GCSLow-voltage Withdrawable Switchgear
GCS type low-voltage withdrawable switchgear (hereinafter referred to as the device) is designed and developed by the two joint design teams according to the requirements of the competent department of the industry, the majority of power users and design units. It meets the national conditions, has high technical performance indicators, and can adapt to the development of the power market. Low-voltage withdrawable switchgear that requires and can compete with existing imported products. The device has been widely used by power users. The device is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems, etc., where automation is high and the interface with the computer is required, the three-phase AC frequency is 50 (60) Hz, the rated working voltage is 380 (400, 600) V, and the rated current is 4000 A and below. Low-voltage power distribution equipment used for power distribution, motor centralized control, and reactive power compensation in power and power supply systems. The design of the unit complies with the following standards: IEC439-1 Low-voltage switchgear and control equipment
Model and meaning
In order to improve the thermal stability of the busbar and improve the temperature rise of the contact surface, the device is all made of TMY-T2 series hard copper row, and the connection part of the copper row must be pressed and tinned. It is recommended to use full-length tin-tin. Full length silver plated copper busbars are also available.
The horizontal busbar of the device is selected as follows:
Neutral grounding bus
(high x thick) + (bottom x thick)
(PE+N) specifications are as follows
2. The functional rooms of the device are strictly separated, and the compartments are mainly divided into functional unit rooms, busbar rooms and cable rooms, and the functions of each unit are relatively independent.
