Abstract
114,715. British Thomson - Houston Co., (General Electric Co.). June 13, 1917. Electro-magnetic switches.-In voltage regulators in which after the sensitive device such as the voltage coil 9 has moved the contact arm 7 against a fixed contact 6, a reinforcing winding 13 is energized to prevent chattering, a further coil 16 is used, and acts on the same core as the coil 9; the coils 13, 16 and control circuits are supplied with current of frequency different from the main current, the coil 16 compensating for the magnetic interference between the coil 9 and the coil 13. The coil 9 is wound oppositely, with respect to the flux developed by the coil 9, to the coil 13. As applied to an induction regulating device 2, a second fixed contact 5 with reinforcing winding 12 is used; according as the movable arm engages one or other of these contacts, when the voltage departs from the normal, one or other of two coils 25, 26 is energized to move the reversing switch 24 for the three-phase relay motor 3. The coils 13, 16 may be in series or in parallel.
