Definitions

  • the invention relates to a protective switching device, in particular a circuit breaker, which has an input terminal and an output terminal, which are designed for contacting with an electrical line.
  • the protective switching device has a switching contact, which has a stationary fixed contact and a movably arranged movable contact, which are designed such that forms an arc between the moving contact and the fixed contact when opening the current-carrying switching contact.
  • the protective switching device has a short-circuit release system with a coil and a relative thereto movably mounted release means, which is designed to act in the case of triggering on the moving contact to cause an opening of the switching contact.
  • the invention further relates to a magnetic yoke, which is arranged adjacent to the coil of the short-circuit release system and serves to reinforce the magnetic effect of the coil on the triggering means in the event of triggering.
  • Circuit breakers are designed especially for high currents.
  • a circuit breaker (so-called LS switch) is an overcurrent protection device used in electrical installations 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 electrical equipment from overload, for example, from damage to the cables due to excessive heating due to excessive electrical current.
  • Circuit breakers and circuit breakers are used in particular as switching and safety elements in electrical energy supply networks and serve the monitoring and protection of an electrical circuit.
  • the protective switching device is electrically connected via two terminals with an electrical line of the circuit to be monitored in order to interrupt the electrical current in the respective line when needed.
  • the protective switching device in this case has a switching contact with a stationary fixed contact and a movable relative to moving contact.
  • the moving contact is actuated via a switching mechanism of the protective switching device, so that the switching contact can be opened and closed. In this way, when a predefined state, for example a short circuit or an electrical overload, occurs, the switching contact is opened in order to disconnect the monitored circuit from the electrical line network.
  • Such protective switching devices are known in the field of low-voltage technology as DIN rail mounted devices.
  • a so-called fixed contact piece is arranged on the fixed contact in an electrically conductive manner, which cooperates with a moving contact piece arranged in an electrically conductive manner on the moving contact. If the switching contact is opened at a time when an electric current flows via the switching contact, then an arc is formed when the switching contact between the fixed contact piece and the moving contact piece is removed therefrom.
  • conventional protective switching devices have a so-called quenching chamber with a multiplicity of splitter plates arranged next to one another and spaced apart from one another. If the arc is driven into the quenching chamber, it divides when hitting the quenching plates into several partial arcs, which then burn in series between the individual quenching plates. The multiple, electrically sequentially connected in succession partial arcs result in total to a higher arc voltage, which leads to a faster extinction of the arc as a result.
  • a standing between the fixed contact piece and the BewegCount Swiss arc leads to a so-called contact erosion, i. for a removal of material on the fixed contact piece as well as on the moving contact piece.
  • contact erosion leads to increased electrical resistance.
  • the contact erosion leads to contamination of the contact pieces with microparticles, which in turn leads to a higher tendency to weld of fixed contact piece and moving contact piece.
  • a contact erosion leads to damage of the protective switching device and is therefore to be avoided as much as possible. Therefore, the arc should be driven as quickly as possible away from the lying between the fixed contact and moving contact contact area in the quenching chamber and deleted.
  • the protective switching device which is designed in particular as a circuit breaker, has an input terminal and an output terminal, which are designed for contacting the protective switching device with an electrical line. Furthermore, the protective switching device has a switching contact, which in turn has a stationary fixed contact and a movable relative to movable contact, which are designed such that forms an arc between the moving contact and the fixed contact when opening the current-carrying switching contact.

Furthermore, the fixed contact is formed by a fixed contact region of the magnetic yoke, which is integrally connected at its first end to the coupling region, and the second end is formed as a free end. Further, the magnetic yoke on a quenching chamber region, which is integrally connected to the coupling region and forms a bypass current path, which in the event of an arc due to an opening of the switching contact after a commutation of the arc is energized from the fixed contact region to the quenching chamber region.
  • the protective switching device has a switching contact, consisting of a fixed contact and a movable relative to movable contact on.
  • a separate fixed contact piece may be electrically conductively attached to the fixed contact, which cooperates with a moving contact arranged on the moving contact moving contact piece.
  • the moving contact can be actuated via a switching mechanism of the protective switching device, the fixed contact is formed as part of the magnetic yoke of the short-circuit release system of the protective switching device, the so-called fixed contact region of the magnetic yoke.
  • the action of the triggering means on the moving contact can be effected directly, but also indirectly - for example, by an action of the triggering means on the switching mechanism, which then in turn causes actuation of the moving contact and thus opening of the switching contact. Both possibilities, both indirect and direct action on the moving contact, can be combined.
  • the design of the second end of the fixed contact area as a free end causes the fixed contact, although stationary, but not rigidly arranged in the housing of the protective device.
  • the design of the second end of the fixed contact area as free end to the fact that in the case of a short circuit, the direct current flow is interrupted after the commutation of the arc to the quenching chamber area.
  • the load duration acting on the fixed contact region due to the high short-circuit current can thereby be significantly reduced, so that damage due to high temperatures due to the short-circuit current is avoided.
  • the magnetic yoke is integrally formed and therefore - compared to multi-part designs - relatively inexpensive to produce.
  • the coupling region serves, for example, the coupling of the magnetic yoke to the coil of the short-circuit release system.
  • This coupling can be both electrical, but also magnetic nature.
  • a mechanical coupling with a housing of the protective switching device can be realized.
  • the coupling region has an opening for the implementation of the triggering means. Since the magnetic yoke - and in particular the coupling region - is at least partially arranged between the short-circuit release system and the moving contact, the opening formed in the coupling region of the magnetic yoke represents a simple, space-saving and cost-effective means for acting on the moving contact with the aid of the triggering means Opening the switch contact to effect.
  • the coupling region is shaped such that a magnetic core is formed, which is at least partially received in the coil in the mounted state.
  • the magnetic core serves to significantly enhance the magnetic effect of the trip coil. This effect can be improved, ie increased, when the magnetic core is at least partially immersed in the coil.
  • the coupling region of the magnetic coupling of the magnetic yoke is used with the coil of Kur gleichauslettessystems.
  • the coupling region is designed for fastening a magnetic core, which is accommodated in the assembled state at least partially in the coil.
  • the magnetic core can also be mounted as a separate component on the coupling region of the magnetic yoke. This has the advantage that the magnetic core can be made more massive, which increases its magnetic effect.
  • a suitable material can be selected for this purpose without the design of the magnetic yoke having to be taken into account. This leads to significantly higher degrees of freedom with regard to the structural design of the protective switching device, which is particularly advantageous in high-end devices.
  • the magnetic core can be connected to the coupling region by means of welding or riveting.
  • Welding or riveting represent simple and cost-effective method for producing a connection of the magnetic core with the coupling region of the magnetic yoke.

  • the contact horn which is oriented towards the quenching chamber area at the free end, the arc produced during the opening of the energized switching contact is pulled away from the switching contact in the direction of the quenching chamber or the prechamber region arranged in front of the quenching chamber.
  • the arc commutes from the fixed contact region to the quenching chamber region of the magnetic yoke. From this point on, the electric current thus no longer flows through the fixed contact area, but via the bypass current path which is now energized. In this way, a re-ignition of the arc in the contact area as well as excessive heating - and thus a possible damage to the fixed contact area - effectively avoided.

  • the magnetic yoke according to the invention has several advantages. On the one hand, due to its one-piece design, the magnetic yoke can be produced relatively inexpensively compared to multi-part embodiments. Furthermore, in the magnetic yoke according to the invention several - originally designed as individual components - integrated: By merging the original magnetic yoke with the original fixed contact area to a single component, the number of parts is significantly reduced, which has an advantageous effect on the manufacturing and assembly costs of the protective device.

  • the design of the second end of the fixed contact region as a free end means that in the case of a short circuit, the direct current flow is interrupted via the fixed contact region after commutation of the arc to the quenching chamber region.
  • the energy input acting on the fixed contact area due to the high short-circuit current can thereby be significantly reduced since the fixed contact area is not permanently, i. is energized until the final extinction of the arc in the quenching chamber, but only until the commutation of the arc from the fixed contact area to the quenching chamber area. In this way damage to the fixed contact region is effectively prevented by the high temperature development associated with the short-circuit current.
