In order to study the influence of wet electric pantograph slide abrasion

using catenary electromagneticnoise experiment platform

the current-carrying wear experiments of 4 kinds of wet conditions are carried out

thecurrent-carrying wear characteristics and surface morphology of slide plate of Cu impregnation carbon under differ-ent wet conditions are analyzed. There is an optimum humidity between the pantograph and catenary system

whichis helpful to reduce the arc and the slide plate wear. At the same time

the changing process of wear mechanism un-der four kind of damp conditions is

arc erosion wear is accompanied by slight mechanical wear

mechanical wearand arc erosion wear

under normal conditions

slight mechanical wear to heavy mechanical wear accompanied mi-nor arc erosion

and finally changed to coexistence of mechanical wear and arc erosion. It provides a basis for thestudy of pantograph mesh wear under special conditions.
