Background
With the rapid development of infrastructure construction in China, high-speed trains become more and more people's trip choices. Modern high-speed electrified high-speed trains acquire electric energy by means of pantograph/contact network systems, so that the requirements of the high-speed trains on power energy are met, namely, contact networks are erected above running rails of the high-speed trains, the pantograph is arranged on the roofs of the high-speed trains, and the electric energy is acquired from the contact networks through contact between pantograph sliding plates and the contact networks. In the running process of a high-speed train, sliding friction with certain contact pressure can occur between a contact net and a pantograph, the contact net is generally made of copper, and the hardness is relatively high; and the contact surface of the pantograph slide plate is generally made of graphite and has lower hardness. For the contact surface of the pantograph slide plate, relative sliding for a long time to a little can cause the pantograph slide plate to be worn out very fast, and the service life of the pantograph is reduced. The traditional solution is to erect the overhead line system in a zigzag shape along the track above the high-speed train track. Therefore, in the running process of the high-speed train, the pantograph is used as a reference object, and the relative contact point of the pantograph and the contact net is constantly changed, so that the pantograph is uniformly abraded, and the service life of the pantograph is prolonged.
However, when the overhead contact system is installed along the track in a zigzag manner above the track of the high-speed train, the length of the overhead contact system line is relatively longer than that of the overhead contact system installed along the track, and the overhead contact system installed in a zigzag manner consumes more raw material copper than that of the overhead contact system installed along the track. According to statistics, the mileage of the Chinese high-speed rail reaches 3.5 kilometers at the end of 2019, correspondingly, a large amount of copper is used for erecting a contact net above a railway, and if the contact net is erected along a track in a zigzag manner, huge waste is generated on copper raw materials.
Therefore, a new pantograph and a matched contact system which can be applied to a linear contact system erected along a track are needed. When the contact net is erected linearly along the rail, copper raw materials are saved, and meanwhile, abrasion and service life reduction of a pantograph caused by contact between the pantograph and a fixed point of the contact net are avoided.
