SYNCHRONOUS ELECTRIC GENERATOR WITH MULTIPLE SLIP-RINGS AND SEPARATING EXCITATION WINDINGS

The utility model relates to a synchronous electric generator with multiple slip-rings and separating excitation windings. On the basis of traditional synchronous generators, the utility model separates the excitation windings of the generator rotor into two sets, two pairs of slip-rings respectively extracted are segregated and connected in series with two sets of thyristor converters of the excitation power supply, and then symmetrically connected to ground through high value resistors, and so the highest potential to ground of the entire excitation system is only one quarter of the loop total voltage. The two sets of thyristor converters are reserved for each other, and in the high top value and strong excitation the two sets of converters are both threw in. The utility model is practicable for the large-sized synchronous generator with the high top value, rapid response and strong excitation operational characteristics and the synchronous generator with the phase modulation operation requirement.
