Definitions

  • the invention relates to a transformer, in particular a medium-frequency transformer with galvanic isolation, as used for example for applications in the field of rail technology.
  • Transformers are essential components in electrical engineering, in industrial plant construction, in rail vehicle construction and in many areas of technology in general (including in aircraft and satellites). However, power compression in the design of transformers and chokes has historically been improved to a limited extent.
  • two-legged MF transformers for industrial and rail transport, are traditionally cooled only at the windings or at gaps with air or other media.
  • additional cooling surfaces or indirect liquid cooling devices for the windings and the magnetic circuits bring about a certain reduction of volume and weight, but no fundamental breakthrough.
  • the known MF transformers are arranged externally to the HBU or drive power converters.
  • HBUs are mostly cooled with air of rare water.
  • water cooling is used for drive converters, at least for the MF transformers.
  • recoolers are sometimes required, which require additional installation space in the underfloor area of the wagons or on the SR container.
  • the invention has for its object to provide a transformer, in particular a two-arm MF transformer with low volume and weight and similar design of about 40 to over 400 kVA.
  • the coil penetrations of the hermetically encapsulated primary and secondary windings with intermediate insulation, electrically and thermally separated from each other, the cores are thermally and dielectrically isolated and permanently secured and held gap-free within the coil penetrations over rib faces or corner surfaces.
  • two-arm transformer can therefore be compared to newer transformers achieved by a factor of 1.2 -1.5 times more favorable volume / power weight, the power category: 200-400 kVA not yet or only with large Expenses (water cooling, waveguides, etc.) could be built, which is important for traction, in rail transport, but also industrial applications.
  • the ribs or corner parts for the attachment of the cores are conical. This has, among other manufacturing reasons, since in this way only once split mold inserts for the coil penetrations are needed, which can be easily expressed after the Aushärtrind of the encapsulation.
  • the cores are glued to the ribs and / or corner support part surfaces, wherein the cores and yokes outside and / or in the region of the glued joints to the ribs or corner contact part surfaces of the encapsulation with thin insulation material, preferably GfK , "glued".
  • thin insulation material preferably GfK
  • the primary and secondary windings of the transformer are separated by intermediate insulation and the hermetic encapsulation voltage significantly oversized from each other, the cores are thermally and electrically decoupled held in corresponding Spulen matdringungen in Spulenumguß.
  • mechanical-metallic brackets, such as clamping profiles, fittings, etc. of conventional transformers even MF transformers for fixing the windings and the cores completely eliminated, which makes the MF transformer compared to conventional transformers particularly quiet and vibration proof (train / aircraft applications).
  • This "separation measure” further increases the surface of the transformers compared to the compact casting by about 25%, at the same time a further improvement, the “inner side ventilation" of the cores and yokes is achieved, which is another physical leap in quality towards optimal cooling of the cores and yokes means.
  • hermetic Spulenumgados realize u. a very reliable galvanic isolation between the primary and secondary windings, in all climatic conditions, including moisture / dirt. They form, with the windings, a compact block for receiving the cores, which is a problem with conventional MF transformers.
  • Non-hermetically encapsulated MF transformers which are still in numerous use, often fail after 4-5 years of operation because moisture and dirt have in the meantime created creepage paths, both between grounded cores and between primary and / or secondary windings there are rollovers at the non-isolated potential arc base points. As a rule, these transformers can not be repaired.
  • the potting resins are preferably epoxy resins with thermally conductive fillers, preferably aluminum oxide / nitride and / or silanized quartz powder and / or other isolated metal particles composed, as far as the casting insulation properties are not affected thereby.
  • thermally conductive fillers preferably aluminum oxide / nitride and / or silanized quartz powder and / or other isolated metal particles composed, as far as the casting insulation properties are not affected thereby.
  • the windings are preferably covered with fibers, especially glass fiber fabric.
  • the primary and secondary windings are preferably foil conductors, but may also be profile waveguides for direct or indirect liquid cooling. But also high frequency strands are used.
  • the transformer is - as already indicated - designed as a double-arm transformer, wherein a core / yoke pair is used for two windings of the transformer.
  • the core attachment is made inside the gate, i. inside the windings.
  • FIGS 1 to 4 show a first embodiment of the medium-frequency transformer according to the invention in different views.
  • the MF transformer has a Spulenumguß 1 with a substantially chamfered-rectangular cross section.
  • a primary winding 2a and a secondary winding 2b are cast. This results in a windings 2a, 2b hermetically enclosing block.
  • the front and the back form an end face 3, the z. B. for the Positioning of the terminals 13, 14 of the MF transformer can be used.
  • At the lower end transformer feet 4 are preferably provided which have a sprue fitting 6 for floor or wall mounts.
  • the coil encapsulation 1 for example, two three-layer windings 2a and 2b are inserted, wherein the windings are juxtaposed by a Isolier fundamentalguß 19 separated from each other. Further, 1 cavities 20 can be provided on the front and back 3 of the Spulenumgußes that provide better dissipation of heat from the coils 2a, 2b to the outside in the environment.
  • the electrical connection of the windings 2a and 2b takes place in integrated boarding rooms 11 and 12, which are also completely filled with potting compound.
  • each coil has a coil penetration 29, wherein the opposite surfaces of the coil penetration 29 are arranged plane-parallel to each other.
  • the coil penetrations have, for example, approximately rectangular cross-sections, with chamfered parts on the narrow sides of the penetrations, wherein in each case on one longitudinal side of the coil penetration 29 mutually parallel ribs 9 or corner surfaces 28 are provided.
  • the ribs 9 to the surfaces of the coil penetration are arranged plane-parallel.
  • the ribs 9 and 28 are preferably conically shaped longitudinally, both laterally and in their aperture width.
  • the cores 21, 22 and yokes 18, as indicated in FIGS. 7 and 8, are joined into assemblies from I-cores or ribbon cores.
  • the cores 21, 22 or yokes 18 are then externally and in the region of the adhesive joints to the ribs 9 of the Spulenumgußes 1 with a thermal insulating layer 5, preferably adhered GfK. This ensures that the cores 21, 22 can be thermally decoupled from the windings 2a, 2b.
  • These pasted with the insulating layer 5 cores 21, 22 are now attached to one side by gluing to the ribs 9.
  • the cores 21, 22 thus have contact only with the coil encapsulation 1 in the region of the ribs 9.
  • soft magnetic materials can also be used as magnetic components. This has the advantage that at low frequencies e.g. ⁇ 4000 Hz almost the full rated power of higher frequencies 7,500 - 15,000 Hz (with ferrite) can be maintained. Another big advantage is that with just a few coil cross sections at variable widths or heights, the entire power range of current and future SR transformers can be realized.
  • the primary and secondary terminals 13, 14 are preferably circularly insulated and arranged at 180 ° or laterally offset above and below.
  • vertical or horizontal chimneys or forced air ducts which are actively or passively flowed through by cooling air, remain through the remaining gaps 10 between the core and the coil encapsulation.
  • the cores 21, 22 are freely suspended in the windings on all sides and attached to the ribs 9 and / or in the corners 28 only on one side. As a result, the cores 21, 22 due to the adhesion "elastic-solid", noise-damping held in the Spulenumguß 1. All parts for fixing the cores 21, 22 are made of non-conductive materials, so that the cores can float freely in terms of potential. The cores are not grounded in contrast to conventional transformers. Preference is given to using ferrite cores or nanocrystalline or amorphous cores.
  • the transformer according to the invention opens with its small volume, size and low weight, for example, to be arranged directly in cooler currents different power converter or modules. Due to its hermetic construction, it also requires no further measures for mechanical or sealing protection against environmental influences.
  • Figures 5 and 6 show a slightly modified embodiment of an MF transformer according to the invention, in which case somewhat narrower ribs 9 are used for fastening the cores 21, 22.
  • the transformer can be optimized either with respect to its leakage inductance or its noise emission.
  • FIGS. 9 and 10 show, by way of example, a cross section and a plan view, respectively, of one of the two windings 2a and 2b.
  • the conductors are inter alia copper foil conductors 23, which are wound with the interposition of an intermediate insulation 24 substantially square or rectangular.
  • the Cu conductors 23 are externally connected in the terminals 13, 14 of the Spulenumgußes 1. All windings are firmly and hermetically sealed with a potting compound of a resin, preferably epoxy resin, with thermally conductive fillers.
  • the windings are further wrapped with a coarse mesh glass silk tape to allow the winding encapsulation highly stable, heat and cold shock resistant.
  • the conventional mica insulation is replaced according to the invention by thermal bridges 25 and casting resin cast intermediate insulations.
  • the magnetic cores are provided with thin GfK plates for stress compensation and as adhesion promoter. Furthermore, side recesses 16 remain for the air bubble rise to the middle or outside for the process improvement during the casting process of the windings.
  • FIGS. 11 to 14 show a transformer similar to that of FIGS. 1 to 4, identical components being provided with the same reference numerals.
  • two three-layer windings 2 a and 2 b are inserted here in the coil encapsulation 1, wherein the windings are electrically and thermally separated from one another next to each other by a central gap channel 27.
  • FIGS. 15 to 18 show a transformer similar to FIGS. 5 to 8, wherein identical components are provided with the same reference numerals.
  • the windings are hereby also electrically and thermally separated from one another by a center gap channel 27.
