Claims (1)
- 電路に流れる電流を検出する電流検出手段と,該電流検出手段から出力される電流値を電流電圧変換手段にて電圧値に変換した電圧信号により,プラグのトラッキング現象による短絡や絶縁劣化によるコード短絡の発生を判定するプログラムを予め記憶させたマイコンを内蔵した判定手段と,該判定手段の出力により駆動する引き外し手段と,該引き外し手段の駆動により電路を遮断する開閉手段と動作確認手段を備えた回路遮断器において,動作確認手段は,テストボタンと,前記マイコンの駆動電圧を利用することにより,コード短絡時に電流検出手段から出力される電流値に相当する電圧であって,前記マイコンに記憶されたコード短絡を検出するためのプログラムの判定条件に合う電圧を生成する分圧抵抗を前記マイコンに接続して構成し,テストボタンを押圧すると,前記分圧抵抗で生成されたプログラムの判定条件に合う電圧が,電流検出手段を介さずに前記判定手段のマイコンに入力されることにより,回路遮断器における判定手段,引き外し手段,および開閉手段の動作確認を行うことを特徴とした回路遮断器。
