Definitions

  • the invention relates to a contact arrangement for an electrical circuit breaker, especially one High-voltage circuit breaker with a first contact piece and with a tubular coaxial opposite this Tulip contact piece, which has radially resilient contact fingers, which facing away from the first contact piece Ends are connected with a piece of pipe.
  • a contact arrangement for a high voltage circuit breaker with a tulip contact piece and a pin-shaped one Counter contact piece is already known from DE-OS 28 53 201. There is the tulip contact piece on the inside lined with an insulating layer.
  • circuit breakers are, for example, as high-voltage circuit breakers known in the form of isolating nozzle switches, where a pin-shaped contact piece a tulip-shaped Contact piece faces.
  • a switch drive separated from the pin-shaped contact piece.
  • the resilient contact fingers of the tulip contact piece on the pin-shaped counter contact piece When switched on store the resilient contact fingers of the tulip contact piece on the pin-shaped counter contact piece. in the The normal case is when such a switch is turned off between the tulip contact piece and the first contact piece, the pin contact piece, an arc drawn, one of which Base on the inside of the tubular tulip contact piece can stand.
  • the first contact piece for example ends facing the pin-shaped contact piece the resilient contact finger of the tulip contact piece from one erosion-resistant and therefore arc-proof composite material, e.g. WCu, manufactured so that the arc is as damage-free as possible withstand.
  • one erosion-resistant and therefore arc-proof composite material e.g. WCu
  • the present invention is therefore based on the object to create a contact arrangement of the type mentioned at the outset, which has a tulip contact piece that is more resistant to arcing, that is still necessary for an effective contact pressure Spring action of the contact fingers guaranteed.
  • the object is achieved by an arc-proof tubular, electrically conductive, inside of the tulip contact arranged insert, which is relative to the Pipe piece is arranged stationary, and the inside of the Contact fingers in the radially resilient area at least partially covered.
  • the insert covers the contact fingers can the arc with its base only on the inside put on the insert and thus damages the contact fingers Not. Because the insert itself is made of a burn-resistant Material is present, the insert will not be damaged through the arc in limits. The mission itself does not have to be elastic. The contact fingers can itself when the first contact piece moves into the tulip contact piece lift radially resiliently from the insert.
  • the outer diameter of the insert about the inner diameter of the tulip contact piece corresponds.
  • An advantageous embodiment of the invention provides that the use of a tungsten-copper alloy or There is graphite.
  • These materials are particularly arc-proof and sufficient conductive.
  • the invention can also be advantageously configured in this way be that the contact fingers essentially made of copper-chrome-zircon consist.
  • this alloy is resilient and highly conductive and, on the other hand, can be easily and safely mechanically Connect the ends of the contact fingers, which are made of a tungsten-copper composite consist.
  • the first contact piece facing ends of the contact fingers made of tungsten copper consist.
  • This alloy is very resistant to arcing.
  • An advantageous embodiment of the invention continues before inserting into a tubular contact piece carrier is pressed and in turn carries the pipe section.
  • the figure shows schematically a contact arrangement of a High voltage circuit breaker, with only the arcing contacts are shown.
  • a fixed, first pin-shaped contact piece 1 coaxially faces a tulip contact piece 2, the by means of a switch drive, not shown, in the axial direction is drivable to perform a switching movement.
  • the tulip contact piece 2 is carried by an insert 3, which in turn is pressed into a contact piece carrier 4 or is screwed in.
  • the insert 3 consists of a tungsten-copper structure, however, it could also be made of graphite or a other erosion-resistant material.
  • the insert is tubular and has an outer flange 5, which has a stop for the tulip contact piece 2 forms.
  • the tulip contact piece 2 is essentially tubular constructed and has a pipe section at one end 6, which has no slots, while the rest of the part of the tulip contact piece by radially arranged on the circumference running slots is divided into individual contact fingers 7.
  • the contact fingers are made of an elastic copper chrome zircon alloy, from which the pipe section 6 can also consist. This alloy is so elastic that the contact fingers are radially deflectable, especially when the first The contact piece moves into the tulip contact piece 2. In the The contact fingers are in the radially outward deflected position 7 'shown in dashed lines.
  • the first contact piece 1, the counter contact piece for the tulip contact piece 2 forms, facing ends of the contact fingers 7, 7 'exist made of a different material than the radially resilient part of the Contact finger 7, namely made of a burn-resistant tungsten-copper material. Such a material is largely arc resistant, but not very elastic, so that it is not to manufacture the resilient area of the contact fingers is suitable.
  • the tulip contact piece To produce the tulip contact piece, two tubular ones are used Parts fastened axially one behind the other, whereby the first piece is made of a CuCrZr alloy, while the second piece, which later faces the first contact piece 1 is made of a tungsten copper material. After this these two parts have been joined together, for example by means of copper welding, the Slots introduced between the contact fingers 7, 7 ', so that the finished tulip contact piece 2 is created.
  • a high current to be interrupted during shutdown generates an arc when the contact pieces are separated 8, between the first contact piece 1 and the ends of the tulip contact piece 2, which are made of tungsten copper.
  • This Arcing occurs in the course of the switching movement through outflow of an extinguishing gas taken into the interior of the tulip contact, and the arc base moves on the insert 3, where it will stand without causing any damage as long can until it is deleted.
  • the insert 3 can in the direction of the first contact piece 1 to to the ends of the contact fingers made of tungsten copper 7 are enough.
