Benefits of technology

The technical effect that this patented technology helps prevent damage caused by cracks on steel plates used for electricity transmission or distribution purposes are improved durability against crackings while maintaining good conduction properties. This results in better performance over time without requiring frequent maintenance replacements.

Problems solved by technology

This technical problem addressed in this patents relates to improving the conductance and frangrance resistances of traditional carbon materials used for railway vehicles' use due to their low conductivities and frictions caused by insufficient lubrication between them and wire surfaces.

specific Embodiment approach

[0030] Specific implementation method: participate in Figure 6 A method for preparing the main carbon strip structure of a pantograph carbon slide, including the steps of mixing carbon powder into asphalt material and pressing to obtain the main carbon strip, and fixing the main carbon strip on the aluminum support by bonding The step is characterized in that after the main carbon strip is formed, it is put into engine oil and boiled, and then kept at 65-85°C for 48-72 hours.

[0031] Like this, through above-mentioned method, can make the upper surface of main carbon bar generate one layer of oil film layer. In this way, the oil film layer can be relied on to better reduce the friction and improve the sliding effect.

[0032] The oil film layer prepared by the above method can make the oil molecules bond and attach around the carbon particles on the surface of the main carbon strip, greatly improving the sliding friction effect of the carbon particles on the surface of the mai

Abstract

The invention discloses a pantograph carbon contact strip main carbon strip structure preparation method. The method includes the steps that carbon powder is mixed with a bituminous material evenly and pressed, so that a main carbon strip is obtained; and the main carbon strip is fixedly arranged on an aluminum carrier in an adhesive mode. The method is characterized in that after being formed, the main carbon strip is placed in engine oil, and after the engine oil is boiled, the main carbon strip stays in the engine oil for 48 to 72 hours with the temperature kept between 65 DEG C and 85 DEGC. The method has the beneficial effects that the work friction resistance of the main carbon strip can be reduced, the anti-cracking capacity is improved, the electric conductive performance of the main carbon strip can be improved, the process is simple, machining is convenient, quick and safe, and the product quality is stable and reliable.
