Definitions

  • the invention relates to a conductor arrangement.
  • a surge arrester is designed to limit electrical overvoltages, such as those that can occur during a lightning strike.
  • the surge arrester may be a long and heavy component that requires support. When a permanently installed electrical conductor is used, the electrical conductor can support the surge arrester.
  • EP 3 001 430 A1 It is known to form a discharge current path of a surge arrester with a firmly clamped connection and thus to stabilize it.
  • the European patent application EP 3 208 811 A1 shows a surge arrester arrangement in which a stationary contact piece of a disconnecting device is connected to a varistor.
  • Switchable surge arresters exist in which an electrical connection from the electrical conductor to the surge arrester can be severed. Disconnecting the electrical connection from the electrical conductor to the surge arrester can be relevant, for example, to perform a high-voltage test on the electrical conductor. However, if the electrical connection from the electrical conductor to the surge arrester is severed, the surge arrester cannot be supported by the electrical conductor. This can lead to a shortening of the service life of the surge arrester.
  • Such designs are known, for example, from European patent application EP 3 514 899 A1 and the Japanese release JP 2000-232708 A known.
  • the object of the invention is therefore to provide a conductor arrangement with a surge arrester in which a surge arrester has a long service life.
  • the conductor arrangement comprises a housing, a bushing insulator, an electrical conductor, a surge arrester having a longitudinal direction, an operating state in which the surge arrester is configured to limit an overvoltage occurring in the electrical conductor, and a test state in which the surge arrester is not configured to limit the overvoltage, and an electrically insulating support arranged in the longitudinal direction between the surge arrester and the electrical conductor, wherein the support is supported by the electrical conductor and the surge arrester is supported by the support, wherein the bushing insulator is configured to hold the electrical conductor and to insulate it from the housing, wherein the surge arrester has a conductor connection arranged at least partially displaceable relative to the remaining surge arrester and thus configured to switch the surge arrester between the operating state and the test state, wherein the conductor connection in the operating state is further away from the remaining surge arrester than in the test state protrudes.
  • the surge arrester is indirectly supported by the electrical conductor both in the operating state and in the test state
  • the surge arrester has a conductor connection which is arranged to be at least partially displaceable relative to the remaining surge arrester and is thus designed to switch the surge arrester between the operating state and the test state, wherein the conductor connection in the operating state is further away from the remaining Surge arrester than in the test state.
  • This allows the surge arrester to be brought into the operating state by moving the conductor connection toward the electrical conductor, and into the test state by moving the conductor connection away from the first conductor.
  • In the operating state there is an electrically conductive connection from the electrical conductor to the surge arrester, and in the test state, the electrically conductive connection is interrupted.
  • the conductor arrangement has a movable connection by means of which the surge arrester and the support are coupled to one another such that the support can be displaced in the longitudinal direction relative to the surge arrester.
  • a gap is provided in the longitudinal direction between the surge arrester and the support. This makes it possible to compensate for thermal expansion, for example of the conductor, the support, and/or the surge arrester, by narrowing the gap in the longitudinal direction. This makes it possible to avoid mechanical stresses in the conductor arrangement during thermal expansion, thereby extending the service life of the conductor arrangement.
  • a flexible ring is arranged in the recess between the support and the surge arrester, the rotational axis of which is essentially parallel to the longitudinal direction. This makes it possible to cushion transverse forces that have a component perpendicular to the longitudinal direction. The transverse forces can be relevant, for example, during transport of the conductor arrangement. By cushioning the transverse forces, the service life of the conductor arrangement is particularly long.
  • the surge arrester has a contact cap which is arranged at the longitudinal end of the surge arrester facing the electrical conductor and in which the movable connection and in particular the recess are arranged.
  • the contact cap can be electrically be conductive and, for example, comprise a metal. It is particularly preferred that the contact cap has a geometry that reduces the electric field strengths to the electrical conductor and leads to grounding. For this purpose, the contact cap can, for example, have rounded corners.
  • the conductor arrangement preferably comprises an electrically conductive component configured to electrically connect the support to the surge arrester, in particular to the contact cap.
  • the support may comprise an electrically conductive contact piece at its longitudinal end facing the surge arrester, which contacts the electrically conductive component. This prevents partial discharges at the contact piece, thereby extending the service life of the conductor arrangement.
  • the electrically conductive component is a contact spring, in particular a helical spring, or a bushing having inwardly projecting lamellae.
  • the conductor arrangement has a fixed connection by means of which the support is fixedly attached to the electrical conductor.
  • the surge arrester particularly preferably has a conductor connection which is arranged so as to be at least partially displaceable relative to the remaining surge arrester and is thus designed to switch the surge arrester between the operating state and the test state, wherein the conductor connection protrudes further from the remaining surge arrester in the operating state than in the test state, wherein the contact disk has a contact recess and the conductor connection has a contact pin which is arranged in the contact recess in the operating state and is arranged outside the contact recess in the test state.
  • the surge arrester preferably comprises one or more varistors.
  • the plurality of varistors can be connected in series and/or parallel.
  • the varistor(s) can be electrically conductively connected to the conductor connection in the operating state.
  • the varistor(s) can be metal oxide varistors (MOVs), for example.
  • the conductor arrangement preferably has a housing that encapsulates the electrical conductor, the surge arrester, and the support. Such a conductor arrangement is suitable wherever it is not possible to implement the electrical conductor as an overhead line, such as in a power plant or a transformer substation.
  • the electrical conductor is particularly preferably supported by the housing and/or by a wall that separates two chambers in the housing.

  • the conductor connection 7 can have a drive 7c configured to displace the contact pin 7a away from the electrical conductor 2 to bring the surge arrester 3 into the test state, and to displace the contact pin 7a toward the electrical conductor 2 to bring the surge arrester 3 into the operating state.
  • the conductor connection can have a drive rod 7d, a hand crank 7e, and a transmission configured to translate a rotation of the hand crank 7e into a longitudinal displacement of the drive rod 7d.
