Jiangsu Starlight Dynamic Get TFW Generator Excitation Conflux

The utility model relates to a TFW brushlessgeneratorThe exciting constant current device, the input sampling voltage filtering amplifier is connected to the generator three-phase winding, which is compared to the amplifying circuit, the shift trigger circuit, and the excitation stream output circuit excitation output, the controllable silicon rectifier circuit of the excitation magnetoon output circuit and Overcap current collecting circuits are connected to differential amplifiers and delay integral circuits, and the overflow current setting circuit connection compare the amplifying circuit, the differential amplifier is connected to the generator excitation winding, and the delay integration circuit is connected to overcurrent output comparison And delay integral circuits. The additional overcurrent current setting circuit can monitor the change in generator load current, and the size of the excitation current can be adjusted in real time to keep the generator output voltage unchanged. It has the advantages of stable operation, high reliability, constant current protection current.
