The flow cabinet primarily provides traction power for overhead electric locomotives used in mines and tunnels, converting alternating current into direct current for transmission to the locomotives.

Mining Rectifier Cabinet). The rectifier cabinet is a power unit that converts alternating current into direct current. The rectifier cabinet utilizes a three-phase bridge rectifier circuit structure with opposite parallel diodes.

Rectifier cabinet function:

1. Rectifier cabinets are used to convert the 100HZ three-phase AC power output from the main exciter to a three-phase full-wave bridge rectified DC current for the motor's rotor. For the reliability of the generator's rotor current, there are usually two or three rectifier cabinets. In normal operation, they operate in parallel.

2. The rectifier cabinet converts the three-phase AC voltage from the excitation transformer into DC voltage (using a three-phase bridge rectifier).
