Relay, in particular for high voltage use

摘要

The relay (10) has a movable armature permitting or interrupting current flow via two main contact terminals (16.1, 16.2) by a magnetic flux generated in a coil. A current-measuring instrument measures current flowing via the main contact terminals by a Hall sensor. An aligning device (20) aligns the magnetic flux with the hall sensor around the main contact terminals. The aligning device comprises a ferromagnetic body that surrounds the main contact terminals and provided with a free space for the hall sensor. The ferromagnetic body is made of ferromagnetic metal sheets.
