Product Overview

CGS type low-voltage withdrawable complete switchgear is suitable for distribution systems in industries such as power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings, and other industries. In large power plants, petrochemical systems, and other places with high automation levels, requirements and calculations, as well as machine core interfaces, it is used for distribution in power generationand supply systems with a three-phase AC rate of 50 (60) Hz, a rated working voltage of 380V (400V), (660V), and a rated power output of 4000A and below. The motor is centrally controlled, Reactive power compensation enables the low-voltage complete distribution device of Yang.

Model and meaning

Functions and Features

Increase the thermal capacity of the adapter and significantly reduce the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head, and partition board;

The separation between functional units and compartments is clear and reliable, and the failure of one unit does not affect the operation of other units, limiting the fault to a small range;

The horizontal arrangement of the busbar ensures good dynamic and thermal stability of the device, and can withstand the impact of 80/176kA short-circuit current;

The number of circuits in a single GCS cabinet can reach up to 22, fully considering the needs of automation electric door (machine) groups in industries such as large single unit capacity power generation and petrochemical systems

The connection between the device and external cables is completed in the cable compartment, and the cables can enter and exit up and down. The current transformer is installed in the cable compartment, making installation and maintenance convenient;

In the same power distribution system, the short-circuit current can be matched with a current limiting reactor to stabilize the bus voltage at a certain value, and it can also partially reduce the requirements for the short-circuit strength of components;

The drawer unit has a sufficient number of secondary plugins (32 pairs for 1 unit and above, and 20 pairs for 1/2 unit), which can meet the requirements for the number of contacts in computer interfaces and automatic control circuits.
