Abstract
Wire connection structure in a kind of rotor of wind-driven generator, belongs to wind-driven generator group part field.The quantity of central tap is three, and it is connected between two adjacent central taps by middle line connecting line, three middle line connecting lines constitute a circular ring structure, it is reasonable in design, middle line connecting line is using low-angle bending structure after annealing, the damage inside middle line connecting line is reduced, central tap and middle line connecting line use plane-plane contact, increase contact area.The service life of wind-driven generator is improved, and then is improved work efficiency.
Description
Technical field
The utility model belongs to wind-driven generator group part field, and in particular to a kind of rotor middle line of wind-driven generator
Connection structure.
Background technique
In the case where the overall situation of green energy resource is greatly developed in the whole world, wind energy is as a kind of clean renewable energy, increasingly
Attention by countries in the world.Since 2008, the upsurge of domestic wind-powered electricity generation construction has also arrived perfervid degree.Wind-driven generator
Effect be by wind wheel transmitting come mechanical energy be converted into electric energy, be core component indispensable in wind generator system.
Wind-driven generator puts into operation so far, has stepped into the maintenance stage.To a large amount of failure wind-driven generators
During maintenance, most failure wind-driven generators are found（The hard winding of rotor）Fortune can not be put into because of rotor midline
Row.Traditional rotor centerline construction is central tap and middle ring by being welded to connect one, due to central tap be cold bending and
Bending angle is excessive, and inside is caused to be damaged, and generates galvanic corrosion in injury region after current transformer power supply, causes to be broken, influence to make
With.
Summary of the invention
The utility model aim provides wire connection structure in a kind of rotor of wind-driven generator, solves the prior art not
Foot reduces the failure rate of rotor middle line, promotes the stable operation cycle of wind-driven generator.
The utility model is achieved in the following ways wire connection structure in a kind of rotor of wind-driven generator, and middle line connects
The quantity of head is three, and is connected between two adjacent central taps by middle line connecting line, and three middle line connecting lines are constituted
One circular ring structure.Two ends of the middle line connecting line form attachment base by annealing bending, between two attachment bases
Namely the intermediate position of middle line connecting line is segmental arc.
Two through-holes are respectively equipped on the central tap and attachment base, bolt passes through through-hole and nut for central tap
It is fixedly connected with attachment base.
The material of preferred central tap and middle line connecting line is all made of copper bar.
The radian of preferred segmental arc is 120 °
The beneficial effects of the utility model are reasonable in design, and middle line connecting line uses low-angle bending structure after annealing,
The damage inside middle line connecting line is reduced, central tap and middle line connecting line use plane-plane contact, increase contact area.It improves
The service life of wind-driven generator, and then improve work efficiency.
Detailed description of the invention
Fig. 1 is overall structure diagram；
Fig. 2 is middle line connecting wire structure figure；
As described in Fig. 1 to Fig. 2, central tap（1）, attachment base（2）, segmental arc（3）, bolt（4）, nut（5）.
Specific embodiment
Wire connection structure in a kind of rotor of wind-driven generator, central tap（1）Quantity be three, and adjacent two
Central tap（1）Between connected by middle line connecting line, three middle line connecting lines constitute a circular ring structures.
Two ends of the middle line connecting line form attachment base by annealing bending（2）, strict guarantee bending angle,
In two attachment bases（2）Between namely middle line connecting line intermediate position be segmental arc（3）.
The central tap（1）And attachment base（2）On be respectively equipped with two through-holes, bolt（4）Pass through through-hole and nut
（5）By central tap（1）And attachment base（2）It is fixedly connected, and forms plane-plane contact, ensure that effective contact area.
Preferred central tap（1）High-quality copper bar is all made of with the material of middle line connecting line.
Preferred segmental arc（3）Radian be 120 °
The foregoing is merely the embodiments of the present invention, and the guarantor of non-limiting the utility model
Range is protected, any modification, equivalent substitution and improvement done within the spirit and principle of the utility model expand
Exhibition etc., is included in the protection scope of the present invention.
