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.

A vehicle has an electric or hybrid-electric traction drive supported by an ungrounded vehicle frame. The vehicle also has a current collector, which can be electrically connected to the traction drive and which can be brought in galvanic contact with a contact line of a grounded contact-line system to supply traction energy. The vehicle contains an electrical protection system for avoiding dangerous contact voltages on the vehicle frame or on a vehicle part connected to the vehicle frame in a conductive manner. The protection system has a first protection stage, a second protection stage, and a switching element, by which the protection system can be switched between the first and the second protection stages. The first protection stage provides greater safety from dangerous contact voltages than the second protection stage. Thus, a protection system can be provided which provides sufficient safety in all operating states of the vehicle.

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.

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.
