Thermal analysis of electrical contacts from pantograph–catenary system for power supply of electric vehicles

Experimental study on the temperature of the contact strip in sliding electric contact

“…Bucca and Collina 19,20 also concluded that the friction and electrical effects control the wear in the sliding electrical contact of the contact strip and wire. Nituca 21 proposed a thermal model to evaluate the temperature distribution on the sliding electrical contact. However, it appears that there are very limited study works on the temperature of the contact strip in the literature.…”

Electrical conductivity and wear behavior of bi-continuous Cr3C2–Cu composites

“…Therefore, the overall conductivity of composite D was much lower than that of composite B. However, all four Cr 3 C 2 -Cu composites still exhibited much lower electrical resistivities than common pure carbon strips ($ 1.7 μΩ m [1]) and copper-impregnated carbon materials ($ 1.8 μΩ m [9]). …”

“…Two main challenges of these applications are to minimize both arc discharge (which occurs when contact is lost between the two conductors, due to the mechanical separation) and thermal wear [1,2]. In the past decades, pure metal, pure carbon, powder metallurgy composites and metalimpregnated carbon have been successively studied to address these challenges [3][4][5][6][7][8][9][10].…”
