概述:

GCS低压抽出式开关柜适用于三相交流频率为50Hz,额定工作电压为400V(690V),额定电流为4000A及以下的发、供电系统中,作为动力、配电和电动机集中控制、电容补偿之用。广泛应用于发电厂、石油、化工、冶金、纺织、高层建筑等场所,本产品符合IEC60439-1、GB7251.1、JB/T9661等标准。本柜体采用了新的制造工艺并各功能单元采用模块化设计,单元组合灵活方便,可实现并替代目前市场上的GCS的石油方案及功能。

主要性能与特点:

1. 框架采用C型材,主构架上安装模数为E=25mm的φ5.3mm的安装孔,使得框架组装灵活方便;

2. 开关柜的各功能室相互隔离,其隔室分为功能单元室、母线室和电缆室,各室的作用相对独立;

3. 水平母线采用柜后平置式排列方式,以增强母线抗电动力的能力,是使主电路具备高短路强度能力的基本措施;

4. 电缆隔室的设计使电缆上、下进出均十分方便;

5. 抽屉高度为150mm、200mm、300mm、400mm、500mm、600mm,其宽度、深度尺寸不变;相同功能单元的抽屉具有良好的互换性。单元回路额定电流400A及以下;

6. 抽屉面板具有分、合、试验、抽出等位置的明显标志。抽屉单元设有机械联锁装置。以抽屉单元为主体,同时抽屉单元和固定单元可以混合组合,任意使用;

7. 柜体的防护等级为IP30-IP40;

8. 材质可选为冷轧板、镀锌板、敷铝锌板制作。

Overview :

GCS low voltage switchgear cubicle is suitable for system with AC 50Hz,rated working voltage up to 660V,current up to 4000A,and applicable for power generation,transmission,distribution,charge-over and consumption equipment control. It conforms of relevant standards such as IEC60439-1,GB7251.1 and JB/T9661 and are widely used in power plant,metallurgical factory,petroleum industry,chemical industry,textile industry and high-rise buildings.Designed with advanced manufacturing technique and a modularized and flexible structure,GCS(Ⅱ)can replace all traditional GCS solutions in the market.

Main performance and features :

1. The frame is adopted with C profiles. The mounting holes in φ5.3mm with module E=25mm on the main framework enable its assembly flexible and convenient;

2. The switchgear is divided into function unit compartment,busbar compartment and cable compartment with each compartment isolated and function relatively independent;

3. The horizontal busbar is placed flat at the back as to strengthen its capability against electromotive power ,which is a basic measure to make the main circuit have strong short circuit capability;

4. The design of cable compartment facilitates easy access of cable;

5. The drawer height is 150mm、200mm、300mm、400mm、500mm、600mm,same in which and depth.The drawers of same function units have great inter change ability. The rated current of unit loop is up to 400A;

6. The drawer panel is marked with obvious signs for positions as breaking,making,testing and drawing out. The drawers unit is provided with mechanical interlock device. Usually,drawer units are the main options,but they can be mounted together with fixed units in one cubicle for random use;

7. The degree of protection of the enclosure is IP30-IP40;

8. Material optional with cold rolled steel,galvanized steel or Aluminum-zinc coated steel.
