Jiuzhou Electric GCS-type drawer Low-voltage switchgear Is based on the power authority, power users, the requirements of the design department, to meet the growing electricity market of the capacity increase, computer interface, power centralized control, easy installation and maintenance, reduce incident handling time required, in line with safety, economy, and reasonable and reliable approach in the design of the new drawer-type low-voltage switchgear. The product has a breaking, connected to high-capacity, electric program flexible combination of convenience, the series of practical, innovative design, high level protection features can be used as low pressure switch cabinet drawer generation product to use. The product conforms to China's national conditions, with high technical performance, relatively low cost, to meet the development needs of the electricity market, and may introduce products with the existing competition in the domestic market, the drawer-type low-voltage switchgear.
GCS type low voltage switch cabinet drawer type suitable for power plants, Oil , Chemical industry , Textile, building and other industry distribution system substation. In large power plants, petrochemical systems, high degree of automation, requirements and computer interface places, as the three-phase, frequency of 50 (60) Hz, rated voltage of 380V (400V), (660V), rated current of 6300A and the following generation, power distribution systems, motor centralized control, reactive power compensation of power conversion, distribution and control the use of low voltage power distribution equipment.
Features Structure Switching equipment used 8MF steel main frame. Architecture using assembly and part of the welding of the structure and main frame are installed on the modulus E = 20,100 mm of 9.2mm hole, so that is very convenient for internal installation. Switchgear enclosure has sufficient strength to withstand short circuit product produced by short-time withstand current and peak withstand current shocks. At the same time will not Equipment The lifting, transportation, installation, etc. of equipment performance.
Switch cabinet equipment layout safe, reliable, reasonable and consistent product performance requirements, cabinet with sufficient space to facilitate cable head production, connection and maintenance and overhaul.
Switchgear provides mobile handling lifting rings to the switchgear in the transport and handling during installation.
Switchgear room separate from the function, functional unit rooms, bus room, cable rooms, each unit function of the relative independence.
Switchgear enclosure protection rating of IP30 (or IP40).
Cable compartment there are two width sizes (240mm and 440mm) available for selection, installation and external cables connected to the cable compartment completed, the cable can be up and down and out, depending on the number of cable, cross section, and users easy installation and maintenance request.
Cabinet with a drawer-based, both withdrawable and fixed type, can be mixed assembly, arbitrarily chosen.
Drawer A) a drawer-storey modulus 160mm, divided 1 / 2 units, 1 unit, 1.5 unit, 2 unit, 3 unit size series of five, single-circuit rated current 400A and below;
B) change drawer size changes only in the height, width, depth, dimension change;
C) Each MCC cabinets can be installed up to 11 or 22 of a drawer unit 1 / 2 unit of the drawer;
D) drawer unit into the outlet by the current size of the number of different pieces of film of the same size structure of the connector, usually a connector 200A;
E) between the drawer and an electrical adapter cable chamber pieces by the adapter to bear: 1 / 2 room unit drawer and cable adapter between the structure of the adapter with back pieces; one, two, three units room drawer and cable adapter between the structure of the adapter with rod parts.
