Definitions

  • the invention relates to the field of switch technology, in particular the high and medium voltage switch technology. It relates to a contact arrangement for a vacuum interrupter chamber according to the preamble of claim 1 and to a vacuum interrupter chamber and a switching device.
  • Such a contact arrangement and such a vacuum switching chamber are for example from the published patent application DE 197 05 1 58 as well as from the patent US 4,847,456 known.
  • the outer contact pieces are electrically connected in parallel and spatially arranged closely adjacent to the inner contact pieces.
  • One of the inner contacts is movably supported while the others Contact pieces are stationary.
  • the outer contact pieces are designed as AMF contact pieces.
  • a further increase in the switching capacity at comparable switch size is desirable.
  • a high short-circuit breaking capacity is desirable.
  • Out DE 1 196 751 is a contact arrangement for a vacuum switch disclosed with a pair of slotted cup-shaped contact pieces, wherein the pot bottom of the inner pot-shaped contact piece is formed as a part of the pot bottom of the outer pot-shaped contact piece.
  • the inner and outer contact pieces are (at their upper pot edges) spatially widely spaced from each other.
  • a contact arrangement for a vacuum interrupter chamber in which slotted pipe sections are provided as inner contact pieces and outer contact pieces.
  • the inner tubular contact piece is slotted so that thereby resilient contact tongues are formed. This is intended to create a plurality of separate mechanical contact points with a defined spring constant become.
  • an additional contact piece is arranged within the inner resilient contact piece, which is provided for carrying operating currents and through which low contact resistance can be realized. When opening the switch, the additional contact piece is first lifted. As a result of the associated increase in resistance at the additional contact piece, the current then flows through the inner resilient contact piece. After lifting the inner resilient contact piece then forms an arc.
  • GB 1 145 451 is a contact arrangement for a vacuum interrupter disclosed with three pairs of nested slotted cup-shaped contact pieces.
  • the pairs of contact pieces should be designed so that when a contact separation of the two contact pieces of each of the three pairs of contact pieces ever an arc is ignited and then rotate these three arcs between the two contact pieces of each pair of contact pieces and respectively form a substantially cylindrical arc curtain.
  • Out DE 30 09 925 is a contact arrangement for a vacuum interrupter chamber known with two cup-shaped slotted contact pieces arranged one inside the other. Between the pot walls of the cup-shaped contact pieces a non-slotted ring is arranged. As a result, a greater mechanical strength of the contacts is achieved.
  • the electrical conductivity of the ring material (stainless steel) is significantly lower than that of the contact piece material (copper). The arc rotation is therefore not weakened by the non-slotted ring.
  • An object of the invention to provide a contact arrangement and a vacuum interrupter chamber of the type mentioned, which allow an increased switching capacity.
  • a high short-circuit breaking capacity should be achieved at a high arc voltage.
  • the contact arrangement should have a low resistance and can carry large currents.
  • An inventive contact arrangement for a vacuum interrupter chamber has a pair of inner contacts formed as RMF contacts and a pair of outer contacts.
  • the outer contact pieces are electrically connected in parallel to the inner contact pieces and spatially arranged closely adjacent to the inner contact pieces. At least one of the inner contact pieces is movably mounted.
  • the outer contact pieces are designed as RMF contact pieces.
  • the inner contact pieces are formed substantially disc-shaped.
  • the inner and the outer contact pieces are arranged and formed such that a resulting in a Ausschaltvorgang between the inner contact pieces arc can commute completely or partially between the outer contact pieces.
  • An RMF contact has the significant advantage over an AMF contact that the current path resistance of the vacuum interrupter chamber at a high contact pressure (up to several thousand Newtons) is at a lower level.
  • the axial magnetic field of the AMF contact is generated by the flowing current, there is a large inductance;
  • the axial magnetic field of the AMF contact is generated by permanent magnets, there are large eddy current losses.
  • RMF contacts over AMF contacts is its higher arc voltage.
  • the arc voltage at RMF contacts can be more than 100 V and up to 1 50 V, while the arc voltage at AMF contacts is typically only 30 V to 50 V and in any case is significantly less than 100 V.
  • the arc which arises during a turn-off operation can commute completely or partially to the outer contact piece pair. Whether one or two arcs burn depends on the current.
  • a concentrated separation arc After disconnecting the initially contacting contacts under load, a concentrated separation arc first occurs.
  • a contracted arc column forms between the contact pieces during the RMF contact. If the contact spacing is further increased in the course of the switch-off process, a partial commutation or, if the design is designed accordingly, a full commutation occurs.
  • the switching chamber according to the invention can carry at least the same current and switch as a switching chamber with only one RMF contact piece pair. If the outer contact pieces are not formed as rated current contact pieces, so do not touch when the switch is closed, there is an improved switching performance, since the arc then after the Commutation on the outer contact pieces on a mechanically and thermally unstressed surface of low roughness rotated.
  • the inner contact pieces are disc-shaped, a small resistance of the contact arrangement can be achieved, and large currents can be worn.

In the latter case, the movement of the movable outer contact piece is advantageously coupled to the movement of the movable inner contact piece, advantageously by a rigid connection of the two movable contact pieces.
  • a nominal current contacts are advantageously the inner contact pieces.
  • the movable inner contact piece projects beyond the movable outer contact piece in the axial direction. It can also serve both the inner and the outer contacts as rated current contacts. With great advantage, the contact arrangement is designed as a firmly soldered contact system.
