摘要： A method for producing a current conducting device, a junction box for a vehicle battery, and a motor vehicle having a corresponding junction box. In the method, multiple busbars are positioned in a predetermined location in relation to one another and then enclosed using an electrically insulating plastic cladding. In this case, a respective opening of the plastic cladding is left open in a respective connection region, in each of which at least two of the busbars meet one another. The busbars are then welded to one another in a respective region of the opening.

摘要： A method and an arrangement are provided for inductive positioning of a current collector on a vehicle relative to a stationary current conductor. The method involves transmitting a signal having predetermined phase characteristics using a signal transmitter arranged along the longitudinal direction of the current conductor; detecting the transmitted signal using a signal receiver on the vehicle, which signal receiver comprises at least one vertical antenna; detecting the phase characteristics of the signal induced in the at least one vertical antenna, indicating the relative location of the vertical antenna and the signal transmitter in the transverse direction of the vehicle; and controlling a positioning arrangement in dependence of the received signals.

摘要： A system for supplying power to a trolley chain. The system includes: a trolley chain, consisting of at least two trollies coupled with one another, wherein the trolley chain has a closed bus; and a stationary energy conductor along the track of the trolley chain. The stationary energy conductor consists of one or more successive segments, which are spaced apart from each other. The closed bus has several transmission heads, which are designed to supply the closed bus with electricity from the stationary energy conductor without contacting the stationary energy conductor, if they are within a pre-determined distance to the stationary energy conductor. During a journey of the trolley chain along the track, at each moment in time, at least one of the transmission heads supplies the closed bus with electricity from the stationary energy conductor.

摘要： Disclosed is a rail supporting assembly for supporting a contact rail of a railway system that includes a base, a rail support head positioned relative to the base, and a support member comprising a dielectric phenolic material coupled to and positioned between the rail support head and the base to thereby support and insulate the contact rail. The support member includes a fracture area to facilitate fracturing of a sidewall of the support member when a fracturing force, such as a electrical arc event, is applied to the support member. The support member preferably is coated with a varnish to prevent absorption of water by the support member.

摘要： The shoe derailment device for use in derailing a conductor shoe assembly of a bridge crane from a conductor rail assembly generally has a wedge head provided at a longitudinal end of a body made of an electrically insulating material, the shoe derailment device being securable to the conductor rail assembly in a derailment position in which the shoe derailment device is positioned outside an operating zone of the bridge crane, with the wedge head facing the operating zone in a manner that if the conductor shoe assembly is moved outside the operating zone, into the area occupied by the shoe derailment device, the conductor shoe assembly is derailed from the conductor rail assembly as the conductor shoe assembly engages the wedge head and is maintained in a derailed state by the electrically insulating material when the conductor shoe assembly is engaged with the body.
