Problems solved by technology

[0006] There are many factors that lead to arcing, but in the end they all come down to the contact resistance between the skateboard and the catenary. Excessive contact resistance and large fluctuations in contact resistance during operation are difficult to overcome in the current way of receiving current from the rigid skateboard of the pantograph. Defects
Although R&D personnel have taken various measures for a long time, such as the development of low-resistivity slide materials, such as metal-impregnated carbon slides, powder metallurgy slides, titanium-silicon-carbon high-speed train pantograph slides, etc., due to the rigid surface of the slide and the contact surface of the catenary The number of conductive spots cannot be effectively increased, so the effect of reducing arcing only by improving the skateboard material is not ideal
It can be seen that it is unrealistic to completely eliminate the arcing phenomenon of the pantograph-catenary system for the current traditional pantograph sliding plate receiving current and electricity. Only by changing the vibration characteristics of the pantograph-catenary system, selecting appropriate contact pressure and matching materials , Improve the production process of the contact wire, improve the construction quality of the catenary, etc., to minimize the arc of the pantograph-catenary system

Abstract

The invention discloses a pantograph pan with a flexible electric brush. The pantograph pan is mainly composed of three parts including a rigid conductive panel, the flexible electric brush and a bottom plate. The rigid conductive panel can be a pure-carbon plate or a metal impregnation carbon plate or a powder metallurgy plate or a carbon fiber enhanced composite carbon plate. The flexible electric brush is an electric brush made of conductive fibers. The conductive fibers can be carbon fibers, graphite fibers or metal fibers or fibers achieved by blending the carbon fibers, graphite fibers and metal fibers to a scale, and are also doped with high temperature resisting aramid fibers of a certain scale. The rigid conductive panel and the flexible electric brush both adhere to the bottom plate through conductive glue. When the pantograph pan slides forwards, a contact net makes full contact with the conductive fibers on the flexible electric brush besides making contact with the rigid conductive panel, multidirectional stereoscopic friction is formed, and the purpose of current-feeding power supply is achieved; electric arcs are greatly reduced, electric abrasion to pantograph catenary is reduced, the service life of a pantograph and the pantograph pan is prolonged, and the maintenance and replacement cost are decreased; the pantograph pan is suitable for not only low-speed trains but also high-speed trains.

Description

Technical field [0001] The invention belongs to the technical field of pantograph devices for rail trains, and specifically relates to a pantograph sliding plate with a flexible electric brush. Background technique [0002] The pantograph is the electrical equipment used by the electric traction locomotive to obtain electric energy from the catenary, and is installed on the roof of the locomotive or motor car through insulators. When the pantograph is raised, its sliding plate is in contact with the catenary wire, and electricity is drawn from the catenary wire for traction locomotives and other electrical equipment. At present, the most popular single-arm pantograph is composed of a skateboard, upper frame, lower arm rod, underframe, bow lifting spring, transmission cylinder, support insulator and other components. Among them, the skateboard is one of the most important parts of the pantograph. The catenary wire constitutes a pair of special friction pairs that are mechanically...
