Definitions

  • the invention relates to a motor protection switch according to the first part of claim 1.
  • the invention has for its object to provide an economically producible, reliable motor protection switch, in which it is perfectly recognizable from the outside, in which operating state it is and whether an overcurrent or a short circuit has occurred.
  • a restart operation in both triggering cases should be able to be carried out safely in the same simple manner.
  • a rocker bar that is operatively connected to the linkage is provided, which is connected to a spring, which strives to hold the rocker in its middle trip position.
  • the spring is tensioned when you switch on or off, whereby the rocker is swiveled towards one side or the other like a balance beam.
  • the spring can return the rocker to the trip position, and the actuator can also be moved to the trip position. You can also let other parts of the boom move from the seesaw to a trip position.
  • the rocker can be used in this way to bring about the trip position of the actuating member.
  • knee joint brackets are preferably used, the two brackets of which are connected by a knee joint in such a way that a kinked position of the knee joint brackets is latched on both sides of a stretched position.
  • the one kink position is the off position and the other kink position is the on position.
  • the on and off position can be reached by moving the knee joint accordingly.
  • the free end of the one link is preferably connected by an end joint to a contact actuating lever which can be pivoted about a frame bearing, while the free end of the other link is connected by an end joint to a latch lever which can be pivoted about a frame bearing.
  • Both of the mentioned end joints are arranged in such a way that a straight line connecting them lies in every position of the linkage between the on and the off position of the knee joint.
  • the knee joint is preferably guided in a guide running transversely to its switching movement direction and is drive-connected to a linkage part articulated on the rocker.
  • the knee joint can take account of the various switching states from its on position along the guide, while evading laterally. So the knee joint can release and release the ratchet lever including the linkage and rocker are moved from the rocker spring to the trip position, while the contact operating lever swings into its off position and can separate the contacts.
  • the outer display is also visible, which does not fundamentally change the restart process, but clearly warns of it.
  • This outer display is advantageously operatively connected to a bistable tilting device, only the short-circuit release being able to transfer the tilting device from its rest position into the display position.
  • This return is preferably carried out when the actuator is moved from the trip to the off position. This means that readiness for switch-on is created, as previously described.
  • the actuating member or a linkage part can be designed such that an active connection can only take place during the aforementioned return process of the tilting device in the display position. This is easily possible. A preferred solution can be seen in the drawing.
  • the frame of the motor protection switch is represented by triangles hatched on one side as support points and by parallel lines hatched on both sides as sliding guides of the frame. - Circles indicate joints.
  • the motor protection switch shown has a fixed contact pair 1 which can be connected to supply lines and a contact pair 2 which is movable relative thereto.
  • a pair of switching buttons with an on button 3 and an off button 4 is provided as an externally visible actuating member, which act on a linkage 5.
  • the rocker 10 which can be operated by means of the control buttons is mounted on the frame at point 100 and is urged into its central position (corresponding to its trip position in FIGS. 3 and 4) by its rocker spring 11.
  • This rocker 10 is in operative connection with the knee joint 15 of the knee joint brackets 12 via the plunger 23 and the sliding guide 22 attached to it.
  • the tab 13 of the knee joint tabs 12 is connected to the angular contact actuation lever 18 via the end joint 16.
  • the contact actuating lever 18 is pivotally mounted on the frame bearing 17 and is pulled by the spring 180 against the stop 181 into the disconnected position of the contacts (FIGS. 1, 3 and 4).
  • the tab 14 of the knee joint tab 12 is connected to the pawl lever 21 via the joint 19.
  • This pawl lever 21 is pivotally mounted on the frame about the bearing 20 and is held in the latched position (FIGS. 1 and 2) by the pawl 6 against the spring 210 on or close to the stop 211.
  • a bimetallic element is indicated as the overcurrent release 7, which can actuate the pawl 6 via a plunger 70 without the release linkage 81 of the short-circuit release 8 being moved thereby.
  • the short-circuit release 8 is an electromagnetic device indicated by the relay symbol, the armature of which actuates the linkage 80, 81 when a short-circuit current flows.
  • the trigger linkage 81 can trigger the pawl 6 without moving the plunger 70 of the overcurrent release 7.
  • the display linkage 80 of the short-circuit release 8 is shown here as a plunger which lies loosely (only for pushing, not for pulling) on the outer display 9.
  • the outer display 9 is operatively connected to the rocker arm 240 of the bistable tilting device 24, which is held by the rocker spring 241 in the rest position (FIGS. 1 to 3) or display position (FIG. 4).
  • the rocker arm 240 can be returned by the return member 30 of the linkage 5 from the display position (FIG. 4) to the rest position (FIG. 1) when the trip position is switched to the off position.
  • the motor protection switch can be switched on by pressing the on button 3 from the off position (FIG. 1) to the on position (FIG. 2), its linkage 5 from the off position shown in FIG. 1 to the position shown in FIG 2 On position shown passes over.
  • the rocker 10 is tilted clockwise and the knee joint lashers 12 are moved from their out-of-bend position to the in-bend position in the extended position, not shown, in which they remain.
  • only the contact operating lever 18 is velvet Contact pair 2 moves because the knee joint plates 12 are articulated with the knee joint 15 in the sliding guide 22 and with the end joint 19 on the pawl lever 21 held immovably (between the stop 211 and the pawl 6).
  • Overcurrent release (FIG. 3): An overcurrent heats the overcurrent release 7, which releases the pawl 6 against the spring 60 via its plunger 70. After the overcurrent release 7 has cooled (its circuit is interrupted when it is released), the pawl 6 returns to the rest position pulled by the spring 60. The trip position of the switch buttons (without the outer display 9) indicates overcurrent tripping. As a result, the detached pawl lever 21 can move from the spring 210 from the latching position shown in FIG. 2 to the release position shown in FIG. 3. As a result, the end joint 19 is moved to the right and the spring 11 can pull the rocker 10 into the trip position via the tappet 23. The knee joint brackets 12 are no longer supported by the end joint 19. The spring 180 can pull the contact actuation lever 18 together with the contact pair 2 into the off position. The contact operating lever 18 is now missing the support on the end joint 16.
  • Short-circuit release (FIG. 4): If a short-circuit occurs, the short-circuit release 8 is activated, which causes a movement of the release linkage 81 and the release of the pawl 6. The process described above follows. However, the responsive short-circuit release 8 has also actuated the display linkage 80, which has pushed out the outer display 9 and thereby tilted the tilting device 24 over its dead center position. Although immediately after the triggering of the short-circuit release 8 (its circuit is interrupted when triggered) returns to the rest position, the display position of the outer display 9 and the tilting device 24 remains.
  • the trip position of the actuator both buttons 3 and 4 are at the same height
  • the outer display indicate that the short circuit has been triggered. You can immediately see that it is not allowed to switch on again without removing the short circuit.
  • the switch-on standby position corresponds to the off position in FIG. 1.
