Definitions
- the invention relates to an electromagnetic actuator according to the preamble of the claim 1.
- Such actuators are used on a large scale, especially in circuit breakers, used to detect a short circuit and switch it off.
- the actuator or Triggers have a yoke and inside the yoke a coil that has an armature and surrounds a nucleus. If a short circuit occurs, the anchor will be against the core pulled and the movement of the armature on a contact lever or on movable Transfer contact piece and / or to a key switch; when the movement of the Switch lock is only transferred to the contact piece, the contact piece return to the on position after the short circuit has ended; about the Switch lock, the movable contact piece is opened permanently.
- a captive magnet is used to set the tripping point or the tripping current used; for magnetic releases there are also arrangements with an external one Cuff spring.
- the magnetic triggers which serve as short interrupters, normally have a magnet for captivation.
- the disadvantage here is the high cost of the magnet; the holding force of the magnet is limited by its geometry, and the response value is polarity dependent. Furthermore, the force curve cannot be changed, since practically no force acts on the anchor after the magnet has been torn off.
- the object of the invention is to provide an actuator of the type mentioned at which the release is independent of the pole and the force course of the bondage for different Variants can be adjusted.
- rocker in her knee is rotatably mounted.
- the axis of rotation of the rocker is located radially next to the anchor.
- the seesaw is approximately L-shaped, with its arm coupled to the anchor approximately vertical approximately parallel to the central axis of the armature and its arm coupled with the spring to get lost.
- the anchor jumps so that the dead center position can be reached or exceeded against the direction of force of the spring.
- Another advantageous embodiment of the invention may consist in that the The rocker is mounted on the yoke, in the same way the spring can with its other Be attached to the yoke at the end.
- the actuator which is then used as a trigger z. B. used in a breaker is reset by a contact pressure spring that is operated directly by the trigger Contact lever is assigned to sufficient when switched on To generate contact pressure.
- the actuator is used as a trigger in a circuit breaker used, then it is by means of the switch toggle over the switch lock of the contact lever deferred.
- the actuator according to the invention which has the reference number 10 in FIG. 1, is in one Housing 11 of a circuit breaker housed.
- the actuator 10 has a Yoke 12, one of which has a yoke web running parallel to the longitudinal direction of the actuator 10 shows up under supervision.
- Inside the yoke there is a coil 13 with a coil feed line 14 and a coil lead 15.
- the coil 13 surrounds a plunger 16, the ends 17 and 18 of which axially project beyond the actuator or trigger 10.
- the armature has a guide plate 19 extending transversely to the longitudinal axis and an in Distance to this holding plate 20, through which an intermediate space 21 is formed, into which a first arm 22 of a rocker 23 engages, so that the first arm 22 with the anchor 16 is positively coupled.
- the rocker 23 has a second one running approximately perpendicular to the first arm 22 Arm 24; it is on a projection 25 of the yoke 12 in a receptacle 26 with it Rotation axis 27 rotatably mounted.
- At the free end of the second Armes 24 is hooked one end 28 of a tension spring 29, the other end 31 of a projection 30 is also attached to the yoke.
- the connecting line V between the attachment point 30, 31 and the axis of rotation 27 is a dead center line.
- the spring 29 acts there is the dead center line V here on the left, a force on the one hand on the second arm 24, which the rocker 23 tries to turn clockwise, and on the other hand over the arm 22 a force on the armature 16, whereby the armature in the ready to trip shown in Fig. 1 Position is held.
- the spring acts on the rocker a torque that runs counterclockwise, so that the switch-off movement of the armature is additionally accelerated by the force of the spring.
