- 変圧器に取り付けられ、特定周波数の電磁波の発生を伴う部分放電を検出し、前記部分放電に関する情報を異常判定装置へ転送する、部分放電検出装置であって、
前記変圧器およびその近辺の探査対象領域における部分放電発生源の種類に応じた様々な特定周波数の電磁波を受信する放電検出アンテナ、
放電検出アンテナによって受信された前記特定周波数における電磁波の受信電圧を検出する受信電圧検出手段と、前記受信電圧と予め設定された閾値電圧とを比較する比較手段とを有し、前記受信電圧が前記閾値電圧よりも大きくなったときに放電パルス検出信号を出力する放電パルス検出手段、
前記放電パルス検出信号が出力された時点の日付時間情報を記憶するメモリ、および
前記メモリに記憶された前記日付時間情報を異常判定装置へ転送する転送手段を備えると共に、
前記探査対象領域における電磁波を中波帯域において受信する探査アンテナ、および
前記探査アンテナで受信された放電パルスを含む所定値以上の電圧の電磁波によって誘導起電力を発生させ、その誘導起電力によって電源をONする電源ON手段をさらに備える、部分放電検出装置。 - 前記放電パルス検出信号が所定時間出力されないときに電源をOFFする電源OFF手段をさらに備える、請求項1記載の部分放電検出装置。
