Definitions
- the present invention relates to protective devices electrical installations against supply disturbances.
- Protection devices (which will be designated in this text by DAF designation “lightning protection device”) can be integrated into a switchboard controlling the supply of several electrical outlets, or be connected directly upstream of the device to be protected.
- Existing DAFs whether of the monobloc or modular type, use means for connecting the pins of the elements of connectors (themselves in contact with the supply circuit and the circuit to be protected) to the active part of the DAF.
- These means generally comprise a conductive part of connection, connected to a first pin of the connector elements and welded to a first terminal of the active part, the other terminal of which is directly connected to the second pin of the connector elements.
- the weld between the connecting piece and the first terminal of the active part thus ensures mechanical contact between these two elements, and consequently the closing of the circuit of electrical protection formed by the connection elements and the part active DAF.
- the welding is carried out so that when the current flowing through the DAF exceeds predefined values and characteristics of the DAF, or when the active part which is nearby of the solder causes excessive heating when reaching the end of its life, the connection provided by said weld is undone (by rupture or fusion of the welding) to allow the two elements it connects to separate.
- the connecting piece is generally subjected to a permanent mechanical stress, tending to separate it from the terminal of the active part to which it is welded.
- the permanent mechanical stress mentioned above may result elastic deformation before welding of the conductive part, as describes it for example the document EP 0 716 493 in the name of the Applicant.
- Figure 1 is a diagram showing the main subsets a DAF according to the state of the art.
- the DAF of this scheme is modular, but its subsets significant with regard to the invention which will be described may also be integrated into a known type of one-piece DAF.
- the modular DAF 10 is shown, composed of a cartridge 100 which can be plugged into a base 150.
- the cartridge 100 includes a surge protection circuit 40 which can be of any known type using for example varistors.
- the circuit 40 is connected to two terminals 101 and 102 each placed on one side side of the cartridge.
- the cartridge of this modular DAF also includes two pads 103 and 104 for plugging into two respective female connectors 151 and 152 of the base 150.
- the terminal 102 is directly connected to the pad 104 by a link 1020, while terminal 101 on the opposite side of the cartridge is connected to a first rigid and electrically conductive part 110.
- the stud 103 is connected to a first end of a flexible braid 105 also conducting electricity, the other end of which is connected to a second rigid part or cursor 120.
- the cursor 120 is connected to the part rigid 110 by a conductive weld 130.
- Solder 130 is a low temperature solder which melts under the effect of prolonged exposure to a temperature exceeding approximately 100 ° C. This weld has a double holding function mechanical slider 120 in contact with the rigid part 110, and current routing between the braid 105 and the terminal 101.
- solder 130 by a non-conductive hot-melt element having a adhesive function (which can be produced for example in wax) ensuring the mechanical holding function and melting under the same conditions thermal, associated with an electrically conductive element capable of ensuring a link between the part 110 and the cursor 120 as long as the element hot melt is in place, this electrically conductive connecting element being however automatically broken when the element is merged hot melt.
- This electrically conductive connecting element can be formed of one or more thin, electrically conductive embedded wires in the hot-melt element. The mechanical role of these wires is negligible, but said wires provide the electrical connection between the braid and terminal 10.
- the electrically conductive connecting element can also be consisting of conductive means external to the hot-melt element.
- a spring 140 permanently requests the cursor 120 for the detach from the part 110.
- the spring is compressed between a fixed support (which here is integral with the base but can press on an integral part of the cartridge), and the cursor.
- the spring can also be placed in any other conventional configuration, and in particular exert a traction on the end of the cursor opposite to the base 150.
- the base 150 comprises two pins 153 and 154 connected to the connectors 151 and 152 respectively. These two pins allow connect the supply circuit to the circuit to be protected via the base, which is intended to be permanently fixed to an electrical panel.
- a device of this type has a limited lifespan. Arriving at the end of life its components heat up, causing the fusion of the weld 130. The cursor then no longer linked to the cartridge 100 is pushed towards the up by the spring and moves to stop the supply of the line to be protected by opening the protection circuit, as well as visualization and possibly the command of the remote signaling of the state of said varistor.
- the weld 130 can also be broken by a shock caused by the passage of an excessive current, which causes the same displacement cursor.
- Modular surge arresters such as that described with reference to the Figure 1 only offer a binary display of the state of the active part, ie that said part is in working order or that it has reached its end of life.
- a drawback of DAFs of the type described with reference to the figure 1, whether modular or monobloc, is that the presence of the braid complicates the mounting of the device, requiring points of additional soldering or crimping which tend to weaken overall, and to increase the risk of breakdown.
- An object of the present invention is to make it possible to perform DAFs simple and reliable structure, not including a braid which would constitute a bulky and weakening element.
- a second object of the invention is to make it possible to develop a DAF withdrawable according to the characteristic stated in the previous paragraph, in which the cartridge is capable of flowing a current to the ground intensity of the order of 65 kA 8/20, the geometry of the cartridge respecting standard dimensions requiring in particular a height of 58 mm.
- the invention provides a protection device against overvoltages of electrical devices to which the device is connected via connection means comprising at least two connectors, the device also comprising a lightning protection cell including a first pole is directly connected to a first of said connectors, characterized in that that a second pole of the cell is connected to a first part conductive, in that the device also comprises a second part conductive directly connected to a second of said connectors and in that that the device also includes fusible link means for maintain a rigid cursor in electrical contact with said parts conductive in an operating position of the device, means being adapted to permanently urge the cursor to a position opening of the device in which said cursor is no longer in contact with the two conductive parts.
- FIG. 2a the principle of the structure has been represented. internal of a DAF according to the invention.
- the device shown in this figure is of modular type, but the principle of the invention is also applicable to monoblock DAFs.
- the withdrawable cartridge of the DAF comprises an active part 40, connected via two terminals to pads 22 and 23 for plugging into a base such than that described with reference to Figure 1.
- the pad 22 is directly connected to a first conductive part rigid 24, which is located opposite a second rigid conductive part 26 fixed on a first terminal 260 of the active part.
- the two rooms 24 and 26 are fixed, and separated by a space sufficient to prevent passage current between them when said space is cleared.
- the pad 22 and the conductive part 24 can also constitute a unique element.
- a third rigid part 27, or slider is mounted in translation of so as to be able to be engaged in the space separating parts 24 and 26 in a first position in which the cursor establishes a contact electric between the two rooms when said space is free.
- a weld 25, of the type described with reference to FIG. 1, keeps the cursor in said first position and thus links electrically the pads 22 and 23, the second terminal of the active part which is not shown in the figure being directly connected to the stud 23.
- solder 25 can be replaced by a hot melt connection equivalent mechanical characteristics. In this case, it is not necessary to provide additional means to establish contact electric between parts 24 and 26, said contact being ensured by the cursor 27 in its first position.
- the spring 28 can also be compressed between a fixed point 280 of the cartridge and a part 281 secured to the cursor.
- the effect of the spring is the even on the cursor.
- This arrangement is advantageous because it makes it possible to carry out a DAF or a DAF cartridge with a smaller footprint or, equivalent footprint, to integrate additional components, as we will see.
- a cartridge 30 of DAF modular, standard format which can contain according to the state of the art a single varistor, carries on its lower face 301 four studs 22a, 22b, 23a and 23b for plugging into a fixed socket.
- the cartridge 30 according to the invention does not include a braid such that described with reference to Figure 1. This results in space saving which allows to house in the housing 300 of the cartridge two varistors intended for be connected in parallel between the phase wire on the one hand, and on the other hand the neutral or earth of an electrical installation, or between neutral and earth.
- Cartridge 30 includes also two pins 36a and 36b whose role will be explained later in this text, protruding out of the face 301 which is intended to be in contact with the base, the two pins being able to slide in the openings 360a and 360b of said face 301 of the housing 300 for a retraction in the housing.
- FIG. 4 is a perspective view of the cartridge 30 and the corresponding base 400, which includes the coding 350.
- Figure 4 also shows a variant of the invention, which consists in providing the base with a socket for the connection of a 410 module remote indication of the cartridge status. We will come back to the means to control this remote signaling.
- FIG. 5a to 5d show the four possible states of the two varistors, referenced here 40a and 40b. These two varistors, which are mounted as we said in parallel, are each associated individually to the disconnectors 25a and 25b, respectively.
- the disconnectors 25a and 25b are produced by the combination of the cursor 27 and a fuse link such as the solder 25 of FIG. 2.
- the housing generally paralepipedic 300 of the cartridge 30 contains two subsets identical, one of which will be described here.
- the varistor 40a which is located in the central part of the case, is connected by a first terminal to stud 23a for connection with a base, and by a second terminal 400a to a fuse link 25a which implements a weld as described above.
- the welding of the link 25a maintains a cursor 27a leading electricity in contact with terminal 400a and connection pad 22a with a base, said cursor thus ensuring contact with the weld connection between the terminal and the stud.
- a spring 28a is prestressed in compression, its lower end being linked to the cursor 27a above which the spring is located, and the other end of the spring pressing against a finger 60a secured to the cursor, finger that the spring tends to move away from the face 301 of the cartridge.
- the pin 36a, the link 25a, the terminal 400a and the spring 28a are arranged along a lateral face of the housing adjacent to the face 301.
- a direction I is defined with reference to this figure perpendicular to this lateral face.
- the spring exerts a thrust constant, direction parallel to said lateral face of the housing and directed towards the face of the case opposite the base, on the finger 60a which urges its turn the cursor 27a aligned with the pin 36a and the spring 28a.
- the spring 28a separates the cursor 27a from the solder 25a and drives the finger 60a rigidly secured to the cursor and aligned above it, towards the upper face of the housing which is opposite to the base.
- FIGS. 7a to 7c are diagrams of views in the direction I of FIG. 6, elements of the cartridge 30 in the three possible states of device according to the invention.
- the face that the housing 300 presents in these views is that, lateral, against which the assemblies formed by a spike, a fusible link, a cursor, a spring and a finger secured to the cursor are installed.
- Figures 7d to 7f are three schematic views of the witness 600 seen from the interior of the case 300, corresponding to the states of views 7a to 7c respectively.
- the two identical and parallel fingers 60a and 60b, respectively attached to the sliders linked to the two varistors of the DAF, are at a distance from witness 600, the two links 25a and 25b being provided by the welds of the respective sliders.
- Figure 7a shows the U-shaped section of control 600 which shows one side parallel to the wall of the housing located nearby and two lateral sections 600a and 600b located on the sides of this first face and protruding towards the inside of the housing 300.
- the ends of the two fingers 60a and 60b which are turned towards the witness 600 define a beveled profile with two oblique ramps and opposite to the axis of the finger.
- the ends of the fingers 60a and 60b each defines a protruding V-shaped profile, the two slopes of each V being able to cooperate with the protruding sections of the witness 600 as we will explain.
- the width of the witness defined by the distance between its two sections lateral 600a and 600b, is chosen less than the value of the center distance between the two fingers 60a and 60b.
- the corresponding view 7d shows that the indicator 600, which is mounted at pivoting about an axis 620 which extends substantially parallel to the fingers 60a and 60b, is then in the middle of the face 302 of the case close to which it is implanted. An outside observer looking at this face 302 of the case 300 can then see through a window 610 of said face the position of the witness which completely obstructs orifice 610.
- witness 600 has an extended central portion 6000 extended by a second portion 6001, made of material with the portion 6000, located in its extension and of substantially smaller width.
- the indicator 600 also has two elastic lateral tabs 602a and 602b intended to come selectively to bear on the side walls of the case to stabilize the position of the witness, as we will explain.
- the finger 60b has been moved by the spring which is linked to it following the rupture or the fusion of the corresponding weld.
- the ramp of this finger which is turned towards finger 60a then cooperates with the projecting section 600b of witness 600 to move one end of said witness, which rotates then around axis 620, as shown in Figure 7e.
- the witness In the position of FIG. 7e, the witness is kept in a angular position away from the median axis of the face 302 of the cartridge, on the one hand thanks to the cooperation of the finger 60b with the section 600b, and on the other hand to the elastic support on an internal side wall of the housing 300 of the lateral tab 602b of the witness, elastically deformable.
- witness 600 which is not constant width but has two symmetrical lateral recesses defining a narrower width near its end being in the region of window 610, an outside observer can view the state of the device. Indeed, in this position of the witness 600, the window 610 is only partially obstructed by witness 600 due to its position angular away from the median axis of the face 302.
- the ramp of the finger 60a remote from the finger 60b cooperates with a second projecting section 600a of the witness to further move said witness rotating in the same direction as before.
- An outside observer then visualizes through window 610 the state of the cartridge, the indicator 600 leaving the window completely cleared.
- a user can therefore view the status of the cartridge at any time DAF according to the invention.
- the two sections protruding 600a and 600b of the witness extend respectively opposite symmetrical inclined ramps of the two fingers 60a and 60b, and that the witness 600 is itself symmetrical, the operation of the device is the same regardless of the varistor arriving first at the end of life.
- the device according to the invention is particularly advantageous in that that it has characteristics of reliability and robustness due to the absence of a braid, the bonds of which are a factor of fragility.
- the device according to the invention allows, as has been shown to integrate into a withdrawable DAF cartridge of reduced format two varistors operating according to a reserve system.
- the means of contact of the base with the cartridge can include semi-rigid means conducting electricity, the section of which is in the shape of a "U" so as to define two branches placed opposite between a connector on the base and a connector on the cartridge, each branch being in contact with a respective connector.
- This characteristic generates in said contact means a electrodynamic force tending to spread their branches, when the means contacts are crossed by a current. Said branches go under the action of this spreading force press against the connectors the base and the cartridge, ensuring the quality of the contact between these connectors.
- cartridge sub-assemblies included a solder 25a connecting terminal 400a to a stud 22a.
- This welding also makes it possible to maintain the cursor 27a in a space located between the terminal 400a and the stud 22a, so as to ensure the electrical contact between these two elements.
- varistor 40a is also associated the picot 36a projecting from the so-called lower face 301, through an opening in which it can slide longitudinally in a direction perpendicular to the plane of the face 301.
- the subassembly also includes the spring 28a located at the inside of the case and substantially aligned with the pin 36a and the cursor 27a. It will be noted here that the spring 28a can also be prestressed in extension between a fixed point on the housing away from the base and the cursor, and act on it in the same way as described above.
- the pin 36a is also integral with the cursor 27a so that when said cursor is held between terminal 400a and stud 22a by the solder 25a, the pin 36a protrudes from the face 301 of the housing in protruding from said face by a height H1.
- the pin 36a, the slider 27a and its weld 25a as well as the spring 28a are arranged to be substantially aligned along the same face of the cartridge case 30.
- the spring 28a recalls the cursor and the pin towards the side of the cartridge opposite to the base, said pin then being retracted (partially or completely) in the cartridge.
- the cartridge 30 also includes a second sub-assembly identical to the one just described, implementing a second spring, a second slider and a second pin 36b.
- the welds respectively associated with the two varistors maintain the two pins 36a and 36b projecting from a height H1 outside the cartridge case.
- FIG 8 there is shown in section transverse vertical the cartridge 30 plugged into the base 400, the studs 22, 23 of connection not being shown on this sectional plane which contains the axes of the two pins 36a and 36b.
- the base includes a part 29 comprising a plate rectangular 290 extending substantially parallel to the upper face of the base and a half-disc 291 perpendicular to the plate, one of which side forms an edge 292 with the diameter of the half-disc.
- the half-disc 291 which is located in a housing complementary to the base, can pivot while remaining in the same plane, as well as move in translation towards the upper face of the base.
- the pins 36a and 36b are shown projecting outside the cartridge. In this position, the two pins enter the base by the respective orifices 46a and 46b and are supported on the upper face of the plate 290, on either side of the axis of symmetry of the part 29 which is perpendicular to the edge of the part.
- the center of the underside of the plate is also pressing a 295 microswitch button controlling the signal reversal all or nothing of a remote signaling circuit of the state of the device.
- the three support points on the two sides of the plate are aligned parallel to the edge of the part, creating no moment perpendicular to this edge on the part 29.
- a spring not shown in the figure tends to lift in permanently push button 295.
- the plate has a pressure transmission function pimples to the pusher and presses itself on the top of the pusher, now this one in a so-called low position corresponding to the remote signaling of a device state in which the two varistors are operational.
- the pusher 295 can then be lifted under the action of the spring which permanently requests it, up to a second so-called high position where said pushbutton controls the reversal of electrical signals to signal the fault varistor.
- Figures 9a to 9c schematically represent the positions possible of the pair of pins 36a and 36b of the part 29 and of the pusher 295 controlling the remote signaling signals of the state of the device.
- the two pins 36a and 36b project towards the bottom out of the cartridge, the two varistors associated respectively with these pins being in service.
- the wafer 290 is maintained as we saw it perpendicular to the axes of the pins and the pusher 295 by the equal and diametrically opposite pressures of these two pins, and the said pusher is held down in said low position.
- This low position of the pusher corresponds to the control of electrical signals remotely indicating that the two varistors of the device are in service.
- one of the two pins is retracted inside the cartridge case.
- it is the pin 36b which is retracted.
- the configuration described here is symmetrical and could apply to a situation in which the pin 36a is retracted and the pin 36b is projecting downwards.
- the wafer 290 has, as we have seen pivoted around its point of contact with the pin 36a, and the pusher 295 is in the high position due to the stress of the spring associated with it.
- the pusher In this high position, the pusher signals at a distance that one at least one of the device's two varistors is out of service.
- FIG. 9c the two pins 36a and 36b are retracted.
- the wafer 290 thus finds a position parallel to its position in the figure 9a.
- the push-button 295 remains in this configuration in the high position and thus always signals the device fault remotely.
- the microswitch when inserting a cartridge, the two of which varistors are in service in the base, the microswitch changes state in moving from its high position to its low position (indeed, part 290 is translated from its position illustrated in FIG. 9c to its position illustrated in the Figure 9a when installing a cartridge).
- Such use of a single microswitch to report the condition of a device with two varistors makes it possible to reduce the complexity and the costs linked to the wiring between the microswitches and a remote signaling unit, compared to existing solutions in which a microswitch is associated with each varistor.
