Cabinet
In the cabinet all thyristors and diodes for platform products. Including rectifier and inverter.
The power cabinet is made of high strength cold rolled steel sheet, 2 mm thick. Open the door, you can easily access the rectifier and inverter parts. Domestic brands use copper and copper power cabinet, copper oxidized production specification. The layout of power supply cabinet is reasonable, easy to maintain, line running and wiring specification (with drawings). The maintenance personnel can easily access all the maintenance points.
Inlet air switch protection system.
a.The quick action full circuit breaker is installed on the front of the power supply and separates the 400V power supply line from the transformer and the power supply cabinet. Switch to delixis switch plant products. When a fault occurs, immediately trip to protect the power cabinet from further damage. It is operated by an electric operating mechanism and has a 400V coil that serves as an interlocking protection.
b. With over-current protection, when the over-current occurs, it trips the protection action, cut off the power supply to the power supply cabinet.
c. Isolation control room:
A closed isolation control room is arranged on the upper part of the front door, which is equipped with the main control board, feedback board, control power and other control components, so that the signal of the main control board can be conveniently observed. The isolation control room does not require additional cooling. The main power electronic components of the power cabinet are water-cooled, and the temperature rise during the operation of the cabinet will not affect the isolation control room. At the same time, the selection of all electronic components on all electronic control circuit boards in the isolation control room is carried out according to the high temperature level. (basically all components on PCB are internationally famous brands).
