Abstract

The invention discloses a phase compound excitation electric generator which comprises a rotor, a stator, a collecting ring, a rotor winding, a stator main winding, a stator auxiliary winding, a composite reactance converter, a rectifier bridge set and an automatic voltage regulator. A phase compound excitation device is composed of the composite reactance converter, the rectifier bridge set and the automatic voltage regulator. The composite reactance converter is composed of an iron core, a primary winding, a secondary winding, an upper yoke iron core and a wiring terminal block which are arranged on a bottom frame. The wire end of the stator main winding is connected with the tail end of the primary winding, the starting end of the primary winding is an output load end, the wire end of the stator auxiliary winding is connected with the starting end of the secondary winding, the tail end of the secondary winding is connected with one end of the rectifier bridge set, the other end of the rectifier bridge set is connected with the collecting ring, and the automatic voltage regulator is connected with the rectifier bridge set, the primary winding and the collecting ring at the same time. The phase compound excitation electric generator has the advantages of being little in material consumption, small in size, low in weight, and wide in application range.

Description

technical field [0001] The invention relates to a generator, in particular to a phase compound excitation generator. Background technique [0002] Generators are divided into two categories: DC generators and AC generators. The latter can be divided into synchronous generators and asynchronous generators. The most commonly used in modern power stations are synchronous generators. Generators are usually composed of stators, rotors, end covers, bearings and other components. The stator is composed of stator core, wire wrap winding, frame and other structural parts that fix these parts. The rotor is composed of rotor core (or magnetic pole, magnetic yoke) winding, guard ring, center ring, slip ring, fan and shaft and other components. The stator and the rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and do the movement of cutting the magnetic force line, thereby generating an induced potent...

Problems solved by technology

[0003] Although the existing phase-compound excitation generators have a certain automatic excitation function and automatically adjust the output voltage of the generator to make the voltage output constant, the linear reactor and the converter must use two sets of iron cores that are close to the same volume. And winding, the consumption of materials is large, and the production process cycle is also long, which affects the improvement of productivity
