| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a current sensor which has a shape that does not surround an electrical cable and thus can be installed in places where electrical cables are arranged close to each other, and which features a reduced number of parts and enables highly accurate current measurement.SOLUTION: A current sensor is configured to contactlessly measure current flowing through an electrical wire, and includes two magnetic sensor modules which comprise insulating members and are accommodated in a frame to be fixed onto the electrical wire and arranged at different distances from the center of the electrical wire.
【課題】電線の周囲を囲うことなく電線相互が近接している場所への設置が可能な形状であり、部品点数を削減できるとともに高精度の電流測定が可能な電流センサを実現すること。【解決手段】電線に流れる電流を非接触で測定するように構成された電流センサにおいて、絶縁性部材よりなり前記電線に固定されるフレーム内に収納され、前記電線の中心から異なる位置に配置された２つの磁気センサモジュールを含むことを特徴とするもの。【選択図】 図１ |
