The main function of the pantograph is to obtain power from the rated voltage DC1500V catenary to supply power to the entire train electrical system. At the same time, the regenerative braking system of the train converts the kinetic energy of the train into electrical energy and feeds it back to the catenary for other online trains. to the role of a two-way transfer hub. The pantograph can be applied to both rigid catenary and flexible catenary lines. In the entire vehicle speed range, the pantograph has good dynamic characteristics, which can ensure good contact with the catenary under various tracks and speeds. Contact state and contact stability.
As an important current-receiving component directly in contact with the main line catenary, the receiving carbon slide plate is installed on the uppermost part of the receiving grid. Our company mainly supplies two kinds of carbon skateboards:
1) Pure carbon graphite skateboard
Use a certain proportion of pitch coke, petroleum coke, graphite powder, carbon black or hard carbon to mix with each other, press and shape it first, and then put it into a high-temperature sintering furnace for roasting. The product can be used on the bow after reprocessing.
2) Copper-impregnated carbon skateboard
This type of slide not only combines the characteristics of high mechanical strength and low resistance of powder metallurgy slides, but also combines the self-lubricating ability of pure carbon slides and the characteristics of less wear on overhead contact nets.
