Investigation on characteristics of the contact resistance of pantograph -catenary syste m
摘要
Abstract
The contact resistance between pantograph and catenary is an important indicator of contact perform-ance of pantograph -catenary system.The traction current,contact pressure and sliding speed are important fac-tors affecting contact resistance between pantograph and catenary.By the trial of observing static and dynamic contact resistance of pantograph -catenary system on conditions of different current,the variation tendency of contact resistance with traction current,the effects of contact pressure and sliding speed on dynamic contact re-sistance were expounded,and the three factors’effecting mechanisms were analyzed.Studies show that:static and dynamic contact resistance both decrease with increasing current,meanwhile the rate of decline tend to smooth.In the same traction current,greater contact pressure leads to the smaller dynamic contact resistance and faster speed would result in the greater dynamic contact resistance.Besides,faster speed would lead to the steep-er tendency of the dynamic contact resistance with the increase of current.关键词
