电力机车受电弓发展综述

电力机车速度不断提高导致弓网电弧加剧,已经严重制约了高速铁路的发展.本文从受电弓的结构和滑板材料角度阐述国内外电力机车减小弓网电弧危害的现状以及发展,并分析了受电弓滑板的发展趋势.最后从电气角度分析了弓网电弧的产生机理,指出在现有的机械手段的基础上还应结合弓网电弧的电气特性进行研究,从而找到抑制和消除弓网电弧的方法.

Overview on Development of Pantograph of Electric Locomotive

The speed of electric locomotive accelerating continuously result in the picking up of bow net arc,which has seriously impeded the development of China's high-speed railway.From the pantograph's structure and the slide material angle,this article expatiate the status that how to decrease the harm of arch network arc and its development internal and external on the electric locomotive.And the development trend of the pantograph slide plates is also analyzed.Finally analyzing the generation mechanism of the arch net arc from the electric angle,pointed out that suppressing the bow net electric arc except in the existing mechanical method foundation,we should also unify the its electrical specification to research,so as to find the method of suppressing and eliminating it.
