Description

Title of the invention: ELECTRICAL CABINET AND MANAGEMENT METHOD ELECTRICAL MODULE MAINTENANCE technical field

[0001] This description relates to an electrical cabinet and a method for managing the maintenance of electrical modules. Previous technique

[0002] It is common practice to install electrical equipment in dedicated cabinets, commonly called electrical cabinets or switchboards, in the form of electrical modules that are inserted into designated slots in each electrical cabinet. The design of each electrical cabinet and the electrical modules may be defined by a standard to ensure their compatibility. Most often, each cabinet is intended to remain permanently at an installation or operating site, and each module may be removed from its slot in the cabinet for various reasons, including performing tests or measurements on the module, exchanging the module for a replacement module, removing the module for maintenance, etc.

[0003] For example, an electrical module can be dedicated to the operation of an electrical device such as a pump, a motorized valve, a fan, etc. For this purpose, the module can be of two types: a power module, whose function is to supply the electrical power to the device, or a control module, whose main function is to activate and interrupt the operation of the electrical device. Generally, the power module also performs certain safety functions, including leakage current detection, detection of excessive electrical currents delivered to the device, and circuit breaker operation. The control module may also allow for parameter setting of the operation of the electrical device in question.

[0004] Module slots in an electrical cabinet are often aligned in rows or stacked in columns, for example, twelve stacked slots. In a common column arrangement of an electrical cabinet, the module slots are paired horizontally within each pair, with one slot in a pair intended to receive a power electrical module and the other slot in the same pair intended to receive a... Control and command. All control and command electrical modules are preferably stacked in a single column, just as all power electrical modules are stacked in an adjacent column. However, the design of the electrical cabinet may allow at least some of its locations to be used alternately for a power electrical module or a control and command electrical module, and / or that adjacent locations, particularly those located above each other, may be grouped together to house a larger electrical module.

[0005] However, monitoring the maintenance of all the electrical modules contained within electrical cabinets can be difficult. Indeed, each electrical module may have different maintenance and servicing requirements, for example, a maintenance frequency that depends on the module's function, model, manufacturer, and usage. Managing the maintenance of all the electrical modules contained within an electrical cabinet can therefore be complex, especially since some modules may be identical and differentiated by their respective positions within the cabinet. The risk of confusion between modules is then high, in addition to the risk of failing to schedule maintenance for one of the modules on the prescribed date.

[0006] Document CN 116452182 A relates to the use of RFID tags to track the progress of electrical equipment in manufacturing.

[0007] Throughout this document, the acronym RFID refers to radio frequency identification, as defined by the Gen2 standard or another standard known to those skilled in the art. An RFID tag, sometimes also called an RFID label, comprises an adhesive backing that carries a radio antenna and an electronic chip. The electronic chip is capable of storing information and controlling the transmission by the antenna of radio signals that contain at least some of this information. An RFID reader includes a system for detecting RFID tags that are present near the reader, a system for receiving the information transmitted by each RFID tag, and a system for wirelessly transferring power from the RFID reader to the RFID chip when the latter lacks an internal power source. RFID readers / writers are used to write the information to the chip of each RFID tag.This information is then available to be received by an RFID reader when the RFID tag is within a certain range of the reader. Depending on the model, this range can vary from one centimeter to several meters. RFID equipment, including an RFID reader and at least one RFID tag, is then selected for each application based on the required range. is desired. A minimum range length value is chosen to ensure that the RFID reader and the RFID tag communicate with each other, and a maximum range length value ensures that the RFID reader cannot communicate with RFID tags that are further away. Technical problem

[0008] Based on this situation, one object of the present invention is to facilitate the maintenance management of electrical modules contained in electrical cabinets. Summary of the invention

[0009] To achieve this or another objective, a first aspect of the invention provides an electrical cabinet comprising at least one slot designed to receive an electrical module, and equipped with at least one radio frequency identification (RFID) reader. This RFID reader is arranged such that if the electrical module is equipped with a radio frequency identification (RFID) tag, the RFID reader receives information from the RFID tag when the electrical module is in the slot and the RFID reader is activated.

[0010] Thus, the collection of information concerning the electrical module can be carried out without an operator physically intervening to consult the electrical module in situ and / or to retrieve the information from the control cabinet. This results in significant savings in time and labor costs, particularly for managing the maintenance of the electrical module.

[0011] Generally, for the purposes of the invention, the electrical cabinet can be designed so that the electrical module is removable within its slot, allowing it to be removed and / or exchanged with another electrical module in the same slot. When the new module is also equipped with an RFID tag, the information received by the RFID reader is automatically changed from that of the initial module to that of the new module. This avoids the risk of failing to update the information relating to the electrical module actually located in the slot inside the cabinet. A database of the installed equipment, containing information on the type of each installed electrical module, its location in the electrical cabinet or panel, and the type of the electrical cabinet or panel, can thus be automatically updated.Precise knowledge of the installed equipment and its location is thus available. The invention therefore makes it easier to meet prescribed safety and maintenance requirements for an installation that includes the electrical cabinet. In particular, the invention can be especially advantageous for an installation that is part of a nuclear power plant.

[0012] In earlier embodiments of the invention, the electrical cabinet may include several locations, each designed to receive a respective electrical module, and the RFID reader may be arranged so that if any of the locations contains an electrical module equipped with an RFID tag, the RFID reader receives information from the module's RFID tag when the RFID reader is activated. In other words, the RFID reader may be common to several locations or to all locations in the electrical cabinet. In this case, an identification of the location where one of the modules is situated may advantageously be inscribed in the RFID tag of that module, so as to be received by the RFID reader in the information for the module concerned.Such initial embodiments can be particularly suitable when the electrical cabinet is of the type of electrical power distribution panel operating at 230 V AC voltage, or at 125 V, 48 V or 24 V DC voltage. Indeed, it is not necessary to have a separate RFID reader for each location in the electrical cabinet, which is compatible with a compact arrangement of module locations within the electrical cabinet.

[0013] In second embodiments of the invention, where the electrical cabinet further comprises several slots, each designed to receive a respective electrical module, these slots may be divided into separate subsets, and the electrical cabinet includes an RFID reader dedicated to each subset, separate from every other subset. Each subset of slots may contain only one slot, or several slots. The RFID reader for each subset is arranged so that if any slot in that subset contains an electrical module equipped with an RFID tag, the RFID reader receives information from the module's RFID tag when the RFID reader is activated. In other words, each RFID reader is dedicated to one of the subsets of slots in the electrical cabinet, being shared among all the slots in that subset.For such second embodiments, the RFID readers can advantageously be arranged relative to the locations of all subassemblies so that each RFID reader is at a separation distance that is less than the effective range length for the RFID reader for each location in the subassembly corresponding to that RFID reader, and greater than the range length for each location not belonging to that subassembly. In this way, each RFID reader, when activated, receives information from an RFID tag of an electrical module only if that electrical module is in any location within the subassembly to which that RFID reader is dedicated, excluding information contained in an RFID tag of another module. The electrical module is located in a different location outside the subset to which the RFID reader is dedicated. Thus, locations within the electrical cabinet are assigned to RFID readers. This assignment further enhances the security of information gathering about the electrical modules contained within the cabinet by reducing the risk of module confusion even further. Each subset could potentially consist of a pair of adjacent locations, comprising a power module location and a control module location, with the RFID reader for each pair positioned between the power module location and the control module location.Such secondary embodiments can be particularly suitable when the electrical cabinet is of the type of three-phase electrical power distribution cabinet with an interphase voltage of 380 V. They allow identification of the equipment installed and its corresponding locations in the electrical cabinet or panel.

[0014] Generally, for the invention, the electrical cabinet may further include a communication gateway adapted to transmit the information received by each RFID reader to a monitoring unit, which may be external or internal to the electrical cabinet, or may further include means for recording and displaying the information received by each RFID reader, or may include both. Remote access to the information contained in the RFID tags is thus possible. The electrical cabinet may also include connection means arranged to transmit the information received by each RFID reader to the communication gateway, or to the means for recording and displaying this information, or to both.These connection methods can advantageously be configured to form, together with the RFID reader(s) and the communication gateway or the recording and presentation devices, an internal communication network within the electrical cabinet. They can also be further adapted to supply each RFID reader with electrical power.

[0015] A second aspect of the invention proposes a maintenance management method for at least one electrical module located in a position inside an electrical cabinet conforming to the first aspect of the invention, an RFID tag being attached to the electrical module, the method comprising:

[0016] - while the electrical module is in the slot, activate the RFID reader so that it receives information from the RFID tag of the electrical module;

[0017] - order a maintenance operation on the electrical module based on the information received by the RFID reader, and possibly by associating this information received by the RFID reader along with usage and operating data from the electrical module; and

[0018] - perform the maintenance operation on the electrical module, possibly by using the information received by the RFID reader and the usage and operating data of the electrical module where applicable.

[0019] The information received by the RFID reader from the RFID tag of each electrical module may include at least one piece of data that is selected from the list including: a date of manufacture of the electrical module or of at least one component thereof, a serial or batch number of the electrical module or of at least one component of the electrical module, a reference of a manufacturer of the electrical module or of at least one component of the electrical module, a date of installation of the module in the electrical cabinet, a date of last maintenance operation of the electrical module, a cumulative operating time of the electrical module, a number of starts and stops of the electrical module, an identification of a device that is powered by the electrical module, including an indication of a type of this device, and optionally an identification of the location of the electrical module in the electrical cabinet.Specifically, the location recorded on each electrical module's RFID tag may depend on whether or not the locations are identified by each RFID reader in the electrical cabinet. This makes it possible to correlate a usage log with each installed electrical module. Brief description of the figures

[0020] The features and advantages of the present invention will become more apparent from the following detailed description of non-limiting embodiments, with reference to the accompanying figures, among which:

[0021] [Fig. 1] shows a first possible embodiment of the invention for an electrical cabinet of the type panel-source for distributing electrical power at 230 V;

[0022] [Fig.2] shows a second possible embodiment of the invention for an electrical cabinet of the type of three-phase electrical power distribution cabinet with an interphase voltage of 380 V; and

[0023] [Fig.3] shows an electrical module that can be used in the second embodiment of the invention of [Fig.2]. Detailed description of the invention

[0024] For the sake of clarity, the dimensions of the elements shown in these figures do not correspond to actual dimensions or actual dimension ratios. Furthermore, some of these elements are represented only symbolically, and Identical references shown in different figures denote identical elements or elements that have identical functions.

[0025] With reference to [Fig. 1], an electrical cabinet 10 comprises rows R of locations 11 for electrical modules. Each location 11, or at least some of them, is occupied by a separate electrical module of the circuit breaker, relay, or contactor type. Reference numeral 1 designates some of these electrical modules, regardless of their respective types. Each electrical module 1 can be installed removably, for example by plugging or "plugging" it into a row rail, in particular so that it can be easily exchanged within the cabinet 10 for a new electrical module in the same location, particularly when the original module is defective or no longer meets the required electrical characteristics, or when the module needs to be checked on an external test bench.With reference to such a replacement operation, each electrical module 1 is sometimes called the moving part, and the cabinet 10, including internal supports therein for installing the modules 1 in the locations 11, is sometimes called the fixed part. Optionally, a module 1 may occupy two adjacent locations 11 inside the cabinet, or more than two adjacent locations, without altering the principle of the invention as described below.

[0026] According to the invention, an RFID tag is affixed, for example by gluing, separately to each electrical module 1. This tag is designated by reference numeral 12 for each module 1. Typically, an RFID tag 12 is permanently affixed to each module 1 during its manufacture and remains attached to the module throughout its lifespan until its destruction. The information stored in the chip of this RFID tag may include the module's manufacturing date, its manufacturer, a serial or batch number of the module, the module's hardware characteristics, etc. This information initially recorded in the RFID tag may be supplemented during the module's lifespan by additional information about the module, such as its installation date in the cabinet 10, dates of verification or maintenance, usage times, the number of start-ups and / or shutdowns, etc.Such additional information can be added to the RFID tag chip using an RFID reader-writer (not shown). [Fig. 1] shows each module 1 contained in the cabinet 10 with its respective RFID tag 12. Once all the modules 1 are placed in the cabinet 10 to begin operation, it is advantageous to also include, among the information stored in each RFID tag 12, an identification of the location 11 where the module 1 bearing that RFID tag is located. This location identification can consist of a number from the row R containing the module's location 11, and a number for that location. 11 inside the row. It will thus be possible to associate each module 1 with its function in an electrical installation which includes the cabinet 10, by combining the location identification which was transmitted by its RFID tag 12 with electrical installation configuration data and electrical wiring data of the cabinet 10.

[0027] For this first embodiment, an RFID reader is installed in the cabinet 10, as designated by reference numeral 2. For example, the RFID reader 2 has a range that is greater than the separation distance between the installation location of this RFID reader 2 in the cabinet 10 and each of the modules 1. Thus, the RFID reader 2, when activated, can successively receive the information stored in the RFID tags 12 of all the modules 1 that are inside the cabinet 10. Advantageously, the cabinet 10 can also be equipped with a communication gateway 3 that is adapted to transmit the information received by the RFID reader 2 to a monitoring unit 20 that is external or internal to the electrical cabinet 10. Optionally, this monitoring unit 20 can be common to several separate electrical cabinets, either at the same installation site or at different sites.The communication gateway 3 provides a transmission interface to a communication network external to the cabinet 10, such as an Ethernet or internet network, including 4G or 5G. Typically, the communication gateway 3 can be a modem. Connection means 4, dedicated to the cabinet 10 and preferably housed within it, can then connect the RFID reader 2 to the communication gateway 3. This allows for remote querying of the RFID tags 12, for example, initiated by an operator or controlled by a maintenance management server or a programmable logic controller (PLC) that constitutes the monitoring unit 20.Optionally, the communication gateway 3 can be replaced by a local terminal for recording and displaying information received by the RFID reader 2 from the RFID tags 12, for example so that this information can be consulted by a maintenance operator.

[0028] This first embodiment is particularly suited to compact electrical cabinet designs, where it is not possible to install RFID readers near all the slots 11 inside the cabinet 10. A resulting drawback is that the slot 11 of each module 1 in the cabinet 10 must be updated in the module's RFID tag 12 each time that module is moved or replaced with a new module. Another embodiment of the invention is now described, which eliminates this drawback.

[0029] With reference to [Fig. 2], an electrical cabinet 10 comprises columns of locations 11, for example four columns C1, C2, C3 and C4. The locations 11 of the columns Cl and C3 can be dedicated to receiving electrical modules 1 of the power module type, and those of columns C2 and C4 dedicated to receiving other electrical modules 1 of the control module type. As before, it is possible for a module 1 to occupy several adjacent locations 11. Typically, columns C1 and C2 can be paired for the operation of the electrical installation to which the cabinet 10 belongs, as well as columns C3 and C4, also paired. Thus, although not essential to the implementation of the invention, two locations 11 that are adjacent in the horizontal direction, one belonging to column C1 (respectively C3) and the other to column C2 (respectively C4), are paired in the operation of the electrical installation. The electrical cabinet model shown in [Fig. 2] is larger than that of [Fig. 1], and each electrical module 1 can then have a drawer configuration to be inserted into one of the locations 11.The electrical cabinet 10 of [Fig. 2] may have an interleaved space between the paired columns Cl and C2 on the one hand, and another interleaved space between the paired columns C3 and C4 on the other. These interleaved spaces may contain structural uprights of the cabinet 10, for example. RFID readers 2 are then affixed to these uprights, preferably on the face of each upright that is turned towards the interior of the cabinet 10, at height levels that correspond one by one to the locations 11 in the columns Cl-C4. Then the location on each electrical module 1 where its RFID tag 12 is attached may have been selected so that this RFID tag 12 comes close to one of the RFID readers 2 when the module 1 is inserted into a location 11 of the cabinet 10. [Fig.Figure 3 shows an electrical module 1 of the power module type intended to be inserted into a slot 11 in column C11 or column C3, with its RFID tag 12 affixed behind the module's front panel 13, near the upper right corner of that front panel. Similarly, an electrical module 1 of the control module type intended to be inserted into a slot 11 in column C2 or column C4 has its RFID tag 12 preferably affixed behind its front panel near the upper left corner. Thus, when two electrical modules 1 are inserted into slots 11 adjacent to the same RFID reader 2, that RFID reader can receive information stored in the RFID tags 12 of those two modules 1.For this reason, the range of the RFID reader 2 must be greater than its separation distance from each of the RFID tags 12 of the two modules 1, typically greater than 3 cm (centimeter). Furthermore, the range of each RFID reader 2 is advantageously chosen to be less than the distance inside the cabinet 10 that separates this RFID reader 2 from the RFID tags 12 of modules 1 that are at any location 11 not adjacent to the RFID reader. 2. Typically, this RFID reader range is less than 15 cm for the electrical cabinet model 10 of [Fig. 2]. Under these conditions, the positions of the slots 11 in the cabinet 10 can be located by the respective identifiers of the RFID readers 2, so that the transmission of information by one of the RFID readers 2 directly indicates the slot 11 where the module 1 to which this information relates is located, by the identifier of that RFID reader 2. It is then unnecessary to manually engrave the identifiers of the slots 11 onto the RFID tags 12 of the modules 1 inserted there. This avoids the risk of confusion between several slots 11 for the same module 1, in addition to the operator time saved by eliminating the operation of engraving the RFID tags 12 after the modules 1 have been placed in the cabinet 10.

[0030] All RFID readers 2 used in the embodiment of [Fig. 2] are connected to the communication gateway 3 by suitable connection means 4, which are preferably dedicated to the cabinet 10. These connection means 4 may include a router connected on one side to the communication gateway 3, and on the other side to each RFID reader 2, by wired connections which may be of the RJ45, RS232, CAN (Controller Area Network) bus type, or other. The connection means 4 can thus form a local communication network that is internal to the cabinet 10. Advantageously, the connection means 4 used to link the RFID readers 2 to the communication gateway 3 also provide each RFID reader 2 with electrical power.Such a combination of data transmission and electrical power delivery functions is commonly referred to as POE, for "Power Over Ethernet" or power supply via Ethernet cable.

[0031] In the embodiment of [Fig. 2], each RFID reader 2 is therefore dedicated to two locations 11. However, it is possible to provide a separate RFID reader for each location 11 if the separation distance condition, which is less than the range length, is met by only one location for that RFID reader. It is also possible to assign the same RFID reader to any number of locations 11. For this purpose, the locations 11 in the cabinet 10 are arranged such that the separation distance between each RFID reader and the RFID tag of a module located in one of the locations assigned to that RFID reader is less than the range length of the RFID reader.Locations where the separation distance from one of the RFID readers is greater than the range length of that RFID reader are assigned to another RFID reader which is also installed in the same electrical cabinet, and also connected by the connection means 4.

[0032] The invention can be particularly useful for managing maintenance of the electrical modules 1 which are contained in the cabinet 10. Indeed, the monitoring unit 20, or a local terminal for recording and presenting information which is used instead, has a usage log for each of the modules 1 contained in the cabinet 10.This usage log, also called a logbook, contains initial manufacturing data for each module, such as a manufacturing date, a serial or batch number of the electrical module or at least one component of the electrical module, a manufacturer's reference, a date of first use or commissioning, a date of installation in the cabinet 10, a date of last maintenance operation of the electrical module, a cumulative operating time, a number of start-and-stop sequences executed by the electrical module, and an identification of the location 11 of the electrical module 1 in the electrical cabinet 10. As a reminder, this location identification can come directly from the RFID tag 12 of the module 1 when it is updated at each new installation of this module, for example for the embodiment of [Fig.1].Alternatively, it can be added to the information received from the RFID tag 12 by the RFID reader 2, which then transmits this information to the monitoring unit 20, for example, in the embodiment shown in [Fig. 2]. This usage log for each module 1 can be periodically analyzed by the monitoring unit 20 or by an operator. Preventive maintenance can thus be scheduled for this module 1 based on the received information, including data on the module's current usage resulting from the identification of its location 11. The execution of the maintenance operation itself may also depend on the content of the module 1 usage log. Such maintenance management of the electrical modules 1, whose safety is improved by the invention, is particularly well-suited to the operation of a nuclear power plant for electricity generation.The usage log may also contain information on the current operating status of a device powered by each module, including an indication of whether that device is functioning correctly or malfunctioning.

[0033] It is understood that the invention can be reproduced by modifying secondary aspects of the embodiments described in detail above, while retaining at least some of the advantages mentioned. Furthermore, all the configurations cited or shown are for illustrative purposes only and may change depending on the application.
