Claims (1)
持金具により絶縁電線を支持固定しその碍子体を同碍子
体に固着したピンによりアース側の腕金に取付固定して
なる高圧配電線路における絶縁電線の支持装置において
上記支持金具の末端の近傍の絶縁電線には同電線に対し
外周面を絶縁モードしてなる電圧非直線性を有する限流
素子を取り付け、而も同素子の一方の端面に溶接する充
電側電極を上記絶縁電線の芯線に電気的に接続し、また
同素子の他方の端面に密接する非充電側電極を上記支持
金具に対し若干の絶縁距離を保って対向させると共に、
さらに上記限流素子の外周を覆うように上記絶縁電線に
対し密着して気密的に取り付けた絶縁カバーには上記支
持金具と非充電側電極との間に介在する中間電極を設け
たことを特徴とする絶縁電線の断線防止装置。In a high-voltage distribution line in which an insulated wire is supported and fixed to the head of an insulator by a support fitting such as a bind wire or a wrap grip, and the insulator is fixed to a arm on the ground side using a pin fixed to the insulator. In the insulated wire support device, a current limiting element having voltage nonlinearity is attached to the insulated wire near the end of the support fitting, and the outer peripheral surface of the wire is in an insulating mode, and a current limiting element having voltage nonlinearity is attached to one end surface of the element. A charging side electrode to be welded to the insulated wire is electrically connected to the core wire of the insulated wire, and a non-charging side electrode that is in close contact with the other end face of the element is opposed to the supporting metal fitting with a slight insulation distance,
Furthermore, an insulating cover that is airtightly attached to the insulated wire so as to cover the outer periphery of the current limiting element is provided with an intermediate electrode that is interposed between the support fitting and the non-charging side electrode. Disconnection prevention device for insulated wires.
