Abstract
281,680. Doloukhanoff, M. Jan. 4, 1926, [Convention date]. Divided on 263,884. Regulation, automatic. -An electric transformer comprises a number of primary coils and a number of secondary coils, both groups being connected to a drum controller with means such such as a voltmeter, ammeter or wattmeter for grouping the coils automatically according to load conditions. As shown, transformer primary and secondary winding P<4>, O<1>-4 and connected to drum controllers C<2>, C<1>, the controllers being under tension from the motor G. The shaft F of the controllers is provided with cams j<1> - - j<4> which engage with stops S<1> - - S<4> energized by solenoids T<1> - - T<4> from the contact-making ammeter M in the transmission line. The controllers have a no-load position in which small primary and secondary magnetizing coils R, Q are in circuit, these coils being cut out. on load.
