High Efficiency Pantograph

Abstract

The invention relates to a high power pantograph. The pantograph comprises a connecting rod and a support rod. The connecting rod is provided with a slide block. One end of the support rod is connected with the slide block in hinged mode. The other end of the support rod is placed on a drive shaft of a rotation motor. One end of a telescopic arm is fixedly provided with a slide plate. Inductive solenoids are embedded in the slide plate. The axial line of each inductive solenoid is perpendicular to a contact line of a contact grid. Both the left and right sides of the slide plate are provided with clamp plates. The clamp plates are connected with the slide plate through slide bars. One end of each slide bar is fixedly installed on the clamp plate. The other end of the slide bar extends into the slide plate. A permanent magnet is embedded in the side surface of each inductive solenoid just opposite to the clamp plate. Circuit breakers are placed in all inductive solenoids, and are connected in serial mode. The pantograph has the novel and peculiar structure, can keep enough pressure between the pantograph and the contact grid, at the same time causes no big burden to the contact grid, thus protecting the contact gird in an effective manner, and enhancing the quality of current influx.

Description

technical field [0001] The invention relates to a train assembly, in particular to a pantograph. Background technique [0002] The pantograph is the electrical equipment used by the electric traction locomotive to obtain electric energy from the catenary. It is installed on the roof of the locomotive or motor car; Rod, chassis, lifting bow spring, transmission cylinder, supporting insulator and other components; the current receiving quality of the pantograph is related to the following factors: contact pressure between the pantograph slide plate and the catenary, transition resistance, contact area, etc. ; Therefore, in order to ensure the smooth flow of traction current, a certain pressure must be maintained between the pantograph and the contact wire; the current commonly used pantograph has a complex structure and high maintenance costs. Pressing the catenary to maintain the pressure, this structure will produce an excessive burden on the catenary, affecting the firmnes...
