Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to an automatic temperature-controlling carbon fiber heating and deicing device for a medium-low speed maglev transportation power supply rail. Background technique [0002] Medium and low-speed maglev trains are driven by short-stator induction motors, and the induction motor stator installed on the train needs to be powered by the ground. At present, the power supply method of medium and low-speed maglev trains is: install a power supply contact rail on the side of the track beam under the F-shaped suspension guide rail, A lateral current collector is installed at the bottom of the suspension frame of the maglev train. Under a certain pressure, the side current collector sends the ground electric energy to the vehicle through mechanical sliding contact with the power supply contact rail. In the process of taking current from the side current receiver, it is greatly ...

AI Technical Summary

Problems solved by technology

In the process of taking current from the side current receiver, it is greatly affected by the installation accuracy of the power supply contact rail and the smoothness of the track. In winter, the surface of the power supply rail is prone to icing due to rain, snow and low temperature, which will seriously affect the power supply performance. fall, affecting driving safety

[0003] Therefore, it is necessary to study an online temperature measurement and deicing device for the power supply rail of medium and low-speed maglev trains to avoid the problem of unstable current flow due to icing of the power supply rail and affect driving safety, thereby improving the reliability of the system
