Abstract
The utility model discloses a novel wind-driven generator rotor neutral point connecting structure, which comprises a generator rotor spindle (1), a generator rotor (3) and a star-shaped joint ring (2), wherein the generator rotor (3) is fixedly connected to the generator rotor spindle (1); the star-shaped joint ring (2) is sleeved on the generator rotor spindle (1) and comprises a bus ring (4) and at least three buses (5); one ends of the buses (5) are welded on the bus ring (4), and the other ends of the buses (5) are welded at the end of a rotor coil (6); the buses (5) are uniformly distributed on the bus ring (4); and the rotor coil (6) is wound on the outer surface of the generator rotor (3). The novel wind-driven generator rotor neutral point connecting structure has the advantages of simple structure and firm connection, and the reliability of normal operation of the generator is greatly improved.
Description
Technical field
The utility model relates to a kind of generator amature parts, particularly a kind of novel wind generator rotor neutral point draw bail.
Background technology
Traditional wind-driven generator adopts mostly contiguous block directly is welded on the rotor neutral point connecting mode on the rotor coil.This connecting mode is simple in structure; But in the wind-driven generator running, rotor is in the state of running up, and the solder joint between contiguous block and the rotor coil is easy under action of centrifugal force, rupture; Thereby cause neutral point-connected damage, exist certain potential safety hazard.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, connect firm novel wind generator rotor neutral point draw bail.
The purpose of the utility model realizes through following technical scheme: a kind of novel wind generator rotor neutral point draw bail; It comprises generator amature main shaft, generator amature and stellate node ring; Generator amature is fixedly connected on the generator amature main shaft, and the stellate node ring set is contained on the generator amature main shaft.The stellate node ring comprises bus annulus and at least three buses, and an end of bus is welded on the bus annulus, and the other end of bus is welded on the end of rotor coil, and bus evenly distributes on the bus annulus.The generator amature outer surface is tied with rotor coil.
The utlity model has following advantage: the utility model is simple in structure, connects firmly, has improved the normal reliability of operation of generator to a great extent.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-generator amature main shaft, 2-stellate node ring, 3-generator amature, 4-bus annulus, 5-bus, 6-rotor coil.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1; A kind of novel wind generator rotor neutral point draw bail; It comprises generator amature main shaft 1, generator amature 3 and stellate node ring 2, and generator amature 3 is fixedly connected on the generator amature main shaft 1, and stellate node ring 2 is sleeved on the generator amature main shaft 1.Described stellate node ring 2 comprises bus annulus 4 and three buses 5, and an end of bus 5 is welded on the bus annulus 4, and the other end of bus 5 is welded on the end of rotor coil 6, and the angle between per two buses 5 is 120 °.Generator amature 3 outer surfaces are tied with rotor coil 6.
The course of work of the utility model is following: during assembling, stellate node ring 2 is sleeved on the generator amature main shaft 1, three buses 5 are welded on the end of rotor coil 6.In the generator operation process, stellate node ring 2 is sleeved on the generator amature main shaft 1, and the angle between per two buses 5 is 120 °, and such structure has farthest reduced the damage of centrifugal force butt welding point, has improved the reliability of generator operation.
