Definitions

  • the invention relates to switches with extinguishing chambers for the rapid extinction of an arc during the turn-off.
  • 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
  • switching state "OFF" or OFF state
  • current-carrying connection to be cut
  • 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. Electric arcs in AC-powered switches clear at the zero crossing of the AC current at the latest.
  • 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. In order to avoid polungs employment of switches or switches are needed for both directions, would be switch with a fast and independent of the respective polar erase behavior for arcing, which arise during the switching off of the switch between the open contacts, desirable.
  • a switch suitable for a polarity-independent DC operation with at least two separate immovable contacts each having a first contact region and at least one movable electrically conductive bridge contact with two second contact regions for producing an electrically conductive connection between the first and second contact regions in the ON state the switch and for disconnecting the first and second contact regions in the OFF state of the switch, with at least one magnet suitable for generating a substantially constant magnetic field in the region of the first and second contact regions for applying a magnetic force to one between the first and second contact regions during the production of the OFF-state occurring arc, with two first extinguishing chambers for extinguishing the arcs with a first current direction, wherein jew jewelery from the first extinguishing chambers at least in the OFF state eils a first arc guide plate to the first contact region and a second arc guide plate extends to the second contact region for deriving the arc in the first extinguishing chambers, and wherein the movable bridge contact comprises
  • the bridge arrangement designates the arrangement with which the bridge contact is movably supported, for example by means of a spring and a guide in a correspondingly shaped bridge assembly made of plastic.
  • the bridge plates here represent a thermal protection for the bridge arrangement.
  • a switch according to the present invention comprises any type of single or multi-pole switches with at least two immovable contacts which can be electrically closed by at least one movable bridge contact. Examples of these switches are contactor, switch-disconnector or circuit-breaker.
  • 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.
  • arcs may occur between the first and second contact regions, in which the current can flow from the first to the second contact region or vice versa.
  • the magnets in the switch In a preferred arrangement of the magnets in the switch, the arc between one of the first and second contact areas in the corresponding first quenching chamber and the arc between the other first and second contact areas along the bridge plate driven. In an operation of the switch with a reverse current direction, the erase behavior would look the same, except that then the arcs would be driven respectively to the other extinguishing chamber or the other bridge plate.
  • the magnets are arranged in the switch so that the arcs between the two first and two second contact regions are driven by the magnetic field in each case in the first extinguishing chambers at a certain current direction in the switch or driven in reverse current direction in each case along the Brückeleitbleche. Both variants are included within the scope of the invention.
  • the term "substantially" in the present invention includes all embodiments that deviate less than 10% from the nominal value.
  • the first and second contact areas denote the areas of the fixed contacts and the movable bridge contact which are in direct contact after the closing of the switch (ON state).
  • ON state a current flows from one of the two first contacts via the first contact region into the second contact region in contact therewith, from the latter via the electrically conductive bridge contact to the other second contact region of the bridge contact and from there via the other first contact Contact area in the other immovable contact.
  • the first contacts and the first and second contact areas and the bridge contact consist of an electrically conductive material.
  • the first and second contact regions may be subareas of the stationary contacts or the bridge contact, or separate components which are arranged on the stationary contacts or the bridge contact.
  • the above movement is along a movement axis of the bridge contact perpendicular to the surfaces of the bridge Contact areas.
  • the bridge contact is for example in a bridge assembly, preferably made of plastic, movably supported by a spring, which also generates the required contact pressure.
  • the movement axis is aligned perpendicular to the direction of movement of the arc in the first extinguishing chambers.
  • the switch is opened by moving the bridge contact in the opposite direction.
  • the movement of the bridge contact can be done manually or electrically.
  • the first and second contact areas may differ in shape and material.
  • the areas of the first and second contact areas can vary between extended areas and punctiform contacts.
  • the material of the contact areas may be any suitable electrically conductive material, for example, silver-tin oxide.
  • the first quenching chamber comprises any type of components that are suitable for bringing an arc to extinguish.
  • these include a plurality of quenching plates between a first and a second arc guide plate, which are both arranged in the quenching chamber parallel to each other.
  • the magnets used preferably permanent magnets, are used to generate a strong homogeneous magnetic field and to apply a force on the arc towards the quenching chambers. For rapid extinguishment of an arc, the Lorenz force is preferably applied to this by the permanent magnets until it enters the quenching chamber.
  • the quenching plates in the quenching chambers are for example V-shaped.
  • the arc is divided in the quenching chamber into a plurality of partial arcs (Deionwait).
  • the required minimum voltage for maintaining the arc is proportional to the number of extinguishing plates present in the quenching chamber, whereby the voltage required to maintain the arc exceeds the available voltage, which leads to the extinction of the arc.
  • the quenching plates are held in an insulating material to which the arc guide plates are also attached.
  • the arc guide plates can have any shape that is suitable to direct the arc in the quenching chambers.
  • the Arc guide plates can also be designed as a stamped and bent part.
  • the thickness and width of the arc guide plates can also vary. The distance between the first (lower) and the second (upper) arc guide plate can grow with increasing distance to the first and second contacts.
  • the bridge plates each extend to the second contact points of the movable bridge contact. Since the arc arises when switching off between the first and second contact areas, it is expedient that the bridge plate comes close to the location of the arc in order to be able to effect a rapid deletion via a fast routing of the arc.
  • the distance between the bridge plate and the back of the stationary contact increases with increasing distance to the axis of movement of the bridge contact.
  • the arc gap is increased and thus increases the arc voltage necessary to maintain the arc. If the arc voltage exceeds the operating voltage of the switch, the arc goes out.
  • the magnet and the bridge plate are arranged such that the magnetic field also extends into the region between the bridge plate and the immovable contact.
  • the magnetic field drives the arc with the second current direction in the direction of the bridge plate and thus accelerates the extinguishing of the arc.
  • the magnet is arranged such that the field strength of the magnetic field is substantially equal between the first and second contact areas and between the bridge plates and the stationary contacts.
  • the greater the magnetic field strength at the location of the arc the stronger the driving Lorenz force acts on the arc.
  • a strong magnetic field in the range of movement of the arcs can act for both current directions.
  • the magnet is a permanent magnet.
  • a very strong permanent magnetic field may be provided by a permanent magnet which is, for example, a rare earth magnet.
  • rare earth magnets are made of NdFeB or SmCo alloy. These materials have a high coercive force and therefore also allow, for example, a provision of the magnets as very thin plates.
  • the permanent magnets are arranged so that they generate a substantially homogeneous magnetic field at least in the region of the first and second contacts, preferably along the arc guide plates and bridge plates. The time until the arc is driven into the quenching chambers or along the bridge plates depends on the magnetic field strength and the homogeneity of the magnetic field.
  • the permanent magnets are preferably arranged so that they generate a magnetic field perpendicular to the current flow in the arc and perpendicular to the desired direction of movement of the arc, ie along the arc guide and bridge plates.
  • the permanent magnet for this purpose comprises two plate-shaped permanent magnets whose surfaces are arranged parallel to each other and extend at least over the first and second contact areas parallel to the bridge contact and the first and second arc guide plates and the first Brückleitblechen at least in the OFF state of the switch.
  • the permanent magnets are thus also substantially parallel to the direction of movement of the movable bridge contact.
  • the permanent magnets are thin plates, since the available space in the switch is limited.
  • the distance between the opposed permanent magnets to produce a homogeneous magnetic field may vary as a function of the magnetic material used.
  • the first and second contact areas and at least parts of the movable bridge contact and the immovable contacts and at least parts of the arc guide plates and bridge plates are arranged.
  • the magnetic inference can take place via a magnetic material bridge between the opposing permanent magnets.
  • the distance between the permanent magnets for a given thickness and material of the permanent magnet in a Switches for operation with 1500 V DC and currents of 30A are about 8mm.
  • the magnet for exerting a Lorenzkraft on the arc by a total of 4 permanent magnets arranged as two pairs of, for example, flat plates in the region of the two respective first and second contact surfaces executed.
  • the two pairs of permanent magnets each have a field with opposite Create field direction. If the field direction in both pairs of permanent magnets were the same in another embodiment of the switch, the arcs would either be driven into the first quench chambers or toward the bridge to the bridge plates and the second quench chamber, respectively.
  • the geometric shape of the magnets may be chosen differently in other embodiments in the context of the present invention.
  • first arc guide plates are each firmly connected to the first contact regions.
  • obstacles to the movement of the arc such as air gaps are avoided, at least for the immovable contacts.
  • the bridge plates extend into at least one second quench chamber, which is arranged on the movable bridge contact.
  • the bridge plate acts as an arc guide plate.
  • the term "arranged on the movable bridge contact" here also means the possibility that the bridge contact and the quenching chamber are indirectly mechanically interconnected via the bridge arrangement.
  • the second quenching chamber may have a similar or the same basic structure as the first quenching chamber.
  • the size of the second quenching chamber may be smaller than the first quenching chamber due to the position of the second quenching chamber at the movable bridge contact.
  • the bridge contact comprises two separate second extinguishing chambers into which the bridge plates each extend.
  • the immovable contacts each comprise a contact baffle extending from the first contact region to the second quenching chamber.
  • the arc is conducted in accordance with the first extinguishing chambers from the first contact regions along an arc guide plate, here the contact guide plate of the first contact, to the second extinguishing chamber.
  • This contact baffle of the first contact results in the same Lorenzkraft to faster transport of the arc in the second chamber. Due to the presence of the second quenching chamber, the first quenching chamber can also be more compact, i. smaller, to be built.
  • the second quenching chamber includes extinguishing plates for extinguishing the arc, which are arranged parallel to the axis of movement of the bridge contact. As a result, a small design of the second quenching chamber is made possible.
  • the magnet extends to the second quenching chamber.
  • the driving magnetic force acts on the arc until it arrives in the quenching chamber, which additionally supports a fast and safe arc quenching.
  • the switch according to the invention enables the rapid extinguishing of arcs in first and second arcuate plates or bridge plates, since the magnetic fields, the arcs, especially in strong permanent magnets, regardless of the current direction in the switch in one or the other Drive the extinguishing chamber or the bridge plate.
  • the bridge plates provide thermal protection for the bridge assembly.
  • each of the first arc guide plate and the contact baffle of the first contact are directly connected to the first contact area, so that when moving the arc to the first or second extinguishing chamber to no obstructing barriers such Air gaps are to be bridged.
  • the arrangement of the permanent magnets as parallel surfaces in close proximity to the first and second contact areas increases the driving Lorenz force on the arcs to the quenching chambers.
  • the deletion of Arcs thus happens in a predetermined safe, fast and independent of the direction of current in the switch way.

  • the bridge contact 3 is moved in the opposite direction along the movement axis BA, so that between the first and second contact regions 21, 22, 31, 32 a Separation path arises. In these separation sections arcs 51, 52 may arise after switching off.
  • the switch 1 comprises at least one magnet 71, 72, which generates a substantially constant magnetic field M in the region of the first and second contact regions 21, 22, 31, 32 for exerting a magnetic force F1, F2 an arc 51, 52 located between the first and second contact regions 21, 22, 31, 32 is provided.
