Abstract
The invention relates to a support structure for a combined cushion block of coils at the rotor end of a steam turbine generator. The combined cushion block comprises a large cushion block and a small cushion block, wherein the large cushion block is placed between the coils at the rotor end and used for supporting the coils at the rotor end, the top of the large cushion block is provided with a notch, the small cushion block is placed in the notch of the large cushion block and can be moved up and down for adjusting, and the upper plane of the small cushion block keeps flush with the coils at the rotor end. The support structure for the combined cushion block of the coils at the rotor end of the steam turbine generator is simple and safe and reliable to use; due to the fact that the combined cushion block with adjustable height is arranged, the coils at the rotor end can be fully supported and fixed, and it will not occur that the coils at the rotor end are not provided with the cushion block for supporting. In this way, the overall rigidity of a winding at the rotor end of the steam turbine generator can be enhanced, the deformation of the winding at the rotor end of the steam turbine generator can be reduced, and then it is guaranteed that the steam turbine generator runs safely and reliably.
Description
Technical field
The present invention relates to turbo-generator end coil support structure, specifically rotor of steam turbo generator end coil combined pad supporting construction, belongs to motor device technical field.
Background technology
Turbo generator is high-speed electric expreess locomotive, and rotating speed is high, and during operation, rotor oscillation is large, and centrifugal force is large.Rotor tip winding stretches out rotating shaft, when motor moves, be subject to powerful centrifugal action, deformation can be there is, if deformation is large, rotor coil turn-to-turn short circuit can be caused, coil burnout, affect the reliability service of turbo generator, so rotor tip winding wants fixation, reliable, need to adopt a kind of safe fixed form guarantee the reliable normal operation of turbo generator.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rotor of steam turbo generator end coil combined pad supporting construction is provided, it is simple in structure, safe and reliable, can strengthen the integral rigidity of rotor of steam turbo generator end winding, reduce the winding deformation of rotor of steam turbo generator end, and then guarantee turbo generator safe and reliable operation.
According to technical scheme provided by the invention: rotor of steam turbo generator end coil combined pad supporting construction, it is characterized in that: comprise retaining ring, dead ring and combined pad, described rotor end turn coils stretches out rotating shaft, combined pad is positioned between rotor end turn coils, dead ring is arranged in rotor end turn coils outside, dead ring outside is fixed with retaining ring, and dead ring is guaranteed to insulate between rotor end turn coils and retaining ring.
As a further improvement on the present invention, described combined pad comprises big cushion block and small cushion block, and described big cushion block is positioned between rotor end turn coils, with support rotor end coil; Described big cushion block top is provided with breach, and small cushion block is placed in the breach of big cushion block and can moves up and down adjusting, and on small cushion block, plane is concordant with rotor end turn coils maintenance.
As a further improvement on the present invention, in the gap of described small cushion block and big cushion block breach, be filled with terylene felt.
As a further improvement on the present invention, separated use capable of being combined or complete between described small cushion block and big cushion block.
compared with prior art, advantage is in the present invention:the present invention is simple in structure, safe and reliable, its by arrange can be Height Adjustable combined pad, making to access abundant support between rotor end turn coils fixes, the situation that there will not be rotor end turn coils not have cushion block to support, can strengthen the integral rigidity of rotor of steam turbo generator end winding, reduce the winding deformation of rotor of steam turbo generator end, and then guarantee turbo generator safe and reliable operation.
