GGD1 Low-voltage Fixed Switchgear

GCSLow-voltage Withdrawable Switchgear

OverviewGCS 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.Product Standards

The design of the unit complies with the following standards: IEC439-1 Low-voltage switchgear and control equipment

GB7251 low voltage switchgear

JB 1T9661-1999 low voltage withdrawable switchgear

Model and meaning

The main technical parameters

bus bar

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.

Horizontal bus

The horizontal busbar is placed in the busbar compartment at the rear of the cabinet. 3150A and above are double-layer layout, 2500A and below are single-layer layout, each phase consists of 4 or 2 busbars, which greatly improves the short-circuit strength of the busbar.

The horizontal busbar of the device is selected as follows:

Vertical bus

The vertical busbar for the chest of drawers uses an "L" shaped hard copper tin busbar.

Neutral grounding bus

L-shaped busbar specifications

Hard copper row

(high x thick) + (bottom x thick)

Through horizontal neutral ground (PEN) or ground + neutral

(50x 5)+(30x5)

(PE+N) specifications are as follows

Rated current 1000A
