Abstract
The invention discloses an unloading device for a vertical-axis wind turbine. The unloading device comprises a disk generator, wherein the disk generator is arranged on a wind turbine. According to the unloading device for the vertical-axis wind turbine, high torque generated by the high-current wind turbine is applied to a blade shaft to fulfill the aim of strong wind deceleration of the wind turbine, and an unloading resistor cabinet is replaced; due to the adoption of a disk structure, the device is small in floor area, convenient to mount, low in machining cost and stable in performance; the addition of a load to the wind turbine is not required, so that influence on the performance and service life of the wind turbine is avoided; redundant energy generated by wind energy can be converted into electric energy for utilization, so that the device is diversified, and the utilization rate of the wind energy is increased.
Description
Technical field
The present invention relates to a kind of relief arrangement of wind-driven generator, especially the relief arrangement of vertical wind power generator.
Background technique
Along with popularizing of new energy, wind-driven generator is no longer new term, is accepted by numerous crowds, and the production technology of wind-driven generator was also maked rapid progress and developed fast at these several years.The generating efficiency of wind-driven generator and the utilization ratio of wind energy have become the key index that wind-powered electricity generation industry reduces product cost, enhances product performance.
The general work wind speed range of wind-driven generator is between 3-30m/s wind speed, and 30m/s is braking state.3-15m/s is the startup rated wind speed of blower fan, and in this wind speed range, blower fan carries out normal power generation work; 13-30m/s is the speed limit work wind speed of blower fan, and in this wind speed range, blower fan is operated under off-load low speed state.The off-load reduction of speed mode that producer conventionally adopts is: export one group of control signal by control unit detecting after wind speed is greater than rated wind speed, start electric power generation unloading resistance and motor winding parallel, reach the object of reduction of speed by the output loading of the generator that breezes up.
The mode of off-load reduction of speed has a lot of drawbacks, as:
(1) off-load reduction of speed plays the object of reduction of speed, but the output loading meeting of the generator that breezes up increases winding current, and much larger than specified generation current, generator temperature rise is very fast, and the life-span of generator can be greatly affected.
(2), under the mode of off-load reduction of speed, wind-driven generator sends the electric weight that exceedes rated power and can be diverted on electric power generation unloading resistance, lays down by the mode that electric energy is converted to heat energy, causes the wasting of resources.
(3) electric power generation unloading resistance is by much forming an off-load cabinet, and volume is directly proportional to the power of generator, is generally operational in indoor or has under the environment of anti-thunderstorm measure, and the existence of off-load cabinet has increased dutycycle undoubtedly.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of brand-new vertical axis aerogenerator relief arrangement.For solving the problems of the technologies described above, vertical axis aerogenerator relief arrangement of the present invention, comprises disk generator, and described disk generator is arranged on the upper of wind-driven generator.
Preferably: in described disk generator, be provided with motor winding, on motor winding, sleeve rotor is installed, on the hub of sleeve rotor, inlay magnet steel, magnet steel towards motor winding apart from 2mm, in sleeve rotor, be set with wind driven generator principal shaft, sleeve rotor and wind driven generator principal shaft pass disk generator casing, blade wheel hub is installed on wind driven generator principal shaft top, magnetic coil base is installed in blade wheel hub lower end surface, on magnetic coil base, magnetic coil is installed, the below of magnetic coil is provided with the card wheel that slides, magnetic coil is coated on the card wheel upper end of sliding, the card that slides is taken turns the tooth pitch of lower end from the sleeve rotor teeth groove 5mm of sleeve rotor upper end.
Vertical axis aerogenerator relief arrangement of the present invention, the high moment of torsion that utilizes large current generator to produce is added on sharf realizes the object of the strong wind reduction of speed to wind-driven generator, replaces electric power generation unloading resistance cabinet.The utility model adopts tray type structure, and duty area is little, convenient to be installed, and processing cost is low, stable performance.The present invention, without increase load on wind-driven generator, does not affect performance and the life-span of wind-driven generator, and the unnecessary Conversion of Energy simultaneously again wind energy being produced is that electric weight is used, and has realized a machine diversification, has improved wind energy utilization.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
In order further to understand structure of the present invention, feature and other object, be now described in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment is only for technological scheme of the present invention is described, and non-limiting the present invention.
Embodiment:
As shown in Figure 1: vertical axis aerogenerator relief arrangement of the present invention, comprise disk generator 2, described disk generator 2 is arranged on the upper of wind-driven generator 1, motor winding 3 is installed in disk generator 2, sleeve rotor 8 is installed on motor winding 3, on the hub of sleeve rotor 8, inlay magnet steel 7, magnet steel 7 towards motor winding 3 apart from 2mm, in sleeve rotor 8, be set with wind driven generator principal shaft 10, sleeve rotor 8 and wind driven generator principal shaft 10 pass disk generator casing 2, blade wheel hub 11 is installed on wind driven generator principal shaft 10 tops, in blade wheel hub 11 lower end surfaces, magnetic coil base 6 is installed, magnetic coil base 6 is provided with magnetic coil 5, the below of magnetic coil 5 is provided with the card wheel 4 that slides, magnetic coil 5 is coated on card wheel 4 upper ends of sliding, the card that slides is taken turns the tooth pitch of 4 lower ends from the sleeve rotor teeth groove 95mm of sleeve rotor 8 upper ends.
Working principle: in the time that wind speed is greater than specified (13-30m/s), export one group of signal by control unit and be given to magnetic coil 5, magnetic coil 5 is worked, control card wheel 4 actions of sliding, the tooth of slip card wheel 4 upper ends is stuck in the sleeve rotor teeth groove 9 of disk generator sleeve rotor upper end, drags disk generator 2 and rotate, disk generator 2 is exported threephase AC to controller unit,, convert direct current to and be input to storage battery or combining inverter three phase current electric rectification by controller.
The torsional interaction of disk generator output is on the rotor shaft of wind-driven generator, wind speed is larger, disk generator rotating speed is faster, the moment of torsion of output is larger, the rotor shaft of wind-driven generator is subject to the impact of disk generator resistance moment of torsion, rotating speed reduces, when rotating speed is reduced to rated speed, the signal of control unit output turn-offs, magnetic coil 5 quits work, and the card wheel 4 that slides departs from the sleeve rotor teeth groove 9 of sleeve rotor upper end, and disk generator drags power and quits work owing to losing, resistance moment of torsion on wind turbines rotor axle disappears, and wind-driven generator is normally worked.
