Definitions
- the present invention relates to the general technical field of equipment protection devices or electrical installations against electrical disturbances, especially against transient overvoltages due in particular to a lightning strike.
- the present invention relates more particularly to a protection device, such as a varistor surge arrester, associated with or intended to be associated with an electrical breaking device such as a circuit breaker.
- these devices comprise a disconnection system for isolating the protection component or components of the electrical installation for safety reasons.
- thermal protection is used to disconnect the varistor of the electrical installation to be protected in case of excessive heating of the varistor, for example beyond 150 0 C.
- This excessive heating of the varistor is due to the increase of the current of leakage - usually a few tens of milliamperes - through it due to aging. In this case, it is called thermal runaway of the varistor.
- Thermal protection often consists of one or more low temperature welds holding in place an elastically constrained element, the fusion of the weld or welds allowing the displacement of this element with the effect of opening the circuit of the varistor. Thermal protections of this type are described in particular in EP-A-0 716 493, EP-A-0 987 803 and EP-A-0 905 839.
- thermal protection is also based on an electronic current measurement as described for example in FR-A-2,873,510, which has the drawback of being expensive.
- the disadvantage is that the thermal protection and the short-circuit protection are distinct and each employs a respective breaking device. That of the thermal protection can have a low power of cut while that of the protection against short circuits must be able to cut very high currents. But the fact of using two cut-off devices has the disadvantage of both increasing the size of the protective device and its cost.
- an overvoltage protection device comprising a protection module and a circuit breaker.
- the protection module comprises a varistor and a spark gap, which are connected to the electrical network to be protected by means of the circuit breaker.
- the protection module comprises separation means to cause the opening of the circuit breaker. More specifically, these separation means consist of a thermal pin disposed on a range in thermal connection with the varistor and an electric fuse connected in series with the spark gap.
- the thermal pin is made of metal alloy or heat-fusible material low melting temperature.
- a mechanical actuation system ensures the tripping of the circuit breaker and consequently the disconnection of the varistor and the spark gap of the electrical network. More particularly, the mechanical actuation system comprises a lever connected to the thermal pin and another lever connected to the fuse, these levers being biased by a respective return spring. In the case where the pin or fuse melts or breaks, the corresponding lever acts on a control centralizer under the effect of the return spring, the control centralizer actuating the trigger mechanism of the circuit breaker through a mechanical connection.
- EP-A-1 447 831 describes a lightning surge protection device combining a surge arrester block and a magnetothermic circuit breaker, the surge arrester block comprising a varistor. According to one embodiment, the arrester block comprises a thermal disconnector thermally connected to the varistor 12.
- the thermal disconnector is constituted by a low temperature weld cooperating with an elastic blade triggering the circuit breaker after fusion of the weld under the effect of heat a thermal runaway of the varistor.
- This embodiment has disadvantages similar to those mentioned above for the metal alloy heat pin.
- this document teaches to thermally connect the bimetallic circuit breaker to the varistor. If the bimetallic strip of the circuit breaker does not undergo a sufficient deflection when it is crossed by the currents appearing during the thermal runaway of the varistor, the thermal connection between said varistor 12 and the bimetallic strip generates a sufficient deflection to cause the tripping of the circuit breaker which disconnects the surge arrester block from the electrical network. But this embodiment also has disadvantages. In particular, it is not possible to use conventional commercial circuit breakers because they are not intended to thermally connect their bimetallic to an element outside the circuit breaker housing. Such a device requires modifying the design of the circuit breaker to be able to effectively communicate the heat generated by the varistor at the bimetallic circuit breaker. In addition, the circuit breaker can not be chosen freely considering that the bimetallic thereof must be adapted to cause the tripping of the circuit breaker at a given critical temperature reached by the varistor.
- this interruption means comprises a sliding rod carrying an electrical contact element for opening or closing the electrical circuit of the varistor.
- the rod is prestressed in the closed position of the contact by a stop in the form of a plate arranged at the end of a bimetallic strip.
- the bimetal is mounted and positioned in the device to be sensitive to heat released by the varistor. In case of excessive heating, the bimetallic bends so as to disengage the stop to release the rod which is biased by a spring towards the open position of the contact.
- the varistor is fed through the bimetal and a conductive element arranged at one end of the bimetallic strip.
- this conductive element is in electrical contact with a connector, which allows to feed the varistor.
- the bimetallic bent to move the conductive element away from the connector, which has the effect of interrupting the power supply of the varistor.
- an insulating screen is interposed between the conductive element and the connector to prevent reclosing of the circuit when the bimetallic returns to its initial position after cooling.
- these devices have the disadvantage of requiring a careful design of the bimetallic strip, as well as good mounting accuracy. Indeed, of these depends the contact force applied at the electrical contact of the interruption means in normal operation which must be able to flow very large currents in case of surges on the power grid related to lightning.
- the deformation tolerance of bimetals as a function of temperature requires an individual adjustment similar to that used to adjust the sizes of modular circuit breakers.
- the slow and progressive opening of the contacts does not allow a break of a short circuit current.
- the object of the present invention is to provide a device for protection against overvoltages at least partially overcoming the aforementioned drawbacks. More particularly, the invention aims to provide such a device that is simple and reliable implementation.

- the bimetallic strip 17 is in the form of a straight strip in a state that is not deformed by heating.
- the bimetallic strip 17 is mounted at one end on a connection electrode 11a of the varistor 11.

- the possible movements of the trigger bar 15, depending on the deformation of the bimetallic strip 18, are also along the main face of the varistor 11, as indicated by the arrows F and G.
- the bimetallic strip 18 tends to open, in other words its end 18a moves downwards in FIG. 3, and thus causes the arm 18b to rotate in the direction of the arrow F.
- the displacement of the bimetallic strip 17 or 18 along the main face of the varistor 11 in the embodiments of FIGS. 2 and 3 is also advantageous from the point of view of the size of the device.
- FIG. 4 illustrates yet another embodiment of the actuating means 12 used in the device illustrated in FIGS. 5 and 6.
- the actuating means 12 comprise a bimetallic strip 19 having a parallelepipedal plate shape in an undistorted state .
- the bimetal 19 is fixed in an end region - in this case, in its upper part - on a main face of the varistor 11. More specifically, the bimetallic strip 19 is fixed on an electrode of the varistor 11 arranged on its surface main. Fixing the bimetallic strip 19 to the electrode can be carried out by any appropriate means such as by riveting holes 19a in the bimetallic strip 19.
- the bimetallic strip 19 is in thermal connection with the varistor 11 essentially by conduction between the bimetallic strip 19 and the electrode of the varistor, but also by convection and radiation. Under the effect of the temperature, the bimetallic strip 19 deforms in the part opposite to the end region by which it is fixed on the varistor 11.
- the movement generated by the bimetallic strip 19 due to its deformation, is transmitted in this case to the trigger mechanism of the switchgear 2 through a rocker mechanism. More particularly, it is a monobloc rocker mechanism.
- a portion of the rocker forms a mast 21 pivotally mounted in the housing 1a.
- the lower and upper ends of the mast 21 are housed in bearings 21a shown in Figures 5 and 6.
- the trigger bar 15 is arranged on the mast 21 and extends in a longitudinal direction substantially orthogonal to the axis of rotation 21 of the mast 21.
- the trigger bar 15 protrudes out of the casing 1a through a window thereof and enters a window 16 of the housing 2a to cooperate with the mechanism of triggering of the breaking device 2, when the protection module 1 and the breaking device 2 are assembled.
- the connection between the lower and upper ends of the mast 21 and the bearings 21a may be purely a pivot or alternatively a sliding pivot, especially if the trip mechanism of the circuit breaker requires a combined movement of the trigger bar 15 in pivoting and translation during of its actuation.
- the mast 21 further comprises a rigid pallet 22 whose extension plane containing the axis of rotation J is substantially orthogonal to the longitudinal direction of the trigger bar 15.
- the bimetallic strip 19 is for this purpose in mechanical contact and preferably in free support on the rigid pallet 22.
- the trigger bar 15 rotates about the axis J with the pivoting of the mast 21, which has the effect of operate the trigger mechanism of the switchgear 2.
- the mast 21, the trip bar 15 and the rigid pallet 22 can be made in one piece, for example by injection of a synthetic material, which provides a saving in production and assembly.
- the fact that the mast 21 rotates - because of the pivot connection or sliding pivot - is advantageous because the rotational guidance is simple to implement and particularly reliable in contrast to a guide in pure translation, particularly with respect to a piece of plastic material.
- the locking system comprises an elastic tongue 23 integral with the rigid pallet 22.
- the resilient tongue 23 is for example an extension of reduced dimensions of the lower part of the rigid pallet 22.
- the dimensions of the elastic tongue 23 are chosen to give it a suitable elasticity given the material constituting the rigid pallet 22.
- the resilient tongue 23 is attached and fixed on the rigid pallet 22 by any appropriate means.
- the locking system also comprises a fixed abutment integral with the housing having a first bearing surface 24 and a second bearing surface 25 for the resilient tongue 23.
- the latter is prestressed against the first bearing face 24 by imposing on it bending downwards when mounting the rocker in the casing la.
- Such an arrangement is shown in FIG. 5 and corresponds to a position of non-triggering of the trip bar 15, that is to say to a power supply of the protection module 1.
- the thermal energy released by the varistor 11 causes sufficient heating of the bimetal 19 to cause it to deform.
- the lower end of the bimetallic strip 19 flexes and deviates from the varistor 1 1 by lifting the rigid pallet 22.
- the bimetal 19 pushes the mast 21 according to a rotational movement to its trigger position.
- the trip bar 15 then actuates the trigger mechanism of the disconnect switch 8 in the housing 2a.
- the protection module 1 is then isolated from the power supply.
- the rotation of the mast 21, on a stroke determined by the deformation of the bimetallic strip 19, also results in a rotational movement, the elastic tongue 23, which is positioned because of its elasticity on the second bearing surface 25.
- the second bearing face 25 is preferably adjacent and substantially perpendicular to the first bearing face 24.
- This second bearing face 25 serves as an abutment to the elastic tongue 23 as illustrated in Figure 6.
- the elastic tongue 23 prevents the mast 21 from pivoting in the opposite direction to return to its initial position shown in FIG. 5. This results in an irreversible positioning of the mast 21 in its triggering position of the breaking device 2, even if after cooling the bimetallic strip 19 returned to its initial position before deformation.
- the design of the fixed abutment and the elastic tongue 23 take into account, where appropriate, the translational displacement component of the mast 21 in the case where the connection between the mast 21 and the bearings 21a is a sliding pivot intended to allow the movement bar 15 to follow a path imposed by the tripping mechanism of the circuit breaker, requiring a combined displacement in rotation and in translation of the trip bar 15.
- the irreversible positioning of the mast 21 in its release position is obtained thanks to the intrinsic restoring force of the elastic tongue 23, bringing said tongue upwards in a position abutting against the second bearing face 25.
- the trip bar 15 remains in its trigger position, the switchgear 2 can not be reset using a manual or automatic control.
- the user is then informed, at least visually, by the tripping position of the operating lever of the circuit breaker, of a poor operating state of the protection module 1.
- An unsuccessful reset attempt gives the user otherwise. sensory information and more particularly tactile, indicating that the protection module is not operational.
- thermosensitive member and more particularly the bimetallic strip 19 has a bistable deformation property, conferring on it a stable configuration that is not deformed in the absence of a heating of the varistor 11, as well as a configuration stable distorted in response to a given heating of the varistor 11.
- thermosensitive member and in particular bimetal, is advantageous because of both the accuracy of the temperature at which it is deforms and the brutal nature of its deformation as a function of temperature while the deformation of a conventional bimetallic, as well as a heat shrinkable element, is progressive and less precise, may sometimes require adjustment means to tare.
- Such a bistable bimetallic strip 19 may advantageously itself provide for the locking of the actuating means 12 in the release position when they have caused the opening of the disconnector switch 8.
- the locking system formed by the tab elastic 23 and the bearing face 25 forming a stop can be omitted in this case.
- the constituent material of the bimetallic strip 19 can be chosen so that its deformation cycle as a function of temperature exhibits a hysteresis. More precisely, the transition from the undeformed conformation to the deformed configuration takes place at a temperature greater than the ambient or normal operating temperature, preferably between 100 ° C. and 180 ° C. and particularly preferably between 135 ° C.
- the bimetallic strip 19 remains in the deformed state despite a return to ambient temperature, and therefore the bimetallic strip 19 maintains the mast 21 in the trigger position of the switchgear 2.
- the appropriate transition temperatures can be obtained by prestressing state induced by specific shaping of the bimetallic strip 19.
- thermosensitive member it is however possible to ensure the locking of the actuating means 12 other than by the hysteresis bistable character of the thermosensitive member, in particular by the locking system formed by the elastic tongue 23 and the bearing face 25 forming stop.
- a locking system having the same function can also be provided in the embodiments of Figures 2 and 3.
- a stop - not shown - retractable by pivoting or by its elasticity can be arranged in the housing la to cooperate with the trigger bar 15 or an upper end portion of the bimetallic strip 17.
- the trigger bar 15 or the end portion of the bimetallic strip 17 pushes the stop and passes beyond the stop in case of deformation of the bimetallic strip 17.

- the protection module 1 is represented in the non-tripped state, in other words when the bimetallic strip 50 has not yet caused the tripping apparatus 2 to be tripped.
- FIG. 13 is similar to FIG. , but on a smaller scale and represents the protection device in the triggered state, that is to say when the bimetallic strip 50 has triggered the breaking device 2 because of its deformation under the effect of the increase of its temperature beyond a given threshold.
- the varistor 11 is also not shown in order to make visible the mechanism transmitting the movement of the bimetallic strip 50 to the cut-off device 2.
- the actuating means 12 also comprise a mechanism for transmitting the displacement of the free end 50b of the bimetal 50 - due to its deformation under the effect of the increase of its temperature - to the triggering mechanism of the breaking device 2. But this mechanism is different from that of the embodiment of FIGS. 4 to 6. It is particularly visible in FIGS. 10, 12 and 13 whereas it is not visible in FIG. 11 because it is placed between the varistor 50 and the breaking device 2.
- This mechanism comprises a pallet 52 mounted pivotally or tilting in the housing la, which is realized in the example illustrated by the fact that the pallet 52 has two opposite arms 52b and 52c whose ends are each received in a housing formed in a respective projection 53a, 53b coming from material by molding the casing la.
- the two arms 52b and 52c therefore define a pivoting or tilting axis for the pallet 52.
- the pallet 52 comprises an arm 52a offset radially with respect to the tilting axis.
- the arm 52a is placed at the free end 50b of the bimetallic strip 50 so that the free end 50b comes to urge the arm 52a in the event of deformation of the bimetallic strip 50 as a result of the latter being heated.

- the pallet 52 is resiliently biased by a coil spring 55 placed around the arm 52b of the pallet 52 and which bears at one end on the projection 53b of the housing 1a and at its other end on the pallet 52.
- the pallet 52 also comprises a notch 52e into which the free end of a trigger arm 56 is inserted which is pivotally mounted in the casing 1a by its other end.

- the protection module 1 In normal operation, the protection module 1 is in the state shown in FIG. 12.
- the leakage current of the varistor 11 increases abnormally and causes a large heating of the varistor 11, this heating causes a temperature increase bimetallic 50 sufficient to cause its deformation, which has the effect of moving its end 50b away from the varistor 1 1.
- the end 50b bimetallic 50 then presses on the arm 52a of the pallet 52, which has the effect of pivoting or tilting around its axis of pivoting or tilting. This pivoting or tilting has the effect of disengaging the bearing lug 52d from the abutment surface 54.
- the pallet 52 Under the effect of the elastic bias to which it is subjected, namely by the spring 55 in our example, the pallet 52 is then moved along the axis of pivoting or tilting until the pallet 52 comes with a bearing edge 52f in abutment against the projection 53a of the housing la. In its movement, the pallet 52 causes the trigger 56 to pivot about its axis 57. Therefore, the trigger bar 15 is moved, which has the effect of actuating the trigger mechanism of the switching device 2. Therefore, the varistor 11 is disconnected from the power supply lines of the installation. This situation is represented in FIG. 13 in which it can be seen that the reset lever 2b of the circuit breaker is lowered, contrary to FIG. 12.
- FIGS. 15 and 16 illustrate a variant of the protection module 1 described with reference to FIGS. 10 to 14.
- the external appearance of the protection module 1 with its associated switching device 2 is identical to that illustrated in FIG. description made for the embodiment of Figures 10 to 14 is applicable to this variant, except for certain modifications of the actuating means 12 which will be described below.
- It also comprises a bimetallic strip 50 similar to that of the embodiment of FIGS. 10 to 14.
- FIG. 15 the protection module 1 is represented in the non-tripped state, that is to say when the bimetallic strip 50 has not yet caused the tripping apparatus 2 to be tripped.
- FIG. 16 is similar to FIG. , but represents the protection module 1 in the triggered state, in other words when the bimetallic strip 50 has triggered the associated switchgear device 2 due to its deformation under the effect of the increase of its temperature above beyond a given threshold.
- the varistor 11 is also not shown in order to make visible the mechanism transmitting the movement of the bimetallic strip 50 to the switching device 2.
- the varistor 11 is arranged in the box 1a in a similar manner in the embodiment of Figures 10 to 14.
- the actuating means 12 comprise a rod 58 which is articulated at one end 58b to the housing 1a.
- the rod 58 has a hook shape at its end 58b which engages in a through passage managed in a projection 59 which can come from material by molding the housing la.
- the rod is further inserted into a groove defined by two projections 60 which can also be made of material by molding the housing 1a.
- the other end of the rod 58 passes at the free end 50b of the bimetallic strip 50.
- This end of the rod 58 has a return 58a passing from the opposite side of the bimetallic strip 50.

- the pallet 52 is biased elastically in the direction of the axis defined by the arms 52b and 52c, for example by a helical spring 55 as in the case of the embodiment of FIGS. 10 to 14.
- the pallet 52 In the normal operating position, the pallet 52 is not in abutment against the projection 53a of the housing la, but against a recess 58c of the rod 58. It is therefore the rod 58 which retains in axial position the pallet 52. This situation is visible in Figure 15.
- the pallet 52 has a notch 52 which cooperates with a lever 56 carrying the trigger bar 15.
- the pallet 58 Under the effect of the elastic bias to which it is subjected, namely by the spring 55 in our example, the pallet 58 then moves laterally until the bearing surface 52f of the pallet 52 abuts against the projection 53a of the housing la. In its movement, the pallet 52 causes the trigger 56 to pivot about its axis 57. Therefore, the trigger bar 15 is moved, which has the effect of actuating the trigger mechanism of the switching device 2. Consequently, the varistor 11 is disconnected from the power supply lines of the installation. After triggering the switchgear 2 by the actuating means 12, it is not possible for a user to manually reset the switchgear with its reset lever 2b. Indeed, the trip bar 15 is held in the trigger position due to the elastic biasing of the pallet 2 against the projection 53a of the housing la.
- the bimetal has a purely thermomechanical operation.
- the bimetal is not traversed by a current to warm up - and thus does not itself ensure the routing of the electric current to the protective component, although a bimetal has an inherently conductive character - and there is also no auxiliary thermoelectric circuit bimetal specifically intended to heat the bimetal by conversion into current heat - for example current flowing through the protective component - such as turns surrounding the bimetal to heat it by Joule effect.
- the bimetal advantageously allows to ensure the direct detection by the thermal bond. It would be possible to use it also as a conductor in the electrical circuit, but this has the disadvantage of having to take into account its resistive nature which leads to the heating in addition of warming provided by the thermal connection with the protection component. In addition, it avoids undesirable current loop effects, which could lead to the generation of mechanical forces damaging to the reliability and operation of the device.
- thermoelectric circuit intended specifically for heating the bimetal by converting the current flowing through the protection component into heat.
- this has the disadvantage of being an indirect detection of temperature and is ultimately more complex and more expensive to implement.
- the design of the device is not only simplified, but detection is also particularly reliable when heating bimetallic is exclusively provided by the thermal link.
- thermosensitive member having a purely thermomechanical operation
- FIG. 7 represents a fourth embodiment of the functional part of a protection module according to the invention.
- the thermosensitive member consists of a heat-shrinkable bar 20.
- This may be made of any suitable heat-shrinkable material, which may be chosen for example from a polyolefin, a fluoropolymer such as PVC, FEP, PTFE, Kynar And PVDF, and a chlorinated polyolefin such as neoprene.
- the heat-shrinkable bar 20 is fixed by an end 20a in the housing la.
- the actuating means 12 also comprise a lever 30 pivotally mounted in the housing 1a, for example by one of its ends 30a.
- the other end of the lever 30 carries the trigger bar 15 intended to cooperate with the trigger mechanism of the switchgear 2.
- the heat-shrinkable bar 20 is connected to the lever 30 preferably by a pivot connection. Under the effect of increasing its temperature beyond a given threshold, the bar 20 retracts and thus causes a pivoting of the lever 30. As a result, the trigger bar 15 actuates the triggering mechanism. 2.
- the heat-shrinkable bar 20 advantageously provides the locking to block the actuating means 12 in the release position when they have caused the opening of the disconnector switch 8. Indeed, the bar heat-shrinkable 20 no longer returns to its original conformation in the event of cooling due to the very nature of heat-shrinkable materials.
- the heat-shrinkable bar 20 may be replaced by a heat-shrinkable element having any other suitable shape.
- thermosensitive member is a deformable capsule 40 filled with a fluid causing the deformation of the capsule according to its temperature.
- the deformation of the capsule 40 - which serves to actuate the trigger mechanism of the circuit breaker
- FIG. 8a is caused by the vaporization of the fluid, which provides a substantially bistable deformation property.
- the capsule 40 is arranged on a main face of the varistor 11.
- Figures 8a and 9a show the capsule 40 at room temperature, which corresponds to the normal operation of the device.
- the fluid contained in the capsule 40 vaporizes by reaching the latent heat of vaporization and the capsule 40 inflates accordingly, as shown in Figures 8b and 9b.
- the capsule 40 then acts on a mechanism - symbolized by the reference 41 - transmitting a movement to a trigger bar which cooperates with the trigger mechanism of the switching device 2 to actuate it.
- the mechanism 41 may for example be the rocker 15, 21, 22, 23 of Figure 4 in which case the capsule 40 and the rocker are arranged so that the capsule 40 acts on the pallet 22 in case of swelling to cause the pivoting of the mast 21.
- the mechanism 41 may be that of the embodiments of Figures 10 to 14 which includes the pallet 52 and the trigger 56 or Figures 15 and 16 including the pallet 52, the rod 58 and the trigger 56.
- the capsule 40
- the fluid in the capsule 40 is preferably a refrigerant. It is chosen according to the desired vaporization temperature. It may be a hydrofluorocarbon (HFC) chosen for example from R14, R23, R125, R134a, R152a, R227, R404A, R407C, R410A, R413A, R417A, R507, R508B, Isceon® 59, Isceon® 89, Forane® 23 or Forane® FX 80.
- HFC hydrofluorocarbon
- thermosensitive member In all the embodiments described, it is possible to also provide a thermal connection between the spark gap 13 and the thermosensitive member. It can also be a conduction bond, but it may be more simply a convection bond because of the confinement provided by the housing, or even by radiation.
- An advantage of the invention lies in the fact that the locking means prevent the reset of the breaking device 2 from being reset only in the event of failure of the varistor 1 1 and not in case of a self-tripping of the 2.
- the flow of a large fault current or a final failure of the spark gap 13 could cause activation of the circuit. 2.
- the locking means would not then oppose manipulation intended to rearm the cut-off device 2.
- the persistence of the failure in this case of the short circuit would lead to the instantaneous delivery of the switchgear 2 in its tripped state. The safety of all the protective components is thus ensured by the protection device according to the invention.
- the user has a feedback to the extent that he knows that an unlocked reset lever of the cutoff device 2, but that instantly returns to its trigger position thus preventing rearming, corresponds to a final failure of the varistor 11 and / or the spark gap 13.
- the protection device according to the invention thus makes it possible to guarantee the safety of the protection component, regardless of the failure mode of said protection component and without interrupting the service power supply.
- the protection module 1 has actuating means which also allow a particular movement return direct between the thermosensitive member and the trigger mechanism by means of a structure advantageously simple, compact and inexpensive.

- the protection module 1 and the switching device 2 have their respective housing.
- the protection module 1 and the switching device 2 can be integrated in a single housing.
- the protection module 1 has its own housing advantageously allows it to be used with commercial standard breaking devices - such as magnetic or magnetothermic circuit breakers - having their own housing 2a and without any modification.
- the protection module can be associated - preferably removably - with any model of circuit breakers of a given range to use the one having the desired electrical characteristics, for example in consideration of the breaking capacity and curves desired operation in view of the intended application.
- the protection module has its own housing or is incorporated with the switchgear in a common housing, it is advantageous for this housing to be provided for mounting and dismounting on a conventional connection or connection rail.
- thermosensitive member moves itself, because of its deformation, the mechanical member or bodies, including the trigger bar, which cooperate with the mechanism of triggering the switchgear 2 for the purpose of actuating it.
- the thermosensitive member causes due to its deformation a displacement of these mechanical members to actuate the trigger mechanism of the cut-off device 2, not by moving itself this or these mechanical members, but allowing, because of its deformation, their displacement under the effect of an elastic bias of this or these bodies against the deformable part of the thermosensitive element, as is the case in the embodiments Figures 10 to 16.
- thermosensitive member itself that moves this or these organs because it avoids having to provide means to solicit against the thermosensitive member.
- the actuating force applied by the trigger 56 on the trigger mechanism of the cut-off device 2 is not provided by the bimetallic strip. 50 or all another thermosensitive member that could be used in place of the bimetallic strip 50, but by the separate elastic biasing means constituted in the examples illustrated by the spring 55. In this way, it is sufficient for the bimetallic strip 50, or more generally for the member thermosensitive used, to be able to provide sufficient effort to release the pallet 52 of its abutment 53a or 58c.
- This force may be significantly less than the force required to actuate the trigger mechanism of the switchgear 2, which is provided by the biasing means - the spring 55 in the illustrated examples - which are designed accordingly. Therefore, the operation of the protection module 1 is more reliable and the design of the thermosensitive member is simplified, or it allows the use of types of thermosensitive organs that can not provide sufficient effort to operate them - the trigger mechanism of the switchgear 2
- the invention is further advantageous because the protection module 1 does not require any means of its own to isolate itself from the power supply, the switchgear 2 alone providing the electrical insulation of the protection components whatever the failure.
- the invention is also advantageous because it uses a switchgear which in itself has one or more electrical contacts used to cut the electrical circuit in which the device is inserted, and whose contact force, as well as the force applied to them to open them is determined by a mechanism specific to the cut-off apparatus.
- the contact force and the opening force of the contacts are therefore independent of the elements outside the breaking device used for its actuation.
- the contact force and the opening force of the contacts are not dependent on the effort that the thermosensitive member can provide, unlike, for example, bimetallic strip in the devices described in WO 2004/064213.
- the invention allows a reliable use of security with a reduced number of components, a simple and compact construction, quick and easy assembly and disassembly on a connection or connection rail, a control easy operation of the operating state with a visual and sensory feedback on its operating state, and this without causing unavailability of the power supply network in the event of failure of the protective device
