Scope of application:
The GCS type low-voltage withdrawable switchgear (hereinafter referred to as "switchgear") is a low-voltage withdrawable switchgear designed and developed by our company to meet the requirements of design units and power users. It meets the national conditions, has high technical performance indicators, can adapt to the development needs of the power market, and can compete with existing imported products. This product is currently widely used by power users.
Switchgear is suitable for power distribution systems in industries such as power plants, petroleum, chemical, metallurgical, textile, and high-rise buildings. In places with high automation levels such as large power plants and petrochemical systems that require computer interfaces, this low-voltage complete distribution device is used for distribution, centralized control of electric motors, and reactive power compensation in power generation and supply systems with a three-phase AC frequency of 50 (60) Hz, rated operating voltage of 380V (400V), (660), and rated current of 6300A or below. The basic form of switchgear (see Figure 1).
This product complies with the standards of GB7251 "Low Voltage Switchgear and Control Equipment", JB/T9661 "Low Voltage Shaft Out Switchgear", and EC60349 "Low Voltage Switchgear and Control Equipment".
Model and its meaning:
Normal usage conditions:
1. Surrounding air temperature: -15℃～+40℃, with a daily average temperature not exceeding+35 ℃. If it exceeds this temperature, the operation should be reduced according to the actual situation.
2. Altitude: not exceeding 2500m
3. Relative humidity: When the maximum temperature is+40 ℃, it should not exceed 50%. At lower temperatures, a larger relative humidity is allowed, such as 90% at+20℃. The influence of condensation due to temperature changes should be considered.
4. The installation inclination should not exceed 5 degrees, and the entire cabinet row should be relatively flat (in accordance with GBJ232-82 standard).
5. Switchgear should be installed in places where there is no severe vibration or impact, and where electrical components are not subjected to undue corrosion.
Note: When users have special requirements, they can negotiate with our company to resolve them.
