The invention discloses a graphene current sensor, and belongs to the technical field of graphene sensors. The graphene current sensor comprises a protection shell, wherein the bottom of an inner cavity of the protection shell is movably connected with a supporting mechanism, and the outer side wall of the supporting mechanism is connected with a heat dissipation mechanism in an inserted manner. According to the graphene current sensor, heat can be absorbed through the heat dissipation shell which absorbs heat, the heat conduction pad outside the heat dissipation shell can guide the heat into the protection shell, and meanwhile, the contact area with air can be increased through a plurality of external exhaust holes, so heat dissipation processing can be effectively carried out on the internally fixed graphene inductance element; therefore, the influence of heat accumulation on working efficiency and the durable service life of the graphene electricity-sensing element can be effectively avoided, insertion positioning accuracy of the graphene electricity-sensing element is effectively improved through the heat dissipation shell designed in a stamping mode, processing and maintenance difficulty is reduced, meanwhile, supporting protection can be conducted through the heat dissipation shell absorbing heat, and working precision of the graphene inductance element is prevented from being influenced by external impact.
