Definitions
- the invention relates to an electromagnetic actuator according to the preamble of Claim 1.
- Such actuators are widely used, especially in circuit breakers, used to detect and disable a short circuit.
- the actor or Triggers have a yoke and inside the yoke a coil that has an anchor and surround a core. If a short circuit occurs, then the armature against the Core pulled and the movement of the anchor on a contact lever or on movable Contact piece and / or transferred to a switch lock; when the movement the switching mechanism is only transmitted to the contact piece, the Contact the contact piece again after the short circuit has ended. About the switching mechanism, the movable contact piece is permanently opened.
- the object of the invention is to provide an actuator of the type mentioned, in which the trigger is pole independent and the force curve of the bondage for different Variants can be adapted.
- a bearing is rotatably mounted relative to the actuator, two-armed rocker provided, one arm of which is coupled to the anchor and on the other arm attacks one end of a fetlock spring, the other end also fixed in relation to the anchor; the rocker is arranged that the center line of the spring to the through the axis of rotation of the rocker and the Einhang BlackBerry the other end running dead center line in the tripping process pivots so that the force of holding the anchor in its rest position Spring is reduced during the triggering process.
- a further advantageous embodiment of the invention is that the rocker in is rotatably mounted on her knee.
- the axis of rotation of the rocker is located radially next to the armature.
- An arrangement further improving measure is that the pivot point the spring on the rocker crosses the dead center, so that the spring is the anchor accelerated in triggering additionally with. This acts on triggering the armature both the magnetic field generated by the coil, as well as the force the spring, which increases as the armature moves in the triggering direction.
- the rocker has approximately an L-shape, with its arm coupled to the arm about perpendicular to the central axis of the armature and its arm coupled to the spring approximately run parallel to it.
- the spring may be a compression spring or a tension spring be. In a particularly preferred arrangement, a tension spring is used.
- a further advantageous embodiment of the invention may be that the Rocker is stored at the yoke.
- the spring with its other Be hung at the end of the yoke.
- the actuator which then z as a trigger.
- B. used in a short breaker is reset by a contact spring, the one of the trigger directly actuated contact lever is assigned to sufficient in the on state Create contact pressure. If the actuator as a trigger in a circuit breaker used, then it is by means of the switch knob on the switch lock reset by the contact lever.
- the actuator according to the invention which has the reference numeral 10 in FIG. 1, is in one Housing 11 housed a circuit breaker.
- the actuator 10 has a yoke 12, one of which extends parallel to the longitudinal direction of the actuator 10 Jochsteg shows in supervision.
- Within the yoke is a coil 13 with a coil lead 14 and a coil lead 15.
- the coil 13 surrounds a Immersion anchor 16 whose ends 17 and 18 project beyond the actuator or trigger 10 axially.
- At the end 17 of the anchor has a transverse to the longitudinal axis guide plate 19 and a spaced apart retaining plate 20 through which a Gap 21 is formed, in which a first arm 22 of a rocker 23 engages, so that the first arm 22 is positively coupled to the armature 16.
- the rocker 23 has an approximately perpendicular to the first arm 22 extending second Arm 24; it is on a projection 25 of the yoke 12 in a receptacle 26 with her Rotary shaft 27 rotatably mounted.
- the second arm 24 In the embodiment of FIG. 1 jumps the second arm 24 against the release direction A before.
- an end 28 of a tension spring 29 having a center line M in one first pivot point 28 a hooked, the other end 31 on a projection 30th is also mounted on the yoke in a second pivot point 31a.
- the connecting line V between the second pivot point 31a and the rotation axis 27 is a Dead center.
