This invention discloses a two-way frequency conversion brushless synchronous generator composed of IF generator (400Hz), industrial generator (50Hz), AC exciter rotary rectifier, brushless throw-in excitation device, a clutch, a fan, a base, a front cover, a black cover and bearing which is a 50Hz generator using external electricity to operate in asybchronous start, synchronous throw-in excitation, synchronous openation, to drive the generator of another frequency (400Hz) in a completel brushless oparation to realize brushless two-way and conversion generation, cancelling silp-ring brush without spark high frequency interference nor slip-ring and carbon brush wear-out no mutual interference with IF and industrial frequency.
Description
technical field [0001] The invention relates to a rotating power supply, in particular to a double-frequency variable-frequency brushless synchronous generator. Background technique [0002] The dual-frequency variable frequency brush generator has been developed and used since the 1970s, and it has been 30 years. This kind of generator has a brush structure, with slip rings and brushes, sparks are generated during operation, and radio interference Large, easy to slide and wear, difficult to maintain and repair, large excitation current, large and complex excitation system controller, difficult to realize automatic control. The market urgently needs dual-frequency variable frequency generators to achieve brushless, to meet the requirements of intelligent automatic control of power stations. Single-frequency brushless generators are usually composed of main generators and exciters, dual-frequency generators are composed of two-frequency generators, and variable-frequency gen...
