Abstract:
A gas-filled surge arrester, comprising:at least two electrodes; an insulator arranged between the electrodes; and an overload fuse, the overload fuse including an external short-circuit device, the short-circuit device including a first short-circuiting link, a holding device and a spacer, the first short-circuiting link being electrically conductive and extending in an axial direction of the surge arrester, ends of the short-circuiting link being held at a radial distance from the electrodes by the holding device, the holding device exerting a spring force via the spacer, the spacer melting when heat is applied, the holding device including an open ring that can be snapped onto the insulator and being made of a strip-shaped resilient material, the first short-circuiting link being arranged on one end of the holding device, the spacer being arranged between a center portion of the first short-circuiting link and the insulator and being out of contact with all electrodes.
