- 落雷による電線路の損傷の有無を検出する検出器であって、
動作電源を供給する電源供給手段と、
前記電源供給手段によって動作電源が供給される第1および第2のホール素子を有し、前記第1のホール素子が正極性の雷電流に応答し、前記第2のホール素子が負極性の雷電流に応答するセンサ手段と、
前記第1のホール素子および前記第2のホール素子の出力から交流分と直流分とを分別する第1および第2の分別回路と、交流分が大である場合には、交流分の出力により、前記センサ手段の直流分を出力することなくグランドする出力回路とを備えて、前記センサ手段によって検出された雷電流の直流分を出力する判別手段と、
前記判別手段が出力する前記雷電流の直流分に基づいて前記落雷が前記電線路に損傷を与える長波尾雷であるか否かを電流継続時間によって判別し、前記長波尾雷である場合に前記電線路の損傷検出を与える損傷検出手段と、
を有する電線損傷検出器。
- 前記電源供給手段が、
電源電池と、
前記電線路に流れる電流による誘導電圧に基づいて充電される充電手段を有し、前記充電手段の充電電圧によって起動出力を与える起動手段と、
前記起動出力に応答し、前記電源電池に基づく動作電源を所定時間の間前記センサ手段の前記ホール素子に供給する動作電源供給手段と、
を有する請求項1に記載の電線損傷検出器。
- 前記電源供給手段が、
前記電線路に流れる電流による誘導電圧に基づいて充電される充電手段と、
前記センサ手段の前記ホール素子に前記充電手段の充電電圧に基づいて動作電源を供給する定電圧回路と、
を有する請求項1に記載の電線損傷検出器。
- 前記電線路の損傷検出を与える前記損傷検出手段が前記長波尾雷を検出したことを表示する表示装置を備える請求項1に記載の電線損傷検出器。
- 前記センサ手段は、誘導又は地絡故障により電線路に交流電流の流れた際に前記第1のホール素子に前記交流電流のプラス側の応答する出力を付与し、前記第2のホール素子に前記交流電流のマイナス側の応答する出力を付与し、前記第1のホール素子および前記第2のホール素子の出力を共に前記判別手段に付与する構成とした請求項1乃至4の何れかに記載の電線損傷検出器。
- 前記センサ手段が、前記電線路に着脱自在に取付けられて磁路を形成する磁性体からなる保持部材を有し、前記保持部材が前記磁路を開放するギャップに前記ホール素子を保持するようになっていると共に、前記ギャップの間隔を変化させることによって前記ホール素子の感度を調節するようにした請求項1乃至5の何れかに記載の電線損傷検出器。
