Definitions

  • the invention relates to a low-voltage switching device with an electromagnetic drive with a coil, a fixed yoke and an armature that can be moved relative to the yoke, and with a contact system consisting of a fixed contact carrier and a movable contact carrier arranged opposite thereto, with the movable contact carrier being acted upon by a contact load spring .
  • Electrical switching devices are required to switch and conduct electrical currents up to a specified level without interference. To do this, they have a drive that closes the contacts with a specified contact force, keeps them closed and opens them again.
  • the DE 42 16 080 A1 a solution in which a ferromagnetic body is arranged at a small distance next to the current-carrying section of a contact spring on the side of the mating contact.
  • the magnetic attraction is used, which is the magnetic field of the over exerts the contact of flowing current on a ferromagnetic body.
  • the pressure on the contacts is increased.
  • the FR 2 793 090 A1 describes a solution in which a U-shaped ferromagnetic element is placed around the moving contact. The flow of current in the moving contact induces a magnetic flux in the ferromagnetic element, which in turn exerts a contact-closing force on the moving contact.
  • Both the DE 42 16 080 A1 as well as the FR 2 793 090 A1 have the disadvantage that as the current flowing through the contact pieces increases, the electromagnetic contact-closing forces increase sharply, making it increasingly difficult to separate the contacts when there is an opening command.
  • a contact switching device between at least one fixed contact piece and a movable switching arm comprises a reinforcing magnetic core which interacts with the movable switching arm and a compensating magnetic core which is connected to at least one fixed conductor of the Switching device interacts.
  • the boosting magnetic core and the compensation magnetic core are mounted opposite to each other on a movable base. When an electric current flows in the shift movable arm, a boost magnetic flux flows in the boost magnetic core and generates an attractive force between the shift movable arm and the movable base.
  • the compensating magnetic core acts on the other side of the movable base, which also exerts a force on the movable base which is directed counter to the force exerted by the reinforcing magnetic core.
  • the boosting force is greater than the compensating force.
  • the boosting force is smaller than the compensating force.
  • the FR 2 829 869 A1 has the disadvantage that, on the one hand, it requires complex mechanics and, on the other hand, it is just like that DE 103 43 005 B4 that it offers no solution to the problem of switching contact erosion. Furthermore, the EP 2 960 917 A1 an arc quenching chamber.
  • the object of the present invention is to provide a low-voltage switching device with a switch that is easy to implement specify electromagnetic contact load support.
  • this object is achieved by a low-voltage switching device with an electromagnetic drive with a coil, a fixed yoke and an armature that can be moved relative to the yoke, and with a contact system made up of a fixed contact carrier and a movable contact carrier arranged opposite thereto, the movable contact carrier being controlled by a Contact load spring is applied.
  • the invention is characterized in that a first means for electromagnetic contact load support is positioned on the fixedly positioned contact carrier.
  • two means for electromagnetic contact load support are preferably used. These are, on the one hand, a U-shaped ferromagnetic sheet and, on the other hand, a U-shaped spring plate. A magnetic flux is induced in each of the two U-shaped ferromagnetic elements. This causes a relatively high electromagnetic excitation even with small currents through the contact carrier or through the bridge, so that a relatively large attractive force is formed between the pole faces.
  • the pole faces themselves are kept relatively small and separated from each other by an air gap.
  • the magnetic circuit saturates very quickly, so the increase in force at very high currents is relatively small. This is important so that the switching contacts can still be separated in the event of overcurrents, for example in the event of an overload or short circuit.
  • the inclined position of the pole faces can compensate for a greater travel loss due to contact wear. It can also be used to compensate for tolerances in the assignment of the pole faces to the contacts.
  • the ferromagnetic, U-shaped U-plate is attached to the contact carrier in such a way that the current flowing in the contact carrier induces a magnetic flux in the U-plate. There are pole faces on the U plate.
  • a ferromagnetic spring plate with end faces and pole faces is attached to the bridge.
  • the end faces together with the pole faces form U-shaped sections that protrude around the bridge, with the opening of the U facing the fixed contact carrier or U-plate.
  • a magnetic flux is induced in each of the U-shaped sections on the spring plate.
  • the magnetic fluxes in the U-plate and in the U-shaped section are polarized in such a way that a magnetic attraction force is created between the pole faces on the U-plate and in the pole faces on the spring plate, with the pole faces at an angle of approx 45° are arranged.
  • the arrangements or geometries of the contact carrier, bridge, fixed contact, movable contact, U-shaped section on the spring plate and U-plate are dimensioned in such a way that an air gap remains between the pole faces when the low-voltage switching device is switched on. Due to wear on the contacts, the bridge and the spring plate move closer to the contact carrier or U-plate. On the one hand, this means that the air gap between the pole faces is smaller and to increase the magnetic attraction. On the other hand, the distance between the contact carrier and the bridge is also smaller and the repelling forces between the bridge and the contact carrier are therefore greater.
  • the invention also provides that U-shaped ferromagnetic elements in the form of the spring plate and the U-plate are arranged both around the movable bridge and around the stationary contact carrier, the pole faces of which are directed towards one another when switched on and which move when current flows attract electromagnetically through the contact carrier and the bridge.
  • the geometries of the ferromagnetic elements mentioned are assigned to the contacts in such a way that an air gap remains between the pole faces when the contacts touch. This air gap between the pole faces still exists when the contact material intended for the service life of the low-voltage switching device is worn out.
  • the opposing pole faces on the spring plate or on the U-plate are not perpendicular to the contact-closing-opening direction, but are at an angle of 45°, for example.
  • the ferromagnetic elements including the air gap between the pole faces, are dimensioned in such a way that the electromagnetic contact load support is less than or equal to the contact load that is applied via the contact load spring. Furthermore, the ferromagnetic elements, including the air gap between the pole faces, are dimensioned in such a way that the increase in electromagnetic force due to the decreasing air gap is approximately the same as the increase in the repulsive forces between the contact carrier and the bridge due to the decreasing distance.
  • the first means is a U-shaped, ferromagnetic sheet metal with two opposing pole faces and a central area connecting the pole faces.
  • pole faces of the U-shaped ferromagnetic sheet are formed like wings.
  • the second means for electromagnetic contact load support is a U-shaped, ferromagnetic spring plate with two opposing legs and a central region connecting the two legs.
