GCS low voltage draw out switch cabinet this device is suitable for power distribution system of power plant, petroleum, chemical industry, metallurgy, textile, high-rise building and other industries.
 
In large power plants, petrochemical systems and other places with high degree of automation and computer interface requirements, it is used as a complete set of low-voltage power distribution device with three-phase AC frequency of 50 (60) Hz, rated working voltage of 380V (400V) and 660V, rated current of 4000A and below.

The main frame adopts 8MF open section steel, which is formed by cold bending of 2.5mm cold rolled plate. There are mounting holes with modulus of 20mm, 100mm and 9.2mm on the three sides of the section steel, which has high strength and is convenient for modular installation;
 
 
 
The drawer type is divided into four size series: 1 / 2 unit, 1 unit, 2 unit and 3 unit. The rated current of the circuit is 400A and below;
 
 
 
■ flexible assembly, compact structure, strong versatility, good safety performance, compressed site and convenient assembly;
 
 
 
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;
 
 
 
■ clear and reliable communication between functional units and compartments, without affecting the work of other units due to the fault of one unit, so that the fault is limited to the minimum range;
 
 
 
The flat arrangement of bus bar makes the device have good dynamic and thermal stability and can withstand the impact of 80 / 176ka short-circuit current;
 
 
 
The number of circuits in a single MCC cabinet is up to 22, which fully considers the needs of automatic door (machine) groups in large single capacity power plants, petrochemical systems and other industries;
 
 
 
The connection between the device and the external cable is completed in the cable room, and the cable can go up and down. The zero sequence current transformer is installed in the cable compartment, which is convenient for installation and maintenance;
 
 
 
In the same power distribution system, the current can be limited by matching the current limiting reactor to stabilize the bus voltage at a certain value, and the requirement for short circuit strength of components can be partially reduced;
 
 
 
The drawer unit has enough secondary connectors (2 pairs for more than 1 unit level and 20 pairs for 1 / 2 unit), which can meet the requirements of computer interface and automatic control hoist for the number of contacts.
