Description

The invention relates to the general field of transport and distribution of electrical energy, in particular over medium voltage overhead networks, by means of insulated electrical cables (that is to say protected by a sheath made of insulating material ). The invention more particularly relates to anchoring systems for insulated electrical cable, comprising an anchor clamp and a connector for electrically connecting the insulated electrical cable to the anchor clamp. The invention also relates to methods for anchoring such cables with such an anchoring system. Such anchoring systems are already known operating both a mechanical connection and an electrical connection between the anchor and an electrical cable protected by a sheath of insulating material. It should be noted that with high voltage levels (medium voltage), the insulating sheath is also at a high potential (in addition to the core of the cable) and is therefore not strictly speaking an insulating sheath ( such a sheath serves essentially to reduce the electric field of the power line with respect to a bare cable and makes it possible to put two neighboring cables at a different potential at a smaller distance than if the cables were bare). In the present specification, to simplify the terminology, such a sheath of insulating material is simply called insulating sheath. European patent EP 1 384 299 discloses such a system formed by an anchoring clamp comprising a metal body, metal anchoring arms fixed to the body, a clamping member formed by metal wedge portions moving relative to each other. to the body and a clamping and holding device located in close proximity to the corner portions between the anchor arms at the widest end of these corner portions. The body forms a slideway in which the corner portions are at least partially inserted and a space is provided between these corner portions for receiving an insulated electrical cable, i.e. a cable having a conductive core protected by a sheath. insulating. When the cable is pulled from the side of the narrower end of the corner portions (end opposite the wider end), the corner portions move relative to the body and tighten the cable. The clamping and holding device is provided with a cable receiving space and comprises teeth which, under the action of a clamping screw, penetrate through the insulating sheath of the cable to, on the one hand, mechanically hook to this cable and, on the other hand, connect to it electrically. The clamping and holding device forms, by its mechanical fastening to the cable, an abutment on the latter which comes to bear against the widest end of the corner parts when the cable is pulled from the side of the end minus wide of these corner parts, so as to push the corner parts into the body and thus tighten the cable. The clamping and retaining device also forms, by its electrical connection to the cable and its application in abutment against the metal corner parts, an anti-tracking piece (in English: anti-tracking) allowing to flow in the clamp via the corner portions, a possible potential balancing current from a very large potential difference between the conductive core and massive metal elements (for example the body of the clamp). The clamping and holding device thus makes it possible to avoid any electrical arcs on the surface of the insulating material, known as tracking.

The invention aims to provide an anchoring system of the same kind but with improved performance, both mechanical and electrical, while being particularly simple, convenient and economical. The invention thus has, in a first aspect, an anchoring system for an insulated electrical cable provided with a conductive core and an insulating sheath covering said conductive core, comprising an anchor clamp and a connector configured to electrically connecting said insulated electrical cable to said anchor clamp, said anchor clamp comprising an elongated metal clamp body which longitudinally forms a slide, a clamp member slidably engaged in said slide and which has a housing configured to receiving said insulated electrical cable, and a metal anchor loop which is attached to said clamp body and configured to be secured to any support, said connector having a first receiving space configured to receive said insulated electrical cable and a first housing member. conductive contact having conductive teeth each having an active portion configured to perforate the said insulating sheath and come into contact with said conductive core of said insulated electrical cable; characterized in that said connector further includes a second receiving space configured to receive a portion of said anchor loop and a second conductive contact member separate from said first conductive contact member and configured to be in contact with said first lead member. conductive and movable contact in translation along said portion of said anchor loop while being directly electrically attached thereto. The anchoring clamp of the anchoring system according to the invention is configured to clamp the insulated electrical cable in its metal clamp body, especially when the cable is secured to any support, such as an electric pole.

The connector of the anchoring system according to the invention is configured to discharge, in case of occurrence of a potential difference between said anchor clamp and said cable insulating sheath, a potential balancing current between this clamp anchor and this insulating sheath, regardless of the stowage of the cable and its position in the anchor.

In other words, the anchoring system according to the invention makes it possible, thanks to the fact that the second conductive contact member of the connector is directly electrically connected to the anchor loop (which itself is fixed to the body of the clamp of anchoring) while being movable in translation relative to this handle, to ensure electrical contact between the cable and the clamp body (via the handle) regardless of the clamping state of the cable in this clamp. Note that there is no need for mechanical contact between the second conductive contact member and the portion of the anchor loop; but it suffices that the preferential path of current flow (path of lower dielectric strength) exists between this second conductive contact member and this portion of the anchor loop. Note that with the anchoring system according to the invention, the clamping member of the anchor can be made of metal, plastic or rubber or composite. The anchoring system according to the invention is therefore particularly simple, convenient and economical. According to preferred, simple, convenient and economical characteristics of the anchoring system according to the invention: said second conductive conductive contact member comprises a metal sleeve configured to wrap, in sliding contact, said portion of said anchor loop ; said first conductive contact member further includes conductive teeth each having an active portion configured to press tightly against said metal sleeve; said connector comprises two jaws and at least one clamping member for bringing said two jaws closer to each other, each said jaw comprising a body of rigid insulating material provided with said first conductive contact member, which element has said parts each configured to protrude from a receiving face of said jaw respectively to penetrate said conductive core of said insulated electrical cable and to engage said second conductive contact member, which is configured to engage said portion of said anchoring loop, the receiving face of each jaw being opposite the receiving face of the other jaw with each active part of a jaw to the right of an active part of the other jaw, said connector being configured to take a positioning position of said cable and said anchor loop between said receiving faces of said cheeks res with said first and second contact members respectively at said cable and said anchor loop, to take a service position where said cable and said anchor loop are sandwiched between the jaws, with said first member conductive contact member which has penetrated into said conductive core and said second conductive contact member which has come into electrical contact with said anchor loop, and to move from the setting position to the service position by bringing the jaws into contact with said clamping member; each said jaw has its receiving face disposed facing a portion of a metal sleeve forming said second conductive contact member and configured to wrap, in sliding contact, said portion of said anchor loop; said clamping member of said anchor clamp comprises at least two movable sliding clamping wedges in said slideway and each provided with a first end near said anchor loop and a second end, opposite said first end, remote from said anchor loop, said connector being located at least on said anchor loop and at a distance from said first end of each clamping wedge - said clamping member of said anchor clamp is configured to to deform radially and is provided with a contact pad with a high coefficient of adhesion; - said slide of said anchor has a continuously variable width over at least part of its length; and / or - said insulated electrical cable is a medium voltage aerial cable intended to be secured to an electrical pole. The invention also relates, in a second aspect, to a method of assembling an anchoring system, characterized in that it comprises the following steps: providing an anchoring clamp comprising a clamp body metallic and elongate member which longitudinally forms a slideway, a clamping member slidably engaged in said slideway and having a housing 30 configured to receive said insulated electrical cable, and a metal anchor loop which is attached to said body and configured to be secured to any support; providing a connector configured to electrically connect said insulated electrical cable to said anchor clamp and which comprises a first reception space configured to receive said insulated electrical cable and a first conductive contact member provided with conductive teeth each having an active portion configured for perforating said insulating sheath and contacting said conductive core of said insulated electrical cable, as well as a second receiving space configured to receive a portion of said anchor loop and a second conductive contact member separate from said first contact member conductor and configured to be in contact with the first conductive contact member and movable in translation along said portion of said anchor loop while being directly electrically attached thereto; - providing an insulated cable provided with a conductive core and an insulating sheath covering said conductive core; introducing said insulated electrical cable into said slideway of said body of said anchor clamp; mounting said connector on a portion of said insulated electrical cable, which is received in said first reception space of said connector, and on said portion of said anchor loop, which is received in said second reception space of said connector; then perforating said insulating sheath with said active portions of said conductive teeth of said first conductive contact member for mechanically securing and electrically connecting said insulated electrical cable to said connector, and electrically securing said second conductive contact member directly with said portion of said anchor loop said second conductive contact member being configured to be movable in translation along said portion of said anchor loop. The assembly method of the anchoring system according to the invention is particularly simple and convenient to implement. We will now continue the disclosure of the invention by the description of an embodiment, given below by way of illustration and not limitation, with reference to the accompanying drawings in which: - Figure 1 shows schematically the anchoring of an insulated electrical cable on an overhead transmission and distribution network of medium voltage electrical energy through two anchoring systems according to the invention; FIG. 2 is a perspective view of one of the two anchoring systems of FIG. 1, the cable being tightened therein; - Figures 3 and 4 are respectively side and top views of the anchoring system of Figure 2; - Figure 5 is a partial sectional view taken along a median plane of the anchoring system of Figure 2, essentially showing a body of an anchor of this system; and - Figure 6 is a partial sectional view marked VI-VI in Figure 4, essentially showing a connector of the anchoring system. FIG. 1 shows the anchoring, or stowage, thanks to two anchoring systems 1, a medium voltage insulated electrical cable 2 to a securing piece of an electric pole 6 fixed to the ground (no represent).

This lashing piece is here formed of two columns 33 fixed on each side of the post 6 and two insulators 32 each provided with a first end 34 and a second end 35, which second end 35 is opposite the first end. 34. Each insulator 32 is fixed at its first end 34 to a respective column 33. The insulated electrical cable 2 is hooked to the electrical pole 6 by two anchoring systems 1 which are each anchored or stowed at the second end 35 of a respective insulator 32. The insulated electric cable 2, which is continuous, has two stretched portions 3 and an unstretched portion 4 formed between the two stretched portions 3 and interposed between the two anchoring systems 1. We will now describe in more detail in 2 to 6 an anchoring system 1, the insulated electrical cable 2 being connected thereto. This insulated electrical cable 2 comprises a central conductive core 9, 30 for example copper or aluminum, and a sheath of insulating material 8 covering the conductive core 9. To simplify the terminology, we will call in the following description the sheath of insulating material "insulating sheath 8". The anchoring system 1 comprises an anchoring clamp 10 and a connector 50 configured to electrically connect the insulated electrical cable 2 to this anchoring clamp 10. The anchoring clamp 10 comprises a metal clamp body 11, a clamping member 13 slidably received in this body 11 and an anchoring loop 15 fixed to the body 11. The clamp body 11 longitudinally forms a slide 12 of continuously variable width over at least part of its length. This clamp body 11 comprises, for the formation of the slide 12, two side walls 16 which extend longitudinally obliquely relative to one another and which are connected to one another by a bottom 17 , substantially along a U-shaped cross section of the clamp body 11.

This clamp body 11 therefore has a first end and a second end opposite the first end, with the first end being wider than the second end. The clamp body 11 further comprises a plurality of transverse ribs 18 formed on the side walls 16.

At its first end, the clamp body 11 comprises, against this side wall 16, bosses 19 at which is fixed the anchor loop 15. This anchor 15 is metal and has two arms 20 connected to one another by a bent portion 22.

Each arm 20 has a threaded free end 21 passing through an orifice 28 formed in a boss 19 of the clamp body 11 (FIG. 5). A system of double nuts 23 is fixed on each of the threaded free ends 21 in order to fix the anchoring loop 15 to the clamp body 11. Thus, the anchoring loop 15 is mechanically fastened to the clamp body 11, these two elements being metallic. It will be observed that the arms 20 of the loop 15 extend longitudinally in a plane similar to that in which the clamp body 11 extends and the arms 20 are, at the first end of the clamp body 11, sufficiently spaced to allow the passage of the insulated electrical cable 2 (and more precisely its untensioned portion 4 when the anchoring system is secured to the electric pole 6).

The clamping member 13 is slidably taken in the slideway 12 of the clamp body 11 and is radially deformable. This clamping member 13 has two wedges 24 each extending partly inside the slide 12 and cooperating with the latter by an outer wall 25, while the inner walls 26 of these wedges 24 form a housing 14 configured to receive the insulated electrical cable 2. The corners 24 form here a contact pad having a high coefficient of adhesion. It will be observed that the corners 24 are here arranged diametrically opposite one another and engaged with a groove formed in the slide 12 of the clamp body 11. For each corner 24, this groove is formed by the internal faces of the bottom wall 17 and the side walls 16 of the clamp body 11. It will be noted that drive means (not shown) are provided between the wedges 24 so as to secure them to each other movement in the slide 12. These drive means comprise a bar on one of the wedges 24, which extends transversely with respect to a longitudinal axis of the slide 12, and a ring on the other of the corners 24 in which the bar is slidably engaged. It will be further noted that the sidewalls 16 of the clamp body 11 are configured to form a guide carriage for each of the wedges 24 to guide them as they slide in the slide 12. Each wedge 24 has, like the clamp 11, a first end and a second end opposite the first end, with the first end being wider than the second end. Each corner 24 further has a gripping block 30 in the immediate vicinity of its first end, projecting from an upper face 27 of this wedge 24.

The connector 50 is here configured to electrically connect the insulated electrical cable 2 and more precisely its non-tensioned portion 4 to an arm 20 of the metal anchor loop. The connector 50 is here a jaw connector.

The connector 50 comprises a jaw 51, a jaw 52 and a clamping member 53. The clamping member 53 is a fuse screw-nut pair configured to bring the two jaws 51 and 52 together when the screw is rotated. towards one another in order to firmly grip the non-tensioned portion 4 of the insulated electrical cable 2 and to grip the arm 20 of the anchoring loop 15 while allowing it to slide between the two jaws 51 and 52. Each of the jaws 51 and 52 has a receiving face 54. The receiving face 54 of the jaw 51 is opposite the receiving face 54 of the jaw 52.

Each receiving face 54 has a receiving zone 55 and a receiving zone 56 (FIG. 2). Note that the receiving areas 55 of the jaws 51 and 52 define a first receiving space while the receiving areas 56 of the jaws 51 and 52 define a second receiving space.

It will be observed that FIG. 6 shows only the receiving zones 56 of the receiving surfaces 54 of the two jaws 51 and 52. As can be seen in FIG. 2, the non-tensioned portion 4 of the insulated electrical cable 2 is put into place in the connector 50 between the receiving zone 55 of the jaw 51 and the receiving zone 55 of the jaw 52 (that is, in the first receiving space). The portion of the arm 20 of the anchor loop 15 is in turn placed between the receiving zone 56 of the jaw 51 and the receiving zone 56 of the jaw 52 (in other words in the second receiving space). (see also Figure 6).

As best seen in FIG. 6, each of the jaws 51 and 52 comprises a body 57 of rigid electrically insulating plastic material and conductive contact members 59 and 61 (also called respectively first conductive contact member 59 and second contact member driver 61). From each receiving face 54 project active parts 60 of the first conductive contact members 59.

Each (first) conductive contact member 58 is made of a rigid U-shaped conductive metal plate with a central branch and two distal branches. Each distal branch ends with an active portion 60 provided with a plurality of pointed teeth arranged side by side.

The teeth of the active portions 60 of the receiving zone 55 of each jaw 51 and 52 are sized according to the section of the conductive core 9 of the insulated electrical cable 2 and the thickness of the insulating sheath 8 of the latter. Indeed, these teeth have the role of perforating the insulating sheath 8 and penetrating the conductive core 9 of the unstretched portion 4 of this insulated electrical cable 2 when the jaws 51 and 52 are close to each other by the clamping member 53, thereby creating an electrical connection between the conductive contact members 59 and the conductive core 9 of the insulated electrical cable 2.

The second conductive contact member is formed by a metal sleeve 61 configured to wrap, in sliding contact, the portion of the arm 20 of the anchoring loop 15. This metal sleeve 61 is formed in one piece from a metallic tube and is configured to be attached and disposed respectively on the receiving faces 54 of the jaws 51 and 52. This metal sleeve 61 forms a tubular casing around the portion of the arm 20 of the anchor loop 15 and is dimensioned according to the section of this arm 20. Note that the teeth of the active portions 60 of the receiving zone 56 of each jaw 51 and 52 are further configured and dimensioned according to this metal sleeve 61 and more specifically to their hardness, or independently of this sleeve 61.

Indeed, these teeth do not have the role of perforating the outer face of the sleeve 61 but simply to come close against the latter, or to penetrate slightly the outer face in the latter, when the jaws 51 and 52 are close together. one of the other by the clamping member 53, thereby creating an electrical connection between the arm 20 of the anchor loop 15 and the metal sleeve 61. Each conductive contact member 59 thus comprises an active part 60 intended to to be in contact with the untensioned portion 4 of the insulated electrical cable 2 and another active portion 60 intended to be in contact with the metal sleeve 61, which is intended to be in contact with the arm 20 of the anchor loop 15. Note that the central branch of each conductive contact member 59 electrically connects the two active parts 60, and therefore the branch 20 of the anchor loop 15 is electrically connected to the insulated electrical cable 2 when ls are in place in the connector 50. Note that the metal sleeve 61, in addition to ensuring electrical subjection with the arm 20 of the anchor loop 15, is movable in translation, by friction, along this 20. In other words, the metal sleeve 61 is directly electrically attached to the arm 20 of the anchor loop 15 while it is slidably sliding on the latter. The jaws 51 and 52 furthermore comprise an outer face, respectively 63 and 64. The jaw 51, called the upper jaw, has on its external face 63 a marking (not shown) representative for example of the manufacturer's name of the connector 50. jaw 52, called the lower jaw, has on its outer face 64 a chimney 65 which projects from this outer face 64 and which extends to a free end 66. The chimney 65 has an outer surface and an inner surface defining a well opening through an orifice 67 located at the free end 66.

The outer surfaces 63 and 64 both have a hexagonal cross section. The nut of the clamping device 53 is immobilized in rotation in the well defined by the chimney 65.

We will now describe the method of assembly of the insulated electrical cable 2 with the anchoring system 1 and more precisely, successively, the anchoring of the anchor 10, the insertion of the cable 2 into the anchor clamp 10, the clamping of this cable 2 in the anchoring clamp 10 and the mounting of the connector 50 on both the cable 2 and the arm 20 of the handle 15. For the implementation of the anchoring system 1 , the metal sleeve 61 of the connector 50 is first mounted around one of the arms 20 of the anchoring loop 15. The anchoring loop 15 is then stowed at its bent portion 22 at the second 35 end of the insulator 32. The arms 20 are then attached to the clamp body 11 through the bosses 19 and double nut systems 23. The corners 24 of the clamping member 13 are moved back in the slide 12 of the clamp body 11 on the side of the first end of the clamp body 11, 20 until the space thus cleared between these wedges 24 is sufficient to be introduced into the housing 14 corresponding to the insulated electrical cable 2 to stow. This is a position of installation of the anchor 10. The insulated electrical cable 2 is thus introduced into the housing 14. 25 The corners 24 are manually pushed so as to perform a first tightening of the cable In fact, these wedges 24 then close themselves on the insulated electrical cable 2 and, taking into account the high coefficient of adhesion occurring between these corners 24 and the sheath. 8 insulated electrical cable 2, no sliding occurs between these wedges 24 and this insulated electrical cable 2. The insulated electrical cable 2 is gradually tightened, without sliding relative to the corners 24 which surround it.

The fact that the anchor 10 is secured by the anchor loop 15 causes the insulated electrical cable 2, because of its weight, to be pulled from the side of the second end (the less wide) of the clamp body 11 and thus to lead the corners 24.

These wedges 24 again close themselves on the insulated electrical cable 2 and the insulated electrical cable 2 is still gradually tightened, without sliding relative to the corners 24 which surround it. The clamping is done both longitudinally in the slideway 12 of the clamp body 11 and transversely by the deformation of the wedges 24. As can be seen in FIGS. 2 to 5, when the insulated electrical cable 2 is clamped in the clamp of FIG. 10, the clamping member 13 and more particularly the wedges 24 extend outside the slide 12 formed by the clamp body 11. The connector 50 is then mounted on the unstretched portion 4 of the electric cable isolated 2 secured and tight, which untensioned portion 4 protrudes from the first end of the clamp body 11 and on one of the two arms 20 of the anchor loop 15. For this, the connector 50 is in a position of setting place 20 of the insulated electrical cable 2 and the arm 20 of the anchor loop 15. The receiving faces 54 are thus sufficiently distant from each other to allow the insulated electrical cable 2 to be disposed on the side which the we see on the right in Figure 2, and the arm 20 of the anchor loop 15 on the side that is seen on the left in this same figure. A tool such as a wrench is then engaged on the head of the clamping member 53 to rotate the screw in the screwing direction, so that the jaws 51 and 52 come closer to one another. other, with some of the active parts 60 which perforate the insulating sheath 8 of the insulated electrical cable 2 and then penetrate into the conductive core 9 of the latter, and with some other active parts 60 which bear tightly on the metal sleeve 61, even penetrate slightly into the material of the latter, which envelops a portion of the arm 20 of the handle 15, while being movable in translation on the latter (by sliding with friction). When the jaws 51 and 52 are close together, the connector 50 is then in its operating position where it is secured mechanically and integrally to the insulated electrical cable 2 with which it is further electrically connected, and where it is further electrically secured by by means of a mechanical contact allowing sliding, by friction, with the arm 20 of the anchoring loop 15, which is mechanically secured and electrically connected to the clamp body 11.

Thus, thanks to the first and second conductive contact members 59 and 61 which form an anti-tracking part, a possible potential balancing current resulting from a very large potential difference between the conductive core 9 of the insulated electrical cable 2 and solid metal elements such as the clamp body 11 can be drained by this anti-tracking part in the clamp 10 and more precisely in the clamp body 11 via the arm 20 of the anchoring loop 15. This thus avoids any arcing at the surface of the insulating sheath 9 of the insulated electrical cable 2. The connector 50 therefore forms here an electrical protection which is operational as soon as the latter is both electrically connected to the insulated electrical cable 2 and the arm 20 of the anchor loop 15, regardless of the position of the connector vis-à-vis the clamp body 11 and the corners 24 of the clamping member 13 O It will be noted that the insulated electrical cable 2 can still move relative to the clamp body 11 once the cable 2 is secured, and this displacement causes the connector 50, which is fixedly secured to this insulated electrical cable 2, which connector 50 moves therefore relative to the arm 20 of the anchor loop 15 to approach the clamp body 11. As indicated above, this displacement of the connector 50 relative to the anchor loop 15 is possible thanks to the metal sleeve 61 of this connector 50 which is slidably mounted on the arm 20 of the anchor loop 15, while being constantly electrically connected thereto.

In variants not shown: - the anchor is provided with more than two corners, for example three, four or five corners; the connector comprises conductive contact members which are provided with conductive teeth having active portions only at the receiving regions of the jaws which are configured to receive the insulated electrical cable, whereas these conductive contact members have, at the receiving areas of the jaws which are configured to receive the anchor arm, a curved portion having a substantially planar surface for tight abutment against each of the metal sleeve; - The metal sleeve is integrated in the respective body of the jaws of the connector or reported in the second receiving space; the connector is electrically connected to any one of the arms of the anchor loop, or even to the two arms of the latter; and / or - the insulated electrical cable is an overhead cable for high voltage electrical networks. It is recalled more generally that the invention is not limited to the examples described and shown. 20
