Abstract
The utility model aims to provide a pole coil fixing structure of a generator rotor. The structure is suitable for a high-speed (two poles) generator, and especially for the generator capable of effectively preventing the pole coil of the generator rotor from deformation and coil throwing during the rotation at high speed under special conditions such as high temperature and long-time rotation. The pole coil fixing structure of the generator rotor consists of a rotor iron core (1) with a T-shaped groove, a pressing piece (2), a coil pressing plate, a bolt (3) and a nut (4), wherein two groups of pole coils are pressed by one pressing piece (2); and the pressing piece (2) is fixed on the T-shaped groove of the rotor iron core (1) through the bolt (3) and the nut (4).
Description
Technical field
The utility model relates to a kind of generator rotor field coil fixed structure.
Background technology
Traditional generator rotor field coil fixed structure is under adverse circumstances, when high speed rotating or sudden unloading process load, pole coil is easier to undergo mutation from groove even throw away, thereby cause generator coil to damage, the fault such as burn, have a strong impact on useful life and the safety and reliability of product.
Summary of the invention
The purpose of this utility model is to provide a kind of generator rotor field coil fixed structure, this structure is applicable at a high speed (2 utmost point) generator, particularly at high temperature, under the specific conditions such as long time running, can prevent effectively that generator rotor field coil from deforming and fishing line in high speed rotating.
A kind of generator rotor field coil fixed structure, formed by rotor core (1), briquetting (2), coil pressure plate, bolt (3) and nut (4) with T-shaped groove, it is characterized in that pushing down two groups of pole coils with a briquetting (2), briquetting (2) is fixed on the T-shaped groove of rotor core (1) by bolt (3), nut (4).
During the generator High Rotation Speed, because pole coil all pushed down by briquetting (2) and coil pressure plate on whole length direction fully, the distortion of pole coil when having avoided because of High Rotation Speed or hot state, loosening and throw away.Simultaneously axial T-shaped groove is convenient fixedly briquetting not only, but also is conducive to the ventilation and heat of rotor, reduces the temperature rise of generator.
The utility model is not only constructed rationally, and compact conformation is fixing simple and convenient, and good heat dissipation effect, can improve reliability and fail safe that generator uses.
Description of drawings
Fig. 1 is utility model generator rotor field coil fixed structure front view, and Fig. 2 is utility model generator rotor field coil fixed structure left view, and Fig. 3 is utility model rotor lamination of generator shape figure.
Embodiment
1. bolt (3) head is through in the T-shaped groove of rotor that coiling finishes.
