概述

GW4-126型隔离开关是供高压线路在无载荷情况下，进行切换线路以及对被检修的电器设备进行电气隔离的三极户外高压电器,该型隔离开关为双柱式水平放置分合结构，产品性能满足GB1985《交流高压隔离开关和接地开关》及IEC-129（1984）标准要求。

 
 
特点

1、改进了轴承转盘结构，使轴承座实现了防水功能。且配有注油孔、调整螺钉，开关的整体性强且维护更加简单、方便。
2、导电杆与触头之间、导电杆与触指座之间均采用铜焊工艺，另外触指与触指座之间加装软连接，使产品的主回路电阻比采用螺钉连接的大幅减小，从而减少触头在运行中的发热问题。接地导杆采用导电性能优良的铝合金，触头部分采用紫铜件，导电杆与底座连接处及接地触指座之间均加装软连接，因此接地回路的接地可靠性大大的增强。
3、主导电外露部分均采用紫铜镀银的表面处理工艺，镀银处理，表面光洁、美观、抗腐蚀能力强、持久耐用。
4、改进轴与孔配合方式：铁与铜配合改为铜与铜配合或不锈钢与铜配合，解决了在户外长期使用出现的锈死现象。外露标准件采用不锈钢；金属件采用热镀锌处理，开关的耐腐蚀能力更强。
5、大量采用精铸件替代焊接件，减少焊接不牢等安全性问题。
6、接地刀闸可在施工现场左右互换，并改同轴联动方式单极联动，大大减轻施工现场安装难度。

this

GW4-126 type isolating switch is for high voltage lines in no load, switch to be the maintenance of the lines and the electric equipment of electrical isolation three extremely high voltage outdoor appliances, this type of isolating switch for double column type level and placed points structure, the product performance meet GB1985 "ac high-pressure isolating switch and grounding switch" and IEC-129 (1984) the standard.

characteristics

1, improve the bearing turntable structure, so as to realize the bearing the waterproof function. And with a note oil hole, adjustment screws, switch the integrity of the strong and more simple and convenient maintenance.
2, conductive rod and contacts, between conductive rod and touch all use copper between a refers to the welding process, in addition to touch touch with a soft link between refers to the, make the product of main loop of resistance than the screw connection of a decrease, and reduce contacts in the operation of the fever. Grounding guide bar the conductive good performance of aluminum alloy, the contactor part adopts copper pieces, conductive rod and base joint and grounding contact between the cities are to soft connection, so grounded circuit grounding reliability big increase.
3, leading the exposed part all use copper plating silver surface treatment technology, silver processing, and the surface is bright and clean, beautiful, corrosion resistance is strong, durable.
4, and improvement of the shaft and hole with way: iron and copper copper and copper coordination with to or stainless steel and copper coordination, solved the long-term use of outdoor appear rust phenomenon. Exposed standard stainless steel; The metal hot dip galvanized processing, switch of corrosion ability stronger.
5, adopt a large number of casting replace welding, decrease the welding rickety safety problems, etc.
6, grounding in around the construction site breaker swap, and change coaxial linkage way unipolar linkage, greatly reduce the construction site install difficulty.
