Various series of low-voltage withdrawable switch cabinets, drawer cabinets and cabinets
Product introduction
1. Overview of switch cabinets:
Low-voltage withdrawable switch cabinets are suitable for three-phase AC frequency with rated operating voltage of , rated current It is used for power, distribution and motor centralized control and capacitance compensation in power generation and power supply systems of and below. It is widely used in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other places. This product complies with 3-, B., B/ and other standards
This cabinet adopts a new manufacturing process, and each functional unit adopts Modular design, flexible and convenient unit combination, can replace all solutions and functions currently on the market.
2. Switch cabinet structure description:
The cabinet adopts a modular assembly structure, and the frame is assembled from B profiles. The horizontal busbar is placed on the top of the cabinet. The top of the cabinet adopts an open structure. The top cover can be opened. The cabinet is equipped with a back door. The outlet method is rear outlet, making installation and maintenance more convenient. The drawer is operated by opening the door. When opening the door, the drawer adopts the 3 (rotating three-station) push mechanism and the B (handle three-station) and (rotating three-station) push mechanism. The primary plug-in adopts a new valveless method, which has higher reliability. The unit circuit can achieve a rated current of 3 and below, in which the unit drawer current can reach /.3. Cabinet protection level.
Three: Main features of the switch cabinet:
The whole cabinet adopts an assembled combination structure and is installed in a modular manner. The parts have strong versatility, good applicability and high degree of standardization
, the effective functional unit height of the drawer cabinet, the height of the drawer unit is /3, etc.
to ensure safety
, the drawer compartment in the cabinet The door and the switch operating handle of the circuit breaker or isolating switch are equipped with mechanical interlocking. The door can only be opened when the handle is in the breaking position
. The drawer of the cabinet adopts a mechanical three-station mechanism (including /drawer) with three positions. (Separation, testing, connection)
, using high-reliability primary connectors
, the material can be cold-rolled plate, galvanized plate, aluminum-zinc coated plate.
