Intelligent pantograph

Abstract

The invention provides an intelligent pantograph, which belongs to the technical field of railway vehicle equipment, and the intelligent pantograph comprises a pantograph slide plate, spiral excitation coils, a transverse support rod, a pantograph head and a bracket; the bracket is located at the position, under the pantograph slide plate, of the bracket and tightly attached to the pantograph slide plate, the transverse support rod is located below the pantograph slide plate, the spiral excitation coils are spirally wound on the left side and the right side of the transverse support rod, the winding directions of the two sets of spiral excitation coils are opposite, and the two sets of spiral excitation coils are arranged on the bracket. The two ends of the spiral magnet excitation coils are connected with the pantograph head. After the pantograph-catenary arc is generated, a magnetic field is generated to act on the pantograph-catenary arc through the more intelligent structural design, on one hand, the arc root of the arc can move on the sliding plate, and an ablation area is dispersed; on the other hand, the pinch effect of the electric arc can be relieved, the energy density of the electric arc is reduced, and therefore the purposes of relieving ablation of the pantograph-catenary electric arc to the sliding plate and prolonging the service life of the sliding plate are achieved.

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
