Definitions

  • the invention relates to a throttle assembly for a converter device according to the preamble of claim 1.
  • the invention can be used, for example, for construction used by converters for trams.
  • DE 43 38 277 A1 describes a liquid-cooled converter module with at least one a power semiconductor that can be switched off and one of several components, such as capacitor, choke and diode existing circuit for the switchable Power semiconductors (GTO) known. All essential components are included the wiring on a single, as a cast or die-cast part from one high-quality insulating material, such as epoxy resin or polyester resin Insulated subrack arranged.
  • the insulating subrack is with an integrated electrical power current path railing for electrical connection the wiring components and with electrical connections for contacting the wiring components.
  • To build the converter device is to integrate the insulating subrack in a housing.
  • the invention has for its object a throttle assembly for a power converter device of the type mentioned at the outset, which can be easily achieved with the the converter valves and the semiconductor cooler-containing valve assembly and with which overall considerable savings can be made Space requirements, weight and costs are achieved.
  • the advantages that can be achieved with the invention are in particular that with the help of the proposed throttle assembly, a very high assembly and device compression When designing a converter device, what material savings is achieved as well as weight, volume and cost reductions Has.
  • the throttle assembly is absolutely insensitive to moisture and dirt as well designed vibration-proof so that it can be used under the toughest conditions is.
  • FIG. 1 shows a section through a side face of a throttle assembly 1 (Filter choke) for a converter device.
  • a throttle assembly 1 Fanter choke
  • An air gap 6 is formed between the side yoke 5 and the inner core / outer core 2/3.
  • a large number of individual spirals arranged in parallel next to each other wound disc coils 8 wind around the inner core 2.
  • the outer core 3 is in terms of of the cross section flatter and wider than the inner core 2 (at same cross-sectional area), since he also the disc coils 8 and thus a covers larger area.
  • the disc coils 8 are themselves preferably realized as an aluminum flat winding (foil or stranded conductor). This Design is optimal with regard to the reduced space requirement.
  • the mechanical strength - in particular vibration resistance - of the throttle assembly 1 is ensured by an insulating potting 9 (preferably cast resin), which Inner core 2, outer core 3, side yokes, 4, 5 and disc coils 8 and encloses in addition, the air gaps 6, 7 realized as solid air gaps.
  • an insulating potting 9 preferably cast resin
  • the disc coils - ensuring thermal energy produced are the tops the disc coils 8 free of insulating potting 9.
  • the electrical insulation and the Heat transfer to the outside takes place via a massive heat dissipation plate 10 - consisting of a material with good thermal conductivity and good electrical Isolation ability, such as preferably ceramic (for example aluminum oxide or Aluminum nitrite) -, which rests directly on solid profiles 24 of the disc coils 8 and the heat transfer to an external cooler, for example the bottom of the semiconductor cooler of the valve assembly 18 shown in FIG. 3.
  • the electrical connections between the disc coils i.e. the respective ends of the individual coils partly in the form of solid profiles 24 with a rectangular shape or square profile, which are widened, a large cross section have and are in intensive contact with the heat dissipation plate 10, so that - taking into account the distances required for electrical insulation - almost the entire surface of the heat dissipation plate for thermal pressure contacting is exploited.
  • the electrical conductors of the disc coils 8 serve at the same time the heat conduction, the beginning and end of each disc coil the resulting Heat loss via the solid profiles 24 and the heat dissipation plate 10 to the cooler derives.
  • the disc coil connector for the electrical connection of the windings Adjacent disc coils are marked with number 25.
  • the throttle assembly 1 has in addition to its actual function as an inductive electrical Component has additional functions and carries additional components, which are important for the operation of the converter device, in particular an input circuit with fuse and switching element .. This saves one separate clipboard for the input connections of the converter device.
  • An electrical connection 11 is used to connect the throttle assembly with another assembly of the Converter device, preferably with a capacitor assembly shown in Fig. 3 19th
  • the throttle assembly 1 is used for mechanical protection against external influences surrounded by a preferably metallic housing 17, which with corresponding Breakthroughs for the heat sink 10, the components of the input circuit and the electrical connections are provided.
  • Isoliervergusses 9 is the complete input circuit of the converter device several modules 13 to 16 arranged side by side, namely an electrical connection with fuse holder 13 including fuse and fuse indicator, a connecting part 14, the switching element 15 included Switching chamber and magnetic driver and a drive 16 for the switching element 15.
  • the integration of the input circuit eliminates the converter device 20 in the throttle assembly 1 advantageous otherwise usual separate converter clipboard, the fuse and switching chamber holder and especially the weight-intensive cabling for these modules.
  • Via busbars integrated within the insulating encapsulation 9 result in electrically conductive connection paths from the electrical connection 13 with fuse, on to the switching element 15 and over the electrical connection 12 to the disc coils 8 and from there to the external accessible electrical connection 11.
  • the housing 17 has a plurality Provide threaded holes 21.
  • the Converter device 20 is composed of three main groups, namely one central valve assembly 18 with the semiconductor components and the cooler, the Throttle assembly 1 and the capacitor assembly described above in detail 19. Both the throttle assembly 1 and the capacitor assembly 19 use to dissipate the thermal energy produced in their components advantageously the cooler of the valve assembly 18.
  • valve assembly 18 and throttle assembly 1 The mechanical connection between valve assembly 18 and throttle assembly 1 is carried out by means of bolts 22, which are in the aforementioned threaded holes 21 intervene.
  • Disc springs 23 between the mounting flange Valve assembly 18 and the bolt 22 provide the optimal heat transfer required contact force between the flat ground heat dissipation plate 10 and the radiator of the valve assembly.
