Features of GCS low voltage switchgear

1. Increase the heat capacity of the adapter, and greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the connectors, cable heads, and spacers.

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.

3. The horizontal arrangement of the bus bar makes the device have good dynamic and thermal stability, and can withstand the impact of 80/176kA short-circuit current.

4. The number of circuits in a single MCC cabinet is as many as 22, fully considering the needs of large single-unit capacity power generation, petrochemical systems and other industries for automated electric door (machine) groups.

5. The connection between the device and the external cable is completed in the cable compartment, 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.

6. 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.

7. The drawer unit has a sufficient number of secondary plugs (32 pairs for 1 unit and above, 20 pairs for 1/2 unit). It can meet the requirements of the number of connection points of the computer interface and the automatic control loop.

Install and use

After the product arrives at the receiving location, first check whether the packaging is intact.

For products that are not installed immediately, they should be placed in an appropriate place according to normal use conditions and temporary storage regulations for electrical equipment, and stored properly.

1. The product installation should be carried out according to the installation diagram. The base channel steel and the bolts when the bolts are used for fixing are provided by the user. When the main busbar is connected, if the surface is uneven due to transportation, storage, etc., it needs to be leveled and then connected and tightened.

2. When the device is installed alone or in a row, the verticality and the deviation of the unevenness of the cabinet surface and the gap of the cabinet shall meet the following regulations.
