General info
Type GCS low-voltage withdrawable type switchgear is a blend of the
other advantages of low voltage products and the development of
advanced products, applicable to power plants, petrochemical
industry, metallurgy, telecommunications, light industry, textile,
high-rise buildings and other civil and industrial and mining
enterprises of power distribution system, in large power plants,
petrochemical, telecommunication system, etc. A high degree of
automation, and computer interface, as the motor
centralized-control hair, power supply system of power
distribution, low-voltage distribution of reactive power
compensation device.
Drawing
Structural features:
1.Framework using 8 mf type opening sections, installed on the main
frame modulus is E = 20 mm and 100 mm Φ 9.2 mm of mounting holes,
making flexible frame assembly.
2.The function rooms of the switch cabinet are isolated from each
other, and the compartments are divided into functional unit rooms,
bus rooms and cable rooms.The function of each chamber is
relatively independent.
3.The horizontal busbar adopts the way of horizontal arrangement
behind the cabinet to enhance the ability of the busbar to resist
electric power.
4.The design of the cable compartment makes it very convenient to
go in and out of the cable.
5.The module of drawer height is 160mm.Drawer changes change on
height dimension only, its width, depth dimension is
changeless.Drawers of the same functional unit have good
interchangeability.Rated current of unit loop 400A and below.
6.Drawer panel with division, close, test, pull out the obvious
mark of the position.The drawer unit is provided with a mechanical
interlock.Drawer unit as the main body, at the same time with draw
- out and fixed, can be mixed combination, arbitrary use.
7.The protection grade of cabinet body is IP30 IP40, still can
choose according to user need.
