NOVELTY - The utility model claims a pantograph breaking device for electric locomotive, relating to the technical field of electric locomotive charging, specifically to a pantograph breaking device for electric locomotive, comprising an upper frame; the top of the upper frame fixedly connected with with a carbon sliding plate; the upper surface of the carbon sliding plate fixedly connected with graphene alloy bump; the inner side of the upper frame fixedly connected with with a balancing rod; the connecting rod of the upper frame close to the bottom is movably sleeved with a first movable shaft; the right lower part of the first movable shaft fixedly connected with a lower arm rod. The pantograph breaking device for electric locomotive is composed of a groove formed between the graphene alloy bumps, and the width of the groove formed between the graphene alloy bumps is greater than the diameter of the contact, which can make the catenary fixedly added and increase the catenary contact enhancing the smoothness between the carbon sliding plate and the catenary so as to make the operation of the electric locomotive more stable.
