Definitions

  • the invention relates to a surge arrester with at least one diverting element which is electrically connected between two conductive end fittings is arranged, and with at least a clamping element attached to both end fittings is and the from the diverter and the end fittings formed stack in the axial direction holds together.
  • Such a surge arrester is for example off Japanese Patent Application JP-A-63 312 602.
  • the present invention is based on the object at a surge arrester of the type mentioned the To simplify assembly and a reliable clamping of the To reach piles.
  • the object is achieved in that the bracing in at least one end fitting in a clamping sleeve is held that the outer contour of the clamping sleeve in the axial direction towards the middle of the stack in a conical Tapered area that the clamping sleeve for Recording a Verspannementss has a bore whose Boundary walls at least in the conical region to the bore interior are movable, and that the end fitting for Recording ever a clamping sleeve a continuous recess in which the respective clamping sleeve under deformation the conical region is at least partially insertable.
  • the bracing element can be attached to the end fitting in inserted the clamping sleeve and this in the continuous Recess be introduced within the end fitting.
  • the pre-assembled stack is then fixed and on the Clamping element is applied a tensile stress.
  • the tensioning element is thus elastically elongated.
  • the spring tension the Verspannements is stored by at least a spacer in the stack the Verspannweg balances.
  • Such a spacer can, for example by one between an end fitting and the diverting elements movable spacer screw be realized.
  • the clamping sleeve can so far in the continuous recess of the end fitting be inserted, that the conical portion of the clamping sleeve to the walls of the through recess of the End armature abuts so that the boundary walls begin, to move radially to the bore interior on the Verspannelement.
  • the conical region of the bracing sleeve continues deformed and the boundary walls become radially inward pressed on the Verspannelement.
  • KraftSchluß held the bracing in the bracing.
  • the conicity of the clamping sleeve is also suitable to train.
  • the bracing element advantageously consists of a fiber-reinforced Epoxy resin. Due to the radial force in the Clamping element by means of frictional connection to the clamping sleeve on the one hand, there is no notch effect on the bracing element, on the other hand, almost the entire cross section used the Verspannements for transmitting the axial force. Due to the axial tension of the stack holds the bracing in the bracing automatically.
  • the continuous recess in the end fitting to the conical portion of the clamping sleeve is formed complementary.
  • clamping sleeve slotted in the conical area so that the boundary walls the bore in the conical region radially are resiliently movable.
  • a further advantageous embodiment of the invention provides in that the clamping element in each of the end fittings by means of a clamping sleeve is held.
  • end fittings protrude radially over the diverting and in the projecting area conical holes for receiving the respective Have Verspannhülsen
  • each clamping sleeve has a bore whose shape is in register with the outer contour adapted to the respective Verspannementss.
  • Figure 1 shows schematically the surge arrester with a Stack consisting of the diverting elements 1,2,3 and the end fittings 4,5 exists.
  • the diverting elements are for example made of zinc oxide.
  • Each diverting element is at its end faces metallized, so that by axial compression of the end fittings 4,5 and the diverting 1,2,3 a conductive connection exists between the diverting elements.
  • leakage d. H. if the voltage applied to the surge arrester has a exceeds critical value, then a leakage current from the an end fitting 4 via the diverters 1,2,3 to the other End fitting flow.
  • the bracing elements 6,7,8 provided as in cross-section circular rods of fiber-reinforced Epoxy resin are formed.
  • the reinforcing fibers may be, for example, glass fibers.
  • clamping elements 6,7,8 each in one Clamping sleeve 9,10,11,12,13,14 held.
  • each bracing sleeve is hollow cylindrical formed and has a conical region 15, the tapered axially towards the center of the stack.
  • the bracing sleeve 9 has a bore 20 in its interior on, the exact fit to the outer contour of a clamping element. 6 is adapted.
  • the bracing sleeve 9 In the conical region 15 are continuous slots 16,17,18,19 provided in the bracing sleeve 9, through which the Boundary walls 21,22,23,24 of the through hole 20 in the conical region 15 radially with respect to the longitudinal axis the bracing sleeve 9 are resiliently movable.
  • Each of the end fittings 4,5 has recesses in the form of conical Holes, each of which a clamping sleeve 9,10,11,12,13,14 absorbs.
