Definitions

  • the invention is based on a surge arrester the introductory part of claim 1.
  • the invention relates to a prior art as it is EP 0 614 198 B1 results.
  • One described in this prior art Surge arrester contains two connection fittings and one between the Connection fittings made of stacked columns Varistor. Electrical contact between the connection fittings and the varistor elements are generated by two or more insulating material loops, the ends of which are each mounted in one of the two connection fittings, and which the two connection fittings and thus also the in between Apply varistor elements with contact force.
  • a surge arrester is known with a Weatherproof housing, two connection fittings led out of the housing and an axially symmetrical active part, which - between the Connection fittings arranged - is located inside the housing.
  • the active part is formed by several cylindrical modules, like a column are stacked on top of each other. Each module has several along the cylinder axis with their end faces lying on top of each other, cylindrical varistor elements. Electrical contact between the varistor elements is ensured by a predominantly axially guided thread winding, which two the module Metal end parts delimiting the end face are subjected to pretensioning force.
  • the End parts of adjacent modules are connected to each other by means of a screw bolt galvanically connected.
  • the object of the invention is as set out in the claims based on a surge arrester of the type mentioned create, which is simple and inexpensive even with a large overall height Way can be made.
  • the surge arrester according to the invention stands out comparable surge arrester according to the prior art from that it is practical with any height in simple and economical Way can be manufactured. It is only added to the arrester active part at least one between two successive varistor elements arranged connecting element made of electrically conductive material suitably trained and arranged bearing points installed on the Storage loops are held in opposite directions guided and at storage points of the connection fittings or another Connecting element or two further connecting elements with formation determined by contact force.
  • the mechanical stability of the active part can be reduced during stacking successive bracing of successive partial stacks can be achieved, wherein the biasing force through in the fittings and / or the connecting elements integrated clamping devices is achieved or by Spring elements that are installed in the stack formed in the template and when attaching the loops the desired contact force and thus also apply the necessary mechanical stability.
  • An additional clamping device can or additional spring elements can be saved if the loops are each elasticized deformable tape, such as glass fibers, are formed.
  • the surge arrester shown in the single figure has one axially symmetrical housing 1, in which along the not designated housing axis an axially symmetrical arrester active part 2 is arranged.
  • the housing is formed by a screened one Insulating tube 3 made of a weatherproof material, for example polymeric material, such as a silicone, or a porcelain and two metal connection fittings attached to the front of the insulating tube 4 and 5.
  • the connection fittings 4, 5 each have a housing 1 gastight, not designated for reasons of clarity Metal plate on and in each case a cylindrical end part 6 or 7, which is arranged axially symmetrically inside the housing 1 and that Lock arrester active part 2 upwards or downwards.
  • In the final part 6 or 7 is a bore provided with an internal thread.
  • the arrester active part is designed as a stack and contains next to the two End parts 6 and 7 also cylindrical varistor elements 12 nonlinear resistance material, such as based on metal oxide, such as in particular of ZnO, and cylindrical metals Connecting elements 13.
  • cylindrical varistor elements 12 nonlinear resistance material such as based on metal oxide, such as in particular of ZnO
  • cylindrical metals Connecting elements 13 In the arrester active part 2 there are further pressure plates 10 ', 11' and disk-shaped current transition elements 14 provided which between a pressure plate 10, 10 ', 11, 11' and a adjacent varistor element 12, between adjacent varistor elements 12 and between a connecting element 13 and a varistor element 12 or a printing plate can be arranged.
  • loops made of insulating material are designated, which preferably from a wound, fiber reinforced and into a polymer matrix embedded band are formed and which two connecting elements 13 or the end part 6 and that in the arrester active part 2 adjoins the part 6 connecting element 13 or the end part 7 and that in Discharge active part 2 connecting part 13 adjoining part 7 brace to form contact force.
  • the loops 15 are with their Ends in grooves 16, 16 ', which in the lateral surfaces of the end parts 6, 7 and the connecting elements 13 are molded.
  • the end parts 6, 7 or the connecting elements 13 protrude beyond the pressure plates 10, 10 ', 11, 11' and Varistor elements 12 in the radial direction.
  • Each of the two connecting elements 13 has six in each case by approximately 60 ° in Grooves 16, 16 'arranged offset from one another in the circumferential direction.
  • This Grooves all have a semicircular opening that is open in the axial direction Section in which one end of one of the loops 15 is mounted.
  • To the semicircular section two close mainly in the axial Direction led sections, in each of which a part at the end of the stored loop, followed by a straight line Loop section is held. This section runs parallel and with predefined dielectric distance from that of the stored Loop with contact force on varistor elements.
  • the straight sections of the grooves 16 run in opposite directions the corresponding sections of the grooves 16 '.
  • the size of the Contact force is caused by twisting when installing the surge arrester the pressure screw 8 and thus by axially displacing the pressure plate 10 set.
  • One of three loops is supported in each of the grooves 16, which the two connecting elements 13 and those arranged between them Varistor elements clamped to form contact force.
  • the contact force will achieved by elastically deformable loops, and can if Desired by a built-in in the connecting element 13 Clamping device with a pressure screw and a clamping plate in it Size can be varied. If necessary, 13 can still in the connecting elements a second clamping device can be installed, which on top of it Section of the arrester active part 2 acts. Clamping screw 8 and pressure plate 10 are then unnecessary.
  • the grooves 16 and 16 ' follow in the circumferential direction of the connecting elements 13. take turns.
  • the pre-tensioning force absorbed by the loops is transferred evenly to the varistor elements 12.
  • the grooves 16 'of the end part 7 and 16 of the Connecting element 13 are aligned so that they are together aligned.
  • the arrester active part can be replaced by further partial stacks extended and finally be completed by the end part 6.
  • the active part can now be inserted into the housing 1 and filled afterwards be closed with a hardenable insulating agent. Because here the loops with Distance from the varistor elements 12 are attached, that encloses Isolierstoff the active part with great security gap and voids free. Therefore points the surge arrester according to the invention, despite any height only good mechanical properties, but also good electrical properties.
  • the housing does not necessarily have to contain insulating material, it can be metals. Then are between the housing wall and the arrester active part additional potential-controlling agents and on the front of the housing Provide bushings.
