    摘要： The present invention provides a method for transmitting the electric power data of a rail includes collecting electrical current analog signals from a conductor rail and transmitting the electrical current analog signals to a processing module; converting the electrical current analog signals into electrical current digital signals through the processing module; transmitting the electrical current digital signals to a monitoring platform through a wireless communication module. The electrical current information of the conductor rail is collected by an electric current sensor installed on a cable, which is connected to the conductor rail. The electrical current information collected by the electric current sensor is transmitted to the processing module after pre-processing comprising signal amplification and filtering. The present method effectively prevents problems of high bit error rates and faults with a negative impact on the data transmission with data message corrupted by noise during transmission.

    摘要： The invention relates to a voltage limiting device having a switching device 5 which has a movable switching contact 16 which can be moved between a closed position and an open position, an electrical conductor 10 electrically connecting a first cable terminal 11 to the switching device and an electrical conductor 12 electrically connecting a second cable terminal 13 to the switching device. The voltage limiting device according to the invention is characterised by a special arrangement and design of a conductor portion of one of the two electrical conductors 10, 12. A conductor portion 10B, 12B of an electrical conductor 10, 12 is arranged or designed in such a way that this conductor portion, together with the movable switching contact 16 of the switching device 5, forms an arrangement of conductors through which currents flow in opposite directions during operation of the switching device. As a result, electrodynamic forces act on the movable conductor and the fixed conductor and are directed in such a way that the conductors repel one another. The switching contacts therefore tend to close. The voltage limiting device can switch higher loads without the conductive parts having to be reinforced or other technical measures having to be undertaken.

    摘要： A conductor line for supplying an electric load movable on the conductor line in the longitudinal direction of the conductor line, includes at least one conductor strand which runs in the longitudinal direction and has an electrically conductive profiled conductor section for contacting a sliding contact of a current collector of the load and at least one elongated slotted waveguide, which runs in the longitudinal direction, with a longitudinal slot for receiving an antenna which can be moved together with the load. A related current collector and a conductor line system are also provided. The aim is to allow a compact and material-saving design with good fault-tolerant transmission. This is achieved by a conductor line in which the longitudinal slot is tilted by an angle which does not equal 90° about the longitudinal direction with respect to a movement plane on which the current collector can be moved, by a current collector in which the antenna or a part thereof is completely or partly tilted by an angle which also does not equal 90° about the longitudinal direction with respect to the movement plane, and by a conductor line system including such a conductor line and current collector.

    摘要： A short circuiting device for an electric railway system having a conductor rail for supplying electric power to drive the vehicles. The function of the device is to provide a short circuit between a track rail and the conductor rail. The short circuiting device contains a first contact element providing a face to make contact with the track rail and a contact arm that is coupled to the contact element via a jointed connection and has a contact face for making contact with the conductor rail. The jointed connection is a multi-hinged connecting facility containing two levers which are joined to each other via a knee-type joint and joined via the respective first and second connection hinges to the contact element and the contact arm. One of the levers is in the form of a closing lever and the shape and arrangement of the levers and hinged joints is such that by executing a rotational movement with the closing lever, and via this, movement of the knee-type joint about the axis of the connection hinge related to the closing lever, the contact element and the contact arm can be brought together thus making electrical contact.

    摘要： The invention relates to a switching device, in particular for a voltage limiting device, which has a first fixed switching contact 14 which is electrically connected to a first device terminal 8, a second fixed switching contact 15 which is electrically connected to a second device terminal 9, and a movable switching contact 16. The invention also relates to a voltage limiting device which has such a switching device 5. The first and second fixed switching contacts 14, 15 of the switching device are arranged next to one another in such a way that their contact surfaces 14A, 15A point in the same direction. The movable switching contact 16 can be moved between a closed position in which the first and second fixed switching contacts 14, 15 are electrically connected to one another, and an open position in which the first and second fixed switching contacts 14, 15 are separated from one another. The first and second fixed switching contacts 14, 15 and the movable switching contact 16 form an arrangement of electrical conductors which are arranged substantially parallel to one another. At least one of the fixed switching contacts 14, 15 has an elongated contact surface which extends in the direction A of current flow. Electrodynamic forces act on the fixed conductors 14, 15 and the movable conductor 16, which are directed in such a way that the conductors attract each other, i.e., the switching contacts tend to close.
