Claims (1)
され絶縁容器中に酸化亜鉛素子を収納した避雷要
素と、この避雷要素下端との間に直列ギヤツプを
保持して前記懸垂がい子装置の充電部側に支持さ
れたアークホーンとを備え、前記絶縁容器が前記
酸化亜鉛素子の故障時に生成する高温ガスを放出
する常時は閉ざされた放出口を有する避雷装置に
おいて、前記絶縁容器の放出口を覆うよう被着さ
れ前記高温ガスの放出をその圧力および熱により
感知して破断する故障検知部と、この故障検知部
により前記放出口近傍に挾持され一方端が避雷要
素に固定されたテープ状の耐熱絶縁材からなり故
障検知部の破断により自由端側が垂れ下がつて故
障を表示する故障表示部とを備えてなることを特
徴とする送電線用避雷要素の故障表示装置。 A series gap is maintained between a lightning arrester element whose upper end is fixed to a power transmission tower together with a suspension insulator device and a zinc oxide element is housed in an insulating container, and the lower end of this lightning arrester element to connect the suspension insulator device to the live part side. a supported arc horn, the insulating vessel having a normally closed outlet for discharging high temperature gas generated in the event of a failure of the zinc oxide element; a failure detection part that detects the release of the high-temperature gas by pressure and heat and ruptures it; and a tape-shaped heat-resistant insulating material that is held near the discharge port by the failure detection part and has one end fixed to the lightning protection element. 1. A failure display device for a lightning protection element for a power transmission line, comprising: a failure display portion whose free end side hangs down to indicate a failure due to breakage of the failure detection portion.
