Definitions

  • the invention relates to an electromagnetic release a coil, an anchor, one interacting with it, in the coil movable plunger, one with the coil electrically connected magnetic yoke through which the plunger is guided or the ram is passed, and a spring acting on the armature with a force.
  • a trigger is, for example, from the DE 101 26 851 C1 known.
  • the electromagnetic release known from DE 101 26 851 C1 especially for a circuit breaker a magnetic core formed in one piece with a magnetic yoke on which is arranged within the cross section of the trip coil is and with a central opening for implementation a plunger connected to a movable anchor is.
  • a circuit breaker such as a circuit breaker
  • a relatively narrow cross section of a coil Magnetic release is for a given cross-sectional area accessible through a non-circular coil cross-section, but this construction area is compared to coils with a circular one Cross-section more complex to manufacture.
  • the invention has for its object an electromagnetic Triggers for a circuit breaker, especially circuit breakers, indicate which one with simple construction, especially with a circular coil cross-section, is particularly narrow.
  • this electromagnetic release demonstrates Submersible anchor systems known components coil, magnetic yoke, Anchor, plunger and spring open.
  • the magnetic yoke or Magnetic core is like a conventional submersible anchor along the Slidable axis. In this way there are advantages regarding the impact of the anchor, which, for example cannot be used with hinged anchor systems.
  • the diameter of the trigger coil can be particularly small because the "core" of the magnetic yoke almost to the outside next to the coil is shifted.
  • the magnetic yoke 2 preferably has ones arranged outside the coil Yoke legs on, which also with two outside the coil is arranged at least approximately symmetrically to the coil axis Anchor legs work together. This makes two Air gaps between an anchor leg and one Yoke leg formed, which the impact of the anchor in Compared to training with only one air gap strengthen. This also ensures that the armature when the magnetic trigger responds exactly in the direction the coil axis is accelerated.
  • the anchor with a force against the release direction acting spring is preferred in a space-saving manner formed as a coil spring, which concentrically concentrates the plunger surrounds.
  • the spring can either at least partially inside the coil or completely outside the coil be arranged.
  • the first type of construction has the advantage that a relatively long coil spring can be used, which provides a correspondingly long travel while
  • the second construction is characterized by the fact that the Diameter of the coil can be chosen even smaller. In any case, a simple plug-in assembly of the individual Parts of the trigger possible.
  • the anchor is in one piece with the plunger, preferably as a stamped part.
  • a special one rational production is made possible by the fact that this combined component is completely flat.
  • a second alternative is the anchor and the plunger as separate components interacting on stop surfaces educated.
  • this design has the advantage that different materials for the anchor on the one hand and the Plunger on the other hand, in particular a plastic for the plunger, can be used.
  • a Trigger element in particular a bimetallic strip to provide. The typically much lower forces than that Bimetallic strips that produce magnetic releases must be activated of the plunger does not have the force of the prestressing the magnet armature Overcome spring.
  • a circuit breaker typically has one on it Magnetic yoke connecting the electromagnetic trigger Arc guide rail on. If such an arc guide rail if the trigger is provided, this is preferred arranged such that there is between this and the trigger coil the movable anchor leg or one of the movable Anchor leg is located. The anchor leg is thus well protected from the effects of an arc.
  • the advantage of the invention is in particular that by shifting an air gap in principle the kind of an immersion anchor system trained electromagnetic A trigger from the coil inside next to the coil is a special one
  • the trigger is narrow in structure.
  • the trigger 1 shows an electromagnetic trigger 1 of a Miniature circuit breaker, which in the same or modified Execution also with a motor protection switch, circuit breaker, Contactor or relay could be used.
  • Essential components of the trigger 1 are a coil 2, a magnetic yoke 3 and an armature 4 with a plunger 5, which in this embodiment in one piece with the armature 4 is made.
  • the plunger 5 moves in the actuation direction R and thus opens Switch lock, not shown.
  • the anchor 4 is opposite the actuation direction R by the force of a coil spring trained spring 6, which for the most part lies within the coil 2 and the plunger 5 concentrically surrounds.
  • the magnetic yoke 3 has two outside on the coil 2 Yoke legs 9, 10, each forming one Air gap 11, 12 each an arm leg 13, 14 of armature 4 are opposite. While the magnetic yoke 3 with the yoke legs 9,10 is asymmetrical, the armature 4 is approximately symmetrical in E-shape, the plunger 5 as middle E-leg is arranged along the coil axis A. and the magnetic legs 13, 14 form the outer E-legs.
  • the symmetrical structure of the armature 4 ensures that when the trigger 1 responds, a force on the Tappet 5 only acts in the actuation direction R. A Redirection of the direction of movement, such as with hinged anchor systems, not necessary.
  • the impact of the ram 5 can directly to open a formed on the contact piece 7 Contact can be used.
  • 2 and 4 in particular illustrate the very narrow design of the trigger 12 with a width B, which is both the outer diameter of the coil 2 and the maximum width of the magnetic yoke 3, and a height H that is approximately three times the width B.
  • the width B is preferably less than 9 mm, so that two triggers 1 side by side in an 18 mm wide housing a modular device can be installed.
  • the magnetic yoke 3 is manufactured as a stamped and bent part, which a connection point 15 electrically connected to the coil 2 is.
  • the anchor 4 including the plunger 5 and the Arc guide rail 8 are not bent stamped parts manufactured. Overall, this is a very manufacturing-friendly Construction of the trigger 1 given.
  • FIG. 3 shows a housing shell 16, which bearings 17 for the armature 4 and the through an opening 18 of the Magnet yoke 3 guided plunger 5 forms.
  • the magnetic yoke can also 3 be mounted directly in the housing shell 16. Instead of the guidance of the plunger 5 through the opening 18 can on the a corresponding bulge, for example of the magnetic yoke 3 can be provided so that the plunger 5 on Magnet yoke 5 is passed.
  • FIGS 1 to 5 show a further embodiment of a electromagnetic trigger 1.
  • Plunger 5 a separate from the anchor 4 and relative to this movable component.
  • the in this case outside the Coil 2 arranged spring 6 acts only on the Anchor 4 with a force.
  • the plunger 5, however, can be used without actuation the armature 4 in the actuation direction R practically without Force is postponed.
  • This decoupling of the ram 5 from anchor 4 is particularly suitable for actuation of the plunger 5 not only electromagnetically, but also by a second trigger mechanism, not shown, in particular a bimetallic release.
  • the plunger 5 is for this purpose on a base surface 19 of the armature which is curved in this case 4 passed and has an actuating surface at the end 20 on which a bimetal element can attack which typically compared to the short circuit on the Armature 4 acting magnetic force only a relatively small Provides strength.
  • the plunger 5 can thus through the bimetallic element be moved in the actuation direction R and thus trigger a symbolically represented switching element 21.
  • the trigger 1 thus serves not only as an electromagnetic i.e. instantly appealing trigger but also at the same time as an essential part of a delayed circuit breaker.
  • Plunger 5 made of plastic or provided on anchor 4.
