粉末冶金电力机车受电弓滑板的研究概况

目前,我国电力机车用各类滑板中,铜基粉末冶金滑板应用最为广泛,日本新干线长期使用粉末冶金滑板.本文全面地综述了电力机车受电弓粉末冶金滑板的发展应用概况,介绍了粉末冶金滑板的材料及制造工艺、铜基滑板的标准及选用原则.与进口的整体碳滑板相比,粉末冶金滑板机电性能优良,电阻率低,适用性好,不易出现弓网故障,借鉴日本新干线的成功经验,铜基粉末冶金滑板在今后的很长时间内仍将居于主导地位.今后,粉末冶金滑板应适当增加润滑组元含量,以减少对导线的磨耗为发展方向.

RESEARCH ON POWDER METALLURGY PANTOGRAPH STRIPS FOR ELECTRICAL LOCOMOTIVE

Nowadays,powder metallurgy copper based strips are widely used in our country,powder metallurgy strips are also used at Japan's Xin'ganxian.The development & usage of powder metallurgy strips are generally summarized,with manufacture technology standards and selection principle.Powder metallurgy strips have high mechanical & electric properties,low resistance,good applicability,less trouble,and low cost.So,powder metallurgy strips will exist for a long time.Increasing lubricant content of powder metallurgy copper based strips,to reduce wear of conductors is the trend of further development.
