FIELD: electricity.SUBSTANCE: invention is related to a current collector comprising a sensing element, in particular, for transfer of electric energy from contact wire line to a vehicle. The sensing element is made of fluid-proof tubular profile (18), which may be inserted into a longitudinal cavity inside the carbon current collector. At tubular profile (18) of the sensing element there is at least one preset breaking point.EFFECT: ensuring direct activation of the sensing element when the carbon current collector is damaged by the contact wire line.13 cl, 4 dwg |
