Definitions

  • a power supply with such a transformer is for example from the document WO 00/25327 A1 known.
  • the first and second polygons are isosceles triangles.
  • cylinder in this application is not limited to a straight circular cylinder, which is often associated exclusively with the term cylinder.
  • a cylinder is bounded by two parallel, flat surfaces (top and top surfaces) and a lateral or cylindrical surface formed by parallel straight lines. That is, it results from shifting a flat surface or curve along a straight line that is not in that plane. If the straight lines are perpendicular to the ground and top surfaces, the general definition for a straight cylinder is used.
  • the transformer described in said document is suitable and arranged for the transmission of electrical energy from a primary three-phase AC system to a secondary AC three-phase system or vice versa. It has a compact design, which is particularly advantageous for applications that require a small footprint.
  • AEG Power Solutions B.V. power supply arrangements are known which are particularly suitable and adapted for the supply of polysilicon reactors operated for the vapor deposition (CVD) of silicon from trichlorosilane to silicon bars according to the Siemens method.
  • the power supplies described therein provide secondary, i. on the reactor side at least temporarily high currents of 1000 to 5000 A, in particular of 3000 A, which flow through silicon rods to heat them.
  • power regulators are arranged in switchgear cabinets which are installed in one or two rows adjacent to a transformer of the power supply arrangement.
  • the arrangement can lead to long cable paths on the secondary side of the transformers.
  • Each of the pamphlets CN 102 290 211 A and CN 202 159 558 U discloses a power supply arrangement according to the preamble of claim 1, wherein the terminals of the secondary windings are mechanically and electrically connected to strip conductors each having an outer end outside the polygonal cylinder (formed by the legs and yokes).
  • EP 2 388 236 A1 discloses a three-phase power supply arrangement in which each of the three secondary windings has, for example, seven terminals (73-79). However, the structural / geometric arrangement of the power supply arrangement - in particular the terminals and their connection to the circuit - is not disclosed.
  • EP 2 479 880 A1 discloses a three-phase power supply arrangement in which each of the three transformer core legs has two secondary-side windings.
  • the structural / geometric arrangement of the terminals and their connection to their circuit - is not obvious.
  • Power supply arrangement with a transformer with a cylinder-like transformer core was now a skilled person for the development and design of power supply arrangements for polysilicon reactors with the task of developing a power supply arrangement described above so that it can be optimally used for the supply of polysilicon reactors.
  • the terminals of the secondary windings are outside the cylinder.
  • the known advantage of the compact, space-saving design of the transformer is combined by the invention with an optimized adaptation of the external design of the power supply arrangement to the external design of a polysilicon reactor.
  • material can be saved by the fact that the secondary circuit of the transformer can be placed directly on the outside of the transformer.
  • the paths between the terminals of the secondary windings can be shortened. If the loads, for example a polysilicon reactor, are arranged above the power supply arrangement, the paths between the secondary wiring of the transformer and the loads can also be shortened compared to the current state of the art.
  • the first carriers are led out of the transformer laterally. Thus, the terminals of the secondary windings are easily accessible from the outside.
  • the first carriers are preferably led out of the transformer at the locations where the secondary windings, to the terminals of which the carriers are connected, project beyond the cylinder described by the transformer core. Unlike known triangular transformers, the terminals of all secondary windings are not on a single side of the Transformers led out. Rather, the first carriers are found on all sides of the transformer.

  • the circuit carriers may be attached to the outer ends of the first carrier.
  • the first carriers can carry the circuit carriers in whole or in part. But it is also possible that the first carrier experienced no mechanical stress by the circuit carrier.
  • the transformer may have one or more holding means, on which or the transformer core is arranged, and the or also the circuit carriers bear wholly or partly directly or indirectly bear or.
  • the holding means may comprise a frame on which the transformer rests and which advantageously also holds and / or supports the circuit carriers.

  • one of the power controllers, several power controllers or all power controllers can be arranged on the circuit carriers.
  • the outputs of the power controllers whose inputs are connected to the outer conductor terminals of one of the secondary windings, can be electrically interconnected at one point.

  • Terminals of the primary windings of the first transformer are advantageously guided into an inner space of the first transformer, which is not filled by the transformer core and windings of the first transformer. This makes it easy to separate the secondary-side connections and the primary-side connections.
  • windings of another transformer are arranged on the transformer core of the first transformer.
  • the windings of the first transformer and of the further transformer can then be arranged in overlying or juxtaposed areas on the legs of the transformer core.
