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.
Claims12
A system comprising an electricity meter and a circuit breaker, separate from and in communication with the electricity meter, 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;
- and
- a primary transceiver arranged to transmit the primary command,
- wherein the circuit breaker comprises:
- 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 voltage sensor arranged to measure a downstream voltage downstream from the cut-off member;
- and
- 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,
- 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, and
- wherein the circuit breaker is arranged to:
- measure the downstream voltage;
- and
- 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, refuse to close the line.
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 on the basis of a primary power supply parameter;
- a secondary voltage sensor arranged to measure a downstream voltage downstream from the cut-off member;
- and
- 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,
- 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, and
- wherein the circuit breaker is arranged to:
- measure the downstream voltage;
- and
- 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, refuse to close the line.
