Abstract

A portable control device designed to control contacts of an electrical switch, and including a main drive shaft, a holding shaft, a motor for driving the main shaft and a microcontroller for controlling the motor. In a first direction of insertion, the main shaft is able to be inserted into a first recess of the switch in order to perform a movement for opening/closing the contacts, the holding shaft then being housed in a first holding orifice. In a second direction of insertion, the main shaft is able to be inserted into a second recess of the switch in order to be able to perform a movement for grounding the contacts, the holding shaft then being housed in a second holding orifice. The control device also includes a detector of the direction of insertion, which detector is linked to the microcontroller.

First claim

The invention claimed is:

1. A portable control device designed to control contacts of an electrical switch, the control device comprising a main drive shaft, a holding shaft, a motor for driving the main shaft and a microcontroller for controlling the motor, wherein the control device is designed such that:
in a first direction of insertion, the main shaft is able to be inserted into a first manoeuvring recess of the switch in order to perform a movement for opening/closing the contacts of the switch, the holding shaft then being housed in a first holding orifice,
in a second direction of insertion, the main shaft is able to be inserted into a second manoeuvring recess of the switch in order to be able to perform a movement for grounding the contacts of the switch, the holding shaft then being housed in a second holding orifice,
wherein the control device includes a detector of the direction of insertion of the control device into the switch, the detector of the direction of insertion being linked to the microcontroller.

2. The control device according to claim 1 , wherein the first holding orifice and the second holding orifice are combined into a single shared orifice.

3. The control device according to claim 1 , wherein the first holding orifice corresponds to the second manoeuvring recess and the second holding orifice corresponds to the first manoeuvring recess.

4. The control device according to claim 1 , wherein the detector of the direction of insertion includes an inertial measurement unit.

5. The control device according to claim 1 , further comprising a position detector for verifying that the main shaft has been inserted into one of the first and second manoeuvring recesses of the switch.

6. The control device according to claim 1 , further comprising an angular position sensor for determining the angular position of the main shaft.

7. The control device according to claim 1 , further comprising a detector for detecting an overload of the electric current flowing through the motor.

8. The control device according to claim 1 , further comprising a supply undervoltage detector, linked to the microcontroller, so as to prohibit movement of the motor if the supply voltage is below a predetermined threshold.

9. The control device according to claim 1 , wherein the main shaft and the holding shaft are not strictly parallel with one another.

10. The control device according to claim 1 , further comprising an actuating finger that is offset with respect to a main axis and mechanically linked to the main axis.

11. The control device according to claim 1 , further comprising a telescopic extension on which the holding shaft is mounted.

12. A system for controlling contacts of an electrical switch, the system comprising a control device according to claim 1 , and comprising a portable external console linked to the control device through a wireless link, the external console including means for identifying the switch.

13. The control system according to claim 12 , wherein the identification means include a QR code reader.
