■ characteristics of
This series of products with high breaking capacity, dynamic stability, and structure of advanced, reasonable, realistic electric program, serial, high universality, any combination of the various program modules, one of the cabinets to accommodate more of the loop, saving accounts in size, pleasing in appearance, highly protective, safe, reliable, easy maintenance, etc.. The products comply with national standards IEC439 and GB7251.1-1997 "Low-voltage switchgear and control equipment" and other related standards.

■ structural characteristics
This series of products for the combination of the basic Shelves fabricated structures, structural Shelves all connected through the screw fastening into the basic framework, and then need to add doors, baffle, partition, drawer, mounting brackets, as well as bus and electrical group items such as spare parts, assembled into a complete switch cabinet, the cabinet has the following characteristics:
□ framework used type of steel, bolts to connect non-welded structure so as to avoid the welding deformation and stress, to improve the accuracy of the installation.
□ hole framework and components installed by E = 25mm modulus changes.
□ internal structure to deal with the use of zinc. External by pickling and phosphating treatment, the use of electrostatic spraying of epoxy powder.
□ in the power centers (PC) into the inside lane, bus level at the top for the region, the lower the level of the region for the circuit breaker bus bar room, the domestic circuit breakers can be configured CW1, RMW1, HLW1, HA series can also be configured according to user needs Foreign Electric Company produced a variety of circuit breakers, such as: ABB company's F series of circuit breakers, and other intelligent circuit breaker.
Under normal circumstances, PC unit with double rows of the main circuit (including the mother), the rated current 630A ~ 1600A at the time, accounting for a size 800 × 1000 × 2200 (width × high × deep) of the cabinets. Pai did not turn to occupy the main circuit size for a 800 × 800 × 2200 (width × high × deep) of the cabinets. Rated current 1600A ~ 3200A in the time, accounting for a size 1000 × 1000 × 2200 (width × high × deep) of the cabinets. Pai did not turn to occupy the main circuit size for a 1000 × 800 × 2200 (width × high × deep) of the cabinets. Power center (PC) feed into the line of cabinets and counter structure similar to feed current 630A ~ 1600A, a 1000 × 1000 × 2200 (width × high × deep) cabinets of the two loops can be installed for the whole layout of the installation .

□ Motor Control Center (MCC) have a wall switch cabinet installation and the installation of two kinds of wall, the top level bus for the region, the region below the level of bus functional unit for the drawer area, the region with a width of 600mm, the installation of the drawer function unit area for the high-1800mm, when the installation of cabinets for the wall, the cabinet left the Department for the functional unit area, the right of a round cable 200mm wide region, size cabinets for the 800 × 500 × 2200 (wide × deep × H), when away from the wall cabinets for installation, cabinets width of 600mm, cable round the back of the district in the cabinets, cabinets for the size of 600 × 800 (1000) × 2200 (width × high × deep) . Depth cabinets have two kinds of 800 and 1000, we recommend that users choose deep cabinets 1000 to counter the depth of unity with the PC, when the drawer out of the counter outside the non-exposed live parts inside, safe and reliable
□ drawer functional unit with the door switch operation by the mechanical interlocking institutions, switches in the switch to open the door location and operation of institutions in addition to the padlock can be locked in position switch or gateway. Functional unit between compartments separated by metal plates, the drawer has a good interchangeability and have jobs to test the location and isolated location. When pushed to a position of the drawer, the drawer automatically positioning, this time pulling to the left drawer drawers drawing board to the lifting position, into the next location outside the cabinet when the drawer out with anti-off function.
□ in the capacitance compensation, metering programs, such as fixed-style cabinets and drawer cabinets have the same appearance, the same level of bus location. To ensure that the drawer-type cabinets with fixed side-by-side to use.
□ bus systems: the use of cabinets of the three-phase five-wire bus system, the level of busbar rated current 1600A and below in a single busbar, busbar rated current level of more than 1600A when used in dual-bus, between the cabinet and the cabinet level of bus used to connect blocks overlap, the use of galvanized plate vertical busbar closed arc internal partition limit the spread of the neutral bus at the counters set up at the top of the front to protect the busbar (PE) set up at the bottom of the cabinet and cabinets of the partition, connected to the door, thus ensuring the continuity of the grounding.
□ without lowering levels of protective shell, the switch has a counter at the bottom and top of windows for natural ventilation.
□ cabinets for shell protection grade IP30.
