Description

Technical Field

[0002] The electrification and high-speed of railways are the current trends in the development of world railway transportation. With the rapid development of the economy, higher requirements are also put forward for the pantograph-catenary system. The pantograph-catenary system is the main power source for the operation of electric trains. It mainly consists of two parts: the catenary and the pantograph. Most of the catenary wires are made of pure copper or copper alloy materials. As the skid material for electric locomotives to introduce electric energy from the catenary wire, its development has experienced a long and complex process.

[0003] Referring to the Chinese patent with the existing publication number CN110576747B, it discloses a pantograph skid. A specific embodiment of the device includes: an axially symmetric body, the body includes a slider main part, slider end parts located at both ends of the slider main part, arc hooks located at both ends of the slider end parts, wire retention flat end parts located at both ends of the arc hooks, and anti-scratch arc points located at both ends of the wire retention flat end parts; the slider end parts are connected to the arc hooks by an embedding method; a convex structure is provided on the top surface of the wire retention flat end parts.

[0004] By setting the convex structure on the pantograph skid, the above-mentioned device is beneficial to prevent the catenary wire from slipping below the pantograph skid and causing major train operation accidents.
