevent from wrongoperation.The exposed parts are all made of stainless steel or processed with aluminum alloy processing technology or hot-zinc-plating techno-logy to ensure operation with no corrosion for a long period of time,and further ensure the flexibility and reliability of the product,satisfy therequirements in the different areas.

产品特点

隔离开关采用双柱中开、触头转入式结构，具有自清洁触头的能力，提高了接触可靠性；

触指采用高强度、高导电率、高弹性的新型材料制造。依靠触指自身的弹力夹紧触头，避免了目前因弹簧锈蚀，发热退火而引起的触头夹紧力降低接触电阻增加，触头发热加剧的恶性循环。

隔离开关转动部分按免维护的要求设计。转动座设计成密封结构，水汽尘埃、有害气体无法进入，使轴承、二硫化钼锂基润滑脂永远工作在良好的环境中，轴承永不生锈，润滑脂无法流失，永不干涸，使隔离开关长期运行后的操作力矩不会增加。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。

Isolating switch with double column,contact into open type structure,has the ability of self cleaning contact,improve the contact reliability;Finger made of new material with high strength,high conductivity,high elastic.Relying on the elastic contact finger clamping itself,to avoidthe spring corrosion,contact clamping fever caused by annealing

Force to reduce the contact resistance increases,the contact heat intensified the vicious spiral.

The rotating part according to the design requirements of the isolating switch maintenance free.The rotating seat designed seal structure,moisture,dust and harmful gas can not enter,bearing,molybdenum disulfide lithium base grease will never work in

A good environment,bearing,never rust,grease can not be lost,never dry up,the isolation switch operating torque will increase after longterm operation.Stainless steel shaft and oil-free self-lubricating bearing

With the structure of steel by hot dip galvanizing,ensure the isolation switch operation is flexible,portable and reliable,never rust.

完善化隔离开关特点说明

1.全部采用热镀锌工艺防腐处理，热镀锌不能保证配合要求转动的部位一般均采用不锈钢材料，紧固件M8以下采用不锈钢，其余均采用热镀锌。

2.导电部分铜管软连接型，中间触头为“握手“式自力型触指，弹簧外压式无电流通过，隔离开关只有中间一个接触点，其余均用软连接固定联接。

a.采用新的触头结构，将触片一端与触座固定，靠触片变形及弹簧产生接触压力，使触指末端的滑动接触改为固定接触，提高导电可靠性；

b.触指弹簧改为外置式，以避免弹簧分流；

c.增加磁锁板，提高动热稳定性能。

3.转动部分配有自润滑套，无需润滑脂。

4.主接线端子为平板型。电流等级为630A时，导电部件表面镀锡；电流等级为1250A-4000A时，导电部件表面镀银。

5.瓷件上、下帽采用热镀锌防锈，并根据使地区污秽等级的不同可选用不同爬距的瓷件；在生产制造过程中按正差控制，爬电距离设计时将公称值较标准值设计的高。

6.开关用支柱绝缘子强度密度大、稳定可靠、配方采用高强度瓷料制造，减少了产品强度的分散性，增加了产品的抗拉强度，结构设计时已对产品已有较大的强度预留度，使产品在运行中保证稳定可靠。

1.all the hot dip galvanizing process embalmed,can not ensure that they meet the requirements of galvanized rotating parts are generallymade of stainless steel,stainless steel fasteners M8 below,the rest are hot dip galvanized.

2.conductive parts brass soft-linked,among contacts for a "handshake"type of self-type finger spring no current through the external pressure,isolation switch only the middle one contact point,the rest were fixed connection with a soft connection.

a.new contact structure,contacts and contact base end fixed contacts by deformation and contact pressure spring produce,so that the end ofthe finger sliding contact to the fixed contact,to improve the conductivity reliability;

b.finger spring to external,in order to avoid spring diversion;

c.to increase the magnetic lock plate,improve dynamic thermal stability.

3.Turn the department assigned to self-lubricating sleeve,no grease.

4.The main terminals for flat type.When the current level is 630A,tin-plated conductive member;current rating of 1250A-4000A,the silveredsurface of the conductive member.

5.porcelain pieces,hot dip galvanized under the cap and make the region according to different levels of contamination can choose differentpieces of porcelain from the climb;the nominal value in the manufacturing process,according to the positive control,a creepage distancedesign higher than the standard value of the design.

6.The switch post insulator strength density,stable and reliable,high-strength porcelain formulation manufactured,reducing the strength of theproduct dispersion,increases the tensile strength of the product,the product structure has been designed to use a pre-existing greater strengthstay and make the products to ensure stable and reliable in operation.
