Abstract:
1. Surge arrester comprising at least one arrester element ( 2 ), and a disconnection device for disconnecting the arrester element(s) ( 2 ) from line power, wherein the disconnection device comprises a thermal point of separation (c) which is incorporated into the electrical connection path within the arrester, wherein a movable conductor section or a movable conductive bridge ( 3 ) is connected by means of the point of separation (c) to the arrester element ( 2 ) on the one hand, and the conductor section or the bridge ( 3 ) is connected to a first external electrical connection (A) of the arrester on the other hand, and comprising a means for generating a preload force, wherein a force vector associated therewith acts directly or indirectly on the conductor section or the bridge ( 3 ) in the disconnecting direction by means of a movable disconnecting component ( 13 ), wherein further a conductive element (b) is disposed in or at the end of the path of the movement of the conductor section or the bridge ( 3 ), which comes into contact with the conductor section or the bridge ( 3 ) when the disconnection device is released, and which is connected to a second external electrical connection (B) for forming a short-circuiting device; wherein a movable insulating part ( wherein the movable disconnecting component ( wherein the disconnecting component with the insulating part (
