The disclosed contact strip comprises a wear strip (3) which is intended to come into contact with a catenary and is made of a first electrically conductive material, a pipe (4) suitable for containing a pressurised fluid, and connecting means capable of linking said pipe to a pneumatic circuit. According to the invention, the strip further comprises at least one electrically conductive element (5), referred to as an electrical detection element, made from a second electrically conductive material that has higher electrical conductivity than the first electrically conductive material, said electrically conductive element (5) being interposed between the pipe and the top surface of the wear strip (3), and connection means (71, 72) connecting said electrically conductive element (5) to an electrical detection circuit (8) incorporating said electrically conductive element. The invention therefore helps avoid, to a large extent, the emergency lowering of the pantograph arm as the operatoris warned, by means of this conductive element, that the contact strip is in an ''intermediate'' state of wear.
所公开的接触片包括旨在与悬链线接触的防磨片(3),且该防磨片由第一导电材料制成,该接触片还包括适用于容纳加压流体的通道(4)以及能够将所述通道链接至气动电路的连接装置。根据本发明,该片还包括称为电检测元件的至少一个导电元件(5),该导电元件由导电率大于第一导电材料的第二导电材料制成,所述导电元件(5)插入在通道与防磨片(3)的顶表面之间,并且连接装置(71,72)将所述导电元件(5)连接至包含所述导电元件的检测电路(8)。由于操作人员通过该导电元件被警告接触片处于“中等”磨损状态,因此,本发明在很大程度上帮助避免受电弓臂的紧急下降。
