Definitions

  • the invention relates to a DC arc extinguishing device for an electromechanical DC switching device, comprising an arc quenching chamber, comprising a plurality of spaced apart and mutually parallel quenching plates, as well as a directly before the Lichtbogenlösch ⁇ hunt arranged arc formation chamber, which on both sides of a longitudinal Having ⁇ ffen ⁇ ebene arranged permanent magnets. Furthermore, the invention relates to a DC electromechanical switching device, in particular a DC circuit breaker, with such a DC arc extinguishing device.
  • switching device is understood to include both protective switching devices, such as circuit breakers, circuit breakers or residual current circuit breakers, as well as switching devices without their own protective function, such as load switch, disconnector or switch disconnector.
  • 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 systems from overload, for example, from damage to the electrical cables due to excessive heating as a result of excessive electrical current. They are designed to automatically switch off a circuit to be monitored in the event of a short circuit or when an overload occurs and thus separate it from the rest of the network.
  • Circuit breakers and circuit breakers are therefore particularly used as switching and security elements for monitoring and securing an electrical circuit in electrical energy supply networks.
  • Circuit breaker are from the publications DE 10 2015 217 704 A1 .
  • DE 10 2013 211 539 A1 or EP 2 685 482 B1 in principle already known.
  • Residual current circuit breakers are for example from the publications EP 0 957 558 A2 . DE 10 2014 208 036 A1 or DE 10 2014 202 485 A1 previously known.
  • switching devices without their own protective function are known from the prior art. These include, for example, the so-called load switch, disconnector or switch disconnectors. Among the latter switching devices are understood, which meet in terms of their functionality, both the requirements of a load switch - the switching under electrical load - and the requirements placed on a circuit breaker - the almost powerless separation of electrical system parts. Switch-disconnectors are suitable for switching off large electrical currents, but their switching capacity is generally lower than that of the circuit-breakers. In low-voltage networks, switch-disconnectors are used, for example, to interrupt main circuits in the region of the main distribution, the switching power usually being in the range between 40 and 63 kA. In accordance with DIN EN 60947-3, both switch disconnectors, as well as load and disconnect switches depending on their respective performance in so-called utilization categories, in which, depending on the application, different requirements are defined divided.
  • the switching devices mentioned above are usually electrically conductively connected via two terminals to an electrical line of the circuit to be monitored in order to interrupt the electrical current in the respective line when required.
  • the switching device has a switching contact with a fixed contact element - the so-called fixed contact - and a relatively movable contact element - the so-called moving contact - on.
  • the moving contact makes contact with the fixed contact.
  • To separate the current flow of the moving contact is moved away from the fixed contact.
  • the moving contact is actuated, for example via a switching mechanism of the switching device, so that the switching contact can be opened and closed.
  • a protective switching device can thus be opened when a predefined state, such as a short circuit or overload, the switching contact to separate the monitored circuit from the electrical network.
  • Such switching devices are known in the field of low-voltage technology as DIN rail mounted devices.
  • the interruption of the current flow by opening the switch contact leads at least briefly to a voltage flashover between the fixed and the movable contact element, since the distance during the separation process of the contact elements for isolation is not sufficient. If there is a gas between the two switching contacts, this is ionized by the flashover with a correspondingly high voltage difference between the contact elements, an arc being formed due to the gas discharge.
  • conventional switching devices have an arc extinguishing device, for example a so-called Extinguishing chamber with a plurality of juxtaposed and spaced apart quenching plates, on.
  • the arc extinguishing device may consist only of a plurality of mutually parallel extinguishing or cooling plates.
  • the arc is driven in the direction of the arc extinguishing device, so it divides when hitting the quenching plates in a plurality of partial arcs, which then connected in series burn between the quenching plates.
  • the multiple, electrically sequentially connected in succession partial arcs in total lead to a higher arc voltage, which leads to a faster extinction of the arc as a result.
  • a quick extinguishing is essential to keep the energy associated with the arc energy input into the housing of the switching device as low as possible in order to avoid damage to the switching device and the electrical installation.
  • switching devices in particular those which are intended for use in alternating current networks, often have a so-called blowing loop.
  • This is a conductor loop, which is arranged in the region of the switch contact and acts like an electric coil. This can be energized permanently, but is meaningful way electrically connected so that it is additionally energized only at an occurring by opening the switch contact arc.
  • the resulting from the energized Blasschleife electromagnetic field is oriented such that it exerts a Lorentz force on the arc, which forces the arc away from the switching contact in the direction of the arc extinguishing device.
  • Corresponding switching devices are, for example, from the patent DE 2 841 004 B1 or from the published patent application DE 3 333 792 A1 known.
  • blown loops have the disadvantage that they generate only a small electromagnetic field at low currents, so that the resulting electromagnetic force on the arc is comparatively small. Your full Therefore, they develop their effect only at high currents, as they occur, for example, in the case of a short circuit.
  • DC switching devices In switching devices for DC applications, so-called DC switching devices, especially the deletion of electrical currents less than 150 amps is problematic, since the dynamic driving force or the arc of the arc at these currents are not high enough to drive the arc in the arc extinguishing chamber and to keep him there and extinguish it.
  • permanent magnets are used in the usual way. This can be achieved, for example, by arranging a permanent magnet on each side of the arc formation chamber.
  • a permanent magnet By means of a permanent magnet, a comparatively high magnetic field strength can be realized, however, the magnetic field generated by a permanent magnet is temporally constant with respect to its orientation direction, so when mounting the permanent magnet on the correct for each electric current flow direction magnetic polarity is to ensure a corresponding force on the Create arc in the desired direction.
  • magnetic polarity is to ensure a corresponding force on the Create arc in the desired direction.
  • permanent magnets are generally not used to influence the arc in switching devices.
  • the magnetic field generated by the permanent magnets is usually symmetrical and oriented so that the arc - with the correct polarity - is driven away from the switching contact in a straight direction in the arc extinguishing chamber. It may happen that the magnetic field in the region of the usual for arc extinguishing chambers V-shaped notch of the quenching plates is weak due to the distance to the permanent magnet, so that the force acting on the arc in the area immediately before entering the arc extinguishing chamber is low , In these cases, it may happen that the arc is much slower in the Arc quenching chamber enters, which has a higher energy input result, or in the worst case even stops in front of the arc extinguishing chamber and does not extinguish.
  • DC switching devices are known from the prior art, which generate an asymmetric magnetic field by means of permanent magnets, whereby the arc driven not only in the direction of the arc extinguishing chamber, but also transversely is deflected to this direction of movement to drive the arc off-center in the V-shaped notch of the quenching plates or the arc extinguishing chamber.
  • Such DC switching devices with asymmetric magnetic field for example, from the European patents EP 2 061 051 B1 .
