SEISMIC UNIT AND DISTRIBUTION BOARD INCLUDING THE SAME

PROBLEM TO BE SOLVED: To provide a seismic unit capable of with little restriction in installation direction, and a distribution board including the same.SOLUTION: A seismic unit 1 includes: an acceleration sensor 11 for measuring acceleration; a signal processing part 10 for processing a measured value from the acceleration sensor 11; and a body 15 for housing the acceleration sensor 11 and the signal processing part 10, which is attached to an attachment part. The signal processing part 10 calculates initial installation direction of the body 15 on the basis of the measured value by the acceleration sensor 11. The signal processing part 10 detects occurrence of earthquake on the basis of the initial installation direction of the body 15 and the measured value by the acceleration sensor 11.SELECTED DRAWING: Figure 1 【課題】取付方向の制約を少なくできる感震ユニット、及びそれを備える分電盤を提供する。【解決手段】感震ユニット１は、加速度を測定する加速度センサ１１と、加速度センサ１１の測定値を処理する信号処理部１０と、加速度センサ１１及び信号処理部１０を収納して被取付部位に取り付けられる本体１５と、を備える。信号処理部１０は、加速度センサ１１の測定値に基づいて本体１５の初期の取付方向を求める。信号処理部１０は、本体１５の初期の取付方向と、加速度センサ１１の測定値とに基づいて地震の発生を検知する。【選択図】図１
