Definitions

  • the invention relates to an installation switching device with a double interruption according to the preamble of claim 1.
  • Generic installation switching devices such as motor protection switch, have at least one Polstrompfad, comprising two fixed contacts and two arranged on a movable contact bridge, movable contact pieces through which a pole switch with two contacts and double interruption is formed.
  • the contact bridge can be acted upon by a pusher in the opening direction and by a contact pressure spring in the closing direction. When switched on, the two contacts are closed. In the event of a short circuit, the contact bridge is pushed into its opening direction and the pusher is moved into its release position, in which this acts on the contact bridge opening.
  • generic installation switching devices include an electromagnetic release whose armature unlocks the Verklinkungsstelle a switching mechanism when a short-circuit current in the Polstrompfad so that this trailing the trigger from its rest position to its off position and thereby moving from its rest position to its off position effective lever the pusher holds in its release position and thus the contact bridge is permanently open against the contact pressure spring acting
  • EP-A-0079819 discloses an installation switching device according to the preamble of claim 1.
  • the active lever hurries for permanent keeping open of the contacts through the switch lock the pusher movement after. Because after unlatching the switching mechanism, it takes a certain time until the active lever is acted upon by the switching mechanism in the opening direction, and then again passes a certain amount of time until the active lever has traveled the designated as tripping distance between its rest position and its point of attack on the pusher , For design reasons, a certain trip path of the action lever is unavoidable, since the pusher and the active lever at rest require a certain amount of play.
  • the installation switching device comprises a displaceably mounted between a release position and a locking position spool, which holds the trigger in its release position in its locking position, wherein the movement of the action lever from its rest position in its off position causes a displacement of the spool from its locking position to its release position so that then the movement of the pusher is released from its release position.
  • the service switching device requires only an additional component or an additional module, namely the spool, so that an easy to install and cost-effective solution is achieved.
  • the active lever is mounted in a fixed axis of rotation, acting as a reversing lever toggle lever with a first and a second lever arm.
  • the second lever arm of the action lever in the switch-off position of the active lever, is coupled to the pusher so that it can hold it in its release position.
  • control slide is held by the pusher in its release position in the on state, and in the case of short circuit, the displacement of the spool is released into its locking position as a result of the movement of the pusher in its release position.
  • the spool can be designed as a diaphragm with an opening, wherein in the locked position, the aperture blocks the movement of the pusher from its release position out, and in the release position, the opening releases the displacement of the pusher from the triggering position out.
  • the spool or the diaphragm can be coupled to the active lever via a spring, so that the displacement of the control panel between the release and the locking position is controlled by the spring coupling with the active lever.
  • the control lever is hinged to the control lever in the rest position of the active lever in the direction of its locking position acting spring.
  • the spring may be a bent leaf spring.
  • the spool of the invention is designed as a shutter and is in the release position, the shutter is penetrated by the pusher in its opening, whereby a sliding movement of the shutter is blocked by the pusher. At the same time the shutter is in its release position when the active lever is in his Resting position is applied by mechanical coupling towards their locking position with a force.
  • the pusher As soon as the pusher is beaten into its release position by an electromagnetic release by the armature of the electromagnetic release or by an electrodynamic repulsion between the fixed and the movable contact pieces, it leaves the area of action of the aperture of the aperture and releases it. Under the influence of the mechanical coupling with the active lever, the diaphragm can now move into its locking position.
  • the spring which produces the coupling between the active lever and the control panel, a bent leaf spring.
  • the active lever can be in a very advantageous embodiment of the invention in a fixed rotational axis mounted toggle lever with a first and a second lever arm, which acts as a lever.
  • the first lever arm is acted upon by the switching mechanism, the second lever arm can hold the pusher on a shoulder in its trigger position.
  • the direction in which the impulse from the switch lock acts forms an angle with the direction of movement of the pusher.
  • the reversing lever thus deflects the direction of action of the switching mechanism in the direction of movement of the pusher.
  • FIG. 1 shows an inventive switching device 1 with a Polstrompfad 2 between an input terminal 3 and an output terminal 4. It could for example be a Polstrompfad a three-pole motor protection switch, the other two Polstrompfade are constructed accordingly.
  • the Polstrompfad 2 comprises two fixed contact pieces 5.6 and two arranged on a movable contact bridge 7 movable contacts 8.9, through which a contact point 10 is formed with double interruption.
  • the contact bridge 7 is acted upon by a contact pressure spring 11 in the closing direction, see directional arrow S.
  • a pusher 12 which engages the contact pressure spring 11 opposite side of the contact bridge 7 and on its opposite the contact pressure spring 11 narrow side carries an extension which forms a striker 20, this can be acted upon in the opening direction, see directional arrow O.
  • the Polstrompfad 2 still includes a thermal release 113 and an electromagnetic release 13 with an armature that hits the contact bridge 7 in the opening direction in the event of a short circuit current occurring in the Polstrompfad 2 due to an electrodynamic recoil over the pusher 12, indicated by the action line 14.
  • the armature of the electromagnetic release 13 in the event of a short circuit on a switching mechanism 15 and unlatched Verklinkungsstelle, indicated by the action line 16, so that the switching mechanism 15 in the unlatched state via an active lever 17, indicated by the action line 18, the pusher 12 permanently in the opening direction the contact bridge 7 acted upon.
  • thermal release 113 which also acts on the switching mechanism 15 in the case of an overcurrent, indicated by the action line 114, is known in principle.
  • the mechanical system comprising the switching mechanism 15 and the active lever 17 may be, for example, a toggle lever system with a two-stage latch.
  • the active lever 17 is designed as a double arm, the first, acted upon by the switching mechanism 15 lever arm 171 and its second, cooperating with the pusher 12 lever arm 172 form an obtuse angle with each other and are rotatably mounted in a stationary axis of rotation 173, whereby the active lever 17 as a lever acts.
  • the mechanical system just described has a certain mechanical inertia, which would take a certain amount of time, for example, 2 ms, before the active lever 17 with the free end of his second arm 172 hits the pusher 12 after the unlatching of the switching mechanism to this permanently in Opening direction apply.
  • the time to direct strike of the contact bridge 7 by the armature of the electromagnetic release 13 is much shorter, it is for example only 1 ms. This could, if no further measures are taken, happen that the contact bridge 7 already pressed back by the restoring force of the contact pressure spring 11 back to its original position in the closed position and the contact point 10 is closed again before the effective lever 17 with the free End of his second arm 172 the pusher and thus the contact bridge 7 can act permanently in the open position.
  • the pusher 12 is a total of an elongate member having approximately a cylindrical basic shape. He could also have a roughly cuboid basic shape. It comprises a main body and a striking pin 20 firmly molded thereto.
  • an upper stop 23 is formed for the contact bridge 7.
  • the pusher 12 has a shoulder 24 forming a lower stop for the free end 174 of the second lever arm 172 of the action lever 17.
  • the slide can be made in one piece with the striker 20 or the aforementioned slot as an injection molded part. But it could also consist of two parts, in the simplest case of a lower part and a screwed into this lower part cap screw, which then acts as a striking pin with guide paragraph.
  • a control slide in the form of a diaphragm 30 is mounted, which has an opening 32 which, in the closed position of the pusher 12, see FIG. 1 , the striker 20 of the pusher 12 includes.
  • the diaphragm 30 is mounted longitudinally displaceable in approximately perpendicular to the longitudinal direction of the pusher 12. In the in the FIG. 1 shown closed position of the pusher 12 is, however, a possible sliding movement of the panel 30 blocked by the striker 20 of the pusher.

  • the contact point 10 of the electrodynamic recoil breaks in the electromagnetic release 13 and the force on the pusher 12 disappears. Due to the inertia of the pusher 12, this initially continues its movement in the opening direction O. After the contact bridge 7 has reached its maximum deflection in the opening direction, it is pressed by the restoring force of the contact pressure spring 11 again in the closing direction S. However, the closing movement of the pusher 12 is now blocked by the spool 30, and the contact point 10th stays open. During this entire time, the active lever 17 remains in its rest position due to the mechanical inertia of the pawl mechanism of the switching mechanism 15 and the active lever 17 comprehensive mechanical system.
  • the switching mechanism After expiration of the delay time caused by inertia, the switching mechanism after releasing its latching mechanism via a known mechanical device exerts a force K on the first lever arm 171 of the action lever 17, see FIG. 4 , whereby it is rotated clockwise relative to its starting position.

  • the mechanical coupling between the diaphragm 30 and the active lever 17 could also be realized so that in the rest position of the active lever 17, the diaphragm 30 is acted upon in a direction away from the active lever 17 direction.
  • the timing in the interaction between the aperture 30, the pusher 12 and the active lever 17 could also be designed so that the striking pin 20 penetrates a small distance into the opening 32 before the active lever 17 has been pivoted clockwise so far that its second Lever arm holds the pusher 12 permanently in its trigger position.
  • FIGS. 5 to 7 This embodiment is different from that of FIGS. 1 to 4 in that instead of a control panel on the underside of the second lever arm 172 of the active lever 17, a spring-biased slide 1030 is used as a control slide, which causes the locking of the pusher.
