Definitions

  • the invention relates to a switching device suitable for a DC operation, which comprises at least one pair of contacts with a first contact and a second contact, wherein at least one of the two contacts is movable and the two contacts in an on state of the switching device in contact with each other and in an off state of the switching device are out of contact with each other.
  • the switching device comprises an arc runner arrangement, which generates a magnetic field at least in the region of the contact pair, and a first arc guide arrangement, by means of which an arc occurring between the contacts is conducted with a first current direction to a quenching device for extinguishing the arc.
  • Such a switching device is from the EP 2 061 053 A2 known.
  • To provide a switching device for DC applications there is proposed to use the housing of a switching device for AC applications, wherein additionally at least one magnet is provided which has a magnetic field with substantially transverse to the separation paths of the current paths of the AC switching device field lines.
  • the housing In the housing, three receiving areas are provided for each one flow path, wherein each current path is associated with a movable switching contact element and two opposing fixed switching contact elements.
  • the three movable switching contact elements are jointly movable between a closed position, which corresponds to the switched-on state of the switching device, and an open position, which corresponds to a switched-off state of the switching device.
  • each current path is each associated with two arc quenching devices, which are each in the form of individual stacked, electrically insulated from each other quenching plates are formed.
  • each current path has two separating sections which, when the movable switching contact elements are open, extend between the ends thereof forming these ends associated first and second fixed switching contact elements. When the switching contact elements are opened, an arc forms along the separating sections, which arc can be extinguished with the aid of the arc-extinguishing devices.
  • DC applications since erasure of an arc can not be achieved due to current zero crossing, as in AC applications, DC applications require the provision of a magnetic field which drives the arc into one of the arc extinguishing devices.
  • This magnetic field is formed by permanent magnets, wherein a magnetic field is built up with field lines in an orientation which extend transversely to the separation lines and generate a Lorenz force on these arcs forming parting lines, which drives the arcs in the direction of one of the arc extinguishing devices.
  • an arc is driven between a first contact pair in the direction of a first arc quenching device and the arc between a second contact pair in a second arc quenching device. Since the movement of the arcs depends on the current direction, the switching device is suitable only for one direction of current, ie polarity.
  • the switching device were also operated in a reverse current direction, the arcs would not be driven into the arc extinguishing devices, but in the opposite direction to a switching bridge. Even if one reversed the magnetic polarity of one of the arc extinguishing devices, one of the arcs would always run in the direction of the switching bridge, which would result in a reduced service life, since the switching bridge or other components would be permanently damaged or even destroyed.
  • the EP 0 789 372 B1 also shows a switching device of the type mentioned.
  • a fixed contact is in this case provided with a fixed sheet traveler, which is designed circular arc.
  • a movable sheet traveler is provided, which can form an arc between the two bow travelers, which is moved via the arc runner assembly depending on the direction of current in different directions.
  • the latter is either centered in a first direction of rotation or in a second direction of rotation opposite to the first direction of rotation deflected, wherein the center corresponds to the center of the fixed bow traveler.
  • An arc having a first current direction is directed into a first arcuate channel and an arc having a second current direction opposite to the first current direction is directed into a second arcuate channel.
  • the two Bogenorganize extend around the center around and are separated by an insulating wall, juxtaposed.
  • the bow traveler channels are each part of an extinguishing device for extinguishing the arc.
  • the extinguishing devices further comprise quenching plates, which are arranged radially with respect to the stationary sheet traveler. The quenching plates are arranged such that they cover both Bogenorganizrkanäle and thus are part of both extinguishing devices.
  • Object of the present invention is to provide a switching device that can be operated independently of polarity and is as simple as possible.
  • a switching device suitable for a DC operation which comprises at least one pair of contacts with a first contact and a second contact, wherein at least one of the two contacts is movable and the two contacts in an on state of the switching device in contact and in a turned off state of the switching device are out of contact with each other.
  • the switching device comprises an arc runner arrangement, which generates a magnetic field at least in the region of the contact pair, and a first arc guide arrangement, by means of which an arc occurring between the contacts is conducted with a first current direction to a quenching device for extinguishing the arc.
  • a second arc guiding arrangement is provided, by means of which an arc occurring between the contacts is conducted to the extinguishing device for extinguishing the arc with a second current direction opposite the first current direction.
  • a permanent magnetic field is generated by means of permanent magnets in order to provide a magnetic field in a simple manner and current-independent.
  • the first arc guide arrangement is designed such that an arc is deflected with a first current direction in a first direction of rotation and directed to the extinguishing device.
  • the second arc guide arrangement is arranged such that an arc is deflected with a second current direction in a direction of rotation opposite to the first direction of rotation and directed to the extinguishing device. This means that the arc is deflected regardless of its current direction and is driven into the extinguishing device.
  • the paths which the arc must cover until it reaches the quenching device are preferably the same size in order to ensure the same switching behavior of the switching device in both current directions.
  • the first contact is a stationary fixed contact and the second contact is a movable contact.
  • the arc is deflected by the second contact on a side facing away from the first contact side of the second contact.
  • the arc is thus deflected to the rear of the movable contact, wherein the erasing device is arranged on the back of the movable contact.
  • the arc is driven in a direction in the quenching device, which is approximately parallel to the direction of movement of the movable contact.
  • the movable contact moves when opening the contact pair in the direction of the extinguishing device, so that the arc can be passed over the shortest path in the extinguishing device.
  • the quenching device is preferably formed as a deion quenching chamber with a plurality of mutually electrically isolated, mutually parallel quenching plates.
  • the quenching plates are preferably aligned parallel to the direction of movement of the at least one movable contact.
  • the arc guide assemblies each have a first baffle and a second baffle, wherein the two first baffles extend from the first contact in opposite directions and in the direction of the extinguishing device.
  • the first two baffles can accommodate the extinguishing device between them.

  • the two second baffles are preferably arranged on a contact carrier, which carries the second contact, wherein they can extend in opposite directions.
  • the second baffles are angled at their free ends in the direction of the extinguishing device.
  • the baffles therefore remain substantially plate-shaped, which simplifies the production of baffles.
  • a second variant is characterized in that the second baffles are bent annularly at their free ends.
