Abstract
The invention provides a variable-speed constant-voltage generator. The generator adopts fundamental wave and harmonic wave excitation. Firstly, stator and rotor cores are lengthened so that the generator can reach the rated power at relatively low rotating speed; through using the fundamental wave and harmonic wave excitation, when the rotating speed range of the generator is changed, the technical performance of the generator can be ensured at the changed rotating speed; a shaft is of alloy steel, the comprehensive mechanical property of the shaft is enhanced, when the rotating speed of the generator is changed, the motor shaft still can bear the rated load. The generator uses the excitation system which is good in performance and is composed of fundamental wave and harmonic wave coils and AVR; when designing the electromagnetism, main sizes and parameters are selected and determined rationally, and both technical performance and economic performance are taken into consideration when the rotating speed of the generator is changed.
Description
Technical field
When the present invention relates to rotating speed (1350 ~ 1710r/min) range, reach the generator of rated power when exporting constant voltage, the slow-speed of revolution, be specifically related to a kind of variable-speed constant-voltage generator.
Background technology
Under normal circumstances, when generator is lower than rated speed, generator carrying load ability can decline, and voltage is also by instability.Make user when the diesel speed used changes, the electric elements cisco unity malfunction of load.And main diesel engine surplus power drive electrical generators can be utilized to generate electricity for boats and ships, just can improve the operational efficiency of main diesel engine, and power consumption and the expense of auxiliary power system can be saved.
Summary of the invention
The object of the present invention is to provide a kind of variable-speed constant-voltage generator, generator has when rotating speed (1350 ~ 1710r/min) range, reaches the feature of rated power when exporting constant voltage, the slow-speed of revolution.And when can ensure that generator speed changes, meet the requirement of generator indices.
The present invention is achieved like this, a kind of variable-speed constant-voltage generator, and it comprises front end housing, protective cover, fan, stator, rotor, rear end cap, outlet box; It is characterized in that: rotor is arranged on stator by the dead eye of rear end cap, front end housing, shaft coupling sheet are fixed on rotor by key, and protective cover is fixed on front end housing, are finally arranged on stator by outlet box; Distributing by harmonic winding part and first-harmonic windings section in first-harmonic and harmonic winding part is embedded in stator coring groove with stator main winding, and by exciter stator winding, unshakable in one's determination and stator core is arranged on support; Rotor windings rolls off the production line in rotor core, and fore bearing, fan, rotor core, exciter rotor iron core, rear bearing are arranged in rotating shaft; Harmonic winding part is connected by the pattern of connecting with first-harmonic windings section.When generator uses harmonic winding excitation, dynamo nonlinear load capacity can adapt to by force turn, but the more difficult control of excitation; And when generator uses first-harmonic winding excitation, excitation con-trol is comparatively easy, but dynamo nonlinear load capacity is poor.Not only first-harmonic adds harmonic excitation allows generator have excitation con-trol comparatively simple but also have the feature of stronger non-linear load capacity.Make generator when rotation speed change, still have good electric property.
Rotating shaft of the present invention adopts steel alloy to increase the comprehensive mechanical property of axle, and when making generator have rotating speed (1350 ~ 1710r/min) range, motor shaft still can bear nominal load.
First stator and rotor cores adopts and adds long process, makes generator when the comparatively slow-speed of revolution (1350r/min), can reach the object of rated power; Adopt first-harmonic to add harmonic excitation when making generator have rotating speed (1350 ~ 1710r/min) range, the technical performance of generator can be ensured in rotation speed change.
Advantage of the present invention is: during in order to ensure that generator has rotating speed (1350 ~ 1710r/min) range, reaches the object of rated power when exporting constant voltage, the slow-speed of revolution, adds stator and rotor cores and excitation system design.The excitation system of good performance adopting first-harmonic to add harmonic coil and AVR form, technical performance when guarantee generator speed changes.The excitation system of good performance that this generator adopts first-harmonic to add harmonic coil and AVR to form, and when Electromagnetic Design, Rational choice and determine key dimension, major parameter, can ensure technical performance when generator speed changes, can take economic performance into account again.
