Abstract

Device for controlling an electric disconnecting switch motor, including a power supply circuit for supplying power to motor from a network voltage source, said circuit including a static converter controlled to output a voltage having a predetermined value to motor; and one or more configuration components, the actuation of which enables the configuration of said circuit with a view to setting the direction of the current (i) that flows in motor, characterised in that control of static converter and control of configuration components are provided by two separate control units, each outputting control instructions, the control instructions of one of the two control units being activated on the basis of a validation instruction from the other control unit.

Claims

1. Device for controlling a motor of an electric disconnecting switch, comprising a power supply circuit for supplying power to motor, from network voltage source, said circuit including a static converter controlled to output a voltage having a predetermined value to motor through instruction orders output by a main control unit an additional control unit with which main control unit communicates, the control instructions orders of main control unit being activated on the basis of a validation instruction from additional control unit.

2. Device as claimed in claim 1, wherein the main control unit and the additional control unit comprises a microcontroller.

3. Device as claimed in claim 1, wherein the static converter is controlled by pulse width modulation instructions.

4. Device as claimed in claim 3, wherein the pulse width modulation instructions are output to static switch, the control circuit of which has one terminal that is connected to control unit that outputs pulse width modulation instructions and another terminal that is connected to additional control unit.

5. Device as claimed in claim 1, wherein additional control unit is only powered during phases when the validation instruction is output.

6. Device as claimed in claim 1, wherein the two control units each have their own clock.

7. Device as claimed in claim 1, wherein the two control units communicate in order to receive and confirm the validation instruction.

8. Device as claimed in claim 1, wherein communication between the two control units is encrypted.

9. Device as claimed in claim 1, further comprising one or more configuration components, the actuation of which enables the configuration of the power supply circuit for supplying power to the motor with a view to setting the direction of the current (i) that flows in motor and wherein the instructions intended for configuration components are provided by the control unit that provides the control instructions for static converter.
