1, the series combination of the basic framework for structure assembly. Structural framework of all connected through the screw fastening into the basic framework, and then need to add doors, baffle, partition, drawer, mounting brackets and electrical components, such as buses and spare parts, assembled into a complete switchgear.
1.1 framework for the use of special steel, steel plates using three-dimensional positioning, bolt connection, non-welded structure, so as to avoid the welding deformation and stress, to improve the accuracy of the installation. Framework and mounting hole Parts modulus E = 20mm change.
1.2 internal structure to deal with the use of galvanized, external as pickling, Phosphating after electrostatic spraying.
1.3 sub-drawer large, medium and small three and a high of 24E, 16E, 8E (1E = 25mm), each cabinet can be installed a maximum of nine small drawers.
1.4 in the main program of MCC, switchgear is divided into three internal (or b) a regional, bus areas, cable areas, functional unit area (or the bus area, functional unit area), between regions separated by steel plates to ensure that lines normal operation, an effective expansion of the Prevention of Accidents. Outside the cabinet when the drawer out, the inside is not exposed live parts, safe and reliable.
1.5 Functional Unit drawer door with the main switch and the operation of interlocking institutions. When the main switch in the switch to open the door and locking operation of institutions can be locked outside the closing position, between the functional unit compartment separated by metal plates, the drawer has a good interchangeability, and the location of work, test location and isolated location.
1.6 in the capacitance compensation, metering programs, such as fixed cabinets and drawer cabinets have the same appearance, the same level of bus position, thereby ensuring the drawers and cabinets can be fixed side-by-side use.
1.7 Busbar systems: the use of cabinets of the three-phase five-wire bus system. Double the use of standard three-phase copper bus bar, cabinets and counters of the bus used to connect between the blocks overlap, vertical closed bus using galvanized internal partition board arc limit the spread of the neutral busbar located in the front, PE Bus set up at the bottom of the cabinet, and the partition cabinets, doors connected, thus ensuring the continuity of the grounding.
1.8 In case of not lowering the level of protection, the switches at both top and bottom cabinets with natural ventilation openings.
1.9 rating for a protective shell cabinets IP40.
