[0001] The invention relates to the field of electrical equipment, preferably for protection, the field of installations comprising such electrical equipment and a remote communication unit, and the field of methods for displaying visual information in such electrical equipment.

[0002] In electrical distribution systems, it is common to install a plurality of electrical protective devices next to each other, for example in an electrical distribution panel.

[0003] It is known that electrical protective devices can communicate remotely with a smartphone using near-field communication (NFC) technology. In this regard, publication US2014170971A1 discloses an electrical distribution system in which information is communicated to and / or from an electrical component of the distribution system, such as a switch, via near-field communication. The information can be communicated to and / or from the electrical component using a remote near-field communication unit, for example, a smartphone.

[0004] However, when applying this solution to multiple electrical devices, it is not possible to reliably determine which protective electrical devices the remote communication unit is communicating with via the near field. It should be noted that protective electrical devices are generally installed in an electrical distribution panel, where they are positioned very close to one another. As a result, the NFC antennas of the various electrical devices can be almost touching and located less than one centimeter apart in the most critical situation.

[0046] [Fig.6] [Fig.6] represents a diagram of a method for displaying visual information in at least one electrical device to identify the execution of a command.

[0047] As illustrated in [Fig. 1], a preferably protective electrical device 1 comprises at least:

[0048] - an electrical line (not shown) arranged to be connected to the electrical network or an auxiliary source,

[0049] - a wireless communication module 2 comprising at least a first receiver 3 configured to receive a near-field electromagnetic (EM) field from a remote communication unit 4 comprising at least a second transmitter 5 configured to emit the electromagnetic field EM which is separate from and at a distance from the electrical equipment 1,

[0050] the wireless communication module 2 being at least configured to be electrically powered by energy captured EN from the intensity of the electromagnetic field EM of the second transmitter 5,

[0051] - at least one indicator light 6 configured to emit at least one signal luminous SL to provide at least some visual information

[0052] - a casing 7 through which at least one electrical line passes and which contains inside at least the wireless communication module 2 and at least one indicator light 6 mounted in the housing 7 so that at least one indicator light SL is visible from outside the housing 7 and preferably from a front face 8 of the housing 7.

[0053] In accordance with the invention, the electrical equipment 1 is characterized:

[0054] - in that it comprises a control module 9 contained in the housing 7 connected electrically to the first receiver 3 and to at least one indicator light 6,

[0055] - in that the control module 9 is configured to be powered at least by less a part of the energy captured EN at least in the absence of supply by the electrical network or an auxiliary source so as to be suitable and intended to supply at least one light indicator 6.

[0056] Advantageously, the electrical switchgear 1 allows at least one indicator light 6 to be powered by means of a remote communication unit 4, both when the electrical switchgear 1 is connected to the mains power supply or an auxiliary source and, where applicable, powered by the mains power supply or an auxiliary source, and when the electrical switchgear 1 is disconnected from the mains power supply and therefore not powered by it or an auxiliary source, in order to provide a user with visual information in the form of a light signal SL. This solution is therefore particularly reliable since it works even when the electrical switchgear 1 is not powered.

[0057] Indeed, the wireless communication module 2 has the capacity to capture energy from the intensity of the electromagnetic field EM emitted by the second transmitter 5 of the remote communication unit 4, in particular to power the control module 9 and consequently power at least one indicator light 6. This configuration is particularly advantageous when the electrical equipment 1 is not connected to the mains power supply or an auxiliary power source, and the wireless communication module 2 therefore cannot be powered by the mains power supply or the auxiliary power source, or when the electrical equipment 1 is connected to the mains power supply or the auxiliary power source but is not powered by the mains power supply or the auxiliary power source, and therefore the wireless communication module 2 is also not powered by the mains power supply. Conversely, when the electrical equipment 1 is connected and Powered by the mains electricity or an auxiliary source, the wireless communication module 2 can operate in active and / or passive mode. Therefore, in active mode, the control module 9, and thus at least one indicator light 6, can be powered by the mains electricity or the auxiliary source, and in passive mode, the control module 9, and thus at least one indicator light 6, can only be powered by at least a portion of the energy captured from the mains.

[0058] Moreover, the solution has the advantage of being inexpensive in electronic components since it is enough to add a dedicated control module 9 or to reuse a control module 9 already present in the wireless communication module 2.

[0059] Preferably, the control module 9 is configured to control the emission of at least one light signal SL from at least one light indicator 6 by emitting a control signal SC to said at least one light indicator 6 by supplying it with at least a part of the energy captured EN upon receipt of the electromagnetic field EM by the first receiver 3 and, the at least one light indicator 6 is configured to emit at least one light signal SL upon receipt of the control signal SC, so as to provide at least one visual information representative of the supply of the wireless communication module 2 by the energy captured EN from the intensity of the electromagnetic field EM of the second transmitter 5.

[0060] Advantageously, the electrical equipment 1 provides a user with visual information indicating that the wireless communication module 2 is being powered by energy captured EN from the intensity of the electromagnetic field EM of the second transmitter 5, both when the electrical equipment 1 is connected to the mains power supply or an auxiliary source and, where applicable, powered by the mains power supply or an auxiliary source, and when the electrical equipment 1 is disconnected from the mains power supply and therefore not powered by it or an auxiliary source. It is thus possible to provide a reliable visual indication that the wireless communication module 2 is being powered by the captured energy EN. The indicator light 6 illuminates provided that at least a portion of the captured energy EN is sufficient to power the indicator light 6.In summary, this configuration makes it possible to provide a reliable solution for indicating whether the wireless communication module 2 is powered by the energy captured by EN.

[0061] Preferably, the wireless communication module 2 includes at least a first transmitter / receiver 3 to establish a specific bidirectional communication link with the remote communication unit 4 comprising a second transmitter / receiver 5.

[0062] Preferably, the control module 9 is configured to output the SC control signal to at least one indicator light 6 by supplying power to less by at least a part of the energy captured EN, if the specific two-way communication link is established and if a dedicated control signal specifically addressed to the wireless communication module 2 from the remote communication unit 4 is received by the wireless communication module 2, and at least one light indicator 6 is configured to emit at least one light signal SL upon receipt of the control signal SC, so as to provide at least one visual information representative of the establishment of the specific two-way communication link by the electromagnetic field EM between the electrical equipment 1 and the remote communication unit 4.

[0063] Advantageously, the electrical equipment 1 makes it possible to provide a user with visual information representing the presence of a specific two-way communication, both when the electrical equipment 1 is connected to the power grid or an auxiliary source and, where applicable, powered by the power grid or an auxiliary source, and when the electrical equipment 1 is disconnected from the power grid and therefore not powered by it or an auxiliary source. It is thus possible to provide a reliable visual indication for identifying the existence of a specific two-way communication. This configuration makes it possible, in particular, to reliably identify which electrical equipment 1 the remote communication unit 4 is communicating with from among a plurality of electrical equipment 1.Thus, the indicator light 6 illuminates provided that the electrical equipment 1 and the remote control unit 4 have established a specific two-way communication link. This configuration allows for the certain visual identification of which electrical equipment 1 is specifically addressed, which is particularly useful if, for example, parameterization operations such as assignment and / or configuration and / or maintenance and / or diagnostics need to be carried out subsequently.

[0064] Preferably and as illustrated in [Fig.2], the electrical equipment 1 is a circuit breaker type electrical protection equipment comprising a mechanical (not shown) or electronic (not shown) breaking module and preferably an electronic control module (not shown) to cut off said at least one electrical line in the event of a fault detected by the electronic control module.

[0065] Advantageously, the electrical equipment 1 makes it possible to perform a protection function against an electrical fault.

[0066] Preferably, the control module 9 is configured to emit the SC control signal to said at least one indicator light 6, supplying it with at least a portion of the energy captured EN upon receipt of the electromagnetic field EM by the first receiver 3 if at least the electronic control module connected to the control module 9 indicates the existence of a fault, and the at least one indicator light 6 is configured to emit at least one light signal SL upon receipt of the control signal SC, so as to provide at least one visual information representative of the presence of a fault in the electrical equipment 1.

[0067] Advantageously, the electrical switchgear 1 provides a user with visual information indicating the presence of a fault in the electrical switchgear 1, both when the electrical switchgear 1 is connected to the mains or an auxiliary power supply and, where applicable, powered by the mains or an auxiliary power supply, and when the electrical switchgear 1 is disconnected from the mains and therefore not powered by the mains or an auxiliary power supply. This makes it possible to provide a reliable visual indication for identifying the existence of a fault in the electrical switchgear 1. Thus, the indicator light 6 illuminates on the additional condition that a fault has been detected and that this information has been communicated to the control module 9.This information, indicative of the existence of a fault, may have been previously stored in a memory electrically connected to or forming part of control module 9.

[0068] Preferably, the wireless communication module 2 is said to be passive and is configured to be powered electrically exclusively by the energy captured EN and the control module 9 is configured to be powered exclusively by at least a part of the energy captured EN, in the absence and in the presence of power supply of the wireless communication module 2 and the control module 9 by the electrical network or an auxiliary source.

[0069] In this configuration, only the energy captured EN by the wireless communication module 2 from the intensity of the electromagnetic field EM emitted by the second transmitter / receiver 5 of the remote communication unit 4 is used to provide visual information via at least one light indicator 6. Energy from the electrical network or the auxiliary source is never used in this configuration even if it is available.

[0070] Preferably, at least one light indicator 6 comprises at least one light-emitting diode.

[0071] Advantageously, this LED type indicator light solution 6 has the advantage of being inexpensive and consuming little electrical energy, i.e. the consumption is on the order of a few milliamperes, preferably 2 milliamperes.

[0072] Preferably and as illustrated in [Fig.2], the housing 7 is in modular format, that is to say that the modular width is a multiple of a module worth 18 millimeters or 17.5 millimeters.

[0073] Advantageously, in this case the electrical equipment 1 has a compact format with preferably a modular width of one module i.e. 18 millimeters or two modules i.e. 36 millimeters.

[0074] Preferably, the wireless communication module 2 includes the control module 9.

[0077] Preferably, the circuit breaker is an open circuit breaker commonly designated by the acronym ACB (Air Circuit Breaker) or a molded case circuit breaker commonly designated by the acronym MCCB (Molded Case Circuit Breaker) or an additional residual current device commonly designated by the acronym AOB (Add-On Block). This type of circuit breaker is not modular. These examples are not exhaustive.

[0078] The electrical equipment 1 can also be an electrical protection device with electronic cut-off.

[0079] The electronically interrupting protective device may be modular and be, for example, a static modular circuit breaker of the type SCCB (Semi Conductor Circuit Breaker) or a static modular residual current circuit breaker SC-RCBO (Semi Conductor Residual current Circuit Breaker with Overload). These examples are not limiting.

[0080] Preferably, the electrical equipment 1 is arranged so that it can be installed in the electrical distribution panel (not shown).

[0081] Preferably, said at least one electrical line includes at least one electrical conductor which can be supplied, for example, by the electrical network.

[0082] Preferably, the wireless communication module 2 allows, where applicable, the transmission and reception of electromagnetic waves in the near field via near-field technology commonly known as NFC. The wireless communication module 2 can be powered either indirectly and without contact by the remote control unit 4 via near-field communication or directly from the electrical network or an auxiliary power source if the latter is electrically powered. Indeed, the wireless communication module 2 can be electrically powered by the energy captured EN from the intensity of the electromagnetic field EM of the second transmitter 5. The energy captured EN is electromagnetic energy. A portion of the energy captured EN can be used to electrically power the control module 9 and the indicator light 6.This portion of the captured energy EN may correspond to a portion of the captured energy EN that was not consumed by the wireless communication module 2. The wireless communication module 2 may include either the first receiver 3 or the first transmitter / receiver 3. In the . In the first case, the wireless communication module 2 can establish at least one unidirectional communication link with the remote control unit 4. In the second case, the wireless communication module 2 can establish at least one unidirectional or bidirectional communication link with the remote control unit 4, with bidirectional communication possible provided that the latter is equipped with the second transmitter / receiver 5. The first receiver 3 or the first transmitter / receiver 3 is electrically connected to the control module 9 either directly or indirectly. In the latter case, a storage unit is preferably located between the first receiver 3 or the first transmitter / receiver 3 and the control module 9, as detailed below.

[0083] Preferably, the wireless communication module 2 conforms to the IEC15693 standard.

[0084] Preferably, the first receiver 3 or the first transmitter / receiver 3 includes at least one antenna 10.

[0085] The remote control unit 4 is preferably a smartphone, tablet, or laptop computer. The remote control unit 4 preferably includes a display 11, for example, a screen.

[0086] The second transmitter / receiver 5 enables the transmission and reception of electromagnetic waves in the near field via near-field technology commonly known as NFC. The remote control unit 4 and the wireless communication module 2 can exchange electromagnetic signals remotely. The second transmitter / receiver 5 can power the wireless communication module 2. The remote communication unit 4 can include either a second transmitter 5 or a second transmitter / receiver 5. In the first case, the remote communication unit 4 can establish at least one unidirectional communication link with the remote control unit 4. In the second case, the remote communication unit 4 can establish at least one unidirectional or bidirectional communication link with the wireless communication module 2, the communication being bidirectional provided that the latter is equipped with the first transmitter / receiver 3.

[0087] The remote control unit 4 preferably includes a microcontroller (not shown).

[0088] The indicator light 6 is designed to emit at least one light signal SL. The indicator light 6 can operate even after the electromagnetic field EM is interrupted and the remote communication unit 4 is moved away, as long as at least a portion of the previously recovered energy EN remains sufficient to allow its operation. The light signal SL can be continuous, discontinuous, or modulated. The light signal SL can be emitted at different wavelengths. The indicator light 6 can be powered by at least one Part of the energy captured EN is supplied via the control module 9, which is powered either directly by it or indirectly from it via a storage unit (not shown). In the latter case, the storage unit is electrically connected to the first transmitter / receiver 3 to store at least part of the captured energy EN and to the control module 9 to provide its power supply. The storage unit may have at least one capacitor. The storage unit is configured to store electrical energy, which may be at least part of the captured energy EN that has not been consumed. The advantage of the storage unit is that it allows for the accumulation of energy that can be released later, which, for example, allows the indicator light 6 to be powered for a longer period or to power an indicator light 6 that consumes more energy than an LED.

[0089] The housing 7 preferably includes an opening 12 on the front face 8. The indicator light 6 preferably opens at the level of the opening 12.

[0090] The control module 9 is preferably a microcontroller (not shown). The control signal SC powers the indicator light 6 and controls the emission of the light signal SL.

[0092] Advantageously, the second transmitter 5 of the remote communication unit 4 is provided to emit the electromagnetic field EM to enable the power supply of the control module 9 and consequently the power supply of at least one indicator light 6 of at least one electrical equipment 1. The installation makes it possible to provide visual information reliably to a user.

[0093] Preferably, the installation comprises a plurality of electrical devices 1, and the wireless communication module 2 of the electrical equipment 1 is configured to be powered by the energy captured EN from the intensity of the electromagnetic field EM of the second transmitter 5 of the remote communication unit 4.

[0094] In this configuration, the second transmitter / receiver 5 of the remote communication unit 4 is intended to emit the electromagnetic field EM for to allow the control module 9 to be powered and consequently the power supply to at least one indicator light 6 of the plurality of electrical devices 1.

However, in this configuration, it is not necessarily possible to visually identify with certainty which electrical equipment 1 is being addressed because the light indicator 6 of each electrical equipment 1 in the electromagnetic field EM will emit a light signal SL.

[0097] Alternatively, the installation allows, in particular, for providing a user with several visual information pieces representing, in visible form, a plurality of bidirectional communication links via the electromagnetic field EM. Each link is between all, or only one or some, of the electrical devices 1 and the remote communication unit 4. In this configuration, it is possible to address the communication to a single specific electrical device 1 and thus to visually identify with certainty which electrical device 1 is being addressed, since only the indicator light 6 of this specific electrical device 1 in the electromagnetic field will emit a light signal SL

[0098] Preferably the installation further includes an electrical distribution panel in which the plurality of electrical equipment 1 is installed, the electrical equipment 1 being placed side by side on at least one row R and the remote communication unit 4 being preferably located away from the electrical distribution panel.
