GCS type low-voltage drawer switch cabinet is a product developed by integrating the advantages of other low-voltage products. It is suitable for power plants, petrochemical, metallurgy, telecommunications, light industry, textiles, high-rise buildings and other civil, industrial and mining enterprises. The distribution system is used in large power plants, petrochemical, telecommunications systems and other places with high degree of automation and computer interface, as a low-voltage distribution device for centralized control and reactive power compensation of distribution motors in power generation and power supply systems.

Use environment and scene

1. For indoor use, the altitude of the use point shall not exceed 2000m.

2. The ambient air temperature is not higher than 40 degrees and not lower than minus 5 degrees. And the average temperature within 24 hours shall not be higher than 35 degrees. When exceeding, the operation shall be reduced according to the actual situation.

3. The relative high temperature of the surrounding air is +40 degrees and not more than 50%, and a larger relative temperature is allowed at a lower temperature; if +20 degrees is 90%, consideration should be given to the influence of accidental condensation 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 and conform to the (GBJ232-2) standard.

5, the device should be installed in the absence of severe vibration and impact and not enough to use electrical components should not be corroded.

GCS type low voltage drawer type switch cabinet product features

1, improve the heat capacity of the adapter, greatly reduce the temperature rise due to the adapter to the connector, cable head, spacer plate to bring additional temperature rise;

2. The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the work of other units, so that the failure is limited to a minimum range;

3. The flat arrangement of busbars makes the device have good dynamic and thermal stability and can withstand the impact of 80/176kA short-circuit current;

4, GCS cabinet single cabinet circuit number up to 22 times, fully consider the large single capacity power generation, petrochemical systems and other industries automatic electric door (machine) group needs;

5. The connection between the device and the external cable is completed in the cable compartment, and the cable can enter and exit up and down. The current transformer is installed in the cable compartment, which makes installation and maintenance convenient: 6. For the same power distribution system, the short-circuit current can be limited through current limiting reactor matching, the bus voltage can be stabilized at a certain value, and the requirements for short-circuit strength of components can be partially reduced;

7. The drawer unit has a sufficient number of secondary connectors (32 pairs for unit 1 and above and 20 pairs for 1/2 unit), which can meet the requirements of computer interface and automatic control circuit for the number of contacts.
