Definitions

  • the invention relates to an electrical contact arrangement having a first phase conductor run and a second phase conductor run, which are connected to one another in an electrically conductive manner via a coupling point.
  • Such an electrical contact arrangement is for example from the international publication WO 2011/113479 A1 known.
  • the contact arrangement there connects a first phase conductor run with a second phase conductor run via a coupling point in an electrically conductive manner.
  • the coupling point has two pairs of sockets and bolts which are each slidably inserted into one another, the sockets in turn being in electrical contact with one another via current bands.
  • thermally induced changes in length can be compensated.
  • the known arrangement has the disadvantage that a large number of contacting points are provided, which increase contact resistances and thus increase the problem of thermal stress.
  • an electrical contact arrangement with limited current carrying capacity is created.
  • the pamphlet DE 15 40 147 A1 shows an electrical contact arrangement having a first phase conductor run and a second phase conductor run, which are connected to one another in an electrically conductive manner via a coupling point, the first phase conductor run having a plurality of subconductors.

  • this object is achieved in an electrical contact arrangement of the type mentioned at the outset in that the first phase conductor run has several subconductors and the second phase conductor run has several subconductors which are alternately connected to a contact plate.
  • An electrical contact arrangement is used to form an electrically conductive connection between a first phase conductor run and a second phase conductor run.
  • Such contact arrangements can be used, for example, in transformer construction, for example to electrically connect electrical windings to outlets of a transformer or to lengthen lines.

  • the barrier 16 is formed from an electrically insulating material, for example pressboard.
  • the barrier 16 is used for electrical insulation of the electrical contact arrangement surrounded by the barrier 16.
  • the barrier 16 for its part is exposed to an electrically insulating fluid and also serves to conduct or influence the flow of an electrically insulating fluid which flows around and through the electrical contact arrangement.
  • the spacer device 13 is shown together with the contact plate 12 attached to it.
  • the enlargement is intended to describe the manner in which the stud bolts 13b and adapter plate 13a are fastened.
  • the stud bolts 13b are fixed to the adapter plate 13a by means of screw connections.
  • the screw connections are arranged in through bores of the adapter plate 13a, with screw heads being countersunk in order to screw the adapter plate 13a with its side facing away from the contact plate 12 flush with the mouth opening flange 8 of the first guide channel 4.
  • the outer diameter of adapter plate 13a and contact plate 12 have approximately the same dimension. However, the ring width of the contact plate 12 is greater than the ring width of the adapter plate 13a.
  • the subconductors protrude through the ring opening surrounded by the adapter plate 13a 1a, 1b, 1c of the first phase conductor run 1 in the direction of the contact plate 12. There, the wire end fittings 14 of the subconductors 1a, 1b, 1c of the first phase conductor run 1 are distributed on a circular path.
  • the circular path on which the subconductors 1a, 1b, 1c of the first phase conductor run 1 are distributed has a smaller diameter than the circular path on which the wire end fittings 14 of the subconductors 2a, 2b, 2c of the second phase conductor run 2 are distributed.
  • the subconductors 1a, 1b, 1c, 2a, 2b, 2c of the first and second phase conductor line 1, 2 are each arranged exclusively on one side of the contact plate 12 and aligned in the same direction so that the threaded bolts of the wire end fittings 14 protrude through the contact plate 12 in opposite directions and can be braced against the contact plate 12 in opposite directions.
  • the position of the contact points of the wire end fittings 14 of the subconductors 1a, 1b, 1c, 2a, 2b, 2c is selected such that subconductors 1a, 2a, 1b, 2b, 1c, 2c of the first and second phase conductor tracks 1, 2, respectively, assigned to one another lie on a radius.
