A smart pantograph

Abstract

The invention provides an intelligent pantograph, belonging to the technical field of rail vehicle equipment, comprising a pantograph slide plate, a spiral excitation coil, a transverse support rod, a pantograph bow head and a bracket; The position of the bracket directly below the pantograph slide, and close to the pantograph slide, the lateral support rod is located under the pantograph slide, the helical excitation coil is wound on the horizontal support rod by helical The left and right sides, and the winding directions of the two sets of spiral excitation coils are opposite, and the two ends of the spiral excitation coils are connected with the pantograph head. When the pantograph-catenary arc is generated, through its more intelligent structural design, the generated magnetic field acts on the pantograph-catenary arc. On the one hand, it can move the arc root on the slide to disperse the ablation area; on the other hand, it can Slow down the "pinch" effect of the arc, reduce the energy density of the arc, so as to achieve the purpose of reducing the ablation of the pantograph arc on the skateboard and prolonging the service life of the skateboard.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle equipment, and in particular relates to an intelligent pantograph. Background technique [0002] The train obtains electric energy through the close contact between the pantograph slide plate and the catenary on the roof. However, with the development of modern technology and the continuous improvement of the train speed, the vibration between the pantograph and the catenary has also intensified. It is difficult for the slide plate and the catenary to maintain a close mechanical Contact, the generation of electric arc is unavoidable. Due to the existence of the "pinch" effect of the arc, it has the characteristics of concentrated energy density and high temperature, which tends to cause serious ablation of the pantograph slide. Therefore, it is imminent to alleviate the ablation of the arc on the slide. [0003] At present, although the skateboard material can be improved by adding metal ma...

AI Technical Summary

Problems solved by technology

[0003] At present, although the skateboard material can be improved by adding metal materials into the carbon skateboard to improve the resistance of the skateboard to the high temperature of the arc, however, due to the development of high-speed trains, the vibration between the pantograph and the catenary is more frequent, and the frequency of arc occurrence is also increasing. Even if the sliding plate material has the best resistance to high temperature, it is impossible to withstand long-term arc ablation

Therefore, it is not enough to rely solely on improving the resistance of the skateboard to the arc
