Definitions

  • Surge arresters are protective systems, for example for power transmission networks, which in case of overvoltages caused by lightning strikes or malfunctions of other subsystems dissipate these overvoltages to ground and thus protect other components of the power transmission system.
  • Such a surge arrester comprises one or more cylindrical Ableit yarnlen of individual also cylindrical Varistorblöcken.
  • Varistors are characterized by a voltage-dependent resistor. At low voltages these act as insulators. From a certain threshold voltage, which is material-dependent, they show a good conductivity. Frequently, varistors are made from metal oxides such as zinc oxide. The discharge column is connected at both ends with end fittings, which establish the electrical contact to the power line and to ground. In order to ensure a good electrical contact between the varistors, even under mechanical stress, the Ableit yarn must be held together by an axial contact force.
  • a surge arrester having a diverter column with an active part is known, which is axially and radially supported by elastic reinforcing elements and held together by an axial contact force inter alia by means of central screws mounted in the fittings.
  • An insulation shield is provided for insulation of the arrester column and tension loops. The tensioning loops are used to increase the flexibility of pre-assembled elements to avoid breakage of the construction.
  • the object of the invention is to provide a surge arrester, which is easy to assemble and allows a few variants a large variety of variants. Another task is to have a most efficient method of assembly to specify a surge arrester.
  • the solution of the problem concerning the surge arrester is achieved by a surge arrester having the features of claim 1.
  • a surge arrester has a preassembled active part having a discharge column, which is in a rigid, is arranged along a longitudinal axis extending tubular housing.
  • the longitudinal axis defines an axial direction.
  • the rejection column is preferably constructed of a plurality of cylindrical varistor blocks stacked in a column along the longitudinal axis.
  • the active part is clamped between two flanges closing the housing on the front side.
  • the preassembled active part has an upper and a lower retaining plate, one of which rests on the upper and one on the lower end side of the Ableit yarn.
  • the terms "upper / upper” and lower / lower are for distinction only and do not represent a reference to a spatial orientation.
  • Between the holding plates extends the Ableit yarn.
  • Each holding plate has at least two, preferably four, cams which preferably extend parallel to the longitudinal axis from a side of the holding plate facing away from the delivery column.
  • the delivery column is held together axially by at least two elastic tensioning loops and is radially supported by tensioning each tensioning loop between a cam of the upper holding plate and a corresponding cam of the lower holding plate.
  • the pre-assembled active part thus consists of the delivery column, the holding plates and the tension loops.
  • Such a pre-assembled active part is sufficiently stable for the purpose of assembly.
  • the necessary contact force is not applied by the tension loops. This is achieved only by the bracing between the flanges.
  • the straps can be easily stretched by hand.
  • the assembly is considerably simplified.
  • the radially closest to the longitudinal axis point of a cam defines a deflection point for the tensioning loops.
  • the retaining plate includes first segments S 1 with a radius R 1 and second segments S 2 with a radius R 2, where the Ableit yarn has a radius R A and wherein R2 ⁇ R A ⁇ R 1, and wherein the deflection point a distance R u ⁇ R 2 from the longitudinal axis. All radii are in a plane perpendicular to the longitudinal axis measure up.
  • the circumferential line of the holding plate thus has segments with different radii, preferably per clamping loop, a segment S 1 with a larger radius R 1 and a segment S 2 with radius R 2 .
  • the rejection column can assume radii R A between R 1 and R 2 .
  • the segments S 1 serve to support the holding plate as wide as possible on the delivery column.
  • the deflection point set back relative to the outer contour in the direction of the longitudinal axis, which also forms the central axis, ensures that the tensioning loops extend at least partially in the radial direction at their ends. If they are stretched, a radial force component acts there, which additionally stabilizes the deflection column.
  • each tensioning loop runs from the deflection point through a second segment S 2 to the shell side of the delivery column.
  • the same holding plate for Ableit yarn with diameters of R 2 to R 1 are used, which reduces the stock to be held variant variety of retaining plate
  • the clamping loops are then axially along the shell side of the Ableit yarn, and are at the transition of the shell side to the front page Ableit yarn deflected toward the cams out at least partially extending in the radial direction, which the Ableit yarn when the tensioning loops are stretched, again radially supports.
  • the Ablesit yarn at their end faces in each case an end plate with at least one rounded edge, wherein the tensioning loops extend over the rounded edge.
  • the end plates are circular cylindrical plates of a few millimeters in thickness and a diameter corresponding to that of the varistor blocks used, made of an electrically conductive material such as steel or aluminum, in which the circular edge is rounded at the transition from shell side to the front side.
  • the radius of curvature is preferably at least 0.5 mm and may be up to half the thickness of the end plate.
  • the end plate distributes the pressure which the holding plates exert on the delivery column evenly over the mostly very brittle varistor blocks, on the other hand
  • the rounded edges protect the clamping loops, which do not run over the mostly sharp edge of the varistors.
  • the tension loops preferably have a volume resistance and a surface resistance of at least 10 6 ohms, preferably at least 10 9 ohms. This ensures that below the threshold voltage no significant currents flow through the tensioning loops.
  • clamping loops on a circular cross-section are available in many lengths and easy to handle.
  • the tensioning loops made of an elastomer, preferably made of natural or synthetic rubber, such as silicone.
  • an elastomer preferably made of natural or synthetic rubber, such as silicone.
  • this offers the best elastic properties for the present application; on the other hand, such tensioning loops, for example as commercially available O-rings, are particularly readily available and cost-effective.
  • At least one of the retaining plate has a centering pin which can be inserted into a centering device on the flange.
  • a centering device on the flange for example, a centering plate with a corresponding bore or a spiral spring can serve with a corresponding central opening.
  • an active part is first preassembled in this method for mounting a surge arrester.
  • a discharge column extending along a longitudinal axis is arranged with its end faces between an upper and a lower holding plate.
  • At least two straps are each stretched between a cam of the upper holding plate and a corresponding cam of the lower holding plate and thus hold the active part axially, ie in the direction of the longitudinal axis, together and support it radially.
  • the thus pre-assembled active part is introduced into a rigid tubular housing in the direction of the longitudinal axis and compressed therein by an external acting on the retaining plate pressing device for generating an axial contact force.
  • the active part is locked in the compressed position by means of a locking device in the housing. The opposing force acting against the contact force is thus absorbed by the housing.

About this, the contact force is transmitted from the housing 2 to the active part 20. At least the outermost turn of the spring 18 is supported on the cover plate 23 at a shoulder of the flange 5 from.
