Simulation and Verification of Effect of Arc Duration on Arc Temperature Based on COMSOL
Machines, 2023 The pantograph–catenary arc of urban rail has the characteristic of high temperature, which directly acts on the surface of the pantograph–catenary system, will seriously ablate pantograph and contact line, and affect the flow of the pantograph–catenary ...
