Definitions

  • the present invention relates to a double-breaking circuit breaker for monitoring a circuit, comprising a coil for actuating a trigger, comprising a first switching contact pair, a first fixed switching contact and a first movable switching contact, a second switching contact pair comprising a second fixed switching contact and a second movable switching contact, wherein the movable switching contacts are actuated by the trigger, a first quenching chamber having a first guide rail and a first contact horn, which is electrically connected to the first fixed switching contact, a second quenching chamber with a second guide rail and a second contact horn, with the second fixed Switching contact is electrically connected.
  • Such double-breaking protective switching devices work in particular as switching and safety elements in electrical energy supply networks.
  • Circuit breakers are specially designed for high currents.
  • a circuit breaker is an overcurrent protection device in the electrical installation and is used in particular in the field of low-voltage networks.
  • Circuit breakers and miniature circuit breakers guarantee a safe shutdown in the event of a short circuit and protect consumers and systems from overload. For example, they protect cables from damage caused by overheating as a result of excessive current. This means that protective switching devices, such as circuit breakers and circuit breakers, can switch off the circuit automatically in the event of overload.
  • Double-breaking protective switching devices have two switching contact pairs, each consisting of a fixed Switching contact and a movable switching contact.
  • the movable switch contacts contact the fixed switch contacts.
  • the moving switch contacts remove from the fixed switch contacts.
  • the interruption of the current flow leads at least briefly to each protective switching device to a voltage flashover between the fixed switching contacts and the movable switching contacts, since the distance during the separation process of the switching contacts for isolation is not sufficient. If there is gas between the switching contacts, it is ionized by the flashover with a correspondingly high voltage difference between the switching contacts, and arcs are formed due to the gas discharge.
  • Such double-breaker protective switching devices such as circuit breakers or circuit breakers, are designed so that the resulting arcs when opening the switch contacts deleted and thus the flow of current is interrupted.
  • Such protective switching devices preferably have a coil, via which the current or part of the current flowing to the switching contacts, is passed. With a rapid increase in current, the coil attracts an armature that releases a trigger, in particular a latch. This release, which is pneumatically or hydraulically pressurized or resiliently biased, triggers the protection device and interrupts the flow of current.
  • a preloaded spring after the release of the trigger, in particular the pawl, move it and thereby separate the movable switch contacts from the fixed switch contacts.
  • Such protective switching devices furthermore have special arc extinguishing devices for faster extinguishment of the arcs.
  • the arc extinguishing devices are used to better interrupt or delete the arcs, which arise when opening the current-carrying switching contact pairs of the protective device.
  • the switch contacts When the switch contacts are disconnected, the current flows through increasingly small areas of an associated contact zone and heats them up more and more. Shortly before the actual separation of the switching contacts, a molten bridge is formed, which finally breaks off at low currents or evaporates at high currents. The current can therefore continue to flow only via an arc in the form of a conductive plasma column.
  • the strength of the arcs is influenced by the magnitude and type of the switched current.
  • short-circuit currents of more than 25,000 A may occur.
  • the arcs generate in the circuit breaker housing during its burning time in response to a supply of direct or alternating current temperatures of up to 20,000 K.
  • the high thermal load leads to adverse effects for the protection device.
  • metal and insulating parts can be damaged or destroyed by the arc effects. Consequently, it is necessary to extinguish the arcs as quickly as possible in order to minimize the thermal energy conversion.
  • modern protection switching devices arc extinguishing devices, the extinguishing chambers, guide rails, possibly blowing loops and / or metal sheets that cover an antechamber area, have.
  • Double-breaker protection devices that is to say protection devices with two switching contact pairs, have the advantage over simple circuit breakers, that is to say protection switching devices with only one switching contact pair, that two arcs are generated at the same time and thus a higher arc voltage can be built up. As a result, the arcs can extinguish faster and the converted energy in the contact zones or in the protective switching devices are kept low.
  • double-breaking protective switching devices that is to say, protective switching devices with two switching contact pairs.
  • a protective switching device with a double break is for example from the EP1548772 A1 known.
  • the two extinguishing chambers of the local protection switching device are arranged side by side and limit together one side of the antechamber (s) of the arc quenching device.
  • the contact horns of each quenching chamber project in the same direction and parallel to each other in the antechamber of the arc quenching device.
  • the disadvantage of this protective switching device is the arrangement of the extinguishing chambers or the contact horns to each other that the two magnetic fields of the moving arcs interfere with each other and hinder the flow of the other arc.
  • the flow of current in the arc quenching device runs EP1548772 A1 from the first fixed contact via the first resulting arc to the first movable contact and a second resulting arc on to the second fixed contact.
  • the resulting magnetic fields are directed opposite and do not support the respective neighboring arc, but hinder even its movement.
  • the object of the present invention is a double-breaking protective switching device for monitoring an electric circuit to create, which allows a particularly fast and safe deletion of the arcing when opening the switch contacts of the protective device.
  • a double-breaker protection device is to be created, which allows the resulting arcs in the antechamber region of the extinguishing chambers of the protective switching device does not damage the protective switching device.
  • a double-breaking protective switching device for monitoring a circuit, comprising a coil for actuating a trigger, a first switching contact pair, comprising a first fixed switching contact and a first movable switching contact, a second switching contact pair, comprising a second fixed switching contact and a second movable switching contact, wherein the movable switch contacts are actuated by the trigger, a first quenching chamber having a first guide rail and a first contact horn, which is electrically conductively connected to the first fixed switching contact, a second quenching chamber with a second guide rail and a second contact horn, with the second fixed switching contact is electrically connected, in which the first switching contact pair is rotated by 170 ° to 190 ° to the second switching contact pair next to the second switching contact pair and in which between the first movable switching contact and the second movable switching contact, a flexible electrical conductor is provided, which electrically conductively connects the first movable switching contact with the second movable switching
  • Such a double-breaking protection device allows that resulting from the separation of the switching contact pairs Arcs are quickly forced out of the contact zones through the antechamber into the quenching chambers.
  • the reverse arrangement of the switching contact pairs causes each other that the resulting magnetic fields in the region of each pair of switching contact the other pair of switching contact do not disturb and even amplify and thereby the arcs are significantly accelerated, so that they quickly expelled from the contact zones between each fixed contact and a movable switching contact become.
  • the first switching contact pair is arranged parallel to and rotated by 180 ° relative to the second switching contact pair. But it is also conceivable that the switching contact pairs extend at an angle of up to 10 ° to each other.
  • the switching contact pairs are next to each other in the protection switching device. Twisted in the sense of the invention means that the first fixed switching contact is located approximately next to the second movable switching contact and the first movable switching contact approximately adjacent to the second fixed switching contact.
  • the switching contact pairs of the double-breaking protective switching device are arranged such that the current flow can generate a blinding coil driving the arcs.

  • the current flow proceeds in the case of the double-breaking protective switching device after the separation of the switching contacts via the first stationary switching contact and via a first arc to the first movable switching contact. From the first movable switching contact, the current flows via the flexible electrical conductor, which is designed in particular as a strand, to the second movable switching contact. From the second movable switching contact, the current continues to flow via a second arc to the second stationary switching contact.
  • This current flow creates a blow coil driving the arcs.

  • the flexible electrical conductor in particular the stranded wire, is designed in such a way that it can follow a relative movement of the movable switching contacts relative to one another and does not break off from the movable switching contacts.
  • the ends of the flexible electrical conductor are fixedly arranged on the two movable switching contacts.
  • Such a double-breaking protection switching device is the powerful acceleration of the resulting arcs after the opening of the switch contacts by the resulting strong magnetic field or blow field and the associated rapid driving the arcs in the extinguishing chambers. Due to the rapid driving of the arcs in the quenching chamber, the residence time of the arcs between the switching contact pairs are reduced. This has the consequence that the arc load between a fixed switch contact and a movable switch contact is reduced, which is why a saving in the contact material of the switch contacts is possible.
  • Such a double-breaking protective switching device has a higher short-circuit breaking capacity than known double-breaking protective switching devices of the same size. Due to the flexible electrical conductor and the blown loop the contact points or contact plates are relieved at the switch contacts.
  • the first switching contact pair and the second switching contact pair are in an antechamber formed by the two extinguishing chambers, the prechamber being arranged mirror-inverted between the first extinguishing chamber and the first extinguishing chamber second quenching chamber is located. That is, the extinguishing chambers are not next to each other, but opposite each other. As a result, the antechamber is between the two extinguishing chambers.
  • the two switching contact pairs are at least partially in the antechamber, so that the resulting arcs can be easily driven into the proposed extinguishing chambers. Due to the mirror-inverted arrangement of the extinguishing chambers and the respective guide rails and contact horns of the extinguishing chamber are mirror-inverted and arranged parallel to each other.

  • the coil is arranged between the metal plates. That is, the coil of the protective switching device is advantageously arranged between the metal plates such that a magnetic field is created between the metal plates, which is induced by the coil on the metal plates.
  • the magnetic field generated between the metal plates causes the resulting arcs to be influenced in such a way that they are forced out of the contact zones more quickly and in the direction of the quenching chambers.
  • at least part of a metal plate covers one side of the spool core of the spool.
  • the arcs that arise after the separation of the switching contact pairs can be influenced particularly effectively by the magnetic field that arises between the metal plates, so that they are forced quickly in the direction of the respective extinguishing chambers.
