Abstract
100,892. British Westinghouse Electric & Manufacturing Co., (Assignees of Smith, B. H.). July 12, 1915, [Convention date]. Induction relays; protective arrangements.-To increase the range of the time-element of timelimit relays of the induction-motor type for protecting electric circuits, the magnet core of the relay has a main winding 7 energized by the secondary of a transformer 5 in the circuit to be protected, and a secondary winding 8 in series with the primary 25 of the easily saturated small transformer 26 and in series also with auxiliary windings 9, 10, connected in parallel with one another and arranged upon the poles 16, 17 of the core. The secondary 27 of the transformer supplies other auxiliary windings 11, 12 arranged on the poles 16, 17 and opposing the windings 9, 10. Under the influence of the windings described, the armature 13, which is arranged between the magnetizable member 15 and the pole-pieces and is restrained by the spring 19 and the magnetic brake 18, develops a constant torque, with a large time-element. The relay completes at 22 a local circuit containing a battery 24; which operates the main cut-out 3.
