Abstract

A remote-controlled mechanism according to an embodiment is used for coupling to a protective switching device to use a controllable drive device of the remote-controlled mechanism to actuate the coupled protective switching device. To this end, the remote-controlled mechanism includes: an actuating element operatively connectable to an actuating element of the coupled protective switching device and actuatable either by a remotely controllable drive device of the remote-controlled mechanism or manually; one or more sensor devices for capturing position data relating to a position of the actuating element of the remote-controlled mechanism; and a controller for evaluating the captured position data and for controlling the drive device via control commands. The controller is designed to disable the drive device upon an evaluation of the position data and/or of the control commands revealing that the actuating element of the remote-controlled mechanism has been switched off manually.

First claim

What is claimed is:

1. A remote-controlled mechanism configured to be coupled to a protective switching device to use the remote-controlled mechanism to actuate the coupled protective switching device, the remote-controlled mechanism comprising:
an actuating element, operatively connectable to an actuating element of the coupled protective switching device, manually actuatable or actuatable by a remotely controllable drive device of the remote-controlled mechanism;
one or more first sensor devices configured to capture position data relating to a position of the actuating element of the remote-controlled mechanism;
a controller configured to evaluate the position data captured and to control the remotely controllable drive device via control commands;
a driving shaft configured to mechanically transmit a tripping movement; and
a second sensor device configured to sense a movement of the driving shaft,
wherein the controller is configured to disable the remotely controllable drive device upon an evaluation of at least one of the position data or the control commands revealing that the actuating element of the remote-controlled mechanism has been manually switched off.

2. The remote-controlled mechanism of claim 1 , wherein the controller is configured to cancel a disablement of the remotely controllable drive device for a period of time after the controller has received a signal from a higher-level unit of the remote-controlled mechanism.

3. The remote-controlled mechanism of claim 2 , wherein the first sensor device is configured to sense a movement of the remotely controllable drive device.

4. The remote-controlled mechanism of claim 1 , wherein the first sensor device is configured to sense a movement of the remotely controllable drive device.

5. The remote-controlled mechanism of claim 1 , further comprising:
a voltage sensor configured to measure a level of a supply voltage of the remote-controlled mechanism.

6. An equipment arrangement, comprising:
the remote-controlled mechanism of claim 1 ; and
the protective switching device coupled to the remote-controlled mechanism.

7. An equipment arrangement of comprising:
a protective switching device;
a remote-controlled mechanism configured to be coupled to the protective switching device to use the remote-controlled mechanism to actuate the coupled protective switching device, the remote-controlled mechanism including
an actuating element, operatively connectable to an actuating element of the coupled protective switching device, manually actuatable or actuatable by a remotely controllable drive device of the remote-controlled mechanism,
one or more sensor devices configured to capture position data relating to a position of the actuating element of the remote-controlled mechanism,
a controller configured to evaluate the position data captured and to control the remotely controllable drive device via control commands, and
a driving shaft; and

a supplementary device coupled to the remote-controlled mechanism,
wherein the controller is configured to disable the remotely controllable drive device upon an evaluation of at least one of the position data or the control commands revealing that the actuating element of the remote-controlled mechanism has been manually switched off, and
wherein the driving shaft is configured to transmit a tripping movement initiated by the supplementary device to the protective switching device, mechanically.

8. A method for switching on a protective switching device coupled to a remote-controlled mechanism, the remote-controlled mechanism including an actuating element operatively connected to an actuating element of the protective switching device, the actuating element of the protective switching device being actuatable to switch on the protective switching device and being manually actuatable or actuatable by a remotely controllable drive device of the remote-controlled mechanism, the method comprising:
disabling the remotely controllable drive device upon an evaluation of at least one of position data describing a position of the actuating element of the remote-controlled mechanism, or control commands relating to operation of the remotely controllable drive device revealing that the actuating element of the remote-controlled mechanism has been manually switched off;
mechanically transmitting, via a driving shaft, a tripping movement; and
sensing, via a sensor device, a movement of the driving shaft.

9. The method of claim 8 , wherein the disabling the remotely controllable drive device is cancelled for a period of time after the remote-controlled mechanism has received a signal from a higher-level unit of the remote-controlled mechanism.

10. The method of claim 9 , further comprising:
disabling the remotely controllable drive device after a reset has been performed for the remote-controlled mechanism that puts the remote-controlled mechanism into a defined initial state.

11. The method of claim 9 , further comprising:
disabling the drive device upon the remote-controlled mechanism being put into operation by applying a supply voltage.

12. A non-transitory computer program product storing software code sections, directly loadable into an internal memory of a digital computer, to carry out the method of claim 9 when the software code sections run on the computer.

13. The method of claim 8 , further comprising:
disabling the remotely controllable drive device after a reset has been performed for the remote-controlled mechanism that puts the remote-controlled mechanism into an initial state.

14. A non-transitory computer program product storing software code sections, directly loadable into an internal memory of a digital computer, to carry out the method of claim 13 when the software code sections run on the computer.

15. The method of claim 8 , further comprising:
disabling the drive device upon the remote-controlled mechanism being put into operation by applying a supply voltage.

16. A non-transitory computer program product storing software code sections, directly loadable into an internal memory of a digital computer, to carry out the method of claim 15 when the software code sections run on the computer.

17. A non-transitory computer program product storing software code sections, directly loadable into an internal memory of a digital computer, to carry out the method of claim 8 when the software code sections run on the computer.
