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 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 the terminal 101.
  • 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 means device 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 20 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.

  • 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.
