  • the present invention relates to the field of devices for protection of power lines and / or electrical devices against temporary overvoltages.
  • the present invention relates more precisely to a device forming a surge arrester with high energy absorption capacity.
  • surge protection devices so far offered are formed on the basis of a varistor or spark gap, or even a combination of these.
  • the present invention now aims to provide new means with high energy absorption capacity and suitable for allow a natural extinction of a current immediately.
  • a spark gap comprising two electrodes. carried by tabs respective, in which at least one of the tongues is produced in a deformable material so that the distance between the electrodes is elongated when developing an arc between them.
  • the two tongues are made of deformable material.
  • the device comprises means capable of ensuring the passage of the current, in parallel of the tabs, between connection terminals and the electrodes, at least after deformation of the tongues.
  • arc extinguishing means are provided with regard to the interval defined between the two electrodes.
  • FIG. 1 to 3 attached a spark gap conforming to the present invention which comprises a housing 100 housing two tabs 110 which each carry an electrode 150.

  • the housing 100 is adapted to allow attachment on a support rail, such as a standard DIN rail.
  • the housing 100 preferably has a shape generally parallelepiped.
  • the housing 100 preferably has a shape general flattened comprising on a longitudinal edge 101, a protuberance 102 whose outline is itself globally parallelepiped.
  • the two main faces of the housing 100 are visible in the figure 3, under the references 103 and 104.
  • the housing 100 is advantageously made of material electrically insulating.
  • the housing 100 is made of, or coated with, self-extinguishing material, i.e. a material capable of generate a gas promoting the extinction of the arc when this material is licked by an electric arc.
  • the tabs 110 are preferably symmetrical with respect to a median plane P perpendicular to the main faces 103, 104 and forming itself plane of symmetry for the outgrowth 102.
  • the tabs 110 are made of material electrically driver.
  • each tongue 110 is formed of three sections 112, 114 and 116 generally rectilinear.
  • the first two sections 112 are coplanar and adjacent to the second longitudinal edge 105 of the housing 100, that is to say the one opposite to the projection 102. They are adapted to serve as a connection to the lines or electrical equipment to be protected.
  • the second sections 114 converge together towards the center of the housing 100, from the inner end of the sections 112 above.
  • third sections 116 extend the second sections 114 and diverge from each other, away from said second sections 114. These third sections 116 point in the direction of the angles of the protrusion 102, at rest. By way of nonlimiting example, at rest, the third sections 116 typically form an angle of around 60 ⁇ .
  • the third sections 116 each carry an electrode 150, on their facing surfaces.
  • the electrodes 150 are inclined between they, in the form of a dihedral, at rest. Even more specifically, the electrodes 150 diverge from one another, from the point of birth of the arc, ie from their end close to the arrival of the current.
  • each electrode 150 is formed of a patch circular attached to the third section of a tongue 110 by all suitable means, for example by welding, riveting (as illustrated in the appended figures) or any equivalent means.
  • the electrodes 150 must of course be produced in a electrically conductive material, resistant to an electric arc, say having good resistance when subjected to an electric arc.
  • the electrodes 150 can be made of a material to arc extinction, as previously indicated for the case 100.
  • a deposit of arc extinguishing material can be applied directly to the electrodes 150.

  • the supports 160 can also be made of, or coated of, arc extinguishing material.
  • the base of the supports 160 is fixed to the second longitudinal edge 105 from housing 100.
  • summit 162 of supports 160 is preferably oblique to the median plane P, according to an obliqueness which coincides with that of the second sections 114, at rest.
  • the housing 100 illustrated in the appended figures comprises a spark arrester 170, which surrounds the second and third sections 114, 116 as well as the electrodes 150 and the supports 160.
  • this chimney 170 is formed of two walls main 172, 174 planes, parallel to each other, which extend the side walls of the projection 102.
  • the chimney 170 is advantageously made of, or coated with, extinguishing material arc.
  • the walls 172, 174 are provided at their opposite base protrusion 102, of cutouts 173 allowing the passage of second sections 114 with freedom of deformation, as we will explain it later.
  • the housing 100 includes vents 106 designed to allow the escape of gases generated inside the housing 100 under the effect of an electric arc.
  • vents 106 can be provided in the side walls of the projection 102, parallel to the median plane P, and perpendicular to the plane longitudinal 101.
  • the two electrodes 150 are placed in the air.
  • This arc is then supplied by the current on.
  • the angle formed by the two electrodes 150 facilitates the upward stretching of the arc, created by electrodynamic forces, that is to say in approximation of the projection 102 of the housing 100.
  • the tabs 110 are advantageously made of a material deformable under the effect of an arc developed between the electrodes 150.
  • the electrodes 150 are further removed automatically when an electric arc appears between them, which further favors the extinction of the current immediately.
  • Possible deformation of the tabs 110 may be due to forces electrodynamics developed during the appearance of such an arc.
  • the recall of the tabs 110 in the rest position can be obtained by the intrinsic elasticity of the tabs 110 or also by means additional elastic return, such as calibrated springs, which stress the tabs at the second sections 114, towards their rest position illustrated in Figure 1.
  • the tabs 110 are deformed into spacing due to the heating produced in the tabs 110 following the current passing through them to reach the electrodes 150.
  • the tabs 110 are preferably adapted for return to the rest position, at room temperature, thanks to their intrinsic properties.
  • the tabs 110 can for example be formed from heat sensitive bimetallic strips or shape memory material.
  • bimetallic strips or shape memory material allows to improve the deformation of the tongues 110, from the rest position close-up illustrated in FIG. 1, towards a separated position during the appearance of an electric arc illustrated in Figure 2, with reminder automatic to the rest position when the said arc is removed.
  • the housing 100 is provided on its internal surface with a deflector of gas 190 placed opposite the interval defined between the two electrodes 150. More precisely, this deflector 190 is placed on the side electrodes 150 towards which the arc is pushed. So depending on the mode of particular embodiment illustrated in the appended figures, the deflector 190 is placed on the internal surface of the projection 102.
  • the deflector 190 is advantageously made of, or coated with, arc extinguishing material.
  • the electrodes 150 and supports 160 such an arc extinguishing material is not consumed not but projects a substance which promotes the extinction of the arc.
  • the spark gap device further comprises a braid 200 of flexible electrically conductive material, placed in parallel of each tab 110.
  • the braids 200 are placed between the first sections 112 and the third sections 116 of the tabs 110.
  • the braids 200 can be attached to these elements, with electrical contact, by any suitable means, such as for example by welding or mechanical fixing.
  • the braids 200 directly ensure the passage of current from connection section 112 to the electrodes 150.
  • Such braids 200 have a resistance lower than that of the shape memory or bimetal alloy making up the tabs 110 and thus avoid the passage of a large current through the material deformable tabs 110 and therefore avoid a significant heating of these.
  • FIGS. 5 to 7 appended Another variant is shown in FIGS. 5 to 7 appended. of realization on which there is a case 100 which houses two rigid supports 160, two deformable tabs 110 and two electrodes 150.
  • the whole is preferably symmetrical with respect to the median plane P, at rest.
  • the supports 160 are made of material electrically conductor, for example copper. They participate in the flow of the current developing the arc.
  • Each support 160 preferably comprises four sections 1602, 1604, 1606 and 1608.
  • the first two sections 1602 are coplanar and adjacent to the second longitudinal edge 105 of the housing 100, that is to say the one opposite to the projection 102. They are adapted to serve as a connection to the lines or electrical equipment to be protected.
  • the second sections 1604 converge together towards the center of the housing 100, from the internal end of the above-mentioned sections 1602.
  • the third sections 1606 extend the second sections 1604. They are preferably parallel to each other.
  • fourth sections 1608 are coplanar with each other and housed in the outgrowth 102. They diverge from each other away from their connection zone on the third sections 1606.
  • the tabs 110 have the general shape of an "L” with two branches 1100 and 1102.
  • a first branch 1100 of the tongues is pressed against the outer surface of the fourth sections 1608.
  • the first branch 1100 tabs can be connected to this fourth section by all suitable means, for example by welding or riveting in 1609.
  • the second branches 1102 extend parallel to each other, between the two supports 160.
  • the device illustrated in Figures 5 to 7 further comprises a spacer 210 of electrically insulating material interposed between the two tabs 110.
  • the spacer 210 advantageously has the shape of a T.
  • the transverse head 212 of this spacer 210 rests on the outer surface of the tabs 110.
  • the core 214 of the spacer 210 is disposed between the tongues 110.
  • the electrodes 150 are placed on the free ends of the second branches 1102, between the second sections 1604.
  • the tabs 110 are produced in a deformable material when an electric arc appears, for example under the effect of electrodynamic forces, even thanks to properties bimetallic strip or shape memory, with automatic elastic return in rest position.
  • the electrodes 150 are spaced apart due to the deformability properties of tabs 110, to promote extinction of the arc by stretching.
  • the supports 160 provide the current flow to the electrodes 150, in parallel with the tongues 110. This arrangement makes it possible to preserve the tabs 110.
  • the supports 160 then play a role comparable to that of braids 200 according to the embodiment of Figure 4.
  • the deflector 190 placed opposite the defined interval between the electrodes 150 is formed by a crenellated plate.
  • This plate 190 thus forms a baffle which can proceed essentially by mechanical effect, i.e. elongation of the arc, to participate in the extinction of it.
  • the plate 190 is also produced in self-extinguishing material, to reinforce this arc extinguishing effect.
  • the means placed with regard to the interval defined between the electrodes 150, to participate in extinction of the arc can be formed by magnetic means, by example permanent magnet or electric coil, proceeding essentially by lengthening it.
  • spark gap devices allow to cut intensities of up to a few kA at at least about 50 kA, form 10/350.
