Claims (5)
- 電気が供給される配線電路に対して電気的接続がなされるように介在させる放電検出装置であって、
配線電路を流れる電気のうち放電事象により生じる所定の周波数以上のノイズ成分のみが通過することができるハイパスフィルタを有し、前記ハイパスフィルタを通過したノイズ成分に基づいて検出信号を出力するノイズ検出部と、
ノイズ検出部から出力された検出信号を閾値と比較して放電事象の有無を判定する演算部と、
放電事象の検出時に、放電検出装置の外部に異常の知らせをする、若しくは、放電検出装置の外部に位置する機器に信号出力をする信号出力部と、
放電事象が検出されたことを記憶する記憶部と、
を備え、
放電事象の発生回数をカウントしない時間であるカウントアップ停止時間の時間計測がなされている間に、検出信号が閾値を超えても、記憶部に記憶される放電事象の検出回数に変化はなく、前記カウントアップ停止時間の時間計測がなされていない間に、検出信号が閾値を超えると、カウントアップ停止時間を開始させるとともに記憶部に記憶される放電事象の検出回数が1つ増加されるように制御され、
前記演算部は、記憶部に記憶された放電事象の検出回数によって、放電検出装置の外部に異常の知らせをするためになされる信号出力部からの出力、若しくは、放電検出装置の外部に位置する機器に信号出力をするためになされる信号出力部からの出力、が異なるものとなるように変更可能である放電検出装置。 - 記憶部で記憶された放電事象の情報のリセットが可能なリセット部を備えた請求項1に記載の放電検出装置。
- 利用者又は他の機器からの情報のインプットにより、信号出力部からの出力を変更させる出力設定部を備えた請求項1又は2に記載の放電検出装置。
- 記憶された放電事象の増加によってLEDの点滅間隔若しくはアラームの出力間隔の少なくとも一方を通常よりも短くすることが可能な請求項1から3の何れかに記載の放電検出装置。
- 前記配線電路から流れてきた放電電流を検出する電流センサを備え、
記憶部が、電流センサで得られた放電電流の計測情報を記憶し、
演算部が、記憶部に記憶された放電電流の情報によって信号出力部の出力を変更する請求項1に記載の放電検出装置。
