Description
Technical field
The utility model is related to steam turbine generator technical field, and specially a kind of stator of steam turbine generator positioning bar end is exhausted
Edge structure.
Background technology
Steam turbine generator is the nucleus equipment of big power station, in recent years, it is found that many generators are leaked due to core-back
Magnetic produces stator core end and the phenomenon burnt occurs, the generator for having end defect, with the growth of run time, feelings of burning
Condition is more and more severe, or even some motors develop into the serious accident of iron core thawing, once occur iron core burnout failure, directly
Economic loss is up to more than 5,000 ten thousand RMB, and indirect economic loss will be more than 100,000,000.
Existing high-rating generator core design is unreasonable, and core-back leakage field is excessive, and positioning bar pressure difference is big.
Utility model content
The purpose of this utility model is to provide a kind of stator of steam turbine generator positioning bar overhang insulation structure possess large-scale
Generator iron-core is reasonable in design, and core-back leakage field is small, the small advantage of positioning bar pressure difference, solves high-rating generator core design
Unreasonable, core-back leakage field is excessive, the problem of positioning bar pressure difference is big.
To achieve the above object, the utility model provides following technical scheme：A kind of stator of steam turbine generator positioning bar end
Portion's insulation system, including positioning bar and silicon steel sheet, the bottom of the silicon steel sheet inner chamber are fixedly connected with front insulation spacer, described
Both sides at the top of the insulation spacer of front have been fixedly connected with side formula insulation spacer, and the bottom of the positioning bar extends to silicon steel sheet
Inner chamber.
It is preferred that, the bottom of the positioning bar is contacted with the tight of front insulation spacer.
It is preferred that, the both sides and the junction of side formula insulation spacer at the top of the front insulation spacer are solid by fixture
Connect calmly, and two side formula insulation spacers are centrosymmetric on positioning bar.
It is preferred that, the outside of silicon steel sheet is extended at the top of the side formula insulation spacer and is in close contact with positioning bar.
It is preferred that, the outside of the side formula insulation spacer and the inwall of silicon steel sheet are in close contact, the inner chamber of the silicon steel sheet
It is trapezoidal.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is solved big by setting positioning bar, side formula insulation spacer, front insulation spacer and silicon steel sheet
Generator core design is unreasonable, and core ends back leakage field is excessive, and positioning bar pressure difference causes greatly what end iron core burnt to ask
Topic, the stator of steam turbine generator positioning bar overhang insulation structure possesses high-rating generator core design rationally, each is positioned
Muscle end and the contact site of silicon steel sheet are completely cut off with epoxy insulation pad, and such galvanic circle cannot be re-formed, and be prevented
Back leakage field is led to the defect of iron core burn, is worthy to be popularized.
2nd, the utility model plays a part of insulation by setting side formula insulation spacer and front insulation spacer, it is to avoid electricity
Use to user is made troubles, and by the way that the inner chamber of silicon steel sheet is set in echelon, conveniently blocks positioning bar, it is to avoid positioning bar
Come off from silicon steel sheet, the use to user is made troubles.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 positioning bar, 2 side formula insulation spacers, 3 front insulation spacers, 4 silicon steel sheets.
Embodiment
