Abstract
The utility model discloses a phase modulation stator winding end fixing structure comprises notch cushion, sloping block, ligature rope, pressure finger, gumming polyester felt, through add the boss cushion on the stator clamping ring as radial strong point, fills the clearance between boss cushion and the support ring through adjusting the cushion, effectively supports the support ring and then supports stator winding end, becomes a whole with stator winding and support ring ligature through tying up the rope, the utility model discloses simple reliable, with low costs, convenient to use can effectively improve stator winding end rigidity intensity and reinforcing and bear the ability of electromagnetic force under the accident.
Description
The technical field is as follows:
the utility model relates to a large-scale latent utmost point synchronous generator field especially relates to a phase modulation machine stator winding end rigid strength structure.
Background art:
the end part of the stator winding of the generator becomes an important link for safe and stable operation of the generator due to weak fixation, and along with the increase of the single-machine capacity of the generator, the electromagnetic force acting on the end part of the stator winding is increased, so that the problem of vibration caused by the increase of the capacity of the generator is increasingly emphasized.
The invention content is as follows:
the utility model aims at disclosing a can effectively improve stator winding end rigidity intensity and reinforcing and bear the phase modulation stator winding end fixed knot who falls electromagnetic force ability under the accident and construct, technical scheme is: the stator winding comprises a support ring, an adjusting cushion block, a binding rope, a stator pressing ring and a glue dipping polyester felt, wherein the support ring is an insulating ring with a trapezoidal section, the section of the support ring is provided with a groove, a boss cushion block made of a non-magnetic material is welded on the inner circle of the stator pressing ring, the adjusting cushion block is installed between the support ring and the boss cushion block and located at the groove, the glue dipping polyester felt is padded between the support ring and the stator winding, the stator winding and the support ring are bound and fixed through the binding rope, and the adjusting cushion block is an.
The technical effects are as follows:
the utility model discloses an add the boss cushion on the stator clamping ring and fill the clearance between boss cushion and the support ring as radial strong point through adjusting the cushion, effectively increase the support ring and then support stator winding tip, become a whole with stator winding and support ring ligature through tying up the rope, use the utility model discloses can effectively improve stator winding tip rigidity intensity and reinforcing and bear the ability of electromagnetic force under the accident afterwards.
Description of the drawings:
FIG. 1 is a view showing a structure for fixing the end of a stator winding
FIG. 2 is a side view of the fixing structure
FIG. 3 is a cross-sectional view of the adjusting pad
FIG. 4 is a view of the adjustment block A
The specific implementation mode is as follows:
the phase modifier stator winding end fixing structure shown in the figures 1, 2, 3 and 4 comprises a support ring 1, an adjusting cushion block 2, a binding rope 3, a stator pressing ring 4 and a glue dipping polyester felt 5, wherein the support ring 1 is an insulating ring with a trapezoidal section, a groove 6 is formed in the section of the support ring 1, a boss cushion block 8 made of a non-magnetic material is welded on the inner circle of the stator pressing ring 4, the adjusting cushion block 2 is installed between the support ring 1 and the boss cushion block 8 and located at the groove 6, the glue dipping polyester felt 5 is padded between the support ring 1 and a stator winding 7, and the stator winding 7 and the support ring 1 are bound and fixed through the binding rope 3.
The stator pressing ring is additionally provided with the boss cushion block as a radial supporting point, the gap between the boss cushion block and the supporting ring is filled by the adjusting cushion block, the supporting ring is effectively supported, the end part of the stator winding is further supported, the stator winding and the supporting ring are bound into a whole through the binding rope, and the rigidity strength of the end part of the stator winding is effectively improved, and the capability of bearing the electromagnetic force under an accident is enhanced.
Finally, the scope of protection of the present invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
