【実用新案登録請求の範囲】[Scope of utility model registration request] 絶縁体の両端にライン側電極およびアース側電極を有す
る避雷器本体の外周に沿って前記両電極を短絡するため
の導電片を配置し、この導電片と避雷器本体との間に該
導電片を両電極の少くとも一方から離間させるべく低融
点ペレットを介在させるとともに、前記避雷器本体の外
周に、前記導電片を避雷器本体に向って付勢しかつ前記
低融点ペレットが溶けた際に導電片を離間した電極に対

設けたことを特徴とする短絡機構付避雷器。A conductive piece for short-circuiting the two electrodes is arranged along the outer periphery of the arrester body which has a line side electrode and a ground side electrode at both ends of the insulator, and the conductive piece is placed between the conductive piece and the arrester body. A low melting point pellet is interposed to separate it from at least one of the electrodes, and the conductive piece is urged toward the arrester body on the outer periphery of the arrester body, and when the low melting point pellet melts, the conductive piece is separated. 1. A lightning arrester with a short-circuiting mechanism, characterized in that a substantially C-shaped spring body is provided so as to hug the electrode.
