摘要： A system and a method for reducing stray current produced by power supply backflow for a subway walking rail, which is suitable for a power supply system of a rail backflow used by a direct-current power supply subway train. A parallel inductor, a super capacitor, an IGBT switch, a contactor, and the like are used to form a connection branch, and intelligently control the connection and flowing direction of a current, to effectively filter harmonic components of a backflow, so that leakage of harmonic components of a tray current produced by harmonic waves generated by an inverter switch circuit of the train to the outside of the walking rail can be effectively reduced, thereby preventing other facility devices from being harmed by electrochemical corrosion.

摘要： A shunt apparatus includes a mounting bracket assembly configured for connection to a vehicle, an actuator connected to the mounting bracket assembly, and a shoe unit connected to the actuator. The actuator is controllable to move the shoe unit to an extended position where a conductive shoe of the shoe unit is positioned to contact a conductive first running surface on which the vehicle travels. The shoe unit includes a resilient biasing assembly that is configured to exert a force on the shoe, to press the shoe against the running surface during movement of the vehicle. Two of the shunt apparatuses may be attached to opposite sides of the vehicle. The shoes of the two shunt apparatuses are electrically connected to one another by an electrical cable. When the shoes are brought into contact with respective running surfaces, the running surfaces are electrically shunted for vehicle signaling purposes or otherwise.

摘要： A railway transportation power supply construction, comprising a power supply rail (1) and a return current rail (2) respectively secured on two sides of an insulating base (3) and isolated by the insulating base (3). A power supply arm (6) and a return current arm (7) are mounted to a bogie (12) of a vehicle (9) and insulated from the vehicle body by means of insulation rings (8), and the bogie is provided with a drive mechanism (10). The power supply arm (6) has a front end connected to one end of an input port of the drive mechanism (10), and a terminal end in contact with the power supply rail (1). The return current arm (7) has a front end connected to the other end of the input port of the drive mechanism (10), and a terminal end in contact with the return current rail (2). During operation of the vehicle, the power supply arm (6) has friction with the power supply rail (1) to be powered, and the return current arm (7) has friction with the return current rail (2), thus enabling the vehicle (9) to travel through a junction section with uninterrupted power supply while the structure and operating condition of a junction remain unchanged. The construction can be used to modify existing urban rail transit systems, such as a subway or light rail system, or electrification railway systems, and also be used in building new railway lines.

摘要： A clamp for providing the electrical connection of a cable to a rail, particularly for short-circuiting a railroad power line during maintenance work, comprising a supporting element (2) provided with two jaws (3, 4) which can engage, on mutually opposite sides with respect to the web (10) of the rail (8), the fishing planes (5, 6) of the upper portion or head (7) of the rail (8). The supporting element (2) has, between the two jaws (3, 4), a clamping element (11) movable along an action axis which is substantially perpendicular to the rolling surface of the rail (8) in order to act on the rolling surface of the rail and apply to the jaws (3, 4), engaged with the corresponding fishing planes of the head of the rail, an upward traction. The two jaws (3, 4) are pivoted to the supporting element (2) about two mutually parallel pivoting axes arranged laterally to the action axis of the clamping element; the pivoting axis (13, 14) of one jaw and the portion of the same jaw that can engage the corresponding fishing plane of the head of the rail are arranged laterally, on mutually opposite sides, with respect to the action axis of the clamping element.

inserting the stub (1) in a die (10) of a press,
performing a cold deformation to form a flanged head at the end of an internally hollow stem (21), and
extracting the resulting electrical contact (30) from the die.

摘要： An electrical connector is disclosed with an expanding dowel pin for fastening onto a metal support. The electrical connector includes a dowel pin body (A) of stepped tubular shape, which may be inserted in the bore of the rail and bear against the rail at the shoulder of the step. A threaded stud (B) including a taper (7) interacts with the bore (11) of the dowel pin body locally to expand the dowel pin body radially in the bore (3) of the rail (2). A nut (9) on the threaded end of the stud (B) axially draws the stud to achieve such expansion when tightened. A conductor (10) is joined to the dowel pin by overmolding (12) of a metal alloy which is preferably melted and cast in the factory, enveloping the end of the conductor and part of the dowel pin body and yet spaced some distance from the end bearing faces of the dowel pin body.
