Definitions

  • the invention relates to a switchgear terminal with a lower part of the terminal and at least one, together with the lower part of the terminal, forming at least one clamping channel, cross-elastic upper part of the terminal, which has an edge zone on both sides running parallel to the terminal channel and can be clamped to the lower part of the terminal by means of at least one screw.
  • switchgear terminal blocks For a long time it was customary with switchgear terminal blocks to stiffen not only the lower part but also the upper part by means of ribs or the like to such an extent that they are practically rigid. With these terminals, there was a significant deterioration in contact over time, which was at least partly due to creeping of the conductor material, as occurs in particular with stranded conductors. The creeping of the conductor material namely results in a change in shape of the conductor, which the terminal body cannot follow due to its rigid design, which leads to a more or less severe reduction in the contact pressure.
  • the invention is therefore based on the object of providing a switchgear terminal block which is able to compensate for relatively large changes in shape of the conductor clamped in the clamping channel without disturbing reduction in the contact pressure, but is nevertheless inexpensive.
  • the resulting cross-sectional profile shape of the upper part of the terminal which is usually referred to as the cover, in contrast to the profile shapes of the known terminal body parts of switchgear terminal blocks, enables a relatively soft spring characteristic to be realized, by means of which the cover is able, with its contact web or contact webs, to also make major changes in shape Conductor due to flow of the conductor material without significantly reducing the contact pressure. Since the elasticity is achieved solely by the shape of the cover, additional spring elements or the like are not required, the clamp according to the invention is inexpensive and also easy to assemble. In addition, there is the further advantage that the soft spring characteristic also makes it possible to bridge a relatively large conductor cross-sectional area with the terminal, i. H.
  • the design of the clamp according to the invention makes it possible, by virtue of its favorable spring characteristic, when the screws engage in the edge zones, to bring the lateral edge zones of the cover or the cover into contact with the lower part of the terminal in all conductor cross-sections lying in the area of application, as a result of which the cover is used to draw current can be. Accordingly, in the case of those embodiments whose lateral edge zones partially limit the clamping channels, the centrally arranged web can be brought into abutment with the lower part of the terminal and the cover can thus be used for power conduction.
  • the clamp according to the invention therefore comes very close to the ideal case of the round encirclement of the conductor. The result is a reduction in the weight of the clamp and, if several lids are provided, a reduction in the number of lids, which also leads to a reduction in costs.
  • the lower part of the clamp can also be designed in the same way as the cover if a corresponding elasticity of the lower part of the clamp is required or desired.
  • the dimensions of the cover are preferably selected so that the products resulting from the clamping force of the coil material tensions near or above the 8 0th 2 limit of the material.
  • the two edge zones of the cover can have projecting contact elements on their side facing the lower part of the clamp.
  • ring cutting edges can be provided as contact elements, which are arranged concentrically to the holes for the screws.
  • contact elements could also be provided on the lower part of the terminal.
  • the contact web running in the longitudinal direction of the clamping channel has an increasing width towards its free end forming the contact surface. With such a contact web you get both favorable contact conditions and favorable suspension properties.
  • the free end of the contact web preferably forms a groove running in the longitudinal direction of the clamping channel, the flanks of which are the contact surfaces and preferably enclose an obtuse angle.
  • the sections of the cover between the middle zone and the edge zone form a carrier, on which, in different areas, mutually opposing bending moments act due to the force of the clamping screws. It is in the inner region adjacent to the central zone with the contact web that there is an internal bending moment directed downwards (towards the lower part of the terminal) which, if it were only effective, would cause the edge zone in question to be inclined in such a way that the section of the edge zone furthest away from the central zone would be more closely approximated to the lower part of the clamp.
  • the inclined positions of the edge zones cancel due to the inner bending moment and the outer bending moment, so that the edge zones experience a pure parallel displacement during the clamping process as whether the carriers in the sections between the central zone and the lateral edge zones of the cover at the moment-free point, i. H. would be provided with a joint at the point between the area of the inner bending moment and the area of the outer bending moment.
  • the lid preferably has a minimal thickness at the two moment-free locations of the sections between the central zone and the peripheral zones.
  • a switchgear terminal for connecting two conductor ropes arranged coaxially in the region of their mutually facing ends has a lower part 1 which extends over the entire terminal length and is stiffened by a longitudinal rib 2 and transverse ribs 3 and therefore how a rigid body practically does not deform under the action of the forces acting on it.
  • the lower part 1 is assigned two covers 4 of the same design which are arranged next to one another in their longitudinal direction and have a strongly rounded outer contour. In the exemplary embodiment, this outer contour corresponds to the outer contour of the lower part 1 in the region of its transverse ribs 3. However, more than two or only one cover could also be provided.
  • the flat inner surface 5 of the lower part 1 facing the two covers 4 is interrupted in the longitudinal center zone by a conductor channel 6 which is semicircular in cross section and open towards the covers, which extends over the entire length of the lower part 1 and the cooling channel 7 in the region of the lower part 1 limited.
  • the conductor channel 16 could also have a different contour if this would be necessary to adapt to different conductor cross sections or for other reasons.
  • the lid 4 are preferably made of an elastic material and as an extruded profile or pressed part.
  • the lower clamp part can be a cast body or a pressed part. In contrast to the latter, the lids are not rigid, but are made transversely elastic.
  • the cross-sectional profile of the cover 4 is, apart from a contact web 14 lying in the longitudinal central zone, extending over the entire length of the cover and projecting towards the lower part 1, since the two lateral edge zones 9 and 9 'are angled inwards, that is to say face each other and thus face the one or the other part of the inner surface 5 interrupted by the conductor channel 6 in the assembled state.
  • the width of the cover 4, as shown in FIG. 1, is adapted to the width of the lower part, and as at the transition from the outer surface of the lower part 1 to the side surface 5, the edges 4 are also at the transition from the outer surface 10 to the cover 4 Bottom 1 facing outer sides of the edge zones 9 and 9 'rounded.
  • the edge zones 9 and 9 'lying parallel to the inner surface 5 in the assembled state are penetrated in the exemplary embodiment by two threaded bores 12 spaced apart from one another in the longitudinal direction of the clamp, the longitudinal axis of which is perpendicular to the outside 11 and which are each aligned with a through hole 13 in the lower part of the clamp.
  • the number of threaded bores 12 which each cover 4 has depends on its size, in particular on its length, and can be chosen according to the requirements.
  • the edge zones 9 and 9 'each have a strip-like thickening on their inside.
  • the wall thickness of the cover 4 increases, as shown in FIG. 1, from the point of transition to the edge zone 9 or 9 'towards the central zone, in which a contact web 14 projects from the inside towards the clamping channel 7 and is symmetrical to the longitudinal central plane of the lid is formed and extends over its entire length.
  • the contact web 14, as shown in FIG. 1 has a fishtail-like cross-sectional shape, i. H. the fillet adjoining the inner surface 15 of the cover 14 widens at its base from a value that is approximately half the diameter of the clamping channel 7 towards its free end to a value almost twice as large, and that The free end forms a groove 16 which extends over the entire length of the web and is oriented towards the conductor channel 6.
  • Narrow slots are provided between the pole horn-like lateral end regions of the contact web 14 and the edge zones 9 and 9 ', so that the edge zones 9 and 9' are relative to the Can move the contact bridge. Otherwise, however, the two cavities 17 formed by each cover 4 and extending over the entire length of the cover are closed on their circumference.
  • the flanks 18 of the throat 16 are flat in the exemplary embodiment and form an obtuse angle, which is selected such that there is good contact with the conductor lying in the clamping channel.
  • the bottom of the throat 16 is rounded.
  • the covers 4 are pulled against the lower terminal part by means of screws 19 which penetrate the through bores 13 and engage in the threaded bores 12. Large, reinforced washers 22 are placed under the screw heads.
  • the contact web 14 is supported on the conductor lying in the conductor channel 6, so that the cover 4 is deformed along the dash-dotted lines 20.
  • the large length of these lines 20 results in a relatively soft spring characteristic, which enables the covers 4 to deform Conductors such as occur, for example, as a result of creeping of the conductor material, without the clamping pressure exerted on the conductor in the clamping channel 7 by the lower part 1 and the covers 4 only decreasing slightly.
  • the cap 4 are dimensioned so that by the clamping force of the bolts 19 caused material stresses in the lid near or above the 8 0th 2 limit of the material.
  • the tension occurring in the cover then drops until an equilibrium is established between the contact pressure of the cover on the cable and the creep resistance of the cable material. For materials without a pronounced yield point, 0.2% permanent elongation is allowed.
  • the soft spring characteristic of the cover 4 would also allow the screws 19 to be tightened beyond the position of the cover 4 shown in the left half of FIG. 1 until the outside 11 of the edge zones 9 and 9 'on the inside surface 5 of the Lower part 1 is present.
  • Such extensive deformation of the cover 4 has the advantage that it can be used in addition to the lower part 1 for power transmission.
  • FIG. 2 An embodiment in which such contact improvement is ensured is shown in FIG. 2.
  • the exemplary embodiment according to FIG. Differs from the exemplary embodiment according to FIG. 1 only by this contact improvement, which is why the corresponding parts are provided with reference numbers that are one hundred times larger.
  • the clamp according to FIG. 2 is designed in the same way as that according to FIG. 1, it has the same advantages as this one, that is to say also the relatively soft spring characteristic, which largely excludes a drop in the clamping pressure due to creeping of the material and also allows the clamp to be adapted to conductors with very different cross sections.
  • the clamp according to the invention can not only be designed as a connecting clamp. Rather, it can replace all those types of terminals that have a lower part and at least one cover, as is the case, for example, with branch terminals.
  • a switchgear terminal for connecting two conductor ropes arranged coaxially in the region of their mutually facing ends has, as shown in FIG. 1, a lower part 201 which extends over the entire terminal length and which is stiffened by a longitudinal rib 202 and transverse ribs 203 and is therefore practically not deformed like a rigid body under the action of the forces acting on it.
  • the lower part 201 is assigned two covers 204 of the same design which are arranged next to one another in their longitudinal direction and which have a strongly rounded outer contour. However, more than two or only one cover could also be provided.
  • the flat inner surface 205 of the lower part 201 facing the two covers 204 is interrupted in the longitudinal center zone by a conductor channel 206 which is semicircular in cross section and open towards the covers, which extends over the entire length of the lower part 201 and a clamping channel 207 in the region of the lower part 201 limited.
  • the conductor channel 206 could also have a different contour if this would be necessary to adapt to different conductor cross sections or for other reasons.

  • the lower clamp part can be a cast body or a pressed part. In contrast to the latter, the lids are not rigid, but are made transversely elastic.
  • the cross-sectional profile of the covers 204 is, apart from a contact web 214 which lies in its longitudinal central zone 208 and extends over the entire length of the cover and projects towards the lower part 201, since the two lateral edge zones 209 and 209 'are angled inwards, thus point towards each other and, as a result, lie opposite one or the other part of the inner surface 205 interrupted by the conductor channel 206 in the assembled state.
  • the width of the cover 204 is adapted to the width of the lower part, and as at the transition from the outer surface area of the lower part 201 to the inner surface 205, the edges at the cover 204 are also at the transition from their outer surface area 210 to the lower part 201 - facing outside 211 of the edge zones 209 and 209 'rounded.

  • the number of threaded bores 212 which each cover 204 has depends on its size, in particular on its length, and can be chosen according to the requirements. In order to obtain the greatest possible length of the threaded bores 212, the edge zones 209 and 209 'each have a strip-like thickening on their inside.
  • the contact web 214 projecting from the inside of the central zone towards the clamping channel 207 is symmetrical to the longitudinal center plane of the cover and extends over its entire length.

  • the contact web 214 due to the spring force of the deformed sections 221 and 221 ', can follow deformations of the conductors, such as occur, for example, as a result of creeping of the conductor material, without the clamping pressure acting on the conductor in the clamping channel 207 from Lower part 201 and the cover 204 is exercised, noticeably decreases.
  • Fig. 3 shows the state of the switchgear terminal before tightening the screws 219, ie before moving the outer sides 211 of the cover against the inner surfaces 205 of the lower part 201.
  • a special feature of the switchgear terminal shown here is that the edge zones 209 and 209 'of the cover only experience a parallel displacement when tightening, ie only move towards the lower clamp part 201 in such a way that the outer sides 211 of the edge zones always remain parallel to the facing inner surfaces 205 of the lower part 201 under all the bending moments that are present.

  • the lid can be made very thin at point O, since it is moment-free. With regard to the Characteristic curves for the resilient deflection of the cover result in particularly favorable conditions.
  • the fourth exemplary embodiment shown in FIGS. 6 and 6 differs from the previously described exemplary embodiments primarily in that two clamping channels 307 which are located parallel and at a distance from one another are provided.
  • the lower clamp part 301 which is a substantially rigid body and is, for example, cast or pressed, is therefore provided with two conductor channels 306 which are open towards the covers 304 and which extend over the entire length of the lower part.
  • the flat inner surface 305 of the lower terminal part 301 facing the covers lies between these two conductor channels.
  • the lower clamp part 301 is assigned two covers 304 of the same design, which are arranged next to one another in the longitudinal direction of the two clamp channels 307 at a short distance.
