CURRENT SENSOR HAVING A MAGNETIC CIRCUIT WITH AN AIR GAP

摘要

The magnetic circuit (1) is made in a single piece or consists of a stack of identically-shaped sheets. The height (H) of the air gap (2) is greater than the thickness (E) of a coil (5), enabling said coil to be inserted through the air gap. This structure is easily assembled during the mass production of current sensors which use such circuits.
