Abstract

A system comprising a meter and a circuit breaker, the electricity meter comprising: a primary processing component designed to acquire a primary power supply parameter and to produce, from the primary power supply parameter, a primary command intended to control the opening or closure of a line; a primary transceiver designed to transmit the primary command; the circuit breaker comprising: a disconnection unit; a bistable relay designed to open or close the disconnection unit; a secondary receiver designed to receive the primary command; a secondary processing component designed to acquire the primary command and to control the bistable relay so as to open or close the disconnection unit on the basis of the primary command.

First claim

1 . A system comprising an electricity meter and a circuit breaker for including in a line connecting an electricity distribution network to an electrical installation, the electricity meter comprising:
a primary processor component arranged to acquire a primary power supply parameter relating to supplying power to the electrical installation, and, on the basis of the primary power supply parameter, to produce a primary command for controlling opening or closing of the line; a primary transceiver arranged to transmit the primary command; the circuit breaker comprising: a cut-off member for cutting off the line; a bistable relay arranged to open or to close the cut-off member; a secondary receiver arranged to receive the primary command; a secondary processor component arranged to acquire the primary command and to control the bistable relay so as to open or close the cut-off member as a function of the primary command.

2 . The system according to claim 1 , wherein the primary power supply parameter comprises an opening request or a closing request produced by equipment external to the system and received by the primary processor component of the electricity meter via the primary transceiver.

3 . The system according to claim 1 , wherein the primary power supply parameter is a measurement of primary phase current, and/or a measurement of primary neutral current, and/or a measurement of primary voltage as taken by the electricity meter.

4 . The system according to claim 1 , wherein the secondary processor component is also arranged to acquire a secondary power supply parameter relating to supplying power to the electrical installation, and, on the basis of the secondary power supply parameter, to produce a secondary command for causing the line to be opened or closed, and to control the bistable relay in such a manner as to open or close the cut-off member as a function of the secondary command.

5 . The system according to claim 1 , wherein the primary transceiver is a powerline carrier transceiver and the secondary receiver is a powerline carrier receiver.

6 . The system according to claim 5 , wherein the primary transceiver is a two-band transceiver and the secondary receiver is a single-band receiver.

7 . The system according to claim 1 , wherein the circuit breaker includes a secondary voltage sensor arranged to measure a downstream voltage downstream from the cut-off member.

8 . The system according to claim 1 , including means for pairing the electricity meter and the circuit breaker.

9 . An electricity meter for including in a line connecting an electricity distribution network to an electrical installation, and arranged to be connected to a circuit breaker, the electricity meter comprising:
a primary processor component arranged to acquire a primary power supply parameter relating to supplying power to the electrical installation, and, on the basis of the primary power supply parameter, to produce a primary command for the circuit breaker, the primary commander being for controlling opening or closing of the line; a primary transceiver arranged to transmit the primary command to the circuit breaker.

10 . A circuit breaker for including in a line connecting an electricity distribution network to an electrical installation, the circuit breaker comprising:
a cut-off member for cutting off the line; a bistable relay arranged to open or to close the cut-off member; a secondary receiver arranged to receive a primary command as produced by an electricity meter included in the line; a secondary processor component arranged to acquire the primary command and to control the bistable relay so as to open or close the cut-off member as a function of the primary command.

11 . The circuit breaker according to claim 10 , wherein the secondary processor component is also arranged to acquire a secondary power supply parameter relating to supplying power to the electrical installation, and, on the basis of the secondary power supply parameter, to produce a secondary command for causing the line to be opened or closed, and to control the bistable relay in such a manner as to open or close the cut-off member as a function of the secondary command.

12 . A monitoring method for monitoring a line connecting an electricity distribution network to an electrical installation, the monitoring method being performed in a circuit breaker according to claim 10 , and the method comprising the steps of:
receiving, via the secondary receiver, a primary command for controlling opening or closing of the line; controlling the bistable relay so as to open or close the cut-off member as a function of the primary command.

13 . The monitoring method according to claim 12 , further comprising the following steps:
measuring a downstream voltage downstream from the cut-off member; if the absolute value of the downstream voltage is greater than a predetermined voltage threshold, and if the primary command is for causing the line to be closed, refusing to close the line.

14 . A computer program including instructions for enabling a processor component of a circuit breaker to perform the monitoring method according to claim 12 .

15 . Storage means wherein they store a computer program including instructions for enabling a processor component of a circuit breaker to perform the monitoring method according to claim 12 .
