Problems solved by technology
[0004] However, in the prior art, the measurement of the stator winding resistance value of the traction motor in the frame-controlled locomotive is based on the assumption that the temperature rise of multiple traction motors on the same bogie is the same ideal state, and the temperature rise of the traction motor of the locomotive is affected by ventilation and heat dissipation, operating conditions The temperature rise of these traction motors is not exactly the same
Therefore, the existing technology cannot accurately detect the actual temperature rise performance of each traction motor

The invention provides a temperature rise performance detection method based on a traction motor in a frame-controlled locomotive and the frame-controlled locomotive, wherein the frame-controlled locomotive runs at a preset speed by controlling the traction motor to be tested in the frame-controlled locomotive and simulating the untested traction motors in the frame-controlled locomotive, and therunning time of the frame-controlled locomotive is recorded, wherein the number of the untested traction motors is one or more; when the driving time reaches a preset time threshold value, the frame-controlled locomotive is triggered to stop driving, and the resistance value of the stator winding of the traction motor to be detected is detected and obtained so as to obtain the temperature rise performance of the traction motor to be detected; the frame-controlled locomotive comprises a traction converter, wherein the traction converter is connected with a traction motor to be tested and is disconnected with the untested traction motors, so that the temperature rise performance of each traction motor in the frame-controlled locomotive is accurately detected.
Description
technical field [0001] The invention relates to the technical field of temperature rise performance detection of a traction motor, in particular to a method for detecting the temperature rise performance of a traction motor in a frame control locomotive and the frame control locomotive. Background technique [0002] In order to test the temperature rise performance of the traction motor, it is necessary to measure the temperature rise parameters of each traction motor. The bridge method is one of the methods. By measuring the resistance value of the stator winding after the traction motor has been running for a period of time, it is compared with that measured at room temperature. The resistance value of the stator winding of the traction motor uses the relationship between the resistance value and the temperature change to calculate the temperature rise of the traction motor, and then calculates and verifies the heating performance of the traction motor. [0003] At present...
