Abstract
The invention discloses a current synchronization testing apparatus of a traction motor. The testing apparatus comprises an input module, a comparison circuit, a relay, and a display module. The input module, the comparison circuit, and the display module are connected successively to form a series loop connected with a vehicle traction loop externally. The output terminal of the comparison circuit is connected with the relay; and a normally-open contact of the relay is connected with the vehicle traction loop.

Current existing adjustment method, when verifying four traction electric machine phase sequences, needs to remove four connection box for motor three lead-in wire to measure, bogie locational space is the least, plus without specialized maintenance trench, the most cumbersome and be difficult to operate during verification wire, debugging efficiency is low.
One joint train has four motors, and each bogie is 2 motors.
Summary of the invention
It is an object of the invention to, for the defect overcoming prior art to exist, improve work efficiency, the operation easier reducing debugging employee and intensity, improve enterprise's commissioning device level, propose a kind of traction motor current synchronous testing device and method.
The present invention adopts the following technical scheme that traction motor current synchronous testing device, it is characterized in that, including input module, comparison circuit, relay, display module, described input module, described comparison circuit, described display module are in turn connected to form series loop, described series loop external vehicle traction loop, the outfan of described comparison circuit is connected with described relay, and the normally-closed contact of described relay is connected with described vehicle traction loop；Described input module includes that four Hall current sensors, four current clamps, the input of described Hall current sensor, the input of described current clamp are connected with by any phase line of measured motor respectively；Described display module is used for showing that by the bogie on measured motor be 1 axle or 2 axles.
The present invention also proposes traction motor current synchronous detecting method, it is characterised in that specifically include following steps:
Hall current sensor, current clamp are opened and are clamped by any phase line of measured motor by step SS1, then will be caused in the compartment that train is measured by the phase line of measured motor；
The vehicle launch pulling test action of step SS2, four Hall current sensors, four current clamps gather four motor working current, it is respectively compared the phase-sequence current of each motor and the size of normal phase-sequence current, if bigger than normal phase-sequence current 5-7 times of the phase-sequence current of certain motor, or it is worth the least, then judge that this motor phase sequence is abnormal, proceed to step SS3, otherwise judge that the phase sequence of each motor connects correct；
