Abstract
The utility model relates to a pole-changing speed control duplex-winding coil structure which comprises insulating materials of a winding coil with high number of poles, a winding coil with low number of poles, and a wrapping winding coil. Each stator slot internally includes two stator coils which are independent in functions and integrated in appearance, both of two sets of windings adopt Y connection and separate wiring, and a stator outgoing line is directly linked with a power grid through a power switching system. In the utility model, the characteristic of instability of air quantity in the process of wind power generation is fully considered, and the function of direct on-grid power generation of a wind generator without a frequency converter is realized. In the pole-changing speed control duplex-winding coil, each set of winding is separately led out, and switched to the corresponding winding by the power switching system according to rotation speed changes of a motor, so as to generate electricity with different power to the power grid.
Description
Technical field
The utility model relates to the motor windings structure, relates in particular to a kind of not by frequency converter and directly winding construction of the pole changing aerogenerator stator of linked network.
Background technology
Wind power generation has become industry with fastest developing speed in the green energy resource.Wind-driven generator generally need generate electricity by frequency converter, and cost is very high.If can not adopt frequency converter, and, then will save great amount of cost for the user with the direct linked network generating of wind-driven generator.
The utility model content
The purpose of this utility model is to provide a kind of pole changing double winding loop construction, realizes that wind-driven generator runs on two kinds of power ratings, improves the efficient of generator, by the direct linked network generating of frequency converter, does not reduce cost.
The technical solution of the utility model is as follows:
A kind of pole changing double winding loop construction, comprise the high number of poles winding coil and the low number of poles winding coil that are arranged in the same stator slot, wrap up separately respectively described high number of poles winding coil and low number of poles winding coil outside insulating material, described wrapping has the high number of poles winding coil of insulating material and wrapping to have the low number of poles winding coil of insulating material to turn to a coil integral body, and described coil integral outer wrapping has insulating material.
Its further technical scheme is: described high number of poles winding coil and the fusiformis coiling together of low number of poles winding coil, and independently draw separately at the coil two ends.
Useful technique effect of the present utility model is:
The utility model takes into full account this characteristic of unsteadiness of wind power plant air quantity, substantially do not increasing under the condition of cost, the aerogenerator stator coil design is become two absolute coils of every groove, two coils carry out the fusiformis coiling together, realize the two ends outlet according to actual conditions adjustment lead-in wire position again, realize the independence on the function and realize one in appearance.Utilize pole changing, realized that wind-driven generator runs on two kinds of power ratings, make full use of wind resource, improve the efficient of generator, or not do not reduce cost by the direct linked network generating of frequency converter.When wind field air quantity hour motor speed is low, the mains switch switched system switches on high number of poles winding with generator, and generator sends low-power to electrical network; Motor speed uprises when the wind field air quantity is big, and the mains switch switched system switches on low number of poles winding with generator, and generator sends high power to electrical network.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is the coil overall schematic of fusiformis coiling.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Shown in Fig. 1～3, the utility model comprises high number of poles winding coil 1 and the low number of poles winding coil 2 that is arranged in the same stator slot, wrap up separately respectively high number of poles winding coil 1 and low number of poles winding coil 2 outsides insulating material 3, wrapping has the high number of poles winding coil 1 of insulating material 3 and wrapping to have the low number of poles winding coil 2 of insulating material 3 to turn to a coil integral body 4, wraps up one deck insulating material 3 again in whole 4 outsides of coil then.High number of poles winding coil 1 and low number of poles winding coil 2 carry out the fusiformis coiling together, realize the independence on the function and realize one in appearance, and independently draw separately at the coil two ends.Two cover windings all adopt Y to connect, wiring separately, stator lead-out wire by the mains switch switched system directly and electrical network link, send different capacity thereby change and switch to corresponding winding to electrical network by the mains switch switched system according to the big or small motor speed of wind field air quantity.
The above only is a preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
