Abstract
The invention discloses a single-armature electric harmonic excitation six-phase synchronous generator, which is characterized in that a motor stator is internally provided with three windings with the first one being three-phase synchronous motor winding A', the second one being six-phase synchronous generator winding A and the third one being harmonic winding B, and a motor rotor adopts a salient pole structure, and a punching sheet of the motor rotor, as a salient pole integral punching sheet, is composed of large teeth and small teeth. The single-armature electric harmonic excitation six-phase synchronous generator has the advantages that: the generator adopts the single-armature stator structure without being driven by other devices, and outputs six-phase alternating current required by UPS (uninterruptible power supply) and other loads in case of the connection with three-phase mains supply, thereby simplifying the manufacturing process of power generator unit, lowering the manufacturing cost and enhancing the reliability of power generator unit.
Description
Technical field
The present invention relates to a kind of synchronous generator, the electronic harmonic excitation six synchronised generators of especially a kind of single pivot.
Background technology
Generally, synchronous generator is by internal combustion engine, or motor driven, and synchronous generator is moved under rated speed, thereby provides power supply for load.But because telecommunication system requires six synchronised generators, having under the situation of civil power, driving generating, under the situation of no civil power, generating electricity by internal combustion engine drive by synchronous motor.This just makes that generator unit structure is complicated, makes the reliability decrease of generating set, and cost increases.
Summary of the invention
The object of the present invention is to provide the electronic harmonic excitation six synchronised generators of a kind of single pivot, this generator not only can be generated electricity by internal combustion engine drive, and can also import the three-phase mains is power, makes the generator rotation, thereby send six cross streams electricity, to satisfy the needs of UPS load.
Technical scheme of the present invention is: arrange three cover windings in the electronic harmonic excitation six synchronised generators of a kind of single pivot, motor stator, first cover is the three-phase synchronous motor winding, and second cover is six synchronised generator windings, and the 3rd cover is humorous wave winding.Rotor adopts the non-salient pole structure, and the punching of rotor is the whole punching of non-salient pole, and the punching of rotor is made up of canine tooth and little tooth.When the three-phase mains charges into winding, form a rotating magnetic field, humorous wave winding is that rotor is supplied with exciting current, and rotor and motor stator rotating magnetic field are rotated synchronously, thereby makes the second cover winding send six cross streams.
The invention has the advantages that: generator adopts the single pivot stator structure, without the driving of other devices, under the situation that inserts the three-phase mains, six cross streams that output UPS even load needs, simplify the manufacturing process of generating set, reduced manufacturing cost, improved the reliability of generating set.
