Three-phase brushless synchronous generator excitation system are connected by a coaxial communication issue of ac exciter,after rotating rectifier rectifier for direct current (dc), Then sent to the generator exciting winding. Ac exciter is rotating armature type of three-phase medium frequency generator,the gasoline generator spare partsfrequency of three phase generator generator frequency three times Left and right sides,which can wholesalemotor.blogspot.com improve the excitation response speed. Exciting winding is stationary,controlled by the automatic voltage regulator AVR excitation. Rotating rectifier Have high reliability,using the three-phase half wave bridge rectifier and three-phase full-wave bridge rectifier,firmly fixed on the rotor,with the current measurement And fault indicating device.
