Current collector for e.g. tram vehicle, has conductor connected to current supply, where heat treatment arises in contact area and movement of contact point is provided along conductor/ contact area for distribution of heat in vehicle

摘要

The collector has a contact surface pressed against a conductor for supply of current under production of an electrical contact. The conductor is connected to an electrical current supply, where heat treatment arises in the contact area and the supply of current takes place over the area. The movement of a contact point (13) is provided along the conductor or along the contact area for the distribution of heat in a standing vehicle.
