GCS low-voltage switchgear is a type of draw-out switchgear, which is used for three-phase ac frequency of 50Hz, rated working voltage of 400V(690V), rated current of 4000A and below. It is used in power supply system as power, distribution, centralized control of motor and capacitor compensation. The specific equipment information of this product is as follows:

GCS low-voltage switchgear implementation standard

GCS low voltage switchgear conforms to GB7251. 1-1997 low-voltage switchgear and control equipment and JB/ t9661-1999 low-voltage draw-out switchgear.

Ii. Structural features of GCS low-voltage switchgear

1, the framework USES 8 mf type opening sections, installed on the main frame modulus is E = 20 mm and 100 mm Φ 9. 2mm mounting hole makes frame assembly flexible and convenient;

2. The function rooms of the switch cabinet are isolated from each other. The compartments are divided into function unit rooms, bus rooms and cable rooms. The functions of each chamber are relatively independent;

3. The horizontal bus shall be arranged in the horizontal cabinet to enhance the resistance of the bus to electric power, which is the basic measure to enable the main circuit to have high short-circuit strength;

4. The design of cable compartment makes it convenient to enter and exit the cable from the top to the bottom.

5. The modulus of drawer height is 160mm. The drawer changes only in the height dimension changes, its width, the depth dimension does not change. The drawer of same function unit has good interchangeability. Rated current of unit circuit 400A and below;

6. The drawer panel is clearly marked with the position of dividing, closing, testing and drawing. The drawer unit is equipped with mechanical interlocking device. The drawer unit is the main body, and it can be mixed and used arbitrarily.

7. The protection level of cabinet body is IP30IP40, which can also be selected according to user needs.

Three, GCS low-voltage switchgear advantages

GCS low-voltage switchgear has high technical performance indexes, can meet the needs of the power market development, and can compete with the existing introduced products. According to the principle of safety, economy, reasonableness and reliability, the new type of low-voltage draw-out switch cabinet is designed, which also has the characteristics of high breaking and connecting capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicability of series, novel structure and high protection level.

Iv. Application of GCS low-voltage switchgear

GCS low-voltage switchgear is widely used in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other places, also can be used in large power plants, petrochemical systems and other places with high degree of automation, requiring computer interface.
