[0002] The pantograph sliding plate structure with de-icing function is a key component of the pantograph of an electric locomotive, usually installed on top of the pantograph. It makes direct contact with the overhead contact line and is used to transmit current. The sliding plate is generally made of carbon-based materials, possessing good conductivity, wear resistance, and self-lubricating properties. Its structural design must meet requirements such as stable contact with the overhead contact line and adaptability to different operating speeds and environments to ensure that the electric locomotive reliably obtains electrical energy from the overhead contact line and ensures the normal operation of the train.

[0003] The pantograph sliding plate structure with de-icing function obtains electrical energy through close contact with the overhead contact line. When the pantograph is raised, the sliding plate, under the pressure of a spring, rises and adheres to the contact line. Due to the good conductivity of the sliding plate, the current in the contact line is conducted through the sliding plate and pantograph to the electrical equipment inside the locomotive, providing power for train operation. At the same time, the material properties of the sliding plate enable it to maintain stable performance under high-speed friction, ensuring reliable power transmission and a long service life.
