Description
Technical field
The utility model relates to a kind of wind-driven generator, a kind of split type permanent magnet synchronous wind generator of more specifically saying so.
Background technology
Present high-power grid type wind-driven generator mainly is to adopt synchronous generator, asynchronous generator, double speed asynchronous generator or double-fed asynchronous generator, and the whole generating machine is an integral body, and external shape is streamlined.
When adopting synchronous generator, require the rotating speed of wind energy conversion system very stable, for this reason, must adopt baroque speed regulator to keep the invariablenes turning speed of wind energy conversion system automatically, this just makes the whole wind power generation device become very complicated.
Adopt synchronous generator or various asynchronous generator no matter be, its common drawback is: 1, will drive raising speed mechanism by blade, drive generator for electricity generation by raising speed mechanism, and raising speed mechanism is bulky, and the phenomenons such as leakage of oil, damage tooth, damage casing that occur through regular meeting in service are in case above-mentioned phenomenon occurs, evaporating, emitting, dripping or leaking of liquid or gas gently then takes place, contaminated environment, heavy then shutdown maintenance can not be generated electricity; 2, generating efficiency is very low when hanging down wind speed, can not make full use of wind energy again when high wind speed; Noise is big when 3, moving.
Along with continuous advancement in technology, the single-machine capacity of high-power grid type wind-driven generator is increasing, its volume is then increasing, weight is more and more heavier, again because the whole generating machine is an integral body, must use superhuge means of transportation and hoisting equipment just to transport and install, both increase cost, and brought many inconvenience for again transportation and installation.
Fusiform external shape is because its turbulent flow and wake flow are less, therefore when wind-force affacts on the fan blade, active force to the whole wind power generator almost is unidirectional, when running into the strong wind sky, the folk prescription that is born on the pylon can be very big to active force, poor stability.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, be convenient to transport and the split type permanent magnet synchronous wind generator of installation, grid type.
In order to realize above-mentioned purpose, the split type permanent magnet synchronous wind generator that is provided, comprise pylon, the upper end of pylon is connected to revolving body by bearing, revolving body is fixed in the inner chamber in cabin, on revolving body, be connected with stator support and central shaft, be connected to rotating disk by bearing on the central shaft, be connected with rotor case on the rotating disk, the blade end of rotor case is streamlined, be connected with blade by wheel hub on the rotating disk, on the periphery of stator support, be inlaid with equally distributed stator core, be wound with the three-phase coil winding on the stator core, be inlaid with equally distributed permanent-magnet at rotor case corresponding to the anchor ring inboard at stator core and three-phase coil winding position, leave air gap between permanent-magnet and the stator core, its design feature is that stator support and rotor case all are respectively splits, the quantity of its split is two bodies at least, is assembled into one with bolt and cylindrical pin with internal thread between the split.
The split quantity of above-mentioned stator support and rotor case can be identical, also can be inequality.
The back segment in above-mentioned cabin is the hemisphere hull shape.
Split type permanent magnet synchronous wind generator provided by the utility model, be directly to drive rotor case by blade to rotate, the permanent-magnet that is embedded on the rotor case medial surface rotates thereupon synchronously, three-phase coil winding cutting magnetic line in the stator, produce induced electromotive force, pass through high efficiency " friendship orthogonal " current transformer of outfit again, the rotating speed that makes the rotor that is driven by blade can change in big scope with the size of wind speed, energy Maximum Power Output when high wind speed, when hanging down wind speed, can improve generating efficiency, effectively raise utilization ratio of wind energy, annual energy output improves 25%-40% than the wind turbine generator of other type of same capability.Owing to saved the raising speed mechanism bulky, that structure is numerous and diverse, make the wind turbine generator reduction 20%-25% of the volume and weight of whole wind turbine generator on the one hand than other type of same capability, and reduced noise, the minimizing of parts must reduce the probability that breaks down on the other hand, has improved the generating set reliability of operation.Stator support and rotor case adopt and divide body structure, use general means of transportation and hoisting equipment just to transport and install, and have both reduced transportation and mounting cost, have made things convenient for transportation, have reduced installation difficulty again.The cabin back segment is designed to be the hemisphere hull shape, when making distinguished and admirable arrival cabin back segment, can produce big turbulent flow and wake flow, the whole wind power generator is produced a reciprocal active force, so the power that affacts on the pylon is just very little, effectively increase stability of tower, strengthened wind loading rating.
