GW1-10[DDW]-630\~1250分体型/连体型户外高压隔离开关

Separate Type / Combined Type Outdoor High Voltage Isolator Switch

产品简介Product Introduction

GW1-10型户外高压隔离开关适用于装置在户外高压配电设备线路上，供线路在有电压，无负载时切断线路及转换线路之用。本产品是由三个单独的单极隔离开关组成的三相电器。每个单极隔离开关都具有相同的组成部分，如底座支柱绝缘子，前后静触头，闸刀及弧角等。

GW1-12G型户外高压隔离开关是针对原GW1开关存在的一系列问题，按现行的国家标准和国际标准改型设备而成的一种新型开关。开关本身带有接地闸刀，能有效地防止“带电挂地线和带地线合闸”等误操作，操作人员也不必再另挂接

地线。该产品其电气性能和机械性能优良，已全面达到国家标准GB1985及其第一号修订和国际电工标准IEC129、IEC694的要求，是现行10kV级户外隔离开关的更新换代产品。

GW1-12LT型户外高压隔离开关属双柱垂直开启式，配用的手动操作机构为CS8-5D防雨型，电动操作机构为CX-6型。本产品为三相共底架闸刀式开关，可分为底架、绝缘子及导电部分，底架由转轴及弯板和角钢焊成的框架组成，底架上

固定六个资绝缘子，每两个组成一极，转轴上装有三相操作绝缘子，用来操作三相的闸刀分、合闸运动，导电部分由触头闸刀和触座组成，用弹压紧。分闸时由操作拐臂带动转轴旋转，使操作绝缘子向上顶着闸刀使闻刀和触头分开，闸刀绕触座旋转，触头也在闸刀的带动下向上移动至分闸位置。合闸时由操作拐臂带动转轴旋转，使操作绝缘子拉着闸刀向下转动在和触头向遇后带动触头旋转，一起转至合闸位置。

The GW1-10 outdoor high-voltage isolator switch is suitable for installation on outdoor high-voltage distribution equipment lines, used to disconnect or switch lines under voltage but no load. This product consists of three individual single-pole isolator switches to form a three-phase device. Each single-pole isolator switch has the same components, such as base insulator posts, front and rear static contacts, blade switches, and arc horns. The GW1-12G outdoor high-voltage isolator switch is a new type of switch developed by modifying the original GW1 switch to address a series of issues. It is designed according to current national and international standards. The switch is equipped with a grounding blade switch, which effectively prevents misoperations like “connecting the ground line while energized”or“closing the switch while grounded." Operators no longer need to install additional grounding lines. This product has excellent electrical and mechanical performance, fully meeting the requirements of national standard GB1985 and its first revision, as well as international standards IEC 129 and IEC 694. It is an upgraded product for the existing 10kV outdoor isolator switch.

The GW1-12LToutdoor high-voltage isolator switch is a double-pole vertical-opening type. The manual operating mechanism is the CS8-5D rainproof model, and the electric operating mechanism is the CX-6 type. This product is a three-phase common base frame blade switch, which can be divided into the base frame, insulator, and conductive parts. The base frame is welded from a rotating shaft, bent plates, and angle steel to form a framework. Six porcelain insulators are fixed on the base frame, with two insulators forming one pole. Three-phase operating insulators are mounted on the rotating shaft to operate the blade switches' opening and closing movements. The conductive part consists of the contact blades and contact seats, which are pressed by springs. When opening, the operating arm drives the rotating shaft to rotate, causing the operating insulator to push the blade switch upward, separating the blade from the contact. The blade rotates around the contact seat, and the contact moves upward to the open position under the blade's action. When closing. the operating arm drives the rotating shaft to rotate, causing the operating insulatorto pull the blade switch downward. The contact moves with the blade switch and rotates together until reaching the closed position.

Outdoor Double-Pole Horizontally Opening High Voltage Isolator Switch

产品简介 Product Introduction

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。
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。
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;

触指弹簧改为外置式，以避免弹簧分流

增加磁锁板，提高动热稳定性能。

转动部分配有自润滑套，无需润滑脂。

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。

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。

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。

◆The entire product undergoes hot-dip galvanizing for corrosion protection. For areas that require rotational movement, stainless steel materials are used, as hot-dip galvanizing cannot guarantee the necessary tolerance. Fasteners smaller than M8 are made of stainless steel, while the rest are hot-dip galvanized.

The conductive part features a copper tube flexible connection, with the middle contact being a “handshake” self-powered type contact. The spring-loaded pressure type is without current flow. The isolator switch has only one contact point in the center, with the rest fixed by flexible connections.

◆A new contact structure is used, with one end of the contact piece fixed to the contact seat. The contact pressure is generated by the deformation of the contact piece and spring, making the sliding contact at the end of the contact fixed, thus improving conductivity reliability.

◆The contact spring is changed to an external type to avoid current diversion.

A magnetic lock plate is added to improve dynamic thermal stability.

◆The rotating part is equipped with a self-lubricating sleeve, eliminating the need for grease.

The main terminal is a flat plate type. For current ratings of630A,the conductive part is tin-plated; for current ratings of 1250A-4000A, the conductive part is silver-plated. The upper and lower caps of the ceramic parts are hot-dip galvanized for rust prevention, with different creepage distances for ceramic parts available based on local pollution levels. During manufacturing, tolerances are strictly controlled, and the creepage distance is designed to be higher than the nominal standard value.

◆The switch uses pillar insulators with high strength and density for stability and reliability. The high-strength ceramic material formula reduces the product's strength variability, increasing tensile strength. The structural design allows for a large strength reserve to ensure stable and reliable operation during use.

结构简介 Structure Overview

◆35kV成套隔离开关由GW4-40.5(D)(W)型隔离开关本体、CS11或CS8-6D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。110KV成套隔离开关由GW4-126(D)(W)型隔离开关本体、CS14G人力操动机构、传动附件等组成，也可配用CJ6型等电动机构。

该隔离开关属双柱水平开启式隔离开关。制成单极型式，当三极同步使用时，极间用连接杆连接起来。各单级都由基座支柱绝缘子、出线座及触头等部分组成，两支柱绝缘瓷瓶相互平行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，随支柱绝缘瓷瓶作约90°转动。

隔离开关的每个轴承座内装有轴装配，两轴装配间通过连板、调节螺杆等连接传动。

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。配用CS8-6D时隔离开关与接地开关连锁由机构上的连锁板实现

The 35kV complete isolator switch consists of the GW4-40.5(D)(W) isolator body, CS11 or CS8-6D manual operating mechanism, transmission accessories, and can alsobe equipped with electric actuators such as CJ6. The 110kV complete isolator switch consists of the GW4-126(D)(W)isolator body, CS14G manual operating mechanism, transmission accessories, and can also be equipped with electric actuators such as CJ6.

This isolator switch is a double-pillar horizontal-opening type. It is made in a single-pole design, and when the three poles are used synchronously, they are connected by a connecting rod. Each single pole consists of a base support insulator, outgoing seat, and contacts. The two pillar insulator porcelain bottles are mounted parallel to each other at both ends of the base' s axial bearing and are perpendicular to the base. The main conductive parts are mounted above the two pillar insulator porcelain bottles and rotate approximately 90° with the insulator porcelain bottles.

Each bearing seat of the isolator contains an axle assembly, with the two axle assemblies connected by a connecting plate, adjusting screw, and other components to transmit movement. The copper braided flexible connection in the outgoing seat is fastened to both the conductive rod and the terminal plate, which is used for user connection to the circuit. The contact fingers of the middle contact section are assembled in pairs and adopt a self-powered contact design with a turning-in type to reduce wear between the contacts and contact fingers during switching, thus extending service life.

When the isolator switch is equipped with a grounding switch, the interlocking between the main conductive circuit and the grounding switch is ensured by the sector plate and arc-shaped plate on the base. This ensures that the grounding switch cannot be closed when the main conductive circuit is closed, and the main conductive circuit cannot be closed when the grounding switch is closed. When the CS8-6D is used, the interlocking of the isolator switch and grounding switch is achieved through the interlocking plate on the mechanism.

产品特点 Product Features

隔离开关采用双柱中开、触头转入式结构，具有自动清洁触头的能力，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。

◆The isolating switch uses a dual-column middle-opening and rotating contact structure, which has the ability to automatically clean the contacts, improving contact reliability.

◆The contact fingers are made from high-strength, high-conductivity, and high-elasticity materials. They rely on the spring force of the contact fingers to clamp the contacts, preventing the decrease in clamping force, increased contact resistance, and the resulting heat buildup caused by corrosion and heat-annealing of springs.

◆ The rotating parts of the isolating switch are designed for maintenance-free operation. The rotating seat is designed with a sealed structure, preventing moisture, dust, and harmful gases from entering. This ensures that the bearings and molybdenum disulfide lithium-based grease always operate in a good environment, with bearings never rusting and grease never leaking or drying out. As a result, the operating torque of the isolating switch will not increase even after long-term operation.

◆The structure uses stainless steel pins paired with oil-free self-lubricatingbearings. Steel components are hot-dip galvanized to ensure smooth, lightweight, and reliable operation of the isolating switch, which will never corrode.

The isolation switch features a double-pole V-shaped horizontal opening design. Each pole consists of a base, pillar insulator, outgoing terminal, and contact parts.

◆The two pillar insulators are installed at a 50° angle and are mounted on the bearing at both ends of the base, perpendicular to the base. The main conductive components are installed above the pillar insulators and rotate approximately 90° with the pillar insulators.

The soft copper braided connections in the outgoing terminal are securely fastened to the conductive rods and terminal boards, with the terminal boards provided for user connections. The central contact parts have paired contact fingers and use selflocking contact fingers, which are of the sliding type to reduce wear between the contacts and fingers during the switching process, thus enhancing service life.

When the isolation switch is equipped with a ground switch, the interlock between the main electrical circuit and the ground switch is ensured by the sector and arc plates on the base. This interlock prevents the ground switch from closing when the main electrical circuit is closed, and prevents the main electrical circuit from closing when the ground switchis closed.

The entire switch is treated with a hot-dip galvanizing process for corrosion protection. For parts that require rotational movement, stainless steel is generally used, as hot-dip galvanizing cannot guarantee the proper fit. Fasteners below M8 are made of stainless steel, while the rest are made of hot-dip galvanizedmaterials.

The conductive parts feature soft copper tube connections, and the central contact uses a "handshake" type self-locking contact finger. The spring-external pressure design ensures no current flow through the switch when disengaged. The isolation switch has only one contact point in the middle, with the rest of the connections secured by soft connections.

◆A new contact structure is employed, fixing one end of the contact blade to the contact base. The contact pressure is generated by the deformation of the contact blade and the spring,which converts the sliding contact at the end of the contact finger into a fixed contact, improving conductivity reliability.

The contact finger spring is now external to avoid spring shunting.

A magnetic lock plate is added to enhance dynamic thermal stability.

◆The rotating parts are equipped with self-lubricating bushings, eliminating the need for grease.

◆The main terminal is of a flat-type design. For a current rating of 630A, the conductive components are tin-plated; for current ratings between 1250A and 4000A, the conductive components are silver-plated.

◆The upper and lower caps of the ceramic insulators are hot-dip galvanized for rust protection, and different creepage distance insulators can be selected depending on the pollution level of the operating area. During manufacturing, the creepage distance is designed higher than the nominal value to ensure compliance with the positive tolerance control.

The switch uses pillar insulators with high strength and density, providing stable and reliable performance. The formulation employs high-strength porcelain materials to reduce product strength dispersion and enhance tensile strength. The structural design allows for significant strength margin, ensuring stable and reliable operation of the product.

◆The isolating switch adopts a double-pole center-opening design with a "tum-in" type contact structure, which automatically cleans the contacts and improves contact reliability.

The contact fingers are made from high-strength, high-conductivity, and high-elasticity materials. The contact pressure is maintained by the spring force of the contact fingers, avoiding the reduction of clamping force, increased contact resistance, and the vicious cycle of overheating caused by corrosion and thermal annealing of the spring.

The rotating parts of the isolating switch are designed for maintenance-free operation. The rotating seat is sealed, preventing moisture, dust, and harmful gases from entering. This ensures that the bearings and the MoS lithium-based lubricating grease always operate in an optimal environment, preventing rust and grease loss, and maintaining a steady lubrication state. The operating torque does not increase after prolonged use. The design uses stainless steel pins and self-lubricating bearings without oil. Steel components are hot-dip galvanized to ensure smooth, lightweight, reliable, and rust-free operation.

产品简介 Product Introduction

本产品为三相线路系统单相使用，结构简单、经济、使用方便。

本产品为单断口垂直打开式结构，单极隔离开关支柱绝缘子安装在各自底架上，主要由底座、支柱绝缘子、主导电回路部分、自锁装置等组成。采用闸刀式结构分合闸达到切断和闭合线路。每相闸刀由两片导电刀片组成，刀片两侧外装有压缩弹簧调节弹簧的高度可以得到开关闸刀所需要的接触压力。开关分合闸时用绝缘钩棒操作机构部分，闸刀有自锁装置。

This product is designed for single-phase use in three-phase line systems. It features a simple structure, cost-effectiveness, and ease of use.

The product adopts a single-break vertical opening structure. The single-pole isolating switch's support insulatoris mounted on its base frame. It primarily consists of a base, support insulator, main electrical circuit, and self-locking device. The switch operates by a knife-blade mechanism for circuit opening and closing. Each phase' s knife blade is composed of two conductive blades, with compressed springs installed on both sides to adjust the spring height and provide the required contact pressure for the switch. The switch is operated using an insulated hook stick, and the knife blades are equipped with a self-locking device.

工作原理 Working Principle

隔离开关分合时用绝缘钩棒操作，绝缘钩棒扣住隔离开关锁钩，拉动锁钩向分闸方向，解开自锁装置后带动与之相连的寻电板旋转实现分闸动作，合闸时由绝缘钩棒顶住隔离开关锁钩带动转轴旋转，使之相连的导电板转动至合闸位置，此时自锁装置将隔离开关锁定在合闸位置。本型隔离开关可安装于支柱、墙壁、天花板、横架或金属架上，也可以立装、斜装，但安装位置应使触刀打开时趋向下方。

The isolating switch is operated by an insulated hook stick. The hook stick engages with the isolating switch lock hook and pulls it in the direction of opening. After releasing the self-locking mechanism, the conductive plate connected to the lock hook rotates, achieving the opening action. During closing, the insulated hook stick pushes against the lock hook, driving the shaft to rotate and moving the connected conductive plate to the closed position. At this point, the self-locking mechanism locks the isolating switch in the closed position.

This type ofisolating switch can be installed on supports, walls, ceilings, crossbars, or metal frames. It can be installed vertically or at an angle, but the installation position should be such that the knife blade opens downward.
