Definitions

  • the invention relates to a device and a method for the supply of Track brakes of a drainage system on a marshalling yard with electrical energy.
  • the shunting of individual wagons or groups of wagons in centralized shunting yards is a common production method in rail-bound freight traffic. At these shunting yards incoming trains are disbanded and new trains are formed. To speed up the operations and to reduce production costs, the majority of such Rangierbahnhöfe usually has a called "runoff" artificial survey on the individual cars or groups of cars to be resolved freight train are pressed. Under the influence of gravity, these vehicles forced over the mountain then pass through a distribution zone consisting of a plurality of successive point connections, whereby they are fed to a predefined directional track, in which the individual wagons or groups of wagons to be assembled into a new train are collected.
  • the speed of the running over the mountain vehicles to a planned for a proper and effective filling of each directional target Adjust speed and thus prevent in particular a run on other already located in the direction track rail vehicles with an impermissibly high speed.
  • the number, the location and the exact brake design of these rail brakes depends on the particular on-site conditions (in particular height and inclination of the Albanyberg as well as inclination and usable length of the direction tracks).
  • the aim is that on the one hand, the worst-moving car can reach the furthest from the top of the professionberges target, on the other hand, even the best-running car can be braked even with a full directional track with certainty to a permissible flow rate.
  • the directional tracks can be equipped with additional slope compensation brakes.
  • Electrodynamic rail brakes (EDG) are often used for the directional track brakes or slope compensation brakes.
  • an electrodynamic rail brake in which a magnetic field is induced in such a way in both sides of a rail track arranged brake carrier by means of an electric current flow, that an attraction force between these brake carriers is constructed. By this attraction, the brake carriers attract each other and thereby form a brake groove having a preset light mass. Now rolls the wheel of an expiring rail vehicle through this brake groove, it must press the brake carrier against the magnetically generated force apart to Radsammlung Museum.
  • Each electrodynamic rail brake must have a power supply with a depending on the maximum value of the rail brake to be provided Braking work designed electrical connection value.
  • electrodynamic Track brakes of usual size with a brake length of 20 m and a throughput of 25,000 ampere turns (Awdg)
  • connection values more than 200 kVA required.
  • Relative to a complete Rangierstrom with a variety of such electrodynamic rail brakes and taking into account a simultaneity factor prescribed by the plant operator, depending on the size of the system up to three track brakes at the same time their maximum braking effort must be able to perform, adds up to be provided electrical connection value to over 600 kVA.
  • UPS uninterruptible power supply
  • the invention is therefore based on the object, an apparatus and a method for the supply of track brakes of a drainage system on a marshalling yard to provide with electrical energy, by means of which the electrical Connection characteristic of such, a jumbled use underlying facilities smoothed out and the plants with smaller and better exploited over time Connected to power distribution networks are designed to be connected.
  • the costly and complex equipment for uninterruptible power supply simplified or substituted become.
  • this object is achieved in conjunction with the preamble of Claim 1 solved by at least one capacitor for storage and providing electrical energy to the or each rail brake is.
  • the energy consumption of a braking work performing track brake time from the removal of electrical energy is decoupled from a power grid.
  • the individual punctual Consumption peaks can be caused by the supply network by a continuous Charging process can be covered with lower electrical power.
  • the charge stored in the capacitor makes the operation of the track brake regardless of the current at the time of the track brake current Voltage state of the supply network.
  • the track brake remains in case of failure of the supply network for the braking work on at least the Time of the voltage drop already over the expired mountain and not yet arrived in the direction track car ready.
  • a separate Device for uninterruptible power supply is powered by the active Integration of a capacitor in the power supply superfluous.
  • the or each rail brake with at least one of these rail brakes associated capacitor electrically connected is. This will allow for every single rail brake on a arranged in their immediate spatial environment condenser can access. In this way, the cabling effort can be effectively reduced be bridged as between energy storage and consumer only short distances Need to become. This is especially with regard to the elaborate, with low cable resistance to be carried cable runs between capacitor and consumers of importance.
  • the invention further provides that the or each rail brake having a current regulator in one through the or each capacitor fed DC link is fed.
  • the capacitors due to the elimination of an involvement of chemical Conversion processes at the storage capacity a much more dynamic Behavior regarding their charging and discharging capacity and their low internal resistance on.
  • a UPS in online bypass operation waived which also makes the power losses caused by these components effective be avoided.
  • the inventive concept is a plurality of each of the individual track brakes of Rangierablaufstrom associated capacitors electrically connected to each other via a ring line. It is particularly advantageous if the one another via a loop electrically connected capacitors arranged in parallel are. In this way, all capacitors connected to the loop form one as an alliance for all track brakes of the marshalling yard effective energy storage.
  • the capacity of the or each capacitor is designed in accordance with the average demand for electrical energy for controlling the or each connected track brake.
  • the total capacity of the arranged in parallel circuit capacitors of a loop according to the demand for electrical energy of a predetermined minimum number of simultaneously each of the maximum braking work-making rail brakes is designed. In this way, it is possible that the capacitors do not have to be dimensioned to the maximum required peak demand values of their respectively associated track brakes out, but only have to meet an average average power value with average braking work. The additional power requirement is provided by the remaining capacitors integrated into the ring circuit.
  • a charge controller ensures the continuous recharging of all existing in the inventive device memory capacitors.
  • the composite storage is sized large enough to meet the requirements of the plant operator with regard to a simultaneous operation of multiple rail brakes under full load. Regardless of the number of track brakes connected, both the desired reduction in the grid connection power and the more uniform load on the electrical supply network are thus effectively supported.
  • FIG. 1 shows the device according to the invention for power supply and power storage for a single electrodynamic track brake (EDG) (4).
  • the electrodynamic rail brake is shown in a schematic plan view.
  • the device comprises a charging current regulator (1) which draws the electrical energy from a supply network designed as an IT network.
  • IT network In such an IT network, all active parts of the earth are isolated or grounded through an impedance; Bodies are grounded directly independent of the ground of the power source.
  • the characteristic in the form of an IT network is chosen so that it does not lead to the failure of the track brake as a result of a short circuit occurring in the earthed network. For the monitoring and signaling of such ground faults, a separate ground fault measuring device is provided.
  • the charge current regulator (1) converts this alternating current into a direct current, by means of which the capacitor store (2) is charged.
  • the voltage of this charging DC current for the capacitor can thereby call between a nominal voltage U and a maximum value U max is varied in Abheksigikeit of different charging regimes.
  • a charging regime is desirable in which the capacitor is charged with the lowest possible voltage value U nenn over time-extended cycles.
  • the end-of-charge voltage U max is reached when the current consumption is lower than the set charging current.
  • the condenser memory (2) gives, if necessary, energy to a current regulator (3).
  • the current regulator acts on the induction windings in the electrodynamic track brake.
  • each track brake (EDG 1 ... EDG n ) has a respective arrangement of capacitor store (2) and current regulator (3) allocated in its closer spatial environment and wired to it, as already known per se from FIG is.
  • the individual capacitors are electrically connected together as a parallel connection in a ring line (5). In this way, on the one hand on the consumer side, a decentralized structure of energy storage and power sources at the same time but also the power connection side created a central structure for electricity from a supply network.
  • power is drawn from the decentralized capacitor storage units in each case in the ring main. The power supply is decoupled from such load peaks and ensures by means of a constant power consumption for a continuous recharging of the capacitors connected in the loop.
