Definitions

  • the invention relates to a power drive for electrical switching devices, in particular low-voltage circuit breakers, with a support plate for drive parts and with a drive slider spanning an actuator of the switching device with a window-like opening.
  • a power drive of this type is e.g. B. known from US-PS 33 28 731.
  • the drive slide is guided on the support plate.
  • the correct alignment of the slide or its window-like opening with respect to the actuating member is based on. the correct connection of the support plate with the - switching device.
  • Inevitable tolerances can, however, result in the drive slide not interacting with the actuating element in a flat or linear manner and consequently the driving forces in the actuating element are not uniformly introduced, but instead are concentrated locally in an undesirable manner. This can result in premature wear of the interacting parts or even breakage of the actuator.
  • the invention has for its object to ensure a low-wear interaction of the drive slide with the actuator of the switching device regardless of the attachment of the support plate to the switching device.
  • this object is achieved in that the drive slide is arranged between the support plate and the side of the switching device having the actuating member and is guided on these parts.
  • lateral guidance can also be achieved in that the drive slide has side walls for guiding an elevation surrounding the actuating element on the front side of the switching device.
  • Such surveys are usually present on the switching devices of the type generally referred to as compact switches. The distance between the side walls of the drive slide is then adapted to the width of this elevation.
  • the design of the drive slide described offers the possibility, when attaching a power drive to a switching device of the type mentioned, to first place the drive slide on the front of the switching device such that the actuating member passes through the window-like opening and then the support plate with the other drive parts put on the switchgear.
  • the support plate with the drive parts including the Attach drive slide to the switching device it may be advantageous to provide the drive slide with an elongated hole extending in its direction of movement for the passage of at least one holding member attached to the support plate.
  • This holding element only has the task of avoiding loosening of the drive slide from the support plate.
  • the holding member is not intended to guide the drive slide after it has been attached to the switching device, which can be achieved by a corresponding tolerance between the elongated hole and the holding member.
  • the mounting of the drive slide on the support plate until it is mounted on the switching device can be further improved in that the drive slide additionally has on its side opposite the elongated hole a web which is gripped by an arm of a control slide guided on the support plate parallel to the direction of movement of the drive slide becomes.
  • the web and the arm There should also be a relatively large amount of play between the web and the arm, so that the orientation of the drive slide relative to the drive element of the switching device is in no way influenced by this holder.
  • the control slide mentioned serves to switch off a motor of the power drive when the desired switching positions of the switching device are reached.
  • it can be designed as a drag valve and can interact with the webs which also serve to secure the position of the drive valve.
  • the desired precise ab circuit of the motor can be achieved in that the control slide has a control cam for a limit switch designed as a snap switch.
  • the control spool can carry markings for the switch-on position and the switch-off position.
  • FIG. 1 shows a top view of a power drive according to the invention, while a side view is shown in FIG. 2.
  • FIG. 3 A detail of a control slide is shown in FIG. 3.
  • the power drive designated as a whole by 1, is assigned to a low-voltage circuit breaker 2 of the compact type, the outline of which is partially shown in broken lines in FIG. 2.
  • An actuating handle 4 with which the circuit breaker 2 can normally be switched on and off by hand, protrudes from a central elevation 3 of the circuit breaker 2.
  • a drive slide 5 interacts with this actuating handle and is provided with a window-like opening 6 for this purpose.
  • This is designed such that two curved surfaces 7 substantially corresponding to the width of the actuating handle 4 and then extensions 10 are provided on both sides. These extensions ensure that there are no corners or edges that could locally increase the stress on the material of the actuating handle 4.
  • the distance between the surfaces 7 is selected such that even in the end positions of the actuating handle 4 (an intermediate position resulting when the protective switch 2 is switched on or off is shown in FIG. 2) there is little play and jamming is avoided.
  • the control slide 22 is also longitudinally displaceable in the direction of the double arrow 16 in a slot in the support plate 13 and engages behind the arms 20 of the drive slide 5 with arms 25.
  • a resilient extension 18 (FIG. 3) of the control slide 22 pulls it against its support surface on the support plate 13 and thereby causes a friction inhibition to prevent self-movement without drive.
  • the arms 25 complement the holder of the drive slide 5 by the mentioned holding member 17.
  • the drive slide is consequently held on the support plate 13 with considerable play such that it cannot come loose and can therefore be placed on the circuit breaker 1 together with the other parts of the power drive .
  • the guide passes from the holding member 17 and the extensions 25 to the actuating handle 4 and the curved surfaces 7 or the support plate 13 and the top of the circuit breaker 2.
  • the control slide / has a display surface 40 which extends to just below a cap 41 which covers the motor drive 1 to the outside and which is provided with markings for identifying the switching position.
  • the control slide thus fulfills several functions in that it not only controls the switching on and off of the motor 26, but also forms a holder for the drive slide 5 and indicates the switching position.
  • the power drive 1 further comprises a motor 26 in connection with a gear 27, which comprises an output shaft 28 which is perpendicular to the support plate 13 and has a crank arm 29 and a crank pin 30.
  • the crank pin 30 engages between the legs 31 of a U-shaped leaf spring 32 which extends transversely to the direction of movement of the drive slide 5 and on the drive slide on the one hand in an opening 33 and others is supported on the one hand in an opening 34.
  • the opening 34 merges into a pocket-like recess 35, in which the one leg 31 of the leaf spring 32 is latched with a bent end 36.
  • a screw 37 extends between the legs 31 in the region of the opening 34 and supports the legs against one another.
  • the protective switch 2 can be switched on and off alternately by rotating the crank arm 29 in the same direction by about 180 ° in each case.
  • the drive slide with the actuating handle 4 is in a central position corresponding to a rotation of the crank arm 29 by approximately 90 ° with respect to its end positions.
