Abstract

The great-capacity single-phase brush-less synchronous generator has new-type superposed single-layer equal-turn single-phase sinusoidal winding; double-cage damping rotor system with less produced heat and excellent effect; specially designed exciting winding with powerful excitation capacity; and voltage regulator with sensitive load property identification, feedback and voltage regulating functions. The present invention makes it possible to develop great-capacity single-phase generator and to provide single-phase power supply with excellent electrical performance.

Description

technical field [0001] The patent of the present invention relates to power supply equipment, in particular to a large-capacity single-phase brushless synchronous generator. Background technique [0002] In addition to the working synchronous rotating magnetic field, the single-phase synchronous generator also has a so-called reverse-sequence rotating magnetic field. This reverse-sequence magnetic field is used as an excitation source in a small synchronous generator. The so-called reverse-sequence magnetic field excites the generator. This kind of generator often has poor voltage waveforms, sensitive frequency effects, and unsatisfactory power generation quality. In a single-phase brushless generator with an AC exciter, the reverse sequence magnetic field increases the temperature rise of the rotor and reduces the efficiency. In a large-capacity single-phase brushless generator, the energy of the reverse-sequence magnetic field is very large, which will cause a large amoun...
