Description

Technical Field

[0001] This invention relates to the field of electronic tripping devices, such as electronic circuit breakers, and to the field of contact modules. Background Technology

[0002] Electronic circuit breakers can be, for example, open circuit breakers, and are often abbreviated as ACB (air circuit breaker).

[0003] This type of electronic circuit breaker is known to be equipped with an optional contact module, which typically includes one or more contacts. This contact module, for example, relays at least one piece of information from the electronic circuit breaker to a PLC.

[0004] As is well known, the contact module can take the form of a sub-assembly that forms part of an electronic circuit breaker. To install this type of contact module in an electronic circuit breaker, various components of the electronic circuit breaker must be disassembled and numerous electrical connections made. A disadvantage of this solution is the difficulty in adding the contact module to the electronic circuit breaker.

[0005] Alternatively, the contact module can be formed as a separate entity from the electronic circuit breaker and located outside the electronic circuit breaker, for example, on a DIN rail. The disadvantage of this solution is that it occupies more space in the area surrounding the electronic circuit breaker (such as a distribution cabinet or switchboard). This solution also has the disadvantage of making electrical connections more complex and increasing the risk of poor connections.

[0006] Publication WO2016160307A1 discloses a contact module located at the connection block of an electronic circuit breaker. This solution also has the disadvantage of large size. Summary of the Invention

[0043] As shown in the figure, the component includes at least an electronic tripping device 1 and a contact module 2.

[0044] The electronic tripping device 1 includes at least:

[0045] -At least one power line L,

[0046] - At least one current sensor (not shown) capable of measuring the current flowing in the at least one electric power line L,

[0047] -Electronic trip trigger element 3 ( Figures 2 to 11 ), which is electrically connected to the current sensor,

[0048] - An actuator (not shown) electrically connected to the electronic trip trigger element 3,

[0049] - A cutting mechanism (not shown) comprising at least one pair of cutting contacts (not shown), said at least one pair of cutting contacts being respectively arranged on said at least one power line L, and adapted and configured to be actuated by said actuator to disconnect said at least one pair of cutting contacts.

[0050] The actuator and the cut-off mechanism form an electromechanical power sub-assembly.

[0051] - The cutting-off device 4 includes at least an electromechanical power sub-assembly and the at least one current sensor.

[0052] The electronic trip trigger element 3 is removably mounted relative to the cutting device 4.

[0053] The contact module 2 ( Figure 6 and Figure 7 At least including:

[0054] -At least one electromechanical relay 18( Figure 7 It is arranged to relay at least one piece of information from the electronic trip trigger element 3.

[0055] -At least the first electrical connection device 5 ( Figure 6 and Figure 7 It is configured to be electrically connected to a second electrical connection device 6 included in the electronic trip trigger element 3.

[0056] - At least a third electrical connection device 7, which is configured to be electrically connected to at least one output connector 26 included in the electronic tripping device 1.

[0057] The contact module 2 is a separate entity from the electronic tripping trigger element 3.

[0058] According to the present invention, the component is characterized in that:

[0059] The contact module 2 is positioned relative to the electronic tripping trigger element 3 at installation position P01 ( Figure 4 , Figure 8 and Figure 10 ) and disassembly location P02 ( Figure 5 , Figure 9 and Figure 11 The contact module 2 is removably installed between the contact module 2 and the electronic trip trigger element 3. In the installed position, the contact module 2 is mechanically and electrically assembled with the electronic trip trigger element 3. In the disassembled position, the contact module 2 is mechanically and electrically detached from the electronic trip trigger element 3.

[0060] Furthermore, the contact module 2 and the electronic trip trigger element 3 are designed such that when the contact module 2 moves from the disassembled position P02 to the installed position P01, the contact module 2 and the electronic trip trigger element 3 are electrically and mechanically assembled, and when the contact module 2 moves from the installed position P01 to the disassembled position P02, the contact module 2 and the electronic trip trigger element 3 are electrically and mechanically disassembled.

[0061] Advantageously, in this configuration, the contact module 2 can be integrated into a portion of the electronic tripping device 1 during manufacturing or at a later date during after-sales service. This configuration facilitates the installation of the contact module 2 relative to the electronic tripping device 1 and provides the contact module 2 to be integrated into a portion of the electronic tripping device 1 (i.e., the electronic tripping trigger element 3). By integrating the contact module 2 into the electronic tripping trigger element 3, it is advantageous to access the contact module 2 because the electronic tripping trigger element 3 is manufactured to be easily accessible without having to disassemble any part of the electronic protection tripping device 1 except for its front panel 13, which can be removed from the disconnecting device 4. Furthermore, the number of operations when assembling the contact module 2, i.e., moving it from the disassembly position P02 to the installation position P01, or when disassembling the contact module 2, i.e., moving it from the installation position P01 to the disassembly position P02, is limited. In fact, when installing the contact module 2, the contact module 2 is simultaneously electrically and mechanically assembled with the electronic tripping trigger element 3. When disassembling the contact module 2, the contact module 2 is simultaneously electrically and mechanically detached from the electronic tripping trigger element 3. In addition, the installation and removal of contact module 2 can be safely performed in terms of electrical connection because there is no need to handle cables or make complex electrical connections.

[0062] Preferably, the contact module 2 is removably mounted relative to the electronic trip trigger element 3 between an installation position P01 and a disassembly position P02, so that the contact module 2 is accessible when the electronic trip trigger element 3 is assembled with the cutting device 4.

[0063] This configuration improves the accessibility of the contact module 2. Thus, even when the electronic trip trigger 3 is assembled with the disconnecting device 4, i.e., during normal use of the tripping device 1, the contact module 2 can be installed or removed without removing the electronic trip trigger 3. This arrangement avoids the need to remove the electronic trip trigger 3 from the disconnecting device 4 and electrically disconnect it when installing the contact module 2 onto the electronic trip trigger 3.

[0064] If the electronic tripping device 1 also includes a front panel 13 that can be removed from the cutting device 4, then the contact module 2 is removably mounted relative to the electronic tripping trigger element 3 so that the contact module 2 is also accessible when the front panel 13 is removed from the cutting device 4.

[0065] Preferably, at installation position P01, the first electrical connection device 5 is electrically connected to the second electrical connection device 6.

[0066] Preferably, at the installation position P01, the first electrical connection device 5 and the second electrical connection device 6 are preferably facing each other.

[0067] Preferably, at the disassembly position P02, the first electrical connection device 5 is electrically disconnected from the second electrical connection device 6.

[0068] Preferably, the first electrical connection device 5 and the second electrical connection device 6 are arranged such that moving from the disassembly position P02 of the contact module 2 to the installation position P01 results in the electrical assembly of the first electrical connection device 5 and the second electrical connection device 6, and are arranged such that moving from the installation position P01 of the contact module 2 to the disassembly position P02 results in the electrical disassembly of the first electrical connection device 5 and the second electrical connection device 6.

[0069] Preferably, the first electrical connection device 5 and the second electrical connection device 6 are selected from plug-and-play or zero-insertion-force electrical connectors or spring connectors.

[0070] Preferably, such as Figures 2 to 11As shown, the electronic trip trigger element 3 includes a first housing 8, the first housing 8 including: an accessible first surface f1, referred to as the front surface, which includes at least one human-machine interface; an accessible second surface f2, referred to as the side surface, which is orthogonal to the first surface f1, and the contact module 2 is removably mounted relative to the second surface f2; and a third surface f3, referred to as the mounting surface, which is opposite to the first surface f1 and arranged to be assembled with the cutting device 4, and is inaccessible when the electronic trip trigger element 3 is assembled with the cutting device 4.

[0071] The “accessible” surface of the electronic trip trigger element 3 refers to the surface that the user can access without removing the electronic trip trigger element 3 from the disconnection device 4 of the electronic trip device 1, such as the first surface f1.

[0072] The “accessible” surface of the electronic trip trigger element 3 can also be understood as the surface that the user can access without removing the electronic trip trigger element 3 from the electronic trigger device 1 and only by removing the front panel 13 of the electronic trigger device 1, such as the second surface f2.

[0073] The "inaccessible" surface of the electronic trip trigger element 3 is a surface that cannot be accessed by the user without removing the electronic trip trigger element 3 from the cut-off device 4 of the electronic trip device 1. For example, the case of the third surface f3.

[0074] Advantageously, this configuration allows the contact module 2 to be accessed from the side via the second surface f2 of the electronic tripping trigger element 3. This results in improved accessibility to the contact module 2. In fact, the contact module 2 can be accessed or installed simply by removing the front panel 13.

[0075] Preferably, such as Figure 5 and Figure 9 As shown, the contact module 2 is installed to translate relative to the electronic tripping trigger element 3 along the insertion direction D between the installation position P01 and the disassembly position P02.

[0076] Advantageously, the contact module 2 can be easily mechanically assembled relative to the electronic trip trigger element 3 by a simple translational movement in the insertion direction D in the form of a sliding movement.

[0077] Preferably, the contact module 2 is mounted to translate relative to the electronic tripping trigger element 3 in an insertion direction D that is substantially perpendicular to the second surface f2.

[0078] Preferably, the contact module 2 includes a first linear guide 11, which is arranged to cooperate with a second linear guide 12 included in the electronic trip trigger element 3 to allow the contact module 2 to translate between the mounting position P01 and the dismounting position P02, and to mechanically assemble the contact module 2 into the electronic trip trigger element 3 in the mounting position P01.

[0079] Preferably, the first linear guide device 11 and the second linear guide device 12 extend in a straight line parallel to the insertion direction D.

[0080] Preferably, the first linear guide 11 has a shape complementary to that of the second linear guide 12, so as to enable mechanical assembly.

[0081] Preferably, the first linear guide device 11 and the second linear guide device 12 are selected from a groove or a tongue. Preferably, the groove or tongue extends in a straight line parallel to the insertion direction D.

[0082] Preferably, the first linear guide device 11 is located on or inside the first housing 8 of the electronic trip trigger element 3.

[0083] Preferably, the second linear guide device 12 is located on the second housing 9 of the contact module 2 described below.

[0084] Preferably, the contact module 2 includes a second housing 9 that at least accommodates the electromechanical relay 18, and the first housing 8 includes a receiving region 10 for receiving the second housing 9, the receiving region 10 being arranged to at least partially receive the second housing 9. Figure 11 ).

[0085] Advantageously, the receiving area 10 can accommodate all or part of the second housing 9 of the contact module 2. Therefore, the contact module 2 is wholly or partially housed within a portion of the electronic trip trigger element 3. This results in a particularly compact arrangement.

[0086] Preferably, the receiving area 10 extends at least to the second surface f2 of the first housing 8.

[0087] Preferably, the first housing 8 includes an opening 14 on the second side surface f2, which provides a passage to the receiving area 10 and allows the contact module 2 to be inserted into the receiving area 10 in the insertion direction D.

[0088] Preferably, the first linear guide device 11 is arranged in the receiving area 10, for example, on the wall of the receiving area 10.

[0089] Preferably, such as Figure 11As shown, the first housing 8 includes an opening 15 on the third mounting surface f3, thereby providing access to the receiving area 10 but not allowing insertion of the contact module 2.

[0090] When the contact module 2 is not mounted on the electronic trip trigger element 3, the contact module 2 can be replaced by an empty housing (not shown) of the same size as the second housing 9, so that the receiving area 10 can be filled, and in particular the second electrical connection device 6 can be protected.

[0091] Preferably, the receiving area 10 includes a housing that fully or partially matches the shape of the second housing 9 of the contact module 2.

[0092] Preferably, the second electrical connection device 6 of the electronic trip trigger element 3 extends into the receiving area 10. Figure 11 ).

[0093] Preferably, such as Figure 6 and Figure 9 As shown, the first electrical connection device 5 of the contact module 2 extends from the second housing 9. For this purpose, the second housing 9 may include a first access opening 16 through which the first electrical connection device 5 is arranged at least partially.

[0094] Preferably, the third electrical connection device 7 of the contact module 2 extends from the second housing 9. For this purpose, the second housing 9 may include a second access opening 17 through which the third electrical connection device 7 is arranged at least partially.

[0095] The third electrical connection device 7 may include at least one electrical harness 19, which includes a plurality of cables and at least one connector 20 for connection to the at least one output connector 26 included in the electronic tripping device 1.

[0096] The third electrical connection device 7 is configured to connect to the at least one output connector 26, which allows signals from the contact module 2 and therefore from the electronic trip trigger element 3 to be recovered for subsequent processing, for example, by a PLC outside the electronic trip device 1. Figures 3 to 5 As shown, the at least one output connector 26 may consist of a first connecting rail comprising multiple connectors. This first connecting rail is typically mounted on the upper part of the cutting device 4 and arranged behind the front panel 13. Therefore, as... Figure 1 and Figure 2As shown, when the front panel 13 is mounted on the cutting device 4, the at least one output connector 26 is inaccessible. To facilitate signal recovery, the electronic tripping device 1 may further include a second connecting rail 27, which is provided with multiple connectors, each electrically connected to a connector on the first connecting rail. This second connecting rail 27 is accessible when the front panel 13 is mounted. The second connecting rail 27 may be located on top of the cutting device 4, above the first connecting rail. Instead of being positioned behind the front panel 13, the second connecting rail 27 is positioned behind the cover 28 mounted on the cutting device 4.

[0097] Preferably, the contact module 2 includes one or more electromechanical relays 18, each electromechanical relay being used to relay at least one piece of information from the electronic trip trigger element 3.

[0098] The relayable information consists of the operating status of the electronic trip trigger element 3, such as warnings, alarms, or electrical faults detected by the electronic trip trigger element 3. These statuses have "default" operations and can also be modified by the user depending on the version of the electronic trip trigger element 3.

[0099] Preferably, the contact module 2 includes at least one monostable or bistable electromechanical relay 18.

[0100] Therefore, the use of a backup power supply is advantageously avoided so that the electronic tripping device 1 remains in contact after tripping.

[0101] Preferably, such as Figure 7 As shown, the contact module 2 includes an electronic board 21, an electromechanical relay 18, the first electrical connection device 5, and the third electrical connection device 7 connected to the electronic board.

[0102] like Figures 1 to 3 As shown, the electronic tripping device 1 is preferably an electronic circuit breaker, which can be, for example, an open circuit breaker, and is often abbreviated as ACB (air circuit breaker).

[0104] - At least one electromechanical relay 18, designed to relay at least one piece of information from the electronic trip trigger element 3,

[0105] - At least a first electrical connection device 5, which is configured to be electrically connected to a second electrical connection device 6 included in the electronic trip trigger element 3.

[0106] - At least a third electrical connection device 7, which is configured to be electrically connected to at least one output connector 26 included in the electronic tripping device 1.

[0107] According to the present invention, the contact module 2 is characterized in that it is removably mounted relative to the electronic trip trigger element 3 between an installation position P01 and a disassembly position P02, wherein in the installation position the contact module 2 is arranged to be mechanically and electrically assembled to the electronic trip trigger element 3, and in the disassembly position the contact module 2 is arranged to be mechanically and electrically disassembled from the electronic trip trigger element 3.

[0109] Preferably, the contact module 2 includes a second housing 9 that at least accommodates the electromechanical relay 18, and, if applicable, an electronic board 21 to which the at least one electromechanical relay 18, the first electrical connection device 5, and the third electrical connection device 7 are connected.

[0110] Preferably, the first electrical connection device 5 of the contact module 2 extends from the second housing 9. For this purpose, the second housing 9 may include a first access opening 16 through which the first electrical connection device 5 is arranged at least partially.

[0111] Preferably, the third electrical connection device 7 of the contact module 2 extends from the second housing 9. For this purpose, the second housing 9 may include a second access opening 17 through which the third electrical connection device 7 is arranged at least partially.

[0114] Of course, the present invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications can still be made without departing from the scope of protection of the present invention, especially in the formation of various elements or by substitution with technical equivalents.
