Definitions
- the present invention relates to the general technical field of equipment protection devices or electrical installations against overvoltages, including transient overvoltages due to lightning, overloads or short circuits.
- the present invention more particularly relates to a protection device of an electrical installation against overvoltages, overloads or short circuits comprising at least two main electrodes between which an electric arc is likely to form, as well as a device for breaking of the electric arc, formed by an assembly of splitter plates and extending, in consideration of the direction of propagation of the electric arc, between an upstream end and a downstream end and having, at its upstream end, a zone d the entrance of the arc, at which the electric arc penetrates inside the cut-off device, said cut-off device comprising, arranged at its upstream end, non-return means of the electric arc, structurally designed and arranged to allow entry of the electric arc into the cut-off device while forming an obstacle to the exit e of the electric arc, so as to prevent the electric arc, once located inside the cut-off device, from escaping from the latter.
- Such protection devices are generally equipped with a device for breaking the current (or interrupting chamber).
- this breaking device is intended to ensure the breaking of short-circuit currents.
- the breaking device is intended to ensure the extinguishing of currents.
- the cut-off device is generally formed by a plurality of metal splitter plates mounted in parallel so as to break down the electric arc into small elementary arcs in order to increase the arc voltage and to cut off the current.
- Known cut-off devices intrinsically have a predetermined breaking capacity corresponding to the maximum value of the current they are likely to extinguish.
- the electric arc can, after having entered the cut-off device, escape from the latter and be reformed. outside, for example by using the shortest path between one of the main electrodes and the end of the splitter plates.
- Such a phenomenon is particularly harmful to the protective device insofar as it has the effect of interrupting the attempt to cut the current.
- this phenomenon can occur several times during a short time interval. The electric arc can thus enter the cut-off device, exit and re-enter it, until the device is destroyed without being able to interrupt the current or short circuit.
- the objects assigned to the invention therefore aim to remedy the various disadvantages listed above and to propose a new device for protecting an electrical installation against overvoltages, overloads or short circuits whose breaking capacity of the current is improved.
- Another object of the invention is to provide a new device for protecting an electrical installation against overvoltages, overloads or short circuits whose size is limited.
- Another object of the invention is to provide a new device for protecting an electrical installation against overvoltages, overloads or short-circuits whose structure is particularly adapted to the case currents of high intensity.
- Another object of the invention is to provide a new device for protecting an electrical installation against overvoltages, overloads or short circuits whose manufacture is particularly simple.
- the objects assigned to the invention are achieved by means of a device for protecting an electrical installation against overvoltages, overloads or short-circuits comprising at least two main electrodes between which an electric arc is likely to occur.
- a device for breaking the electric arc formed by an assembly of splitter plates and extending, in consideration of the direction of propagation of the electric arc, between an upstream end and a downstream end and having at its upstream end, an arc entry zone, at which the electric arc penetrates inside the cut-off device, said cut-off device comprising, disposed at its upstream end, insulating means -return of the electric arc, structurally designed and arranged to allow the entry of the electric arc into the cut-off device while forming an obstacle against the an output of the electric arc, so as to prevent the electric arc, once located inside the cut-off device, from escaping from the latter, characterized in that the insulating means are formed by caps arranged to form a partial insulating barrier between the electrodes and the upstream

- FIG. 3 illustrates, in a front view, the cut-off device illustrated in FIG. 2.
- FIG. 4 illustrates, in a view from above, the cut-off device illustrated in FIG. 2.
- FIG. 5 illustrates, in a front view, another embodiment of a cut-off device for the protection device according to the invention.
- FIG. 6 illustrates, in a side view, another embodiment of a cut-off device for the protection device according to the invention.
- FIG. 7 illustrates, in a side view, another embodiment of a cut-off device for the protection device according to the invention.
- the protective device of an electrical installation against overvoltages, overloads or short circuits is intended to protect equipment or an electrical installation.
- Electrical installation refers to any type of device or network that is susceptible to voltage disturbances, including transient overvoltages due to lightning or overloads, such as overload or short-circuit currents.
- Such devices may thus consist of surge arresters or surge arresters provided with a current cut-off device or circuit breakers provided with a device for breaking the short-circuit current.
- FIG. 1 illustrates a protection device 1 according to the invention advantageously formed by a spark gap arrester.
- the protective device 1 comprises, advantageously mounted within an insulating housing 20, at least a first and a second electrode 2, 3 which can form, as illustrated in FIG. 1, the two main electrodes of the spark gap arrester .
- These two electrodes 2, 3 are kept at a distance from each other and separated by a strip 4 of dielectric material which improves and better control the initiation of an electric arc 5 between the electrodes 2, 3 This so-called upstream part of the device thus constitutes the zone of initiation of the electric arc 5.
- the electrodes are formed by two contacts, for example a fixed contact and a movable contact held in physical contact with each other to ensure the electrical connection.
- the electric arc is formed between the two contacts when the movable contact deviates from the fixed contact to ensure the electrical disconnection.
- the protection device 1 comprises a device 6 for breaking the electric arc 5.
- the cut-off device 6 is formed by an assembly of splitter plates 7 made of electrically conductive material, for example made of metal, arranged in parallel and at a distance from one another.
- the fractionation plates 7 are advantageously kept at a distance from one another by means of holding blades 8 made of electrically insulating material.
- the cut-off device 6 extends, in consideration of the propagation direction F of the electric arc 5, between an upstream end 6A and a downstream end 6B. As illustrated in FIGS. 3 to 5, the cut-off device 6 has, at its upstream end 6A, an input zone E of the electric arc, at which the electric arc 5 enters the 6. Thus, before entering the cut-off device 6, the electric arc 5 propagates along the direction of propagation F, within a diverging space 9 extending between the priming zone. of the electric arc and the cutoff device 6.
- the diverging space 9 is advantageously delimited by the electrodes 2, 3 and preferably filled with air.
- the cut-off device 6 comprises, at its upstream end 6A, insulating means 10 against the return of the electric arc 5.
- These insulating means 10 are structurally designed and arranged in such a way as to allow the entry of the electric arc 5 into the cut-off device 6 while forming an obstacle against the output of the electric arc 5 so as to prevent the arc once inside the cut-off device 6 escapes from the latter.
- the insulating means 6 are thus adapted to prevent the electric arc 5 from going back, in a direction opposite to its normal direction of propagation F, so that when decomposed into a plurality of elementary arcs within the device 6, the electric arc 5 can not more to reform on the outside of the cut-off device 6, in particular in the diverging space 9.
- the non-return insulating means therefore operate in the manner of a trap, and are constructed and arranged relative to the fractionation plates 7 on the one hand and to the electrodes 2, 3 on the other hand, so as to substantially reduce the probability that the electric arc 5 does not escape the cut-off device 6.
- the design of the protection device 1 according to the invention therefore makes it possible to significantly improve its cut-off capacity of the short-circuit current.
- the insulating means 10 according to the invention must in fact respond to a new problem which is that of allowing the electric arc to penetrate inside the protective device 6 while limiting the probability that this arc will come out and become reformed outside the cut-off device 6.
- the insulating means 10 are arranged so as to form a partial insulating barrier between the electrodes 2, 3 and the upstream end 6A of the cut-off device 6.
- partial insulating barrier does not only refer to barriers physical electrically insulating material but also barriers not necessarily physical, but for example electrically insulating, able to prevent the formation of an electric arc between the electrodes 2, 3 and the upstream end 6A of the cut-off device 6 .
- the fractionation plates 7 extend, in consideration of the propagation direction F of the electric arc 5, between a front end 7A and a distal end 7B.
- the front ends 7A and the distal end 7B are situated substantially at the same level as the upstream end 6A and the downstream end 6B of the cutoff device 6.
- the fractionation plates 7 are each provided with a notch 11 separating, at least partially, each splitter plate 7 into two separate branches 7C, 7D.
- the notches 11 form a groove 12 whose shape, for example V, is specifically designed to draw the electric arc 5 inwards In this way, the input area E of the electric arc 5 substantially coincides with the groove 12.
- the insulating means 10 are arranged so as to physically close, at least partially, the upstream end 6A of the cut-off device 6, thus forming a physical insulating barrier between the electrodes 2, 3 and the upstream end 6A of the cutoff device 6.
- the insulating means 10 are arranged to cover, in their entirety, the upstream end 6A of the cut-off device 6 located around, for example on either side, the entry zone E of the electric arc 5.
- the insulating means 10 can thus be arranged, as shown in Figure 3, on either side of the groove 12 so as to cover the front end 7A of the branches 7C, 7D splitting plates 7.
- the insulating means 10 may be formed by one or more rigid strips (not shown) arranged for example on either side of the groove 12 so as to cover the front end 7A
- the rigid strips then preferably extend in a plane substantially perpendicular to the direction of propagation F of the electric arc 5, and coplanar with the plane formed by the front ends 7A of the splitter plates 7.
- the rigid strips may advantageously be perforated with a plurality of orifices in order to allow the flow of air between the diverging space 9 and the cut-off device 6.
- the rigid strips come, by one of their faces, in contact with the front ends 7A of the fractionation plates 7, and preferentially in sealed support on the latter.
- the insulating means 10 are formed by caps 13 arranged to form a partial insulating barrier between the electrodes 2,3 and the upstream end 6A disposed on either side of the groove 12 and designed in such a way that in their operative position they cover the front end 7A of one or more splitter plates 7.
- the caps 13 are arranged so as to completely cover the upstream end 6A of the cut-off device 6 located around the input zone E of the arc.
- the caps 13 are preferably formed by a band 14 that is substantially elongated, intended to cover the front end 7A of a plurality of fractionation plates 7, and from which extends a flange 15 arranged and oriented such that when the cap 13 is in its operative position, the flange 15 naturally come to cover the upper edge 12A of the groove 12.
- the flange 15 of the cap 13 is adapted to penetrate substantially inside the groove 12 when the cap 13 is in its operative position ( Figure 3).
- the cap 13 has a substantially U-shaped cross-section so as to encase the end of the splitter plates 7, in particular branches 7C, 7D, thus substantially matching the shape of said branches 7C, 7D.
- the caps 15 comprise teeth 16 arranged at a distance from each other, preferably at regular intervals, and adapted to be housed between two consecutive splitting plates 7 when the cap 13 is in its functional position.
- the teeth 16 thus make it possible to prevent the deformation and in particular the approach of the splitter plates 7 at their front ends 7A, while improving the insulating properties of the caps 13.
- the insulating means 10 are advantageously integral with the housing 20 of the protection device 1, said housing 20 comprising on the one hand the main electrodes 2, 3 and on the other hand the cut-off device 6.
- the shape of the inner surface of the housing 20 is adapted, for example at the time of manufacture by molding of the housing 20, to present relief structures capable of forming the insulating means 10.
- the insulating means 10 and / or the housing 20 may advantageously be made from a rigid material capable of withstanding the temperature of the arc, for example injected plastic having a good temperature resistance, and even more preferably a resin epoxy or ceramic.
- the insulating means 10 are advantageously formed by one or more strips 17 which are preferably flexible and adhesive. As illustrated in FIG. 5, the strips 17 advantageously cover the front ends 7A of the branches 7C, 7D of the fractionation plates 7, thus forming caps, similarly to the previously described embodiments.
- the tapes 17 are made of insulating material resistant to temperature, and especially to the temperature of the arc.
- the tapes 17 are made from a coated glass fabric, on one of its faces, with a thermosetting silicone type adhesive so as to offer excellent thermal and mechanical resistance.
- the adhesive portion of the ribbons 17 intimately marries the upstream end 6A of the cut-off device 6 in order to fix the ribbons 17 on the latter.
- the insulating means 10 do not form a physical barrier between the electrodes 2, 3 and the upstream end 6A of the cut-off device 6 but an electrically insulating barrier immaterial.
- the insulating means 10 are advantageously formed by an electrically insulating coating 18 deposited over substantially the entire surface of the end portion 7E, located towards the front end 7A, of one or more plates of 7.
- the coating 18 is thus advantageously arranged to come to coat said end portion 7E.
- the coating 18 makes it possible in particular to significantly increase the distance that the electric arc has to travel to form again outside the cut-off device 6. The presence of the coating 18 therefore has the effect of reducing the probability that the electric arc will be reformed between the main electrodes 2, 3, outside the cut-off device 6.
- the insulating means 10 are formed by insulating plates 19 arranged on either side of the groove 12 and interposed between two successive fractionating plates 7 so as to extend, towards the outside of the cut-off device 6, beyond the front end 7A of said splitter plates 7.
- the insulating plates 19 also make it possible to prevent the electric arc from escaping to the outside of the cut-off device 6 by increasing the distance to be traveled by the electric arc to form again outside the cut-off device 6, between the main electrodes 2, 3.
- the cut-off device 6 comprises, at its downstream end 6B, an insulating screen 30 arranged to cover, at least partially, the downstream end 6B of the cut-off device 6. so as to prevent the electric arc 5 from escaping the cut-off device 6 after having passed through it, for example a first time (FIG. 1).
- the insulating means 10 have a crucial role insofar as, after passing through the breaking device 6 according to the direction of propagation F, the electric arc 5 "bounces" on the insulating screen 30 , and returns in a direction substantially opposite to the direction of propagation F, towards the upstream end 6A, of the cut-off device 6.
- the applicant has found that the electric arc 5 goes up preferentially along the branches 7C, 7D of the splitter plates 7 and much more rarely at the central portion 12B of the groove 12.
- the insulating barrier formed by the insulating means 10 makes it possible to significantly reduce the probability of the electric arc escaping at the upstream end 6A of the breaking device 6, thus preventing the electric arc 5 from reforming between the main electrodes 2, 3.
- an electric arc 5 is established between the two main electrodes 2, 3, which allows the flow of the lightning to the ground.
- This electric arc 5 then moves to the cut-off device 6 in which it penetrates at the level of the input zone E, situated substantially in the same plane as the groove 12.
- the electric arc 5 is then decomposed into a plurality of elementary arcs so as to increase the arc voltage of the current with respect to the mains voltage and to limit the intensity of the current flowing through the protection device.
- the elementary electric arcs move towards the downstream end 6B of the cut-off device 6 until they meet the insulating screen 30.
- the protection device 1 therefore has a breaking capacity of the short-circuit current or the following current improved by to the devices of the prior art, and this by limiting the probability that the electric arc, once located inside the cutoff device and decomposed into a plurality of elementary arcs, escapes from the cutoff device to reform on the outside of the latter between the main electrodes.
- the protection device according to the invention has a breaking capacity multiplied by at least two compared to the devices of the prior art.
- the invention finds its industrial application in the design, manufacture and use of protection devices against overvoltages, overloads or short circuits.
