Definitions
- the invention relates to a remotely controllable drive device for switching on and off electrical circuit breakers 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.
- a known drive device of this type (US-A-3 893 050) has two electromagnets, each connected to the drive slide by a lever mechanism, which are alternately energized to switch 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 invention makes use, in modified form, of features which have already been used as a reversing mechanism in installation switches (remote impulse switches). These devices, like the drive device according to the invention, allow the alternate opening and closing of contacts by successive brief excitation of an electromagnet.
- known devices of this type US-A-2 046 401 and FR-A-605 918) form unitary devices together with the contacts and their power supplies
- the drive device according to the invention is a device separate from the actual circuit breaker , which is used when necessary and attached to the circuit breaker.
- the known reversing mechanisms cannot easily be used as a drive device for circuit breakers. While only comparatively low currents are to be switched in the case of remote installation switches and consequently only low actuation forces are required, the movement resistance to be overcome when actuating circuit breakers is of a different order of magnitude. Mechanical stresses thus occur which the known reversing mechanisms are not up to and which cannot be dealt with simply by increasing the dimensions. In particular, high demands are placed on the reliability of the reversing of the lever mechanism, so that it is ensured that after each switching action when the electromagnet is energized again, the opposite switching action takes place and not z. B. an idle stroke.
- the invention achieves these requirements with only a few and simply designed parts.
- Figures 1 to 5 are plan views showing the construction and operation of the drive device for a circuit breaker. 1 shows the switch-off position at the start of the switch-on process.
- Fig. 2 shows the state during the switching process immediately after switching on.
- Fig. 3 shows an intermediate position during the transition to the preparation for the switch-off after the switch-on operation is completed.
- An electromagnet 5 of the diving armature 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 pivotably mounted on a fixed shaft 11 .
- the shaft 11 is located above the electromagnet 5 in the housing in which the drive device 1 is housed.
- a driver 12 the central 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 this shaft 13 and the fixed shaft 11 is under chip tion 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 drive slide 4 by engaging in its coupling slot 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 bolts 17b and 17c of the lever 17 are alternately gripped by the hook-like ends 12a and 12b of the driver 12 and driven by the action of the electromagnet 5 so that the lever 17 is pivoted clockwise or counterclockwise in order to move the drive slide 4 upwards or downwards slide 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 drive slide 4 is moved downward and the armature 8 is in its rest position under the action of the return spring 14.
- the coupling pin 17a assumes its lower position while the driver 12 together with the armature 8 has moved upwards and remains there, while the hook-like end 12b engages the coupling pin 17c of the lever 17. If 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 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 coupling pin 17a drives the drive lever 4 down until the operating handle 2 of the circuit breaker, not shown, is pressed to its lower switch-off position, as shown in FIG. 5. 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 dead 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, whereby the position of the parts shown in FIG. 1 is restored.
- a driver is provided in the drive device according to the invention, the hook-like ends of which, when the armature of an electromagnet is reset, interacting alternately with two coupling bolts of a two-armed lever, so that a circuit breaker is switched on and off using a single electromagnet can. Therefore, the drive device can be manufactured inexpensively with a simple structure and small size.
