Summary:A direct power supply system intelligent test device relates to the field of locomotive detection. The equipment comprises an information acquisition module, a protection and measurement device, a controller, a load cabinet access selection switch group, a load cabinet group, an overvoltage/undervoltage prompt module and a serial port communication module, the information acquisition module acquires information of a train direct-current power supply and sends the acquired information to the controller; the protection and measurement device performs grounding protection function test and leakage current test on the train direct-current power supply, and sends results of the grounding protection function test and the leakage current test to the controller; the controller is used for controlling the load cabinet access selection switch group to connect or disconnect the load cabinet group, and is also used for controlling the overvoltage/undervoltage prompt module to send an overvoltage/undervoltage prompt; the
