Definitions

  • the invention relates to a switching device, consisting of a switching drive and a power switching device, wherein an auxiliary switching device that can be retrofitted to the housing exterior is provided on the power switching device, preferably with two auxiliary contact pairs, which are designed as normally closed and normally open contacts and which each have a movable contact bridge depending on the intended function are connected to a closed current path.
  • the overload is triggered by the thermal relay, which interrupts the self-holding of the contactor coil by means of an NC contact and thus switches off the contactor.
  • a second normally open contact can signal the thermal.
  • Short-circuit currents are switched off via the power switching device, which thus also takes over the protective function.
  • a motor starter combination which has a power switching device with short-circuit and overload release and a switching drive in the form of a contactor coil.
  • the overload release acts directly on the switching drive. It is a compact device with a rigid functional sequence. Additional auxiliary switches must be provided for signaling the switching states.
  • the overload release only affects the switch drive and is not intended to trigger the switch lock.
  • the invention is therefore based on the object of converting a commercially available power switching device, such as that which can be used as a motor protection switch, with simple means and without an expensive change to a motor starter which can be switched on again after an overload release by remote switching or by switching "on site".
  • the effect of the overload release which is preferably designed as a thermal release, is passed on to the auxiliary switch by the mechanical transmission means and causes the latter to switch over or signal.
  • the chain of action between the thermal release and the switch lock is interrupted - for example by removing an intermediate lever - so that the other functions of the power switching device, such as the switch lock and contact system, are not affected by the overload circuit.
  • Switching of the auxiliary switching device can advantageously be achieved by a simple switching lever which is rotatably mounted in the auxiliary switching device and projects into the power switching device in such a way that it is actuated by the release lever of the overload release and causes the switching of the auxiliary switching device.
  • the auxiliary switching device can be designed so that the switching lever acts on a toggle spring mechanism and switches this from a stable position to a second stable position.
  • the switch back can be carried out via a pushbutton element which allows the reset manually. If the pushbutton element is locked in the pressed position, there is no changeover via the tipping point and the automatic reset of the auxiliary switching device after each switching.
  • the switching device can be switched on again by applying the coil current via a pushbutton element which is connected to the switching drive and can be arranged at a distance from the switching device.
  • the interaction according to the invention of the connection between the power switching device 1 and the auxiliary switching device 2 is shown in Fig. 2.
  • the arm 22 projects through the opening 13 in the housing wall 12.
  • the switch lever 21 is rotatable in the auxiliary switching device 2 by means of an axis about the pivot point 24 stored.
  • This fulcrum 24 can be moved by a small range in the direction of movement of the trigger lever 10.
  • the point of contact of the arm 22 on the release lever 10 can be adjusted.
  • the fulcrum 24 will be fixed by known means such as sealing, gluing or screwing.
  • the further arm 23 of the switch lever 21 transmits the movement of the release lever 10 of the overload release 110 to a tilting element 25.
  • the mode of action of the arm 23 on the tilting element 25 can be seen in the illustration in FIG. 3.
  • the tilting element 25 consists of a tension spring which is suspended on the one hand in an abutment 28 and on the other hand on a contact carrier 26 which carries the movable contact bridges 93 and 94 and an insulating piece 92 arranged between them.
  • the insulating piece 92 is used only for the electrical isolation between the contact pairs 95/96 and 97/98.
  • the contact carrier 26 is seated in a cutting edge bearing, which forms the dead center for the pendulum movement.
  • the contact bridges 93 and 94 oscillate suddenly due to the actuation by the arm 23 via a tipping point between two stable switching positions on the fixed contacts 95/96 and 97/98.
  • the resetting against the movement of the arm 23 is carried out by means of the reset button labeled 30 in FIG. 2.
  • the fixed contacts 97/98 are arranged displaceably and can be displaced in the direction of the arrow to such an extent that the contact carrier 26 no longer swings over the dead center, but falls back to the contacts 95/96. This shift is carried out by the reset button 30 by being pressed in and locked in a bayonet-like manner.
  • the reset button 30 can be seen, which acts on the contacts 97/98 via an intermediate lever 31, which is under the action of a spring 32.
  • the contacts are 97/98 with the reset button 30 pressed so far in the direction of the contact bridge 94 that the tilting element 25 does not exceed the tipping point, but instead connects the break contacts 95/96 again when the switch lever is moved into the starting position by means of the contact bridge 93.
  • the switching device can thus be brought back into the switched-on position by means of a button 5, as shown in FIG. 1.
