Definitions
- the present invention relates to devices for prohibiting power supply when necessary in installations using high intensity currents, and particularly relates to a disconnecting device of a high current current power supply line.
- the vast majority of disconnecting devices currently used consist of knife disconnectors.
- the rotary knives around an axis actuated by a suitable mechanism, provide the electrical connection pressing pressure on current input contacts.
- the sectioning thus consists of separating the knives from the fixed contacts by rotating them around their axis by means of the actuating mechanism.
- the main object of the present invention is therefore to provide a disconnecting device for high intensity power supplies which has a maximum conductance.
- Another object of the invention is to provide a sectioning device as mentioned above which comprises effective means for dissipating the heat produced by Joule effect in the device.
- Yet another object of the invention is to provide a sectioning device as mentioned above which is easily adaptable to the intensity value.
- a first object of the invention is a sectioning module of a DC power supply line of an intensity greater than 1000 A comprising:
- a sealed contact enclosure comprising at least a first fixed contact conductive element for establishing the electrical connection with a current input and a second fixed contact conductive element for establishing the electrical connection with an output of the current, the fixed contact elements being electrically connected to the outside of the enclosure respectively by two connection pads, and at least one movable contact conductive element adapted to come into contact simultaneously on the first and second stationary contact elements under the action of an actuating mechanism which is actuated for removing the contact between the fixed contact elements and the movable contact element for the purpose of cutting the supply line,
- At least one first metallic connection bar adapted to be connected to a current input and at least one second connection bar adapted to be connected to a current output, and
- first intermediate conductive element connected on the one hand to the first connection bar and on the other hand to the first fixed conductive element and a second intermediate conductive element connected on the one hand to the second connection bar and on the other hand to the second fixed conductive element.
- the module is characterized in that the power supply line provides a current of an intensity greater than 1000 A, and at least one of the fixed contact elements or one of the movable contact elements comprises a silver pellet placed on the surface of the element to reduce by half the contact resistance between the movable contact element and the fixed contact element.
- a second object of the invention is such a sectioning module used as presentation model allowing the future user to know the temperature behavior of a desired sectioning device.
- a third object of the invention is a sectioning device composed of several sectioning modules as defined above arranged in parallel so as to adapt the device to the value of the intensity supplied by the power supply line.
- FIG. 1 shows schematically a contact enclosure used in a sectioning module according to the invention
- FIG. 2 represents a particular embodiment of a fixed contact element of the enclosure
- Figure 3 schematically a sectioning module according to the invention which can be used as a presentation model
- FIG. 4 diagrammatically represents a sectioning device according to the invention comprising a plurality of sectioning modules illustrated in FIG. 3,
- FIGS. 5 and 6 show alternative embodiments of the sectioning module in which the connecting bars are connected to the contact enclosure by a layer of foam consisting of a skeleton of metal foam such as iron, cobalt, nickel and their alloys coated with a coating of tin, indium or one of their alloys (ECOCONTACT).
- a layer of foam consisting of a skeleton of metal foam such as iron, cobalt, nickel and their alloys coated with a coating of tin, indium or one of their alloys (ECOCONTACT).
- the sectioning device consists essentially of one or more sectioning modules.
- Each of the modules is adapted to allow the passage of a current of an intensity of about 3000 A. Note that the current is mainly a direct current but that it could be an alternating current and that the intensity could be different.
- the contact enclosure 10 of each sectioning module shown in FIG. 1 preferably has a rectangular shape with a length of about 40 cm and a width of about 30 cm.
- the speaker 10 is composed at least one contact bridge.
- Each contact bridge comprises two fixed contact elements 12 and 14, preferably made of aluminum, fixed by welding to 2 connection pads, preferably aluminum, respectively the areas 16 and 18 which constitute the input and the output of the current. the speaker respectively connected to the input and the current output outside the enclosure as will be seen later.
- Each contact bridge of the enclosure 10 comprises a movable contact element 20, preferably aluminum which is not in contact with the 2 fixed contact elements 12 and 14 when the sectioning has been operated for the conduct of a maintenance operation of the installation comprising the disconnecting device according to the invention.
- the contact between the fixed contact elements 12 and 14 and the movable contact element 20 is effected by a downward movement of the element 20 by means of the rods 22 and 24 actuated by an actuating means 26.
- the top of the rods 22 and 24 is locked on the movable contact element 20 by two springs 28 and 30.
- the latter comes into contact with the contact elements 12 and 14 and a pressure is exerted through the compression of the springs 28 and 30.
- An important feature of the invention is to obtain a disconnecting device which has the lowest resistance possible so as to obtain a heat dissipation Joule effect as little as possible and therefore a temperature rise as small as possible.
- a first way to obtain this result is to fix, preferably by high temperature brazing, silver pellets 32 and 34, for example of circular shape, on the contact surface of the movable contact element 20 which comes into contact with the fixed contact elements 12 and 14.
- the fixed and movable contact elements being aluminum, the contact resistance between the fixed contact element and the movable contact element would be relatively important. With the presence of silver pellets 32 and 34 whose conductivity is high, this resistance is reduced by half or, in other words, the conductance is doubled.
- the movable contact element 36 comprises silver pellets 46 and 48 for decreasing the contact resistance with the fixed contact elements 12 and 14.
- the contact chamber that has just been described has, for each of the movable contact elements 20 and 36, a resistance of about 10 ⁇ , which corresponds to a power of about 90 for a current of intensity equal to about 3,000 A.
- each of the fixed conductive elements 12 and 14 can be produced as illustrated on FIG. figure 2.
- the fixed contact conductive element 14 which is attached to the connection pad 18, comprises a lower layer 50, an upper layer 52 and an intermediate layer 54.
- the lower layer 50 is made of aluminum.
- the upper layer 52 is interchangeable and is fixed to the lower layer by a bolt 56.
- the upper layer 52 is preferably made of copper so as to deposit a coating of silver by electrolysis on its upper surface, which would not be possible if this layer was aluminum like the lower layer.
- the electrical connection between the mobile element 20 and the fixed element 14 is made by direct contact between the silver chip 34 and the silver coating of the upper layer 52, which reduces the contact resistance. A half.
- the intermediate layer sandwiched between the lower layer 50 and the upper layer 52 by the bolt 56 is preferably an ECOOCONTACT foam layer (trade mark) consisting of a metal foam skeleton selected from the group consisting of iron, cobalt, nickel and their alloys coated with at least one coating of tin, indium or one of their alloys described in French patent 1002988. Due to the cellular structure of this layer, its surface comprises a multitude of contact points. these points, the intermediate layer 54 has many contacts with the lower and upper layers, which allows to obtain a high conductivity and therefore a low resistance. It is found that, as previously with the silver pellets, the resistance between the fixed contact element and the movable contact element is halved.
- the fixed contact conductive element 12 connected to the connection pad 16 also comprises, in its upper part, a structure identical to the three-layer structure illustrated in FIG. 2.
- an identical three-layer structure, symmetrical to that illustrated in FIG. 2 is also located at the lower portions of each of the fixed contact elements 12 and 14.
- the three-layer structure illustrated in Figure 2 can be used for either side to the lower portions of the fixed contact member 20 comes into contact with the fixed contact members 12 and 14, but also instead of the silver pellet 32, 34.
- the contact enclosure which has just been described is waterproof, it can still occur dust deposits on the elements it contains. Such deposits, for example on the silver pellets, lead to a degradation of the contacts which results in an increase of the electrical resistance. In addition, when cutting, there may be an electric arc caused by a residual intensity due to battery power.
- a preferred embodiment consists in filling the enclosure with a perfect seal of an inert gas instead of air.
- a gas may be a neutral gas such as helium or neon, or else nitrogen, and preferably sulfur hexafluoride (SF6).
- Another way of reducing the temperature produced by the heat dissipation is to provide a circulation of a coolant, for example water, in a manifold (not shown) located within each of the connection pads. and 18.
- a coolant for example water
- the sectioning module according to the invention can be produced as illustrated in FIG. 3.
- Such a module comprises an enclosure 10 described above electrically connected to the input and the current output thanks to the contact pads 16 and 18.
- the current input and output (not shown) are connected to the module by two connection bars 60 and 62 for the current input and by two bars 64 and 66 for the current output.
- the connecting bars 60 and 62 are connected to the enclosure 10 by a plurality of connection blades divided into two groups of blades 68 and 70.
- an important feature of the invention is to limit as much as possible the temperature rise due to heat dissipation due to the Joule effect.
- the structure in a plurality of blades has a very large area with air composed by the two faces of each blade multiplied by the total number of blades.
- the blades form a Z so that they have the greatest flexibility and can be deformed in both angles of the Z under the effect of temperature.
- the sectioning module which has just been described with reference to FIGS. 1, 2 and 3 has a rectangular shape whose largest dimension is between 0.90 m and 1.20 m and the smallest dimension between 0.40 m and 0.60 m, and has a thickness of about 3 cm. Its weight is between 20 and 30 kg.
- this module can pass a current whose intensity is about 3000 A.
- the disconnecting device comprises a plurality such parallel sectioning modules.
- An important object of the invention is to use the sectioning module described above as a presentation model. Indeed, the size and weight of a module being relatively low, it is easy for the manufacturer to transport only the module to present it to any potential customer or future user. This The latter will thus be able, by using a current of reduced intensity, to quickly define how many modules will be needed in the desired sectioning device and to know the temperature behavior of said sectioning device.
- a sectioning device comprises a plurality of modules which are assembled in parallel to correspond to the intensity of the current to be cut.
- the current has an intensity of 20 kA, it is necessary to provide eight modules of sectioning in parallel.
- the resulting disconnecting device then comprises a single connection pad, preferably made of aluminum, for the electrical connection to the outside of all the modules.
- FIG. 4 represents a disconnection device used for an intensity of approximately 120 kA composed of six partial disconnecting devices composed of two sets of three subassemblies 80, 82 and 84 of eight modules each, such as the subassembly 80.
- each module, illustrated in Figure 3 of each of the three subsets is in front of a module which is symmetrical and which belongs to a subset of the other set.
- the modules of the subassembly 84 are symmetrical modules of the subset 86.
- the three subassemblies or partial disconnecting devices 80, 82 and 84 have a common actuating mechanism 88.
- This mechanism is for example a mechanism for rotating a shaft which, by means of a set of connecting rods, causes the compression of the springs described with reference to FIG. 1 and allows the contacts inside the enclosure for the passage of the current.
- connection structure 80, 82 and 84 which in FIG. connection, is connected to the current input by two connecting rods 92 and 94 and through two sets of connecting blades 96 and 98.
- the same structure (not referenced) as that which has just been described is symmetrical with the latter and includes all the symmetrical partial disconnecting devices of partial disconnecting devices 80, 82 and 84.
- the sets of connecting blades for dissipating the heat produced by Joule effect are replaced by the devices illustrated in FIGS. 5 and 6.
- connection bar is fixed directly to the connection pad 16 (or 18) by bolts 102.
- a layer 104 of foam ECOCONTACT (registered trademark) consisting of a metal foam skeleton selected from the group consisting of iron, cobalt, nickel and their alloys coated with at least one coating of tin, indium or an alloy thereof.
- the surface of the layer has a multitude of contact points With these points, the layer 104 has many contacts with the connection bar 100 on the one hand and with the connection pad 16 on the other hand, which makes it possible to obtain a high conductivity and therefore a low resistance.
- the connecting bar 106 is connected to the connection pad 16 by means of an intermediate bar 110 to which it is soldered.
- the intermediate bar 110 is fixed to the connection pad 16 by means of bolts 112 and 114.
- an ECOCONTACT foam layer as in the embodiment of FIG. 5.
