Abstract
The utility model relates to a generator, particularly to a double feed asynchronous wind mill generator, comprising a shaft supported on a bear of the generator, a rotor punching sheet fixed on the shaft, a rotor coil tabled on the rotor punching sheet is of a scattered winding structure, a terminal of the rotor coil is connected with a jug line of the rotor through a terminal fixing annular plate fixed with the shaft, the jug line of the rotor passes through a shaft hole of the shaft and led to a terminal box of the rotor after connecting with a collector ring. Compared with the prior art, the utility model has the advantages that, a notch opened on the rotor punching sheet is a semi-closed entry groove, namely an open of the groove is small, causing a waveform of the generating voltage is good; the rotor coil wound on the rotor punching sheet is the special corona resistant enamelling circle copper wire, thereby reducing material cost, but also ensuring operation reliability; the rotor coil adopt the scattered winding structure, which markedly reduces welding points, thereby greatly reducing sealedoff risk of the welding points in operation, furthermore increasing operation reliability.
Description
Technical field
The utility model relates to a kind of generator, particularly a kind of dual-feed asynchronous wind power generator.
Background technology
Existing dual-feed asynchronous wind power generator structure is that (referring to Fig. 1) has a generator housing 3, be fixed with stator punching 4 in generator housing 3 inboards, be wound with stator coil 1 on stator punching 4, the terminals of stator coil 1 join with the stator terminal box 2 that is fixed on the generator housing 3.In generator housing 3, rotating shaft 5 is arranged with bearings, in rotating shaft 5, be fixed with rotor punching 6, be wound with rotor coil on rotor punching 6, rotor coil is hard winding, and the terminals of rotor coil penetrate in the axis hole in the rotating shaft 5 and with the rotor junction box 17 that is fixed on the generator housing 3 and join.Because the rotor winding is hard winding, its rotor punching 6 adopts open slot mostly, and open slot is relatively poor to the generator voltage waveform, and is influential to power generating quality; Hard winding uses copper bar and insulating material cost height, and cost performance is low; Pad is many, and the welding procedure complexity is prone to the rosin joint phenomenon, when high-speed cruising, is easy to break down.
Summary of the invention
The purpose of this utility model provides a kind of good voltage waveform, low, the easy processing of cost, is difficult for taking place the dual-feed asynchronous wind power generator of interruption of service, overcomes the deficiencies in the prior art.
Dual-feed asynchronous wind power generator of the present utility model, it comprises the rotating shaft that is supported on the dynamo bearing, is fixed on the rotor punching in the rotating shaft, it is characterized in that: the rotor coil that embeds on rotor punching is the winding construction that looses, the terminals of rotor coil by the wiring of fixedlying connected with rotating shaft fixedly ring flat-plate and the big line of rotor join, the big line of rotor pass in the rotating shaft axis hole with guide in the rotor junction box after collector ring links to each other.
Dual-feed asynchronous wind power generator of the present utility model, be fixed with balancing frame in the wherein said rotating shaft, the cylindrical of balancing frame by spacer shell and wiring fixedly the endoporus of ring flat-plate fixedly connected, balancing frame and wiring fixedly ring flat-plate are staggered in the axial direction mutually, make the big line of balancing frame and rotor lay respectively at the fixedly both sides of ring flat-plate of wiring in the axial direction.
The utility model compared with prior art has following advantage: opening the notch that dashes on rotor punching is semi-enclosed slot, and promptly the opening of groove is little, makes the generating voltage waveform good; The rotor coil that embeds on the rotor punching is the special enamel insulated round copper wire of anti-the corona, has both reduced material cost, has guaranteed reliability of operation again; Rotor coil adopts the winding construction that looses also obviously to reduce solder joint, thereby has greatly reduced the risk that solder joint snaps when moving, and has further improved the motor reliability of operation.
