Abstract
The utility model discloses a control cabinet with two control systems for use and one for standby for steel mill production, which is mainly composed of a first control cabinet, a second control cabinet and an instrument cabinet arranged in order. The first control cabinet is provided with a controller. The first controller is connected with a first inverter. The first inverter is connected to the first contactor and a second contactor. The second control cabinet is provided with a second controller. The second controller is connected to the second inverter. The second inverter is connected to a third contactor and a fourth contactor. The first contactor is connected to a pump A. The fourth contactor is connected to a pump C. The second contactor is connected to the third contactor and then connected to a pump B. The control cabinet is simple in structure, uses two control systems and two inverters to control three devices, and is improved in efficiency of the control cabinet and reduced in costs.
