Definitions

  • the invention relates to an actuator for on and Switching off power switching devices, especially for multi-phase Motor protection switch.
  • Such an actuating device is known from DE 43 04 769 C1 known, which consists of a rotary knob and a key switch exists that by means of a toggle lever and a transmission part on the movable and with two fixed contacts per phase in and out of contact contact bridges acts, whereby the toggle lever through the chain of effects of rotary knobs, one Actuating shaft and a shift gate in the switch-on position is moved, in which a support lever on a jack rocker supports and gives the toggle lever a stable position, however, with manual shutdown or with fault triggering by thermal or electromagnetic trigger suddenly breaks down and a quick shutdown of the power switching device causes.
  • DE 30 03 328 C2 is another actuating device known for a motor protection switch by a the connecting terminals and the switching contacts Lower housing part and an actuator and Trigger means receiving upper housing part.
  • the actuator consists of a switch lock, the switching gate of one push button each to open and close the switch contacts must be actuated.
  • the pushbuttons are in the Upper housing part stored and sufficient with control surfaces Outside. The disadvantage of these known actuators is that it can only be done either by turning a knob or can only be operated by push buttons.
  • DE 41 37 890 A1 is a Actuator known, snap-action arrangements depending on your choice, using a rotary knob or push buttons is pressed. Neither the rotary knob nor the push buttons decrease the release of the switching state of the snap-action switching arrangements according to the position prescribed for power switching devices is.
  • DE 21 35 977 A1 a switching element either with a rotary knob or a push button against one Return spring are moved, being used for the transfer of the Rotary or pushing movement on the switching element different Pins and different for maintaining the switch position Locking agents are used.
  • This actuator can on an actuator for a Usual key switch with rotating or tilting parts be taken over.
  • the invention has for its object an actuator of the type mentioned at the beginning, of your choice to be operated by a rotary knob or by push buttons.
  • the push buttons are more advantageous Way captive in the second pre-assembled upper housing part stored.
  • the second upper part of the housing should be used a greater overall height than the first upper housing part have so that the actuating shaft is inaccessible from the outside is and around guide surfaces for the stored push buttons too form.
  • the captive storage is also useful the return springs in the pre-assembled second housing upper part.
  • the power switching device 1 contains for example a multi-phase motor protection switch, one of a first actuator 21 or a second Actuating means 22 to be actuated switch lock 3.
  • the Switch lock 3 consists in a known manner of an actuating shaft 31, one with this operatively connected and pivoted Gear shift 32, a support lever, one on movable Contact bridge acting toggle and a lock bracket 33 for holding the switch lock 3 in a lower housing part 4 of the power switching device 1.
  • Way supports in the on position of the support lever against a jack rocker and the key switch 3 breaks when switched off manually or in the event of a fault being triggered by a thermal release 5 or electromagnetic trigger by releasing the Quick release latch rocker from the support lever.
  • first upper housing part 61 or a second upper housing part 62 is to be connected to the lower housing part 4 and covers that Switch lock 3, the trigger 5 and the input and output side Terminal rooms 7 from.
  • the first designed as a rotary knob Actuating means 21 sits in front of the first upper housing part 61 and is to be connected to the actuating shaft 31, which in turn acts on the shift gate 32.
  • the second actuator 22 is mounted in the second housing upper part 62 and as a push button for manual switching 221 and as a push button trained for manual shutdown 222.
  • the push buttons 221 and 222 are directly bypassing the actuating shaft 31 with the switching link 32 in operative connection, with regard to the axis of rotation 321 of the shift gate 32 opposite Act.
  • the first actuator 21 and the second actuator 22 can be used optionally.
  • the first housing top 61 has an opening 611 for connecting the first actuating means 21 with the actuating shaft 31 Mistake.
  • the second upper housing part 62 has openings 621 and 622 to accommodate push buttons 221 and 222 Mistake.
  • the second upper housing part 62 faces the first upper housing part 61 has a height that essentially by the length of the actuating shaft protruding from the switch lock 3 31 and mainly around the height of guide surfaces 2211 or 2221 of the push buttons 221 and 222 is larger.
  • first Setting means 51 and a second setting means 52 are provided, the different axis lengths to adapt to the different heights of the first upper housing part 61 or of the second upper housing part 62. That points to second setting means 52 an additional intermediate shaft 521 on.
  • the setting means 51 and 52 are each one further opening 613 of the first housing upper part 61 or another opening 623 of the second housing upper part 62 accessible from the outside.
  • the pushbuttons 221 and 222 are in constant contact with the switching link 32.
  • the return springs designed as tension springs 2212 and 2222 are on the one hand in a respective Blind bore 2213 or 2223 of the associated push button 221 or 222 guided and fixed at the end and on the other hand in second upper housing part 62 set. With that take the push buttons 221 and 222 in every position of use of the power switchgear 1 a position defined with respect to the shifting gate 32 on.
  • the return springs can be arranged accordingly also be designed as compression or leaf springs.
  • the lock bracket 33 is with a first recess 331, through which the actuating shaft 31 extends.
  • 3 to 5 is the lock holder 33 with a second recess 332 through which the push button for manual activation 221 with an engagement plunger 2214 enough, as well as with a third recess 333 through which the push button for manual shutdown 222 with an engagement plunger 2224 is enough, provided.
  • the switch lock 3 is therefore without the implementation of other measures depending on your choice for both Operate via the first actuating means 21 as well as for the Operate via the second actuating means 22 suitable.
  • the push button for manual activation 221 an opening 2215 for closing the power switching device 1 when switched off by means of a hook U-lock on.
  • pressing the push button to Manual switch off 222 becomes the push button for manual switch on 221 by means of the counteraction via the switching link 32 the force of their return spring 2212 from the second Upper housing part 62 pushed out and thereby gives the opening 2215 free.
  • the shift gate 32 is formed with a Lock cam 322 provided in the switch-on position of the shift gate 32 in a molded locking link 2216 of the push button for manual engagement 221 engages positively.
