Definitions

  • the present invention relates to a microswitch control of a remote drive for switching devices according to the preamble of patent claim 1.
  • Remote actuators of this type are used to operate electrical switching devices such as circuit breakers remotely, in which the actuating toggle of the circuit breaker mechanically coupled to the operating knob of the remote operator and this is electromotive umlegbar.
  • This usually serves an electric motor, which is via an eccentric disc, a so-called steering wheel, with the operating linkage of the toggle, preferably by means of a connecting rod in operative engagement and thus converts the rotational movement of the electric motor in a pivoting movement of the knob.
  • This drive is preferably provided for switching a circuit breaker and has an electric motor connected to control lines. Through a gear and a cooperating power transmission mechanism (connecting rod), the drive is coupled to a control knob of the circuit breaker.
  • an output-side gear is designed as a steering wheel, on which a Einschaltzugstange is mounted on a crank pin.
  • the pull-in rod engages in an arcuate gate of a Knebelrads, which is mounted concentrically with the control knob of the adjacent self-switch in the drive housing.
  • the toggle wheel in this case has a bearing point for a Ausschaltzugstange and a control edge for actuating a lever.
  • the Ausschaltzugstange acts positively with a driving lugs having, annular recess of the steering wheel together, while the lever is mounted fixed to the housing and by means of the control edge of the Knebelrads against the moment of an acting on him force accumulator is pivotable.

  • a cam groove provided with an incision is circumferentially formed, with which a second micro-switch acting on the control lever cooperates.
  • the known remote drive uses a complicated mechanism for controlling the electric motor drive for actuating the remote drive knob.
  • Such a complicated mechanism is not only extremely difficult to assemble with the Risk of causing assembly errors in mass production, but also has control inaccuracies due to the play of the respective relatively movable mounted to each other actuators, which may eventually lead to loss of function of the remote drive with prolonged use of the remote control.
  • the object of the invention is therefore to provide a micro-switch control of a generic remote drive, which has a comparison with the prior art described above simplified structure, so that it is easier to install and has a lower susceptibility to interference.
  • the steering wheel has two cam tracks for operating two micro-switches, one of which is a switch on / off switch for actuating the electric motor and the other switch is a changeover switch between an actuation of the electric motor for a tensioning of the knob and an actuation of the Electric motor switches at least for an intentional release of the toggle.
