The invention relates to the technical field of electrified railway locomotives, and discloses a magnetic repulsion type suspension pantograph which comprises a base, a pantograph head support and a carbon sliding plate, the carbon sliding plate is arranged on the pantograph head support, an electromagnetic mechanism for driving the pantograph head support to ascend and descend is installed on the base, and the electromagnetic mechanism comprises an inner cylinder, an outer cylinder, a permanent magnet and an iron core. The carbon slide plate is arranged on the outer top of the outer cylinder, the inner cylinder is fixedly arranged on the base, the permanent magnet is arranged on the outer cylinder, the iron core is arranged on the inner cylinder, the solenoid is wound on the iron core, the base is provided with a control circuit board for controlling the magnitude of exciting current in the solenoid, and a pressure sensor is arranged in the outer cylinder. The pantograph-catenary current collector has the advantages that the pressure sensor is used for monitoring pantograph-catenary contact pressure in real time and feeding back the pantograph-catenary contact pressure to the control circuit board, the control circuit board adjusts exciting current according to a pressure value and a built-in control algorithm, it is guaranteed that pantograph-catenary contact force is stabilized at a set value, and therefore the pantograph-catenary current collection quality is guaranteed.

    本发明涉及电气化铁路机车技术领域,公开了一种磁斥型悬浮受电弓,它包括底座、弓头支架以及碳滑板,碳滑板设置在弓头支架上,底座上安装有驱动弓头支架升降的电磁机构,电磁机构包括内筒、外筒、永磁铁以及铁芯,碳滑板设置在外筒的外顶部,内筒固设在底座上,永磁铁设置在外筒,铁芯设置在内筒,铁芯上缠绕有螺线管,底座上设置有控制螺线管内励磁电流大小的控制电路板,外筒的内设置有压力传感器。本发明的有益效果是:压力传感器用与实时监测弓网接触压力,并反馈给控制电路板,由控制电路板依据压力值和内置控制算法,调整励磁电流,保证弓网接触力稳定于设定值,以此保证弓网受流质量。
