Abstract
The utility model discloses a brushless single-phase synchronous generator of double-pole induction harmonic self-excitation which is characterized in that the rotor of the electric generator is of salient pole structure and provided with a main winding, a dc double-pole winding, and a triple harmonic winding. The utility model can be matched with a diesel engine, a gasoline engine, a wind power machine, or a water turbine to be an electric generator composition. The utility model can be used as a required or spare power source in countrysides, towns, theatres, sentry posts, hospitals, etc.
Description
The utility model belongs to generating equipment, is a kind of brushless single phase synchronous generator that adopts induced excitation.
At present, the domestic and international brushless single phase synchronous generator of producing mainly contains two kinds of patterns: a kind of is the no-brush synchronous generator that band is handed over the machine of encouraging; A kind of is electric capacity self-excitation type no-brush synchronous generator.The former friendship machine of encouraging has increased the unit axial length, does not encourage machine though the latter has to hand over, and the electric capacity winding need be set and add capacitor.Therefore, above-mentioned two kinds of generators all have the big and baroque shortcoming of volume.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of volume brushless single phase synchronous generator little, in light weight, simple in structure, easy to maintenance.
Technical conceive of the present utility model is: utilize with the alternative traditional friendship of pivot times utmost point direct current winding (2) machine of encouraging and realize induced excitation, shortened the axial length of unit greatly; Utilize triple-frequency harmonics winding (5) instead of capacitor to realize self-excitation, need not to add capacitor.
Description of drawings: accompanying drawing is a principle schematic of the present utility model.(1) is main winding among the figure, and (2) are a times utmost point direct current windings, and (3) are diodes, and (4) are variable resistors, and (5) are the triple-frequency harmonics windings, and (6) are excitation winding, and (7) are rotating diodes, and (8) are field spiders.
Architectural feature of the present utility model is that rotor (8) is salient-pole structure, only has a cover to pass through the voluntarily Exciting Windings for Transverse Differential Protection of short circuit (6) of diode (7) at field spider (8). Three cover windings are arranged: main winding (1), direct current times utmost point winding (2) and triple-frequency harmonics winding (5) on the stator. Main winding (1) and direct current times utmost point winding (2) be utmost point relation at double, and triple-frequency harmonics winding (5) is connected with a direct current times utmost point winding (2) by diode (3).
This utility model is utilized magnetic field induced potential in Exciting Windings for Transverse Differential Protection (6) of direct current times utmost point winding (2), and the electric current after rotating diode (7) rectification is set up the motor main field; Electric current in the direct current times utmost point winding (2) is supplied with after diode (3) rectification by triple-frequency harmonics winding (5). Resistance (4) between change triple-frequency harmonics winding (5) and direct current times utmost point winding (2) can carry out voltage and adjust. The converse field component of main winding (1) will Intensifying current in the Exciting Windings for Transverse Differential Protection (6) is realized constant voltage.
This utility model belongs to the single phase synchronous generator that is applicable to 15 kilovolt-amperes and following capacity, become generating set with diesel engine, gasoline engine, wind-powered machine or the hydraulic turbine are supporting, can be as the indispensability or the standby power supply apparatus of rural area, cities and towns, building site, movie theatre, sentry post, hospital etc.The voltage regulation of this utility model can remain on ± 5% in, can satisfy four class power station requirements.Hand over the brushless single phase synchronous generator of the machine of encouraging to compare with band, this machine can save a friendship and encourage machine, and the generator volume dwindles 25%, and cost reduces by 20%; Compare with the condenser type brushless drive, though set up the triple-frequency harmonics winding, the total copper consumption of motor slightly reduces.Simultaneously, removed capacitor, improved voltage waveform, electric efficiency has improved two percentage points.
Provide an embodiment below:
Make the generator of a rated power 5KVA, rated voltage 230V, rated current 21.74A, rated power factor 1.0, rated speed 1500rpm makees prime mover by diesel engine.
The main data of generator: main winding (1) 156 circle; Direct current times utmost point winding (2) 216 circles; Triple-frequency harmonics winding (5) 84 circles; Excitation winding (6) 380 circles; Diode (3) is 10A, 500V; Resistance (4) is the porcelain dish variable resistance, 0-15 Europe, 100 watts; Rotating diode (7) is 10A, 600V; Adopt T
2The S160 iron core.
Main performance index: voltage regulation 5%; Efficient 80.2%; Voltage waveform sinusoid aberration rate 10.2%.
Claims (3)
1, a kind of brushless single phase synchronous generator, this generator comprises rotor and stator, it is characterized by: rotor (8) is a salient-pole structure, three cover windings is arranged: main winding (1), direct current times utmost point winding (2) and triple-frequency harmonics winding (5) on the stator.
