| Product Overview | ||
| GCS low-voltage withdrawable switchgear is a withdrawable switchgear designed and developed by the Ministry of Electric Power Industry and the Ministry of Machinery Industry according to the requirements of the competent departments of the industry, the majority of power users and design units, which meets the national conditions, has high technical performance indicators, can adapt to the development needs of the power market and can compete with the existing imported products. It has been valued and affirmed by the manufacturing units and the power user departments. It is applicable to power plants, substations, petrochemical departments, industrial and mining enterprises, metallurgy and textile, high-rise buildings and other places with high degree of automation and requiring computer interface. As a low-voltage complete set of supporting device for power distribution, motor centralized control and reactive power compensation in the power generation and power supply system with three-phase AC frequency of 50Hz, rated working voltage of 400V and rated working current of 4000A and below. The protection grade reaches IP40. Comply with the national standard GB7251.1 Low-voltage Switchgear and Control Equipment - Part 1: Type Test and Partial Type Test Equipment,JB/T9661 Low-voltage withdrawable complete switchgear, international standard IEC439-1 Low-voltage complete switchgear and control equipment. |

| Structure Feature | ||
| The cabinet structure is composed of KS profiles (KB profiles can also be used). The standard module is 20mm. The cabinet body is electrostatic sprayed after acid cleaning and phosphating. Galvanizing and passivation treatment for internal partition and drawer. Each functional room is isolated from each other, and its compartment is divided into functional unit room, bus room and cable room. The function of each room is relatively independent, which can prevent touching live parts of adjacent functional units and limit the expansion of faults. | ||
| Functional Unit | ||
| The module of drawer floor height is 160mm, which is divided into five size series: 1/2 unit, 1/2 unit, 1/2 unit, 2 unit and 3 unit. The rated current of unit circuit is 400A and below. The drawer changes only in height, but its width and depth do not change. Drawers with the same functional unit have good interchangeability. Each Mcc cabinet can install up to 11 1-unit drawers or 22 1/2 drawers. The drawer unit is equipped with mechanical interlocking device, and the panel has obvious signs of opening, closing test, withdrawal and other positions. The design of this product improves the thermal capacity of the adapter and greatly reduces the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head and partition. The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the work of other units, so that the failure is limited to the minimum range. The drawer unit has a sufficient number of secondary plug-ins (32 pairs for unit 1 and above, 20 pairs for unit 1/2), which can meet the requirements of computer interface and automatic control circuit for the number of contacts. |
