  • the invention relates to an arrangement for a traction power supply with a power converter and a method for operating the arrangement.
  • a traction power supply with AC voltage switching systems are usually provided, which connect a serving for energy supply AC voltage network by means of a static frequency converter to an AC voltage network other frequency.
  • a rectifier is used instead of an inverter.
  • the connection and disconnection of a load or the shutdown in the event of a fault occurs by means of circuit breakers, which can switch off currents with appropriate design of the circuit breaker within about 15 ms. Short circuits are a common type of fault.
  • disconnectors are used, which make a disconnection path for safe shutdown after opening a circuit breaker.
  • DC currents can turn off particularly quickly and safely, while at the same time causing only low energy losses.
  • This is achieved by using two switching branches connected in parallel: a first branch has a load switch with semiconductor technology and an ultrafast disconnect switch, while a second branch has a plurality of semiconductor switching devices each having arrestor banks (barriers) connected in parallel. If a short circuit occurs, the diverter switch in the first branch interrupts the flow of current and the ultra-fast disconnector opens; Subsequently, by means arranged in the second branch semiconductor switching devices a secure
  • the object of the invention is to provide an arrangement for a traction power supply which can be manufactured comparatively inexpensively and safely, reliably, with low maintenance and with high availability during operation of the traction power supply.
  • the invention achieves this object by an arrangement for a traction power supply with a power converter, characterized in that the power converter is suitable for lowering its output voltage to a predefined voltage level in the event of a fault.
  • a power converter that is suitable, its output voltage in case of failure to a predetermined voltage level lower this lowering also during an operational shutdown eg for maintenance purposes. Accordingly, an inventive converter can just as quickly raise its output voltage to the intended operating level in response to a corresponding signal.
  • Such a power converter can limit the current within a few microseconds from the occurrence of a short circuit or even almost completely extinguished. This can be used to replace the previously common circuit breakers with fast disconnectors. If a short circuit occurs, the current from the converter is set to zero.
  • a short circuit can be conventionally recognized by a railroad protection device, such as a protective relay, which transmits the command to switch off the affected supply section to a control device of the power converter. After lowering the output voltage, the circuit breaker of the faulty section is normally opened. Thereafter, the current is increased by the controller back to the normal operating state to supply the functional lines again.
  • the power switch technology sets limits on the usable voltage in the DC rail power supply. This is in the solution according to the invention offers the opportunity to exceed today's voltage limits, not the case, since the shutdown of the short-circuit currents no longer must be done by circuit breakers.
  • a switch-disconnector can be used.
  • the output voltage of the converter is quickly adjusted in the event of a fault so that even in the event of a short circuit, only the rated voltage and the rated current of the traction power supply are present.
  • the switch-disconnector disconnects the feeder section affected by the fault, but during this process the other faulty feeder sections can continue to be supplied.
  • the power converter is connected on the input side to a three-phase alternating voltage supply, wherein the power converter has a parallel-connected current branch for each phase.
  • the power converter is connected on the input side to a single-phase AC voltage supply. This is an advantage because it is technically particularly easy to implement when connecting a single-phase AC power supply. In a single-phase AC power supply, the power converter consequently also has only one current branch.
  • each current branch has a plurality of semiconductor switching devices connected in series.
  • a single semiconductor switching device is not voltage resistant enough for a shutdown of the rated voltage.
  • several semiconductor switching devices meet this requirement.
  • Numerous semiconductor switching devices are provided, with the aid of which a frequency change of the alternating voltage frequency from the frequency of the supply network to the frequency of the traction power supply is carried out. In a traction power supply with DC voltage is regulated to a frequency of zero Hz.
  • the AC voltage supply is connected in each branch, that the branch is connected on the one hand via at least one semiconductor switching device to a return line and on the other hand via at least one semiconductor switching device to an output line.
  • the return line is often set to ground potential.
  • At least one disconnecting switch which is suitable for switching off a current flow at the predetermined voltage level, is arranged downstream of the converter on the output side. This is an advantage because it can be dispensed with a circuit breaker.
  • the at least one disconnect switch is a load disconnect switch which is suitable for switching off a current flow with the rated voltage of the traction current supply as a predetermined voltage level.
  • the at least one disconnecting switch is a disconnecting switch which is suitable for switching currentless at a predetermined voltage level of zero volts. This is an advantage because in the event of a fault, the entire downstream traction power supply is switched off for a short time, which is particularly safe. Using a power disconnect switch disconnects the voltage from the power converter to zero.
  • the disconnecting switch is a fast disconnecting switch which has an acceleration mechanism for rapid production of an isolating distance. This is an advantage because it must be ensured for interruption-free operation of the traction power supply that a shutting down of a short circuit occurs safely within fractions of a second, preferably in the millisecond range of less than 50 ms.
  • the acceleration mechanism has a spring for generating a spring tension. This is an advantage because by means of a preloaded spring, which has been biased by a motor, for example, a safe shutdown can be achieved in the event of a short circuit in fractions of a second by forming a sufficient separation distance.
  • at least one disconnecting switch is followed by a feed section of a contact line.
  • additional circuit breakers are additionally provided, each of which is followed by a further feed section of the catenary. This is an advantage because in this way one feed section can be switched independently of all other feed sections.
  • a control device for controlling the power converter is provided.
  • the control device is usually already provided in a power converter to set the frequency of the output voltage, in particular in modern, modular power converters.
  • This control device can be upgraded by adapting software and possibly hardware to a shutdown of the output voltage or to allow a lowering of the output voltage in case of failure.
  • a circuit breaker control device which is suitable, in the event of a fault, to switch off the supply section affected by the fault by opening the disconnecting switch provided for this supply section.
  • the circuit breaker control device monitors in particular in a switchgear with several circuit breakers their position, the switching position and readiness for switching - possibly the spring preload of the acceleration mechanism. If an error occurs, the circuit breaker control device is instructed by a protective device to open the relevant disconnector.
  • the power converter is a static frequency rectifier. This is an advantage because static frequency converters are widely used and proven in traction power supply.
  • the power converter is suitable for providing a DC voltage as the output voltage.
  • the power converter is suitable for providing a single-phase AC voltage as the output voltage.
  • the invention solves this problem by a method according to claim 13.
  • a preferred embodiment of the method according to the invention results from the dependent claim 14. It follows for the method according to claim 13 and the dependent claim 14, mutatis mutandis, the same advantages as explained above for the inventive arrangement.
