Product overview

GCS type low-voltage draw-out switchgear is a low-voltage draw-out switchgear designed and developed by two joint designs according to the requirements of the industry authorities, the majority of power users and design units, which conforms to the national conditions, has high technical performance indicators, can adapt to the development needs of the power market and can compete with the current introduction of products. The device has been widely used by power users.

The device is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with high degree of automation and computer interface, 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 power supply systems with three-phase AC frequency of 50(60)Hz, rated working voltage of 380(400, 660)V and rated current of 4000A and below. The design of the device conforms to the standards of IEC439-1 low-voltage switchgear and control equipment, GB7251 low-voltage switchgear assembly and JB/T9661-1999 low-voltage draw-out switchgear assembly.

Model and meaning

Use of environmental conditions

◆ 1. The ambient air temperature is not higher than 40 ℃, not lower than -5 ℃. The average temperature within 24 hours shall not be higher than 35 ℃. If it exceeds the limit, it shall be operated according to the actual situation;

◆ 2. For indoor use, the altitude of the use place shall not exceed 2000m;

◆ 3. The relative humidity of the surrounding air shall not exceed 50% when the maximum temperature is +40 ℃, and a larger relative humidity is allowed when the temperature is lower, such as 90% when the temperature is +20 ℃. It should be considered that the influence of frost may occur accidentally due to temperature changes;

◆ 4. When the device is installed, the inclination with the vertical plane shall not exceed 5%, and the whole group of cabinets shall be relatively flat (in line with GBJ232-82 standards);

◆ 5, the device should be installed in the absence of severe vibration and impact and not enough to make electrical components should not be corroded places;

◆ 6, if there are special requirements, indicate in advance.
