概述  Outline

GCS 低壓抽出式成套開關(guān)設(shè)備（以下稱裝置）是原國家機(jī)械部、電力部聯(lián)合設(shè)計(jì)組根據(jù)行業(yè)主管部門、廣大電力用戶及設(shè)計(jì)單位的要求研制出的 符合國情、具有較高技術(shù)性能指標(biāo)、能夠適應(yīng)電力市場(chǎng)發(fā)展需要并可與現(xiàn)有引進(jìn)產(chǎn)品競(jìng)爭(zhēng)的低壓抽出式開關(guān)柜。

該裝置一九九六年七月在上海通過了 兩部聯(lián)合主持的鑒定，受到生產(chǎn)制造單位和電力使用部門的重視和肯定。 該裝置適用于發(fā)電廠、石油、化工、冶金、紡織、高層建筑等行業(yè)的配電系統(tǒng)。在大型發(fā)電廠、石化系統(tǒng)等自動(dòng)化程度高，要求與計(jì)算機(jī)接口的場(chǎng)所， 作為三相交流 50(60)Hz，額定工作電壓 380V，額定電流 4000A 及以下的發(fā)、供電系統(tǒng)中的配電、電動(dòng)機(jī)集中控制、無功功率補(bǔ)償使用的低壓套套配電裝置。 

該裝置符合 IEC439-1 和 GB7251.1 標(biāo)準(zhǔn)。

GCS LV with drawable switchgear(hereinafter referred to as device) is developed according to the requirements from industry competent department, numerous electric users and design unit by original state mechanical department, united design group of power department. It conforms to national conditions and with higher technical performance index, and adapts the demands for power market development and able to compete with available imported products. 

The device passed the authentication jointly presided by two departments in July 1996 in Shanghai. It obtains the recognition and affirmation from manufacturing unit and power consumer construction. The device is applicable to the distribution system of power station, petroleum, chemical engineering, metallurgy, weaving and tall building industriesetc. In the places with high automaticity and need computer to joint, such as large-scale power station and petrochemical industry system etc, it is the low voltage complete distribution device used in the generating and power supply system with three-phase AC50(60)Hz, rated working voltage 380V, rated current 4000A and below for distribution, motor central control and reactive power compensation. 

The device accords with standards IEC439-1 and GB7251.1.

主要特點(diǎn)   Main feature

1. 主構(gòu)架采用 8MF 型鋼，型鋼的二側(cè)面分別有模數(shù) 20mm 和 100mm 的 f9.2mm 安裝孔，內(nèi)部安裝靈活方便。 

2. 主構(gòu)架裝配形式設(shè)計(jì)為兩種，全組裝式結(jié)構(gòu)和部分（側(cè)框和橫梁）焊接式結(jié)構(gòu)，供用戶選擇。 

3. 裝置的各功能室相互隔離，其隔室分為功能單元室、母線室和電纜室。各室的作用相對(duì)獨(dú)立。 

4. 水平主母線采用柜后平置排列方式，以增強(qiáng)母線抗電動(dòng)力的能力，是使裝置的主電路具備高短路強(qiáng)度能力的基本措施。 

5. 電纜隔室的設(shè)計(jì)使電纜上下進(jìn)出均十分方便。

1. Main framework adopts 8MF bar steel. Both sides of bar steel is installed with φ9.2mm mounting hole with modulus 20mm and 100mm. Inner installation is flexible and easy. 

2. Two types of assembly form design for main framework, full assembly structure and partial (side frame and cross rail) welding structure for user selection. 

3. Each function compartment of device is separated mutually. The compartments are divided into function unit compartment, bus bar compartment and cable compartment. Each one hasrelative independent function. 

4. Horizontal bus bar adopts cabinet back level placed array pattern for enhancing the capacity of resisting electrodynamic force for bus bar. It is the basic measure for obtaining highshort circuitstrength capacity for main circuit. 

5. Cable compartment design makes cable outlet and inlet up and down convenient.

使用環(huán)境條件    Use environmental conditions

1. 周圍空氣溫度不高于 +40℃，不低于 -5℃，并且 24h 內(nèi)平均溫度不高于 +35℃。 

2. 相對(duì)濕度在高溫時(shí)不超過 50%，在較低溫度時(shí)允許有較高的相對(duì)濕度，例如 +20℃時(shí)為 90%，但應(yīng)考慮到溫度變化，有可能會(huì)偶然地產(chǎn)生適度 的凝露。 

3. 海拔高度不超過 2000 米。 

4. 安裝傾斜不超過 5°。 

5. 沒有粉塵，腐蝕性氣體和雨水浸襲的戶內(nèi)。

1. Ambient air temperature: -5℃ ~+40℃ and the average temperature should not exceed +35℃ in 24h. 

2. Relative humidity should not exceed 50% at max temperature. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually. 

3. Altitude above sea level should not exceed 2000M. 

4. Installation gradient not exceed 5° . 

5. Indoor without dust, corrosive gas and rain water attack.
