Definitions

  • the invention relates to an additional switch for mounting on a circuit breaker with manually or automatically switchable contact devices controlled by the switching mechanism of the circuit breaker in conjunction with an operating knob.
  • auxiliary and signal switch are arranged in a single housing chamber and the common drive by means of a beaufschlag from the switching mechanism of the circuit breaker - th, about a fixed pivot point pivotally mounted clutch lever. Furthermore, control elements in operative connection with the clutch lever and the control knob are provided in the housing chamber.
  • the invention has for its object to simplify the known arrangement in its mechanical structure even further and to design an additional switch so that it can be used either as an auxiliary switch or as a signal switch and can only be adjusted accordingly after completion or if necessary subsequently with simple means.
  • the invention has the advantage that, if necessary, the customer can also manufacture two different devices from one device type as required. This makes warehousing reduced and simplified. Furthermore, only a small space requirement is required in the direction of the pole pitch. No major changes need to be made to the miniature circuit breaker and its switching mechanism, since the coupling and transmission means which are customary in multipole miniature circuit breakers serve as control elements.
  • the attached auxiliary switch does not cause any forces that adversely affect the adjacent circuit breaker when it is switched on again.
  • the additional switch is used as a signal switch, very simple control elements are provided in the construction, which ensure reliable operation.
  • a switching position indicator corresponding to the use as a signal switch or as an auxiliary switch is realized with simple means.
  • the additional switch has in a housing chamber 1, which is closed by a cover 2 which is only partially shown, two contact devices 3 and 4 which can be used as auxiliary or signal switches.
  • the profile (in the plane of the drawing) is adapted to that of a circuit breaker with approximately half the width of the pitch and level side surfaces that are common with miniature circuit breakers: This means that the additional switch can also be retrofitted to the Customers can be easily attached to a miniature circuit breaker using simply designed connection means if the circuit breaker is prepared accordingly with transmission means to be described in more detail.
  • the two contact devices of the additional switch can be switched on by hand by means of an operating knob 5 which is pivotably mounted on an axle fixed to the housing, in that a plunger 6 articulated on the latter operates via a latching point 7 on an axially mounted intermediate lever 3a of the contact device 3.
  • a push rod 8 is movably held in a recess on the lever side opposite the latching point, which push rod is guided between housing ribs, engages with its free-standing end 8a in an edge notch of a similarly designed intermediate lever 4a and also takes the contact device 4 with it.
  • Both double-armed intermediate levers are pivotally mounted on axially fixed axles 9 and carry in extension their lower lever arms contact levers 3b and 4b, which are held in a manner not shown in each case via a tension spring 10 which is also attached to the housing.
  • the latter act as switch-off springs and, due to the nature of their suspension in connection with the contact levers, also take on the function of contact pressure springs in both switching positions with the necessary burn-up reserve.
  • the contact levers come into contact with fixed contact points 3c or 4c, the switch-off position in the exemplary embodiment likewise being marked by fixed contact points 3d or 4d.
  • the two contact levers and all four fixed contact points are each guided to terminals 11 via correspondingly arranged lines.
  • an angular trigger lever 12 which is mounted on a fixed axis, is provided, one lever arm 12 a of which is connected through an opening in the housing chamber to the switching mechanism, not shown, of the adjacent circuit breaker.
  • the other lever arm 12b acts on the latching point 7 and at the same time forms a slideway for the plunger 6 when it is switched on.
  • an approximately V-shaped pawl 14 is mounted on a fixed axis 13 in the swivel range of the intermediate lever 4a. The pawl is pivoted clockwise by means of a leg spring 15, whereby it can either come into contact with a peg-shaped extension 5a of the operating knob or with a segment-shaped lock 16.
  • the latter is stiffly mounted in the housing chamber and in the cover, for example by means of elastic interlocking of roller-shaped partial segments, and adjustable from the limit position shown in FIG. 1 to the other limit position shown in FIG. 3 via a slot 16a, which is arranged in front of the axis the attachment of the additional switch to the circuit breaker is accessible through the open bearing hole in the housing chamber 1.
  • An independent adjustment of the lock within its swivel range limited by stops is, however, impossible, since the two positions are also secured by locking lugs.
  • the outer surface of the locking device is visible in a window 1a which is recessed in the side wall of the housing chamber 1, so that markings corresponding to the limit positions can be displayed.
  • the lock 16 is shown in the right-hand stop, synonymous with the mode of operation as a signal switch for the contact device 4.
  • the switch-on position shown in FIG. 1 is obtained when the Operating knob 5, which engages via a pin 5b in a corresponding coaxially arranged toggle of the circuit breaker, has been flipped, the plunger 6 via the latching point 7 bracing the intermediate lever 3a via dead center.
  • the pivoting movement has also been transmitted via the push rod 8 to the intermediate lever 4a, and both contact levers 3b and 4b have come to rest at their fixed contact points 3c and 4c.
  • the approach 5a of the control knob has pivoted the pawl 14 in the counterclockwise direction via the lever arm 14a, so that a latching pin 4e on the intermediate lever 4a comes to lie approximately between the two lever arms of the pawl.
  • This has on its other lever arm 14b a support surface 14c which can lock the latching pin 4e.
  • the other contact device 3 working as an auxiliary switch is pivoted clockwise under the action of its tension spring 10 due to the plunger 6, which retracts with the toggle movement, until the contact lever 3b comes into contact with the other fixed contact point 3d.
  • the contact device 4 can thus, under the action of its spring 10 in synchronism with the contact means 3 pivot, 'since the Verklinkungszapfen 4e in the free space between the two lever arms of the pawl can slide before the support surface 14c disables it.
  • the contact lever 4b thus also comes into contact with its other fixed contact point 4d, so that when the circuit breaker is automatically switched off, both the auxiliary switch and the signal switch switch over, and the position of the contact device is similar to FIG. 3.
  • the lock is in the left stop, d. that is, the contact device 4 works as an auxiliary switch. Regardless of a manual or automatic switch-off of the circuit breaker, the lock 16 'always pushes the pawl 14 into a position in which the latching pin 4e cannot come into contact with the support surface 14c, as in the case of an automatic release.
  • the additional switch works on both contact devices as an auxiliary switch.
  • the "ON" position i. that is, both contact devices are switched on (FIG. 1)
  • the position "automatically OFF”, i. H. both contact devices are switched off (similar to Fig. 3) and also the position “manually operated OFF", i. H. the contact device 3 switches off, while the contact device 4 remains switched on (FIG. 2).
  • the various signals can be tapped accordingly at the connection terminals and displayed, for example, by indicator lamps.
