Abstract

PURPOSE: To detect the flow of working current in or the application of working voltage to a primary coil when current or voltage is induced in a secondary coil by the displacement of an iron core in the primary coil.
CONSTITUTION: A nonmagnetic pipe 2 fixed to a yoke 1 contains a movable iron core 3, a spring 4 pressing the core in its reversing direction and oil 5 for braking. If working current flows in or working voltage is applied to a primary coil 6 outside the nonmagnetic pipe 2, the movable iron core 3 moves forward in the primary coil overcoming the force of the spring 4, magnetic resistance decreases suddenly and detecting current or voltage is induced in a secondary coil 7. The time from the application of working current or voltage to the primary coil to the induction of detecting current or voltage in the secondary coil can be adjusted by the strenfth of the braking force of oil 5. By making the braking force zero, immediate detection can be realized.
