開關(guān)母線室 LBS-Busbar chamber

●不銹鋼密封氣箱（除熔斷器外），構(gòu)成了開關(guān)母線室。

The LBS-busbar chamber is formed by Stainless steel gas sealed tank besides fuses.

三相負(fù)荷開關(guān)作為一個(gè)整體部件調(diào)試完后裝入氣箱內(nèi)，開關(guān)結(jié)構(gòu)為旋轉(zhuǎn)式三工位，兼?zhèn)涓綦x和接地功能。開關(guān)靜觸頭上裝有金屬柵欄，且呈曲線型，增強(qiáng)滅弧時(shí)去游離效果。

Three-phase LBS is fixed in gas sealed tank as a compiete component after assembly and adjustment. The structure of LBS is of rotary type three positions one ,it is with disconnection and isolation function.There are matel arc-barries on top of static contacts arrayed in curve to enhance the dis-extrication effect during are-extinguishing.

●為優(yōu)化氣箱內(nèi)的電場分布，主母線設(shè)計(jì)為帶R5圓角的矩形銅排，環(huán)網(wǎng)回路母線和變壓器回路母線分別為Φ20mm和Φ10mm的銅棒，對(duì)可能引起放電的部位，如母線連接及固定處，均裝設(shè)了金屬屏蔽罩，用以均勻電場，提高絕緣強(qiáng)度。

For optimize the electric field inside tank , the rectangle shape main busbars are designed to be with R5 fillet,the loop busbar of ring net and transformer adopt copper rods with diameter of Φ20mm and Φ10mm separately, the metal shield covers are used in somewhtere the point or marginal discharge may cause just like the connections and the fixed of busbar, for equalizing the electric field therefore rising up the insulation strength

操作機(jī)構(gòu)室 Operating mechanism chamber

The operating mechanism which is of disk spring type with high assembly preesion and stability and with long service life and easy operation is divided into two types, the single spring using for ring net circuit (incomer unit) and double spring using for transformer circuit (outgoing unit).

熔斷器室 Fuse chamber

●熔斷器室（熔斷器密封倉）位于柜體中部，置于充滿SF6氣體的氣箱中。 熔斷器密封倉由采用APG工藝澆注的環(huán)氧樹脂絕緣筒及上導(dǎo)電極和下導(dǎo)電極（端蓋）組成。前門上有熔斷器動(dòng)作指示器，方便觀察和維護(hù)。用操作手柄擰開可方便更換熔斷器。

Fuse chamber (fuse silo), consisting of epoxy resin insulation barrels casted by APG technology and upper and nether conductors (cover), is located in middle of cubicle and built in SF6 gas filled tank. There are melt indicators of fuse on the front door for easy checking and maintaining. The operating handle can be used for replacing the fuse body after unscrewing the covers.

電纜室 Cable chamber

●柜內(nèi)電纜安裝空間寬裕，電纜連接高度約600mm，每單元的電纜室之間用敷鋁鋅板隔開，便于維護(hù)和檢修。剩余的大部分空間可裝電流互感器及其它控制保護(hù)器件。

The cable chamber of cubicle is big enough for fitting cable, the connection height of cable can reach over 600mm, except the cable, the rest space can be use to fit the CT or other control and protection components if any. The cable chamber of each unit is isolated by Aluzine steel sheet to convenience for checking or maintaining.

●電纜的連接采用預(yù)制式電纜插接件，插接件可選用屏蔽型、非屏蔽型，也可加裝避雷器。

The prefabrictad cable inserters, either shield type one or non-shield type one, are adopted for cable connections. The arresters can also be fitted here too.

●對(duì)于雙電纜進(jìn)線并加裝避雷器，必須采用加深的電纜室蓋板，電纜室的底部裝有接地母排。

If double incoming cables and adding arresters, the deepening cable chamber cover should ba used. There is earthing busbars locating in the bottom of cable chamber.

斷路器本體 Vacuum circuit breaker

●單個(gè)傳動(dòng)密封口，減少漏氣幾率。

There is only one sealling driving to be used, it reduce the gas leakage probability.

●改變傳統(tǒng)的絕緣方式，不用絕緣拉桿，傳動(dòng)軸采用強(qiáng)度高，絕緣性能好的材料制造。

The driving shaft of vacuum circuit breaker is made of excellent insulation material with high strength, it is no longer a traditional insulation pulling rod.
