The invention discloses a double-ring type current collection-grounding compatible system suitable for a high-speed railway. The double-ring type current collection-grounding compatible system comprises a pantograph assembly and a backflow pantograph assembly which are symmetrical in structure. An annular pantograph head of the pantograph assembly is hinged to a pantograph base through a support structure. A pantograph head groove shell is of an annular structure, an annular groove is formed in the top of the pantograph head groove shell along the annular face, an annular carbon sliding blockbase is arranged in the groove, a base rolling shaft is arranged between the bottom of the carbon sliding block base and the bottom of the groove, a brush and a rolling shaft are fixed to the groove walls of the two sides of the groove through springs, and the brush is connected to a leading-out cable. An annular carbon contact strip is fixed above the carbon sliding block base through an insulating pad; an annular carbon contact strip in the pantograph assembly makes contact with an overhead line system for current collection, and an annular carbon contact strip in the backflow pantograph assembly makes contact with a backflow line for backflow. According to the invention, large current is prevented from acting on the fixed current collection brush for a long time, the brush is preventedfrom excessive electrochemical erosion, and the service life of the current collection brush is prolonged.
本发明公开一种适用于高速铁路的双环型“受流‑‑接地”兼容系统,包括结构对称的受电弓组件和回流弓组件;受电弓组件的环形弓头通过支架结构铰接于受电弓底座上;弓头凹槽外壳为环状结构,其顶部沿环面设有环形的凹槽,凹槽设有环形的碳滑块底座,碳滑块底座底部与凹槽底部之间设有底座滚轴,凹槽两侧槽壁上通过弹簧固定有电刷和滚轴,且电刷连接到引出电缆线上;环形碳滑板通过绝缘垫固定于碳滑块底座上方;受电弓组件中的环形碳滑板与接触网线接触受流,回流弓组件中的环形碳滑板与回流线接触回流。本发明避免了大电流长时间作用于固定的受流电刷上,避免电刷受到过度的电化学侵蚀,延长了受流电刷的使用寿命。
