产品概述 Product overview

GCS 型低压抽出式开关柜，适用于发电厂、石油、化工、冶金、纺织、高层建筑等行业的配电系统。在大型发电厂、石化系统等自动化程度高，要求与计算机接口的场所，作为三相交流频率为 50(60)Hz、额定工作电压为 400V、660V，额定电流为 5000A 及以下的发、供电系统中的配电、电动机集中控制、无功功率补偿使用的低压成套配电装置。 

装置的设计符合下列标准：IEC439-1《低压成套开关和控制设备》GB7251《低压成套开关设备》。 

GCS type low-voltage draw-out switchgear is suitable for power distribution systems in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with high degree of automation and computer interface requirements, it is used as a low-voltage complete power distribution device for power distribution, centralized motor control and reactive power compensation in power generation and supply systems with three-phase AC frequency of 50(60)Hz, rated working voltages of 400V and 660V and rated current of 5000A or less. 

The design of the device conforms to the following standards: IEC439-1 《Low Voltage Complete Switchgear and Control Equipment》 GB7251 《Low Voltage Complete Switchgear》.

正常使用环境 Normal operating environment

◇ 周围空气温度不高于 +40℃， 不低于 -5℃ , 24 小时内平均温度不得高于 +35℃。超过时，需根据实际情况降容运行； 

◇ 户内使用，使用地点的海拔高度不得超过 2000m； 

◇ 周围空气相对湿度在最高温度为 +40℃时不超过 50％，在较低温度时允许有较大的相对湿度，如 +20℃时为 90％，应考虑到由于温度的变化可能会偶然产生凝露的影响； 

◇ 装置安装时与垂直面的倾斜度不超过 5°， 且整组柜列相对平整 ( 符合 GBJ232-82 标准 )； 

◇ 装置应安装在无剧烈震动和冲击以及不足以使电器元件受到不应有腐蚀的场所 ; 

◇ 用户有特别要求时，可以与制造厂协商解决。 

◇ Ambient air temperature shall not be higher than +40℃ , not lower than-5℃ , and the average temperature within 24 hours shall not be higher than 

+35℃ . In case of exceeding, the capacity shall be reduced according to the actual situation. 

◇ For indoor use, the altitude of the place of use shall not exceed 2000 m; 

◇ The relative humidity of the ambient air shall not exceed 50% at the highest temperature of +40℃ , and relatively high relative humidity is allowed at lower temperature, such as 90% at +20℃ , which shall be considered Due to changes in temperature, condensation may occasionally occur. 

◇ When the device is installed, the inclination to the vertical plane shall not exceed 5, and the whole set of cabinet columns shall be relatively flat (in line with GBJ232-82 standard); 

◇ The device shall be installed in a place free from severe vibration and impact and insufficient to expose electrical components to corrosion. 

◇ When users have special requirements, they can negotiate with the manufacturer.
