GCS Low voltage draw out switch cabinet

Main purpose and scope of application
GCS low-voltage withdrawable switchgear is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries. In large-scale power plants, petrochemical systems and other places that require high degree of automation and computer interface, as a three-phase AC frequency of 50/60Hz, rated working voltage of 380V/400V/660V, rated current of 4000A and below power generation and motor centralized control , Reactive power compensation and other low-voltage complete sets of power distribution devices.
This product complies with: National Standard GB/T7251.12-2013.

Model and meaning

Working conditions
1. The ambient air temperature should not be higher than +40℃, and the average temperature within 24 hours should not be higher than +35℃. If it exceeds, the operation should be reduced according to the actual situation;
2. For indoor use, the altitude of the point of use should not exceed 2000m ;
3, changes in the ambient air relative humidity may occasionally produce condensation;
4, mounting means and the vertical gradient of not more than 5%, and the entire group listed relatively flat cabinet;
5, should be installed in severe vibration and Impact and places where the electrical components are not sufficiently corroded;
6. When the user has special requirements, it can be resolved through consultation with our factory.

Product features
1. The main frame is made of 8MF open section steel, which is cold-formed from 2.5mm cold-rolled plate. The triangular surface of the section steel has mounting holes with modulus of 20mm and 100mm, and 9.2mm. It has high strength and is easy to mold. Features of the installation.
2. The drawer type is divided into four size series: 1/2 unit, 1 unit, 2 unit, and 3 unit. The rated current of the loop is 400A and below.
3. Flexible assembly, compact structure, strong versatility, good safety performance, compressed space, and convenient assembly.
4. Increase the heat capacity of the adapter, and greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the plug-in, cable head, and spacer plate.
5. The functional units and compartments are clear and reliable. The failure of one unit does not affect the work of other units, and the failure is limited to the minimum range.
6. The horizontal arrangement of the busbar makes the device have good dynamic and thermal stability, and can withstand the impact of 80/176kA short-circuit current.
7. The number of circuits in a single MCC cabinet is as many as 22, which fully considers the needs of large-scale single-unit capacity power plants, petrochemical systems and other industries for automated electric door (machine) groups.
8. The connection between the device and the external cable is completed in the cable room, and the cable can go in and out up and down. The zero-sequence current transformer is placed in the cable compartment, which makes installation and maintenance easy.
9. The same power distribution system can limit the short-circuit current through the matching of current-limiting reactors, stabilize the bus voltage at a certain value, and partially reduce the requirements for the short-circuit strength of the components.
10. The drawer unit has a sufficient number of secondary connectors (32 pairs for 1 unit and above, 20 pairs for 1/2 unit) to meet the requirements of the number of docking points for computer interfaces and automatic control loops.
