Definitions

  • the invention relates to a remotely controllable drive device for switching electrical protection switches on and off with an electromagnet and a drive slide for the actuating handle of the circuit breaker which can be moved by the armature of the electromagnet via a lever mechanism.
  • the known drive device of this type (JS-PS 3 839 050) has two electromagnets, each connected to the drive slide by a lever mechanism, which are alternately energized for switching the circuit breaker on and off.
  • the invention is based on the object to provide a drive device for the same application, which works with reduced dimensions, reduced weight and lower costs with only one electromagnet.
  • the lever mechanism comprises control elements which, in the case of successive strokes of the armature of the electromagnet, cause an alternating activation and deactivation of the circuit breaker on the drive slide. It is therefore sufficient to excite the existing single electromagnet and to switch it off again in order to carry out a switching operation of the circuit breaker.
  • the drive device performs the opposite switching operation from, d. H; for example, a switch-on if a switch-off took place previously
  • the driver for automatically changing the engagement with the one coupling part of the two-armed lever to the other coupling part has such a broadened middle part for guiding on the coupling parts of the two-armed lever that the driver moves over to its rest position when the armature is reset the dead center is performed.
  • the driver is shifted from one position to the other by the coupling parts provided for the power transmission in connection with a special contour of the driver.
  • the driver can have two hook-like ends open on opposite sides at its free end, and the two-armed lever can carry bolts which act as coupling parts and interact with the hook-like ends. These coupling bolts also take over the jack. the driver from one position to the other.
  • An electromagnet 5 of the submersible type comprises a magnet coil 6, a fixed core 7, a movable armature 8 and a yoke 9.
  • the magnet coil 6 carries a fastening pin 10 as an abutment of an over-center spring 16.
  • a two-armed lever 17 is pivotally mounted. The shaft 11 is located above the electromagnet 5 in the housing in which the drive device 1 is housed.
  • a driver 12 the middle part 12c of which is widened or widened and which has hook-like ends 12a and 12b on both sides, is pivotably mounted on the upper end part of the armature 8 by means of a shaft 13, between which shaft 13 and the fixed shaft 11 is underneath Tension a return spring 14 attached such that it constantly pulls the armature 8 up to its rest position.
  • the driver 12 carries in its upper part a pin 15 as an abutment of the over-center spring.
  • the drivers 12 and the two-armed lever 17 are attached as control elements between the drive slide 4 and the armature 8.
  • a first coupling pin 17a transmits the pivoting movements of the two-armed lever 17 to the A ntriebsschieber 4 by engaging in the coupling slit 4a.
  • Another coupling bolt 17b is located between the first coupling bolt 17a and the fixed shaft 11, that is to the left of this, while a third coupling bolt 17c is attached to the two-armed lever 17 to the right of the shaft 11.
  • the three coupling bolts 17a, 17b and 17c are arranged in a line.
  • the coupling pins 17b and 17c of the lever 17 are alternately detected, and by the hook-like ends 12a and 12b of the driver 12 is driven by the action of the electromagnet 5, the lever 17 is pivoted clockwise or counterclockwise, around the A ntriebsschieber 4 upward or downward to push and thereby switch the circuit breaker, not shown, on or off.
  • Fig. 1 shows the state of the parts when the circuit breaker is turned off.
  • the An drive screwdriver 4 moved to uncen and the armature 8 is under the action of the return spring 14 in its rest position.
  • the coupling pin 17a assumes its lower position while the driver 12, together with the armature 8, moves upwards and remains there, while the hook-like end 12b engages the coupling pin 17c of the lever 17.
  • the solenoid 6 is now energized, the armature 8 is attracted by the fixed core 7 against the force of the return spring 14. Then the hook-like end 12b of the driver 12 pulls the coupling bolt 17c according to FIG. 2 and thus the right end of the lever 17th down.
  • the driver 12 is caused to pivot in the direction of the coupling pin 17b when the axis of the over-center spring 16 crosses the axis of the return spring 14. Then the hook-like end 12a engages with the coupling pin 17b, as shown in FIG. 4.
  • the lever 17 is then pivoted counterclockwise by means of the coupling bolt 17b through the hook-like end 12a of the driver 12 when the magnetic coil 6 is excited again. Therefore, the clutch pin 17a drives the drive lever 4 downwards, is pushed up to the operating handle 2 of the circuit breaker, not shown, to its lower open position, as the F i g. 5 shows. If the excitation of the magnetic coil 6 is interrupted, the driver 12 returns upward, while its middle part 12a is guided along the coupling bolt 17b by the biasing force of the return spring 14. When the axis of the over-center spring 16 comes to a position on the right side of the return spring 14, the driver 12 is pivoted back to the side of the coupling pin 17c, thereby restoring the position of the parts shown in FIG. 1.
  • the drive device provides a driver which, with its hook-like ends, alternately cooperates with two coupling bolts of a two-armed lever when the armature of an electromagnet is reset, so that a circuit breaker is switched on and off using a single electromagnet can be. Therefore, the drive device can be manufactured inexpensively with a simple structure and small size.
