Definitions

  • the invention is based on an active part for a surge arrester according to the preamble of claim 1.
  • the invention refers to a prior art, as it results from EP 0614 198 A2.
  • One in this state of the Technology described surge arrester contains several cylindrical resistance elements with varistor behavior, which column-shaped stacked between two power connection fittings are arranged.
  • One the varistors and the two connection fittings to form an axially acting Contact force cohesive clamping part has at least two with their ends resting on the connection fittings Loops up.
  • a cast housing made of a weatherproof Plastic surrounds the varistors, the loops and the most of the connection fittings.
  • the task is based, an active part of to create the aforementioned type, which despite simple construction due to good mechanical and electrical Characteristics distinguishes and which at the same time in particularly inexpensive manner can be produced.
  • the active part according to the invention faces the prior art the Advantage on that there is only a single loop for Fixing and clamping two connection fittings and at least one held between the valves varistor needed. Therefore, it can be special in particular be made economically.
  • To his assembly becomes just a pre-made and temporarily a axial guide ensuring template needed in the Connection fittings and the at least one varistor first stacked in the form of a column and then by attaching the Loop to form a bias to mechanical stable active part of the surge arrester connected become. Since in this case the axis of the column-shaped Active part, the loop ends substantially symmetrical penetrates, the loop creates a in the entire active part uniform contact force. When an overvoltage occurs is thus a uniform current density of one in the active part ensured discharge current and is therefore a Inadmissibly high local heating of contact transitions of the Active part avoided with great certainty.
  • connection fitting 1 is with a trained as a screw hole 11 fastening device for a not shown on high voltage potential provided with an executable electrical conductor.
  • connection fitting 2 is with a fastening screw 12 formed as a fastening device feasible at earth potential.
  • She has one axially aligned threaded hole 3, in which a pressure screw 4 is guided displaceably in the axial direction.
  • Numeral 5 denotes a loop of a wound, glass fiber reinforced and in a plastic matrix embedded band. The loop 5 is with both ends in slit-shaped sections of material recesses 6, 7 out, which in the connection fittings 1, 2 are formed.
  • connection fittings 1, 2 is to form a columnar Ableitergots a cylindrical varistor element 8 of non-linear resistance material, about the base of metal oxide, such as in particular ZnO arranged.
  • a columnar Ableitergots a cylindrical varistor element 8 of non-linear resistance material, about the base of metal oxide, such as in particular ZnO arranged.
  • metal oxide such as in particular ZnO arranged.
  • an element 8 and two or more columnar stacked varistor elements be provided.
  • connection fitting 1 In a molded into the connection fitting 1 disc-shaped Recess are electrically conductive parts, namely two contact pressure generating and each as a plate spring trained spring elements 9 and one preferably made Aluminum or copper or an aluminum or copper alloy existing thrust washer 10, in the axial direction slidably mounted (Fig.2).
  • a disc-shaped Recess of the connection fitting 2 In a disc-shaped Recess of the connection fitting 2 is one of the same Material as the part 10 existing thrust washer 13 also Slidably mounted in the axial direction (Fig.2).
  • current transfer elements 14 Between the pressure plate 10 and the varistor element 8 and between the Thrust washer 13 and the varistor element 8 are current transfer elements 14 arranged, which in each case as a disc with concentrically guided around the axis and in the two end faces the disc formed grooves are formed (Fig.3).
  • the current transfer elements 14 are advantageous with soft annealed aluminum formed.
  • each of the reference numerals 15, 16 marked slot-shaped sections in essentially transverse to the axis z of the outer surface of the Electric connection fitting 1 and 2 extends over the axis z is.
  • Each of the two ends of the loop 5 is above the axis z out into the slot-shaped section 15 or 16 introduced and lies in each case on a slit-shaped section 15 and 16 delimiting surface 17 and 18 ( Figure 3).
  • This ensures that the loop 5 in the area of Axis z is held centrally and a uniform contact pressure ensured in the arrester active part.
  • a uniform Current density of the occurrence of an overvoltage in the arrester active part Guided arrester current is guaranteed.
  • inadmissibly high levels of local warming occur Arrester active part avoided.
  • the support surfaces 17, 18 substantially circular arc-shaped surface profile.
  • the loop ends then lie with a uniform, relatively small Curvature on the connection fittings 1, 2 on. This will be undesirably large bending and shearing stresses of Loops largely avoided.
  • a rectangular, in particular a square, cross-sectional profile the loop 5 with a relative small width transverse to the axis z is particularly advantageous because then the slit-shaped section 15 or 16 only must be extended slightly over the axis z addition.
  • the connection fitting 1 or 2 then has a high mechanical Strength on.
  • connection fittings 1, 2 are partial, the varistor elements 8, the printing plates 10, 13 and the loop 5 are completely from a shielded cast housing 19 of insulating material, preferably of an elastomeric Silicone, enclosed (Fig.1).
  • connection fitting 2 To make the active part of the series after the connection fitting 2, the pressure plate 13, one of the Current transfer elements 14, the varistor element 8, another Stromübergangselement 14, the pressure plate 10, the two Spring elements 9 and the connection fitting 1 in a template stacked and with a biasing force applied.
  • the connection fittings 1, 2 are doing so aligned such that the two slot-shaped sections 15, 16 congruent superimposed ( Figures 2 and 3).
  • the biasing force is then canceled and the arrester active part is completed.
  • Twisting the pressure screw 4 can additionally contact and Holding force to be generated in the arrester active part.
  • a prefabricated loop can also be a loop used during the manufacture of the surge arrester is formed.
  • the two connection fittings 1, 2 under the formation of contact force firmly clamped together and thereby a mechanically stable active part of the produced Surge arrester formed.
  • a good mechanical Strength of the arrester active part extends this tension in the general already completely off.
  • fiberglass fabricated tape may therefore be used the spring elements 9 omitted.
  • such a band is a prepreg, in particular based on glass fibers and epoxy.
  • a prepreg points a good adhesion effect.
  • prepreg wound loop is also after winding stable without additional fastening device and can then Cured at elevated temperatures. This forms then one of glass fibers and one of the glass fibers embedding, hardened plastic matrix existing loop.
  • connection fittings 1, 2 By bracing the two connection fittings 1, 2 is in addition to a good contact of the individual in the current path between the two connection fittings located parts at the same time a nestling of the grooves of the current transfer elements 14 to the end faces of the varistor element 8 and the Pressure discs 10, 13 reached.
  • insulating material preferably on the base of an elastomeric silicone
