Description
Claims (5)
- 架空配電線の長さ方向に所定の長さで前記架空配電線の周囲を包囲して前記架空配電線の一部を被覆するための防護管本体と、前記防護管本体の長手方向に沿わせて閉回路を形成し前記防護管本体で被覆された部分の架空配電線に流れる電流により誘導起電力を誘起させる誘導起電力誘起部とを備えたことを特徴とする架空配電線防護物。
- 前記誘導起電力誘起部は、前記防護管本体の長手方向に沿わせて前記防護管本体の外面に取付部により着脱可能に取り付けられた閉回路導体であることを特徴とする請求項1記載の架空配電線防護物。
- 前記誘導起電力誘起部は、前記防護管本体の長手方向に埋め込まれて形成された内部導体と、前記内部導体に差し込みソケット状に形成された取付部により着脱可能に取り付けられ閉回路を形成する外部導体とからなることを特徴とする請求項1記載の架空配電線防護物。
- 前記誘導起電力誘起部は、前記防護管本体の外周面に着脱可能に装着される1個の環体であることを特徴とする請求項1記載の架空配電線防護物。
- 請求項1乃至請求項4のいずれか1項記載の架空配電線防護物を電気量測定対象の架空配電線に取り付け、前記各配電線防護物の誘導起電力誘起部に誘起された誘導起電力に基づく電気量を検出する電気量検出部を前記誘導起電力誘起部に取り付け、前記電気量検出部に計測部を接続し、前記計測部により前記電気量検出部で検出された電気量に基づいて状態判定を行うと共に電気量を計測することを特徴とする架空配電線監視方法。
