It may be useful to add supplementary functions to this type of power device. Typically, these supplementary functions are usually achieved by devices called auxiliary devices that do not form part of the power circuit breaker apparatus, due to the size of the power components providing these supplementary functions. These auxiliary devices may therefore take the form of additional modules fixed to the modular switchboard bank in the same way as the power circuit breaker apparatus, or may take the form of elements different from the power apparatus mounted to the modular switchboard bank, for example to the nameplate frame. The auxiliary additional modules have the disadvantage of occupying undesirable additional space on the modular switchboard row housing the auxiliary additional modules, and they also involve complex and cumbersome installations requiring the intervention of a dedicated installer for the wiring.

Detailed Description
Modular power circuit breaker comprises at least one casing B in which are housed:
a first phase line L, located between at least a first connection terminal 1 capable of and intended to be connected to a distribution power source and a second connection terminal 2 intended to be connected to a load, comprising a pair of contacts, respectively a fixed contact 3 and a mobile contact 4 (figures 1 and 2),
a second neutral line N, located between at least a third connection terminal 5 able and intended to be connected to a distribution power source and a fourth connection terminal 6 intended to be connected to a load (figures 1 and 2),
a trigger lock 7, which trigger lock 7 comprises an operating mechanism 8 projecting from the front face F1 of the housing B for manually actuating the trigger lock 7 and comprises a mobile contact carrier 9 on which the mobile contact 4 is mounted, and which trigger lock 7 is configured to adopt a first position P1 in which the fixed contact 3 and the mobile contact 4 are in contact, and a second position P2 in which the fixed contact 3 and the mobile contact 4 are separated from each other (fig. 1, 2, 4 and 5),
the first phase line L comprises at least one magnetic triggering device 10, said at least one magnetic triggering device 10 being able and designed to actuate the trigger lock 7 to switch the trigger lock 7 from the first position P1 to the second position P2 (figures 1 and 2) in the event of a fault of the short-circuit type,
at least one electric transformer 11, said at least one electric transformer 11 being associated with a first electronic circuit 12 configured to perform a differential function, the first electronic circuit 12 being able and intended to be supplied between the first phase line L and the second neutral line N, and the first electronic circuit 12 being electrically connected to a control mechanism 13 for controlling an electromagnetic actuator 10', the electromagnetic actuator 10' being able and designed to actuate the trigger latch 7 to switch the trigger latch 7 from the first position P1 to the second position P2 in the event of a differential fault.
According to the present invention, the power equipment is characterized by comprising:
a measuring device 14, which measuring device 14 is housed inside said casing B, the measuring device 14 comprising measuring sensors 15, 15' and a second electronic circuit 16, the measuring sensors 15, 15' being able and intended to measure at least the intensity value of the current flowing only on the first phase line L, the second electronic circuit 16 being electrically connected to said measuring sensors 15, 15', the second electronic circuit 16 being able and intended to be supplied between the first phase line L and the second neutral line N, and the second electronic circuit 16 being configured to determine, by comparing the measured current intensity value with a predetermined current intensity threshold value, a triggering threshold value for which the control mechanism 13 is able and designed to control the electromagnetic actuator 10', the electromagnetic actuator 10' being able and designed to actuate the trigger lock 7 to switch the trigger lock 7 from the first position P1 to the second position P2 in the event of a fault of the overcurrent type for a long time (fig. 1, 2, 4 and 5).
Advantageously, the inclusion of the measuring device 14 housed inside said casing B allows to provide a modular power circuit breaker with complementary electronic measuring functions, without affecting the modular form of the power equipment and without requiring the use of additional auxiliary modules. Thus, undesired occupation of modular spaces or wiring areas within the switchboard in which the circuit power breaker device according to the present invention is designed to be installed is avoided. The total installation time is also limited since no additional wiring operations are required. This allows a very simple installation and implementation without any usual measures in comparison with products known from the related art. The installation of the electrical apparatus according to the invention can be done in a few minutes without tools. Advantageously, the measuring device 14 allows, by means of the measuring sensors 15, 15', the measurement of the intensity value of the current flowing in the first phase line L. The measuring sensor 15, 15' is also electrically connected to a second electronic circuit 16, which second electronic circuit 16 allows processing of data relating to the measured current intensity value, in particular allows comparing this data with a predetermined current intensity threshold value to determine a trigger threshold value. More specifically, as long as the measured amperage value is less than the predetermined amperage threshold, the trigger threshold is not reached, and in this case the control mechanism 13 does not operate the electromagnetic actuator 10' and the trigger latch 7 remains in the first position P1. In contrast, when the measured current strength value is greater than or equal to the predetermined current strength threshold value, in other words in the event of a long overcurrent, the trigger threshold value is exceeded, and in this case the control mechanism 13 operates the electromagnetic actuator 10', the electromagnetic actuator 10' itself actuating the trigger lock 7 and thus switching the trigger lock 7 from the first position P1 to the second position P2. The measuring device 14 is preferably configured to comply with the standard IEC 61009-1. For example, the predetermined amperage threshold can be in a range between 1.13 times the nominal amperage and 9 times the nominal amperage. Thus, the measuring device 14 provides an electronic function for detecting long-term over-currents. Advantageously, in this configuration, the need to use a bimetallic strip type thermal trigger mechanism to detect long term overcurrent type faults, which is typically employed.
The invention therefore advantageously extends to a power circuit breaker apparatus as defined previously, which in the sense of the invention only comprises the measuring device 14 to implement the function for detecting long-time overcurrents. In this case, a thermal trigger mechanism is not included.
Preferably, the electric circuit breaker device of the invention is a differential circuit breaker, of which only the first phase line L is protected from faults.
Preferably, the second neutral line N may include a pair of contact portions (fig. 1 and 2) between the third connection terminal 5 and the fourth connection terminal 6, which are the fixed contact portion 3 'and the moving contact portion 4', respectively. Preferably, the contact portions, respectively the fixed contact portion 3 'and the moving contact portion 4', are also mounted on the moving contact portion carrier 9. Therefore, the contact portions, respectively, of the fixed contact portion 3 'and the moving contact portion 4' and the contact portions, respectively, of the fixed contact portion 3 and the moving contact portion 4 operate between the first position P1 and the second position P2 at the same time.
The power circuit breaker device according to the invention is modular as shown in fig. 3 and therefore has the width of one module, in other words the distance between the two side faces F2 of the housing B of the power circuit breaker device corresponds to a standardized value called module.
According to a preferred variant embodiment of the invention, shown in fig. 2, the measuring sensor is a resistance heating measuring sensor 15'. According to this preferred variant embodiment of the invention, the resistance-heated measuring sensor 15' may be a shunt (shunt). Preferably, in this case, the first phase line L comprises a resistance-heated measuring sensor 15' connected in series.
According to another preferred variant embodiment of the invention, shown in fig. 1, the measuring sensor is a power transformer 15.
According to this preferred variant embodiment of the invention, the power transformer 15 may comprise a Rogowski coil (Rogowski coil) through which only the first phase line L passes.
Advantageously, the shunt-type resistance heating measuring sensor 15' has the advantage of being compact, in particular more compact, in particular thinner, than the rogowski coil. As an example, the shunt may have dimensions of 15 mm x 5 mm x 1 mm, while the coil typically has a diameter of about 1.5 cm and a thickness of 5 mm.
The invention also extends to a measuring device 14 according to the invention, for which measuring device 14 the measuring sensor is a measuring sensor that does not comprise a power transformer.
According to another preferred variant embodiment of the invention, the measuring device 14 also comprises a voltage measuring sensor (not shown) which is able and intended to measure the value of the voltage by the current between the first phase line L and the second neutral line N and which is electrically connected to the second electronic circuit 16.
Advantageously, the measuring device 14 also allows measuring the voltage between the first phase line L and the second neutral line N by means of a voltage measuring sensor. This can therefore be done by means of the measuring device 14 to achieve a power consumption measurement.
In this case, the second electronic circuit 16 of the measuring device 14 may be configured to provide a function for detecting overvoltages and/or a function for detecting undervoltages. The second electronic circuit 16 is then configured to determine at least one triggering threshold value by comparing the measured voltage value with at least one value of a predetermined threshold voltage, for which the control mechanism 13 is able and designed to control the electromagnetic actuator 10', the electromagnetic actuator 10' being able and designed to actuate the triggering lock 7 to switch the triggering lock 7 from the first position P1 to the second position P2 in the event of an overvoltage or undervoltage type of fault.
The first value of the predetermined threshold voltage may determine a trigger threshold in the event of an under-voltage condition. In this case, the undervoltage threshold is crossed if the measured voltage value is lower than a first value of the predetermined threshold voltage. The first value of the predetermined threshold voltage may be, for example, equal to 80 volts. The second value of the predetermined threshold voltage may determine a trigger threshold in the event of an overvoltage. In this case, the overvoltage threshold is crossed if the measured voltage value is higher than a first value of the predetermined threshold voltage. The second value of the predetermined threshold voltage may be, for example, equal to 285 volts.
For example, the voltage measurement sensor may comprise a voltage divider bridge.
According to another preferred variant embodiment of the invention, shown in fig. 1 and 2, the first phase line L comprises, in series, at least one thermal trigger mechanism 17, said at least one thermal trigger mechanism 17 being able and designed to actuate the trigger lock 7 to switch the trigger lock 7 from the first position P1 to the second position P2 in the event of a fault of the overcurrent type for a long time.
Advantageously, the thermal triggering mechanism 17 ensures safety in the absence of a voltage for supplying power to the second electronic circuit 16 of the measuring device 14 or a failure of the second electronic circuit 16. Thus, by retaining the thermal trigger mechanism 17, it is ensured at any time that the first phase line L to be protected is open in the event of an overcurrent for a long time. As a result, safety is improved by means of a double monitoring of the overcurrent due to the combination of the thermal trigger mechanism 17 and the measuring device 14 which performs the electronic measurement.
According to this preferred variant embodiment of the invention shown in fig. 5, the thermal trigger mechanism 17 may comprise a bimetallic strip connected to the mobile contact 4 by a flexible conductor 17 'or not connected to the mobile contact 4 by a flexible conductor 17' and able and designed to actuate the trigger latch 7 under the effect of the deformation of the bimetallic strip.
Advantageously, the bimetal strip is deformed by direct or indirect heating of the flexible conductor 17'.
Preferably, the flexible conductor 17' is a conductive braid.
In this configuration, the bimetal strip may have a more compact size than the bimetal strip commonly used in the related art modular power circuit breaker apparatus because of the lower sensitivity required. This is because the bimetal strip is only used to strengthen the measuring device 14 in the absence of a voltage for supplying power to the second electronic circuit 16 of the measuring device 14 or in the event of a failure of the second electronic circuit 16.
According to another preferred variant embodiment of the invention, the second electronic circuit 16 of the measuring device 14 further comprises a communication module 18, the communication module 18: for transmitting data relating to the values measured by the measuring sensors 15, 15'; and/or for receiving data relating to parameter settings of the second electronic circuit 16, preferably at least relating to a predetermined current intensity threshold.
Advantageously, the addition of the communication module 18 allows for remote configuration or reconfiguration of the second electronic circuit 16. For example, a predetermined amperage threshold or other parameter from the second electronic circuit 16 may be set remotely via the communication module 18. Accordingly and accordingly, the communication module 18 allows for remote setting of parameters of the measurement device 14. Furthermore, this communication module 18 allows to obtain data relating to the current intensity values measured by the measuring sensors 15, 15' and, when relevant, to the voltage values measured by the voltage measuring sensors, and any other data processed by the second electronic circuit 16.
Thus, the communication module 18 may include an antenna, the communication module 18 preferably being radio frequency.
According to one advantageous variant embodiment of the invention, the second electronic circuit 16 of the measuring device 14 is configured to implement the function for detecting an arc by means of the power transformer 11 and the measuring sensors 15, 15' associated with the second electronic circuit 16.
Advantageously, in this configuration, the measuring means 14 allow to provide a specific function for preventing faults of the arc type by means of the power transformer 11 associated with the first electronic circuit 12 and the measuring sensors 15, 15' associated with the second electronic circuit 16. Thus, when a dangerous arc is detected, the measuring device 14 may actuate the trigger lock 7 to switch the trigger lock 7 from the first position P1 to the second position P2. In practice, the second electronic circuit 16 is configured to distinguish the arc judged to be dangerous from other arcs, to avoid false triggering of the power circuit breaker device. More particularly, the second electronic circuit 16 is configured for monitoring and analyzing the shape of the current signal measured by means of the power transformer 11 and the measuring sensors 15, 15' to detect abnormal shapes of the current signal representative of dangerous arcs. Advantageously, such an additional function for detecting arcs allows the safety of the electrical installation protected by means of the power circuit breaker device according to the invention to be improved, in particular protected from fire.
