Simistornij Regulyator Napryazheniya Dlya Induktivnoj Nagruzki

Raskroj kuznecova keygen. This book, 'Materialy dlya izucheniya ekonomicheskogo byta gosudarstvennyh krestyan i inorodtsev Zapadnoj Sibiri Vypusk 4,' by D.I. Bagalej, is a replication of a book originally published before 1889. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.

FIELD: electrical engineering. SUBSTANCE: device is, essentially, three-circuit automatic control system depending for its operation on slave control of coordinates. First slave circuit controlling field current incorporates current regulator, controlled thyristor valve, and current sensor. Second slave circuit controlling reactive current of synchronous motor includes reactive-current measuring transducer and reactive-current regulator; it functions to maintain stator reactive current at level set by voltage regulator output signal. Third one is main voltage-control circuit incorporating voltage measuring transducer and voltage regulator. Voltage feedback including threshold element, one-shot multivibrator, first aperiodic filter with controlled time constant, two Schmitt flip-flops of aperiodic filter and AND gate functions to raise field current setting value in case of heavy voltage fluctuations to ensure steady operation of motor.

EFFECT: improved reliability of voltage control and reduced power loss in motor and in supply mains. 2 dwg Description Translated from Russian.
