Abstract

The invention discloses a pantograph-catenary contact wear debris distribution control device and method. The device comprises a magnetic field control module, an environmental data collection module and a PC server; the magnetic field control module and the environmental data collection module are both connected to the PC server; the PC The server controls the current intensity of the magnetic field control module according to the data of the environmental data acquisition module, so that a specific magnetic induction intensity is generated in the contact area of ​​the pantograph-catenary friction pair, so that the distribution of wear debris in the contact area is in an optimal state; the present invention reduces the friction coefficient, improves the The surface roughness realizes the mechanical and electrical balance of the pantograph-catenary system, improves the severe mechanical wear of the pantograph slide plate and the catenary wire, and also improves the energy transmission efficiency and electrical contact characteristics of the pantograph-catenary system, and the structure is simple and the effect is Significant, with strong practical value and promotion value.

Description

technical field [0001] The invention belongs to the field of magnetic field control technology and pantograph-catenary technology, and in particular relates to a pantograph-catenary contact wear debris distribution control device and method. Background technique [0002] The electrified locomotive obtains electric energy from the catenary wire through the pantograph slide plate, so the stability of the pantograph-catenary system directly affects the current quality and running state of the train. With the advancement of high-speed trains, the mechanical wear of the pantograph-catenary contact pair continues to increase, which greatly increases the maintenance cost of the pantograph-catenary system, reduces the service life of the slide plate and wires, and may even cause pantograph-catenary accidents in severe cases, resulting in irreparable personnel property loss. [0003] The carbon slide has a layered structure, which has occupied the railway market for a long time with...
