Definitions
- the invention relates to a circuit breaker according to the preamble of claim 1.
- Circuit breakers are known in particular as low-voltage circuit breakers. They have switching contacts, which are opened via a switching shaft.
- the switching shaft is actuated by means of a trip slider on the release shaft of a switching mechanism.
- the trip valve is part of the shunt release of the circuit breaker.
- the shunt release on an electrical see coil, in which extends an anchor, which is often designed as a longitudinally movable iron core anchor. When triggered, the armature is pulled into the coil by magnetic forces of attraction.
- the object of the invention is to propose a technically simple circuit breaker, which can be used without energy storage, e.g. in the form of a spring store.
- the solution provides that in the coil for increasing the attraction forces arranged as a stop for the anchor stationary counter-anchor is arranged and that to increase the displacement of the trigger slide, the movement of the armature is transmitted by a mechanism to the movement of the trigger slide.
- the large forces that have occurred in this displacement range are used to sufficiently move the release slide while the forces (triggering forces) are still relatively high. Only this allows a direct actuation of the trip shaft and thus the shift shaft. Quasi the disadvantage of a pulling magnetic coil is corrected, namely that the magnetic force decreases disproportionately with the distance from the stop of the counter-anchor.
- the mechanism ensures a sufficiently large travel of the release lever with a small armature stroke.
- a simple and effective embodiment provides that the armature and the counter-anchor facing each other have flat end faces.
- Fig. 1 shows the trigger of a circuit breaker
- Fig. 2 shows the trigger of FIG. 1 in a sectional view
- Fig. 3 shows force-displacement curves of the trigger according to Fig. 2.
- Fig. 1 shows a trigger 1 of a not further shown
- Circuit breaker which is provided with switching contacts, which are opened via a switching shaft.
- the actuation of the switching shaft via a release shaft of a switching mechanism, not shown.
- a release slide 2 is displaced for this purpose.
- the trigger 1 is shown in Figure 1 without housing. it has a U-shaped ferromagnetic component 3, in which a Coil 4 is arranged.
- An armature 5 (see Fig. 2) extends in the coil 4, of which only the armature disk 6 located outside the U-shaped component 3 can be seen in FIG.
- the armature disk 6 moves two mutually cooperating release levers (transmission lever 7, deflection lever 8), which together form a mechanism 9 which transmits the longitudinal movement (longitudinal displacement) of the armature 5 into a longitudinal displacement of the release slider 2. If the armature 5 is pulled into the coil 4, the trigger slide 2 is displaced in the opposite direction.
- Fig. 2 shows the trigger 1 as a longitudinal section in which the armature 5 is opposite to a counter-anchor 10.
- This counter-anchor 10 has the task to strengthen the magnetic attraction forces on the anchor and to form a stop for the armature 5.
- the end faces 11, 12 are shown spaced from each other, that is, between the end faces 11, 12 is a gap 13.
- the transmission lever 7 is mounted on a slot 14 on the armature 5, to its support off the housing of the trigger. 1 serves a pivot axis 15 about which the transmission lever 7 is strig. When pivoting the transmission lever 7 (by the armature 5), a bolt 16 fixed to the transmission lever 7 moves in the slot 14 upwards or downwards.
- the pivoting movement of the transmission lever 7 is transmitted to the lever 8 by means of a link 17.
- the gate is in the transmission lever 7 in the form of a correspondingly shaped recess into which engages a pin 18 attached to the upper end of the transmission lever 7.
- the deflection lever 8 designed as a double lever is rotatably mounted on an axle 19. Its lower (in Fig. 2) end of the lever presses against and shifts the trigger slide 2 in its longitudinal direction when the armature 5 is pulled into the coil 4.
- the armature 5 moves toward the stop 11 due to the magnetic attraction forces.
- the armature 5 thereby pulls the transmission lever 7 in Fig. 2 to the left, which in turn pulls the lever 8 to the left. This presses in Fig.
- FIG. 3 shows the force-displacement curve 20 of the armature 5, the desired force-displacement curve 21 of the trigger slide 2 and the scoring 17 achieved by force path 22 of the trigger slide 2.
- F is the force on the path S.
- Fmax is the maximum armature force
- Fs and Ss are the target value for the force on the trigger slide 2 and the target path of the trigger slider 2 as target values, respectively.
- the link 17 must be shaped accordingly in order to obtain the almost constant force over the entire displacement path.
- the force-displacement curve 20 of the armature 5 in FIG. 3 shows that with approach of the armature 5 to the counter-anchor 10 per unit distance disproportionately (square) increasing attraction.
