Description
Technical field
A kind of gas turbine generator structure member is the utility model is related to, is that a kind of 660MW double water innercooling electric generators are determined
Sub- end large conic ring.
Background technology
Double-water internal cooling product capacity reaches 300MW within 1974, afterwards applied to Qinshan Phase II NPP, Pakistan core
Electricity.Existing 660MW double water innercooling electric generators stator end fixture, unreasonable structure, vibration-resistant property is undesirable, influences to generate electricity
The service behaviour of machine, service life are short.
The content of the invention
The purpose of this utility model is to provide a kind of good 660MW double water innercooling electric generator stator ends of using effect big
Conical ring.
Technical solution of the present utility model is：
A kind of 660MW double water innercooling electric generators stator end large conic ring, it is characterized in that：Including tapered annular body, conical ring
The inwall of shape body is provided for the multi-layer groove of resin rope lay, and screw rod perforation and thread bush are set on taper annular solid body wall；Cone
The taper of shape ring bodies is 15 ~ 35 °；The taper of tapered annular body is 17 ~ 35.55 °；
The polytetrafluoroethylene (PTFE) cotton layer of phorogenesis has been pasted with the small end periphery of tapered annular body.
The small end inner diameter of tapered annular body is 1726mm, and small end external diameter is 1777mm, and the big end internal diameter of tapered annular body is
2242.4mm, big end external diameter is 2369mm；The height of tapered annular body is 908.7mm；The external wall middle part of tapered annular is set
42 arc pits are put, 42 arc pits are annularly evenly distributed along conical ring ring bodies outer wall, and arc pit bottom is away from small end
Vertical range is 410.7mm.
The alkali-free glass fibre fabric of the tapered annular body including impregnating resin and impregnating resin it is glass chopped
Felt replaces the complex of compound composition；Polyester layer is set in the periphery of the complex, epoxy resin is set in polyester layer periphery
Layer.
The utility model is rational in infrastructure, can be subjected to the effect of electromagnetic vibration power for a long time, its coefficient of thermal expansion and end turn
Coefficient of thermal expansion be adapted, unnecessary stress will not be produced and loosen winding, can effectively suppress electromagnetic vibration power and suddenly it is short
Active force under road, stator end part can be effectively avoided to resonate.As structure member, also created for winding overhang and miscellaneous part
One is made radially, axially and the stabilized platform that axially fastens.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the utility model 660MW double water innercooling electric generator stator end large conic rings.
Fig. 2 is the ringwall structure schematic diagram of the utility model 660MW double water innercooling electric generator stator end large conic rings.
