Control cabinet for mining fan test bed

The invention relates to a control cabinet for a mining fan test bed. A control core is a programmable logic controller (PLC); two communication ports are formed in the used PLC; one communication port of the PLC is electrically connected with a communication port of a touch screen; the other communication port of the PLC is electrically connected with a communication port of a computer; an output port of the PLC is electrically connected with forward and reverse direction control ports and high-medium-low frequency setting ports of a frequency converter I and a frequency converter II. According to the control cabinet for the mining fan test bed, the operating condition of the fan test bed can be monitored by both the control cabinet and the touch screen and the computer. The control cabinet can also respectively display a power supply voltage and three-phase currents, active powers and motor operating frequencies of two motors.
