Embodiment Construction

[0035] figure 1 A section through the overvoltage arrester 1 is shown. The surge arrester 1 has a discharge path 2 . The discharge path 2 includes a first discharge column 3 and a second discharge column 4 . Other discharge columns are blocked by the first discharge column 3 and the second discharge column 4 . The first discharge column 3 and the second discharge column 4 and the covered discharge column have basically the same structure.

[0036] Now, the structure of the discharge column is exemplified by means of the first discharge column 3 . The first discharge column 3 each has a first and a second fitting 5 , 6 closing the first discharge column 3 at the end sides. The fittings 5, 6 of the first discharge column 3 are connected to each other by anchor rods 7a, 7b. Anchor rods 7a, 7b are fixed in fittings 5, 6. A plurality of varistor elements 8 a , 8 b , 8 c , 8 d , 8 e , 8 f are inserted between the fittings 5 ​​, 6 . The varistor elements 8 a , 8 b , 8 c , 8 d ...

Abstract

A surge arrestor arrangement (1) comprises an arrestor current path (2) with a plurality of arrestor columns (3, 4). The arrestor columns (3, 4) are provided on one side with terminal fittings (5, 6). The fittings (5, 6) are connected together by way of a coupling element (16). It is advantageous that the coupling element (16) can comprise a plurality of branches (17a, 17b, 17c, 17d) that can be formed independently of one another.

Description

technical field [0001] The invention relates to a surge arrester comprising a discharge path with a plurality of discharge columns, wherein at least one first and one second discharge column each have at least one fitting which closes the discharge column at the end. Background technique [0002] Such an overvoltage lightning protection device is described, for example, in the European patent document EP0673543B1. This known surge arrester comprises a discharge path with a plurality of discharge columns. The discharge columns are respectively provided with fittings on the end sides, which close each discharge column. Here, each discharge column is positioned individually by means of individual compression springs. The length difference of the individual discharge columns can be compensated by means of compression springs. [0003] Assembly of this known overvoltage arrester is cumbersome due to the individual positioning of the individual discharge columns. Each discharg...
