摘要： Magnetic or electromagnetic field generators are disposed on, near or toward opposite sides of a roadway, carriageway or lane such that magnetic or electromagnetic lines of force across at least a portion of the roadway, carriageway or lane. A vehicle traveling down the roadway, carriageway or lane interacts with the magnetic or electromagnetic lines of force to absorb energy that can be used for battery recharging or other purposes. Magnetic or electromagnetic flux density can be increased by embedding magnetic materials or additional structures in the top paving course forming the roadway, carriageway or lane.

摘要： Disclosed is an optimized energy interconnection system for an urban railway train in the technical field of urban railway transportation power supply, for addressing the technical problem that distribution of regenerative braking energy flows cannot be accurately determined. The system includes a DC intermediate bus and a multi-port flow controllable energy router. The multi-port flow controllable energy router can comprehensively control a source and a load connected in parallel on the DC intermediate bus and thus can accurately determine the distribution of regenerative braking energy flows, thereby forming a well-developed system for evaluating usage of the braking energy.

摘要： The present invention provides an improved catenary wire system for an overhead line equipment (OLE) installation. Known OLE installations are prone to sagging and hence require a large number of support structures, which are expensive to install and maintain. These structures also appear “cluttered” and ungainly. The catenary wire system of the present invention comprises a fibre reinforced composite catenary wire configured to suspend a contact wire; and at least one elongate electrically conductive element arranged generally parallel with the catenary wire. It has been found that the catenary wire system of the present invention is able to withstand increased tensions when compared to known OLE installations, which reduces the amount of catenary wire sag, and can thereby reduce the number of support structures required by an OLE installation.

摘要： In one or more embodiments, techniques are provided for modeling overhead line structures of electric railways that utilize a flexible, reusable structure template to automatically generate a 3D model of the overhead line structure. Each structure template includes a set of points that represent joints of the overhead line structure and components that represent elements of the overhead line structure. A feature definition of each joint and component includes properties, constraints and cell mappings. By mapping key points of reference lines for an overhead line structure to key points in an applicable structure templet for the overhead line structure, and applying the constraints and, in some cases the cell mappings, a 3D model of the overhead line structure is automatically generated. The 3D model may be a “low detail” stick representation for fast modeling, or, using the cell mappings, a “high detail” cell-based representation for very realistic modeling.

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 for supplying power to railway operating elements that are arranged along a railway line. A terminal station has a power supply device. At least one substation has a power supply subunit for at least one connected railway operating element. An input-side control unit of the substation modifies the current consumption in the substation incrementally, with corresponding modification of the voltage of the power supply subunit to match the rated voltage of the railway operating element on the substation, and producing a coded message. The control device of the terminal station modifies the output voltage according to the coded message, until the rated voltage for the railway operating element is reached on the power supply subunit. When the nominal voltage is reached the power supply subunit is connected to the railway operating element.
