Gcs Low Voltage Power Distribution Switchgear - Withdrawable

Overview

Type GCS low-voltage withdrawable switchgear is two joint design according to the department in charge of industry, the majority of power users and design units developed in accordance with the requirements of design conditions, with high technical performance indicators, to meet the need of electric power market development and can compete with the introduction of existing product low voltage draw-out switch cabinet, the device has been widely use electricity users.

Applications

The device is suitable for the power plant, petroleum, chemical, metallurgical, textile, power distribution system of high-rise building and other industries. In large power plants, petrochemical system, such as high degree of automation, and computer interface, as the frequency of the three-phase ac 50 Hz , rated voltage of 400 V, (690V) , rated current is 4000 A and below the hair, power supply system of power distribution, centralized control of the motor, reactive power compensation using low-voltage power distribution equipment. The design of the device meets the following criteria it 1 GB7251 "low-voltage complete switch and control equipment" "low-voltage complete switch equipment" ZBK36001 ", "low voltage draw-out switchgear

Operating environment:

1. Ambient temperature: -25°C~45°C; Maximum temperature difference ≤ 25ºC

2. Altitude: ≤2000Meter;

3. Relative humidity: Average value of daily relative humidity ≤ 95% Average value of monthly relative humidity ≤ 90%

4. Anti-earthquake capacity: Earthquake intensity ≤ 8 class

5. Be kept away from drastic shake and impulse, fire, chemical corrosion and explosion. 6. Used place: indoors

Structure features:

1. The unit 8 mf steel is used in the main frame, frame using both assembly and parts of welding structure. Are installed on the main frame modulus E = 20 mm/100mm  holes.  

2. The device is strictly separate each function room, the main compartment is divided into functional unit rooms, bus room, cable room, the function of each unit are relatively independent.  

3. Feeder tank and motor control cabinet is equipped with a dedicated cable compartment, functional unit room and indoor cable connection through the transfer or transfer copper platoon, can not only improve the using reliability of cable, and made great user for cable installation and maintenance. Cable compartment has two width dimension  available, depending on the number of cable for easy installation and maintenance, cross section, and users request.    

4. Consider the use of dry type transformer normal sexual safety and economy of oil-immersed transformer, device can be convenient and dry type transformer form a set of columns, can also convenient and oil-immersed transformer low-voltage busbar connection.  

5. To the drawer as the main body, at the same time draw out type and fixed type, can mix combination, arbitrary selection.
