Definitions

  • the invention relates to a kit for a bushing arrangement for the electrical connection of a transformer system through an opening in a housing wall of the transformer system.
  • a implementation arrangement for transformers is, for example, from EP 1 614 127 B1 out.
  • Known bushing arrangements usually have an electrical conductor which is guided from the outer area of the transformer to the inner area of the transformer by means of insulating elements arranged within the opening of a housing wall of the transformer system.
  • the housing of the transformer system has earth potential, the conductor, on the other hand, can be subjected to a voltage of up to or more than 1kV and must therefore be adequately insulated from the housing wall by the arrangement of the insulating elements.
  • kit of the type mentioned at the outset which, according to the invention, comprises an elongate electrical conductor and at least one first insulating element that can be inserted into the opening in the housing wall, with at least one first section as well as a second section lying on the outside in relation to the housing wall in the assembled state, and wherein the at least one first insulating element has an opening for at least partially accommodating the conductor, the opening of the insulating element for guiding the conductor from an outside of the housing wall towards an inside of the housing wall, wherein the first section of the electrical conductor has a widening which forms a stop surface for limiting a longitudinal displacement of the conductor through the opening in the first insulating element in the direction of the outside of the housing wall, the second section of the electrical conductor having a threaded section for receiving a Screw nut for clamping the conductor against an outside of the housing wall, wherein the at least one
  • the kit according to the invention creates a bushing arrangement that can already be preassembled and, in the preassembled state, can be inserted from the outside into the opening in the housing wall of the transformer system and assembled from the outside.
  • the at least one clamping element is brought into the second position, approaching the periphery of the at least one first insulating element, with the at least one clamping element being brought back into the first position as soon as it has passed the opening in the housing wall is, and thus secured against pulling out the bushing arrangement.
  • the at least one clamping element can, for example, assume the first position independently by spring force or the effect of gravity, or can also be brought into the first position by other mechanisms such as tightening a screw nut arranged on the threaded section of the electrical conductor.
  • tightening a screw nut arranged on the threaded section of the electrical conductor the conductor is braced against the outside of the housing wall (whereby further elements can typically be arranged between the screw nut and the housing wall, such as a cap, sealing rings, etc. mentioned below), by the conductor, due to its broadening in the first section, presses against the at least one insulating element and is restricted in its movement out of the interior of the transformer installation.
  • the expression "circumference of the at least one first insulating element" is to be understood as meaning that it is formed without the at least one first clamping element - the shape of the clamping elements themselves is therefore not included in the scope of the insulating element.
  • the bushing arrangement is fixed in its position by tightening the screw nut, which can also form part of the kit.
  • the at least one clamping element prevents the bushing arrangement from slipping out. This makes it possible to quickly assemble the bushing arrangement from the outside, without requiring access for assembly tools to the interior of the transformer system.
  • the voltage that is introduced into the transformer through the bushing arrangement and is discharged from it is, for example, 1 to 3 kV.
  • the currents that can be supplied or discharged through the bushing arrangement are, for example, 1250 A.
  • a bushing arrangement can be assigned to each phase.
  • the openings in the housing wall of a transformer system are typically adapted for specific bushing arrangements and vice versa.
  • the bushing arrangement can therefore be appropriately dimensioned for the respective application or housing opening.
  • the at least one clamping element is arranged resiliently on the at least one first insulating element, the spring force being selected such that the clamping element is pressed by the spring force from the second position into the first position.
  • the at least one clamping element can preferably be arranged in such a way that it can change into the second position through the action of a force component which acts in the direction of the opening of the at least one insulating element. If the bushing arrangement is inserted into an opening in a housing wall of a transformer system, the clamping element can switch to the second position upon contact with the wall delimiting the opening, thereby blocking the insertion of the Feedthrough arrangement can be prevented in the housing opening. If the at least one clamping element is resiliently pressed into the first position, the at least one clamping element can be brought into the second position against the spring force, which leaves the clamping element after passing through the housing opening back to the first position.
  • the at least one first insulating element has a substantially cylindrical shape, with the at least one clamping element being accommodated completely within the peripheral surface (which in this embodiment corresponds to a lateral surface of a cylinder) of the at least one first insulating element, wherein the electrical conductor is rod-shaped and the opening of the at least one first insulating element is designed to receive a section of the electrical conductor that extends through the first insulating element in a form-fitting manner.
  • the at least one clamping element can be accommodated completely within the shape of the at least one first insulating element, as a result of which the circumference of the at least one first insulating element can be dimensioned in a particularly form-fitting manner in relation to the housing opening.

  • the clamping surfaces of the individual clamping elements thus form a common plane, as a result of which a particularly stable and uniform clamping effect is achieved, which also clearly defines the orientation of the bushing in relation to the housing wall.
  • the at least one clamping element is designed in the form of a small plate, with the at least one first insulating element having a depression along its circumference for receiving the respective clamping element, with the at least one clamping element in the assembled state being at least partially in the direction of the at least one

  • the at least one clamping element In order to precisely determine the position of the at least one clamping element in relation to the at least one first insulating element, provision can be made for the at least one clamping element to have an adjusting projection protruding at least partially in the direction of the at least one first insulating element in the assembled state in order to determine the position of the at least one clamping element in Having reference to the at least one first insulating element, wherein the at least one first insulating element has a corresponding depression for receiving the adjusting projection.
