Magnetic module for measuring magnetic flux generated by current flow in electrical conductor, has magnetic core made of soft magnetic material, which is wound in sections with multiple turns, through which electrical conductor is passed

摘要

The magnetic module has a magnetic core (21) made of a soft magnetic material, which is wound in sections with multiple turns (2) and a measuring section (3). The multiple turns are designed such that an electrical conductor (1) is passed through the turns. A measuring point is provided in the measuring section for measuring the magnetic flux that is proportional to the current in the electrical conductor. The electrical conductor is partially surrounded by the turns of the magnetic core, while the measuring section has an air gap (4). A magnetic field sensor is arranged in the gap to measure the magnetic flux. The soft magnetic core has a highly permeable nickel-iron alloy, pure iron, iron silicon or silicon iron aluminum.
