摘要（英）：

The invention discloses a vehicle-mounted integral three-phase direct-current resistance, transformation ratio and load comprehensive testing device and a method. The testing device comprises a vehicle-mounted personal computer (PC), a relay control and communication switching unit, a three-phase direct-current resistance, transformation ratio and load comprehensive testing unit and a relay board used for switching a testing line. The vehicle-mounted PC carries out testing data communication with the three-phase direct-current resistance, transformation ratio and load comprehensive testing unit through the relay control and communication switching unit, and the relay board is connected with the testing line of the three-phase direct-current resistance, transformation ratio and load comprehensive testing unit. According to the vehicle-mounted integral three-phase direct-current resistance, transformation ratio and load comprehensive testing device and the method, a measurement process is automatic, testing time is shortened, occupied space is small by means of effective functional rectification, wiring times are reduced, work efficiency is improved, labor intensity is lowered, three tests of transformation ratio, load and direct current resistance are finished in one-time wiring mode, time and labor are saved, and application prospects are good.
