SUSPENSION DEVICE FOR LINE-MOUNTED SURGE ARRESTER

摘要

A suspension device for a line arrester (14) in an air-insulated transmission line comprising two suspension parts (15, 16) which support the line arrester (14) such that its longitudinal axis deviates from the vertical line, wherein one of the suspension parts (15 or 16) comprises a disconnecting device (17) which, when releasing, permits the line arrester (14) a swinging motion under the influence of a force of gravity caused by the weight of the line arrester itself, and wherein one of the suspension parts (15 or 16) comprises a damping member (19) which influences the line arrester (14) with a force directed against the swinging motion during at least part of the swinging motion. The damping member may comprise a damping plate, one or more friction linings or a flexible wire.
