Abstract
This invention discloses a new air-gap generator, a single phase or three-phase brushless synchronized generator, in which, the rotor is a convex structure, the excitation is triple-frequency harmonic the generator has no AVR and keeps voltage stable, the electric performance is basically the same with that of the generator with AVR. The triple harmonic induced potential change along with the changes of the load. When the load increases, the triple-frequency harmonic induced potential will change and the excitation increases to keep a stable voltage, having the ability of starting an induction motor.
Description
Technical field
The present invention relates to a kind of power-supply device, especially a kind of new gap structure generator.
Background technology
Generally middle-size and small-size single-phase or three-phase brushless synchronous generator all is to have automatic voltage regulator AVR, to keep generator voltage stable in running, but the failure rate of AVR itself is higher, the fault of at present general generator is mostly caused by AVR, this is for power supply reliability being required extra high occasion, generally require generator not to be with AVR, for example: refrigerating box generator special etc.But the output voltage with automatic voltage regulator AVR generator is not difficult to stablize, at present both at home and abroad not with the generator steady state voltage regulation of AVR more than 6%, can not satisfy user's requirement.
Summary of the invention
The object of the present invention is to provide a kind of new gap structure generator, this new gap structure generator is exactly to want generator under the situation with AVR not, realize generator stablizing, and still keep stable for different capacity factor load generator output voltage from zero load to nominal load voltage.
Technical scheme of the present invention is: a kind of new gap structure generator, generator is middle-size and small-size single-phase or three-phase brushless synchronous generator, arrange the third harmonic excitation winding in the main frame stator, it is characterized in that: the generator amature punching of this new gap structure generator is the whole punching of salient pole, periphery, pole shoe middle part is an arc section, and be even air gap between the stator, periphery, pole shoe two ends is a straightway, and is non-homogeneous air gap between the stator; Rotating pole-piece even air gap section is arranged the absolute damping copper bar.
The invention has the advantages that: generator is not with automatic voltage regulator AVR, can reach the stable of in running voltage, simplify the manufacturing process of generator, reduce manufacturing cost, particularly improve the reliability of generator greatly, had tangible economic benefit and social benefit.Above-mentioned technology is applied to the medium and small generator field, the reliability of generator under various harsh natural conditions is greatly improved, make this kind generator be particularly suitable for being applied to refrigerator car, military affairs, fishing boat, locomotive etc. the extra high occasion of portable power source reliability requirement.

Embodiment
A kind of new gap structure generator, generator is middle-size and small-size single-phase or three-phase brushless synchronous generator, arrange the third harmonic excitation winding in the main frame stator, the generator amature punching 1 of this new gap structure generator is the whole punching of salient pole, pole shoe 2 middle parts peripheral 3 are arc section, and be even air gap between the stator 5, pole shoe 2 two ends peripheral 4 are straightway, and are non-homogeneous air gap between the stator 5; Rotating pole-piece 2 even air gap sections are arranged absolute damping copper bar 6.Generator is middle-size and small-size single-phase or three-phase brushless synchronous generator, arrange the third harmonic excitation winding in the main frame stator, because first-harmonic winding and triple-frequency harmonics winding be for the difference of first described air gap armature reaction, the strong load tracking ability of third harmonic excitation makes stablizing that generator can sustaining voltage under zero load and different loads situation.
Example is a RF-15-CIMC-SB refrigerating box generator special, be three-phase brushless synchronous generator, be not with AVR, the whole salient pole punching of rotor core quaternary structure, frequency 60Hz, rated power 15kw, rated voltage 460V or 230V, rated power factor are 0.8, and number of stator slots is 36 grooves, stator core is embedded with stator main winding and triple-frequency harmonics winding, and the rotor winding is centralized winding.
As its electrical principle such as figure two; A or A ' are main frame stator winding (also can be single-phase winding), and B is the triple-frequency harmonics winding, and C is an adjustable resistance; by its can adjust output voltage (this voltage can be adjusted within certain scope) of generator; D is a single-phase bridge rectification, and E is the exciter excitation winding, and F is an exciter armature winding; G is the rotation three-phase bridge rectification; H is a piezo-resistance, and three-phase bridge rectifier is protected, and L is the main frame excitation winding.This generator is not with AVR, but stable (the steady state voltage regulation is 2.5%) that can sustaining voltage, electricity function index is with the middle-size and small-size single-phase of band AVR or three-phase brushless synchronous generator is basic identical.
