> Cabinet put oneself in another's position
- The overall use of 8MF type open section steel, the two sides of the section steel have module 20mm, 100mm and 9.2mm installation holes respectively
There are two types of assembly, full assembly structure and part (side frame and beam) welded structure
- The compartment is divided into functional unit room, bus room and cable room. The function of each room is relatively independent for live maintenance
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- The exterior is coated with electrostatic epoxy powder, which will not take off paint for 50 years
- Molding size, hole size and equipment interval are modularized (modularized E=160mm)
> Functional unit (drawer part)
- The drawer layer height module is 160mm (divided into 1/2 unit,1 unit,3/2 unit,2 unit,3 unit). Maximum rated current of unit loop is 400A
- The drawer changes only in height size, its width, depth size unchanged, the same functional unit of the drawer has a good interchangeability.
- Each MCC cabinet can be equipped with 11 one-unit drawers or 22 1/2 unit drawers, of which more than one unit drawer is equipped with multifunctional back board
- According to the current size of the drawer in and out of the line with different number of pieces of the same specification chip structure plug-in.
- The drawer unit is equipped with mechanical interlocking device. When the main switch is closed, the door panel cannot be opened
- The drawer unit has a sufficient number of secondary connectors to meet the requirements of the number of connections of computer interfaces and automatic control circuits
> Busbar system
- Adopt three-phase four-wire system or three-phase five-wire system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation
- The flat bus arrangement makes the device have good dynamic and thermal stability, and can withstand 80/176kA short circuit current impact
> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers have been trained for at least 6 months
- The secondary connection is automatic terminal crimping machine to ensure reliable connection
- Use power tools to ensure proper torque for bolting reinforcement
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- All kinds of experimental tests before delivery to ensure the normal operation of the equipment
