Definitions

  • the invention relates to switches with extinguishing devices for the rapid extinction of an arc during the separation process.
  • Electrical switches are components in a circuit that establish an electrically conductive connection (switching state "ON” or ON state) or disconnect (switching state "OFF”, or OFF state) by means of internal electrically conductive contacts.
  • switching state "ON” or ON state or disconnect

  • an inductive circuit is disconnected by a switch, the flowing current can not go to zero immediately.
  • an arc forms between the contacts.
  • This arc is a gas discharge through a non-conductive medium such as air.
  • Arcs in AC-powered switches typically clear at zero crossing of the AC current.
  • Extinction of an arc is typically accelerated by the use of a magnetic field that is poled to exert a driving force on the arc toward the quenching chambers.
  • the size of the driving force depends on the strength of the magnet or magnets.
  • permanent magnets are used to generate a strong magnetic field.
  • the driving force of the magnetic field towards the quenching chambers is given only at a certain current flow direction.

  • the switch according to the present invention has a fast, reliable and current-independent quenching behavior and therefore prevents polarization-related installation errors and is suitable for applications where switches are required for both current directions.
  • the term "substantially” in the present invention includes all embodiments that deviate less than 10% from the setpoint or mean.
  • a switch according to the present invention comprises any type of switches suitable for multi-pole operation with switching chambers having at least two immovable contacts which can be electrically closed by at least one movable contact piece.
  • These switches can be, for example, two-pole or multi-pole switches.
  • the number of switching chambers may be two or more switching chambers, wherein the switching chambers are preferably operated parallel to each other.
  • switches in the context of the present invention may also be switches in which the two or more switching chambers are connected in series and which thus constitute, in principle, single-pole switches.
  • Such switches are nevertheless suitable for multi-pole operation, since only the interconnection of the switching chambers would have to be adapted for multi-pole operation. Examples of these switches are contactors, switch disconnectors or circuit breakers.
  • the switch is suitable for DC operation, but could also be used in AC operation.
  • the polarity-independent DC operation refers to the operation of the switch in a DC circuit, wherein it does not depend on the current direction in the switch for the rapid erasure of the arcs in the switch.

  • a switching chamber includes four extinguishing devices for reliably extinguishing both arcs in the respective extinguishing devices.
  • the advantage of the claimed arrangement is the simple, symmetrical and therefore cost-effective design of the switch. The stronger the magnetic field at the location of the arc, the faster the arc is driven into the extinguishing device and thus deleted.
  • Extinguishing devices may be any suitable means for extinguishing an arc, for example, cooling plates or extinguishing chambers.

  • first arc guide plates extend in two opposite directions respectively from at least one of the first contact regions and the corresponding second contact region to two extinguishing devices arranged at the end of the arc baffles, respectively, as first extinguishing chambers.

  • the arc is subdivided in the first quenching chamber into a plurality of partial arcs (Deionwait).

  • the second quenching chamber may have a similar or the same basic structure as the first quenching chamber and optionally include the parts that have already been described in the first quenching chamber.

  • the cooling plate extends to the second contact region of the movable contact piece.

This avoids that an arc must be driven to erase towards the bridge assembly, which avoids an increased thermal load on the bridge assembly and thus increases the life of the switch. Furthermore, this embodiment has only first extinguishing chambers, whereby the installation height per pole can be reduced. Due to the symmetrical design of the switching chambers, the running behavior of the arcs is made more favorable.
  • the first arc guide plates extend into the first extinguishing chambers for each of the two opposite directions.
