Definitions

  • the invention relates to a transformer, in particular cast-resin transformer, with at least one low-voltage winding and at least one high-voltage winding.
  • the DE 89 14 262.4 U1 writes a transformer with shield windings between the primary and undervoltage windings.
  • a shield as isolated, electric not closed winding of a magnetizable material selected. To prevent a short circuit in the electrical shield, there must be no closed winding.
  • US 4 176 334 A discloses a transformer with a low voltage coil around which an electrical shield is disposed. This shield is electrically connected to the undervoltage coil. Around the shield around the high-voltage coil is arranged.
  • the high voltage coil has a shield consisting of an inner shield and an outer shield. Both the inner and the outer shield of the high voltage coil are electrically connected to the high voltage coil. This shield serves to shield the windings of the high voltage coil from external fields.
  • a disadvantage of all previous transformers, especially cast resin transformers, of the prior art is the need for a complex protective housing or an external protection around the transformer in an outdoor installation.
  • a protective housing is also necessary when installing the transformer in climatically unfavorable or heavily polluted environments.
  • this protective housing is also necessary to prevent the person from touching the transformer.
  • the distance between the outer protective housing and the outside of the transformer according to the prior art is sufficient great to choose. Due to this disadvantage, larger footprints than necessary for the operation of a transformer must be provided.
  • Object of the present invention is therefore to provide an easy to manufacture, compact transformer that is finger-safe.
  • an electrical shield is arranged around the high-voltage winding.
  • the high voltage winding is in particular a medium or high voltage winding.
  • the voltage potential between the coil surface and the - possibly high voltage leading - high-voltage winding is set to zero in an advantageous manner and thus prevents a flashover, even in the event of contact by a person.
  • the electrical shield encloses the High-voltage winding up to the electrical supply and discharge almost completely.
  • the electrical shield is connected to the electrical ground and thus grounded. Grounding the electrical shield minimizes or prevents a person touching, electrically shielding the electrical shield.
  • the electrical shield encloses the cylindrical high-voltage winding coaxially, wherein the electrical shield is interrupted in the radial direction. The resulting gap isolates the ends of the electrical shield in the radial direction against each other.
  • the ends of the shield must overlap, this advantageous embodiment of the electrical shield short-circuit currents are prevented within the electrical shield.
  • insulation in the space may prevent electrical connection of the electrical shield ends thus created.
  • the ends of the electrical shield overlap to ensure complete shielding. In the overlapping area, an insulation, ideally a thin insulating film, can be introduced to avoid short-circuit currents.
  • the electrical shield is an electrically conductive material, such as a wire mesh, and thus represents a Faraday cage.
  • the transformer is configured so that the distance between the gap between the electrical shield and the high-voltage winding is selected in that, depending on the dielectric located in the space between the electrical shield and the primary winding, the voltage breakdown is assured given is.
  • the distance of the shield to the high-voltage winding should be selected so that a voltage breakdown on the casting resin located in the gap is excluded. In an analogous manner, this distance is to be selected for other insulation materials.
  • the electrical shield against external contact influences is to be protected. This can be ensured in the simplest case by an outer plate. Also, by casting a transformer with cast resin - a so-called "casting" - given the possibility that the casting encloses the electrical shield and a distance between the outer wall of the casting and the electrical shield remains. Due to the common potting of the high voltage winding and the electrical shield partial discharges are significantly reduced, since the gap high-voltage winding / shield is not filled with air. At the same time, the common potting increases the dimensional stability of the electrical shield and ensures a constant distance between the high-voltage winding and the electrical shield.
  • the high-voltage winding with the electrical shield, and the lower voltage winding is cast together with casting resin.
  • the transformer has at least one guide for the electrical connections of the high-voltage winding and / or the low-voltage winding located inside the transformer, wherein the guide is connected to a bushing arranged on the outer wall of the transformer. Due to this all-round electrical shielding and grounding of the outer transformer shell, a complete electrical shielding and thus a contact safety for people is given. Furthermore, this given for cast resin transformers possibility of installation of the transformer in dirt prone or climatically unfavorable environments is also given for the transformer according to the invention.
  • the bushing and / or the mounting flange are connected to the electrical shield and thus to the ground.
  • the transformer consists of at least two castings, wherein in each casting a high-voltage winding with shield, a low-voltage winding are shed together.
  • the castings thus produced are arranged around a common core, wherein the high-voltage windings and / or the respective electrical shields and / or the low-voltage windings are interconnected by means of plug / connector and high-voltage cables in each case.
  • plug / connector and high-voltage cables in each case.
  • the so-designed transformer is cooled by an air and / or water cooling in the space between the high-voltage winding and the low-voltage winding.
  • fans are arranged in a suitable manner.
  • the fan prevents heat accumulation within the cooling channels and thus damage to the transformer.
  • the use of an external heat exchange device is possible. This embodiment of the invention is particularly suitable for installation on ships.
  • FIG. 1 shows a partial perspective sectional view of the transformer 1 according to the invention with two electrically connected high voltage windings 3a, 3b and two lower voltage windings 2a, 2b, wherein the high voltage windings 3a, 3b coaxially surround the lower voltage windings 2a, 2b.
  • the low-voltage windings 2 a, 2 b each have electrical connections 9, wherein a guide 8, the Konekttechnik the electrical connections 9 outside the transformer 1 by means of a passage 10 allowed.
  • an electrical shield 4a, 4b is arranged, which is connected to the electrical ground 11.
  • the electrical shield 4a, 4b encloses in the axial direction, the high-voltage windings 3a, 3b each almost completely.
  • no implementation 10 is shown for reasons of clarity.
  • the figure Fig. 2 is a sectional view through the perspective view of the figure Fig. 1 along the line II.
  • the low-voltage windings 2a, 2b are connected via electrical connections 9 within the guide 8 with the located on the outer wall of the transformer 1 implementation 10, such as made by the company Elastimold ® connected.
  • the bushing 10 is arranged on the outer wall of the transformer 1, this being the electrical shield 4a, 4b in the present example.
  • the mounting flange 10 is electrically connected to the electrical shield 4a, 4b and electrically grounded by the electrical connection to the ground 11.
  • the distance 5 between the lower voltage windings 2a, 2b and the high-voltage windings 3a, 3b is usable as a cooling passage.
  • a transformer 1 designed according to the invention allows, in spite of the line designs on the outside of the transformer 1 according to the invention, the set-up, which is prone to dirt, in dirt or climatically unfavorable environments for cast-resin transformers.
  • the use of a two-sided protective bushings 10 on the outer wall of the transformer 1 prevents the ingress of dirt.
  • FIG. 3 shows a partial perspective sectional view of the transformer 1 according to the invention with an electrically shielded high-voltage winding 3a and a lower voltage winding 2a, wherein the high-voltage winding 3a, the lower voltage winding 2a coaxially encloses.
