Problems solved by technology

The splicing of the two ends of the skateboard will cause abnormal air leakage at the splicing of the two ends of the skateboard, which will cause the locomotive to bow down and cause abnormal parking on the road, which will also cause major accidents in line operation safety
Moreover, the metal impregnation process will change due to the formation of the open porosity of the carbon-based material after roasting. It is difficult to control artificially, resulting in insufficient metal impregnation and impregnation, which seriously affects the conductivity and strength of the skateboard.

The pantograph pan of the high-speed railway motor train unit is mainly prepared from the following raw materials in parts by weight: 1-10 parts of carbon material, 0.3-1.5 parts of graphite, 1.4-4.7 parts of seepage metal and 2.1-5.8 parts of molten pitch. The pantograph pan of the high-speed railway motor train unit, provided by the invention, has the advantages of good electrical conductivity, small resistance, electric arc cauterization resistance, strong shock resistance and long service life.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a pantograph slide plate of a high-speed railway EMU and a preparation method thereof. Background technique [0002] In recent years, with the rapid development and construction of my country's high-speed railway network, the introduction and manufacture of high-speed EMUs is also accelerating. The operation of high-speed electric locomotives relies on high-voltage power supplies to drive high-speed motors to run at high speeds, and the high-voltage wires and high-speed locomotive workshops need to have a high-voltage power supply that connects the wires to the high-speed locomotives and continuously receives them at speeds of 300-400 kilometers per hour. current-powered components. This important part connecting the high-speed locomotive and the high-voltage wire is also called the pantograph slide plate of the high-speed railway EMU. This part should adapt to high-speed friction, anti-...
