概述
GW4-126型隔離開關(guān)是供高壓線路在無載荷情況下，進(jìn)行切換線路以及對(duì)被檢修的電器設(shè)備進(jìn)行電氣隔離的三極戶外高壓電器,該型隔離開關(guān)為雙柱式水平放置分合結(jié)構(gòu)，產(chǎn)品性能滿足GB1985《交流高壓隔離開關(guān)和接地開關(guān)》及IEC-129（1984）標(biāo)準(zhǔn)要求。
特點(diǎn)
1、改進(jìn)了軸承轉(zhuǎn)盤結(jié)構(gòu)，使軸承座實(shí)現(xiàn)了防水功能。且配有注油孔、調(diào)整螺釘，開關(guān)的整體性強(qiáng)且維護(hù)更加簡單、方便。
2、導(dǎo)電桿與觸頭之間、導(dǎo)電桿與觸指座之間均采用銅焊工藝，另外觸指與觸指座之間加裝軟連接，使產(chǎn)品的主回路電阻比采用螺釘連接的大幅減小，從而減少觸頭在運(yùn)行中的發(fā)熱問題。接地導(dǎo)桿采用導(dǎo)電性能優(yōu)良的鋁合金，觸頭部分采用紫銅件，導(dǎo)電桿與底座連接處及接地觸指座之間均加裝軟連接，因此接地回路的接地可靠性大大的增強(qiáng)。
3、主導(dǎo)電外露部分均采用紫銅鍍銀的表面處理工藝，鍍銀處理，表面光潔、美觀、抗腐蝕能力強(qiáng)、持久耐用。
4、改進(jìn)軸與孔配合方式：鐵與銅配合改為銅與銅配合或不銹鋼與銅配合，解決了在戶外長期使用出現(xiàn)的銹死現(xiàn)象。外露標(biāo)準(zhǔn)件采用不銹鋼；金屬件采用熱鍍鋅處理，開關(guān)的耐腐蝕能力更強(qiáng)。
5、大量采用精鑄件替代焊接件，減少焊接不牢等安全性問題。
6、接地刀閘可在施工現(xiàn)場(chǎng)左右互換，并改同軸聯(lián)動(dòng)方式單極聯(lián)動(dòng)，大大減輕施工現(xiàn)場(chǎng)安裝難度。

英文翻譯：
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 perbance 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 b 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 perbance 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 bl 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 bage way unipolar bage, greatly reduce the construction site install difficulty.
