Abstract
This invention discloses a proper fractional slot sine winding of an equal-distance synchronous generator. When each phase slot number of each pole q<1, the winding can continuously wind down to form double winding by laying out the winding with different turn ratios and same pitch coils, its technology is simpler than that of unequal turn concentric sine winding and makes its phase voltage wave be of high-degree sine and its phase voltage wave high-degree sine and its harmonic wave is lower than the sine windings of unequal turn concentric double layer low harmonic magnetic potential, easy to be made into precision high-level medium frequency AC power source, meeting the need of devices with high electric performance.
Description
Technical field
The present invention relates to a kind of power-supply device, especially a kind of equidistant synchronous generator proper faction groove sinusoidal winding.
Background technology
General multipole synchronous generator factor receptor is long-pending to be limit, and every extremely every phase groove is counted q and usually got mark.And in intermediate frequency generator often q also may get proper fraction less than 1.Proper faction groove by general AC Windings principle be double-deck short distance formula structure or the double-deck low phase belt the harmonics of magnetic force winding that does not wait the circle concentric type all can't accomplish to make its line voltage and phase voltage irregularity of wave form all less than 2% level.
Summary of the invention
The object of the present invention is to provide a kind of equidistant synchronous generator proper faction groove sinusoidal winding, the structure of this winding can overcome above-mentioned defective, and can make the irregularity of wave form of line voltage and phase voltage equal＜1%, reach leading domestic level.
Technical scheme of the present invention is: a kind of equidistant synchronous generator proper faction groove sinusoidal winding, the every extremely every phase groove of this winding is counted q＜1, this winding turns is than winding symmetric arrangement different, the identical coil of pitch, winding can even form two repeatedly formula windings down around connecting, and constitutes three phase windings by two repeatedly windings of 2: 3 of two kinds of turn ratioes.Two repeatedly windings are for by equidistantly being made up of two kinds of the different numbers of turn or multiple coil.Connecting under company at non junction, is three-phase symmetric winding.
The invention has the advantages that: 1) realized fractional-slot q＜1 simple in structure, technology is traditional and can constitute the purpose of positive chorded winding.And its voltage harmonic content is lower than the double-deck positive chorded winding that does not wait circle concentric type structure; 2) though three phase windings by equidistant and does not wait circle to constitute, but still have realized that jointless company is around connecting non junction winding down., be better than the defective that the three-decker winding is difficult to make non junction and connects winding under even.Consistent with general two technologies that change, economical rationality.3) because q＜1, realized that simple in structure, technology makes things convenient for, little, the lightweight purpose of volume, because sinusoidal the layout, realized that again generator line voltage and phase voltage waveform are all highly sinusoidal, the electric property excellence, can make the precision voltage source of high-precision naval vessels, ground, airport intermediate frequency power supply and precision instrumentation checkout equipment etc. as core technology, electric property is on the leading domestic level, and also reaches world-class levels.
