Abstract
Stator core through screw rod insulation system.Existing casing insulation system can play insulating effect to stator core, but the insulating sleeve of fixed length is not able to satisfy the height change after core pressing operation a period of time.The utility model composition includes: core through screw rod (4), interior insulation casing (5) and external insulation casing pipe (6) are successively cased with outside the core through screw rod from inside to outside, elastic parts (10) are provided between the interior insulation casing and the core through screw rod, the elastic parts includes fixing pipe (9), there are ladder circle annular groove (7) inside the fixing pipe, the step ladder circular ring trench bottom is placed with main spring (8), the ladder circle annular groove top is provided with one group of auxiliary spring (11) being evenly arranged, the auxiliary spring lower part is fixedly connected with the main spring, the auxiliary spring top is fixedly connected with the interior insulation casing.The utility model is used for stator core through screw rod insulation system.
Description
Technical field:
The utility model relates to a kind of stator core through screw rod insulation systems.
Background technique:
As hydrogenerator pool-size is increasing, stator core length is also increasingly longer, for using core through screw rod
For the stator of compression, the insulation of iron core core through screw rod is more and more important, and existing casing insulation system can be to stator core
Insulating effect is played, but there are still problems, such as: the insulating sleeve of fixed length is not able to satisfy iron core and compresses operation a period of time
Height change afterwards；Insulating sleeve need to be according to the actual height of iron core with length is cut, to meet insulation performance when building site is installed
It is required that the lap of splice of casing and insulating washer need to be increased, insulating washer is caused to thicken, core through screw rod lengthens, casing installation length
Degree is prepared fairly cumbersome.
Utility model content:
The purpose of this utility model is after the existing insulating sleeve of solution is not able to satisfy iron core compression operation a period of time
The problem of height change, provides a kind of stator core through screw rod insulation system that can adapt to iron core height change.
Above-mentioned purpose is realized by following technical scheme:
A kind of stator core through screw rod insulation system, composition include: core through screw rod, outside the core through screw rod by interior and
It is successively cased with interior insulation casing and external insulation casing pipe outside, is provided with bullet between the interior insulation casing and the core through screw rod
Property component, the elastic parts includes fixing pipe, has ladder circle annular groove, the step ladder circular ring inside the fixing pipe
Trench bottom is placed with main spring, and the ladder circle annular groove top is provided with one group of auxiliary spring being evenly arranged, the auxiliary spring
Lower part is fixedly connected with the main spring, and the auxiliary spring top is fixedly connected with the interior insulation casing.
The utility model has the advantages that
1. being cased with interior insulation casing on the utility model core through screw rod and for pushing interior insulation casing to move up or move down
Elastic parts is cased with external insulation casing pipe on interior insulation casing, and auxiliary spring upper end is fixedly connected with interior insulation casing, interior insulation casing
Top is contacted with insulation board, and elastic parts can compensate for iron core height change and require the length variation of entire insulating sleeve, is fitted
It answers iron core to compress the height change after operation a period of time, interior insulation casing top is always maintained at and is connect with insulation board
Touching ensures insulation performance.
2. the elastic parts of the utility model selects the form of main spring and the combination of one group of auxiliary spring, auxiliary spring is played pair
The effect of the support of interior insulation casing, main spring are supported the combination of auxiliary spring and interior insulation casing, and major-minor spring can be with
Replacement is supported, and can preventing that only main spring works long hours by way of this combined support, that support can occur is unstable
Lead to the case where cannot be guaranteed insulation performance with flexibility decrease.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the top view of elastic parts；
In figure: 1, locking nut；2, pressing plate；3, insulation board；4, core through screw rod；5, interior insulation casing；6, external insulation casing pipe；
7, ladder circle annular groove；8, main spring；9, fixing pipe；10, elastic parts；11, auxiliary spring.
Specific embodiment:
Embodiment 1:
A kind of stator core through screw rod insulation system, forming includes: core through screw rod 4, by interior outside the core through screw rod
And it is successively cased with interior insulation casing 5 and external insulation casing pipe 6 outside, it is arranged between the interior insulation casing and the core through screw rod
Flexible component 10, the elastic parts include fixing pipe 9, have ladder circle annular groove 7 inside the fixing pipe, described
Step ladder circular ring trench bottom is placed with main spring 8, and the ladder circle annular groove top is provided with one group of auxiliary spring 11 being evenly arranged, institute
The auxiliary spring lower part stated is fixedly connected with the main spring, the auxiliary spring top and the fixed company of the interior insulation casing
It connects.
Core through screw rod upper and lower ends are cased with insulation board 3 and pressing plate 2 respectively, end installation locking nut 1, and the two of core through screw rod
End is provided with locking nut, can prevent insulation board in use process from loosening, and ensures insulation stability.
The upper and lower ends of core through screw rod are cased with pressing plate, and pressing plate can compress insulation between locking nut and insulation board
Plate further prevents insulation board to loosen, and improves insulation stability.
Interior insulation lantern ring and external insulation casing pipe are all stairstepping, and the difference in height at the ladder of the two is the one of external insulation casing pipe
Half, it is ensured that interior insulation casing has enough movement travels, and fixing pipe lower part is fixed with insulation board, and external insulation casing pipe lower part is same
Sample is fixed with insulation board.
