Abstract
The utility model relates to an oblique stud structure of stator frame of hydraulic generator. The radical arrangement direction of the stud of a stator frame and the radius direction of the stator form a certain included angle and form the oblique stud of the stator frame; the installation direction of the oblique stud is opposite to the rotating direction of a rotor and forms a retroverted structure. The oblique stud structure of stator frame of hydraulic generator not only can guarantee the stator frame to be reliably installed, but also can effectively reduce the acting force of electromagnetic torque on the frame generated by the rotation of the rotor. Through detailed analysis and calculation, the oblique stud structure of the retroverted stator frame can fully meet the requirements on rigidity, intensity and vibration.
Description
Technical field
The utility model relates to the oblique stud structure of a kind of hydraulic generator stator support.
Background technology:
Prior art as shown in Figure 1, tiltedly support arm structure generally adopts electromagnetic torque and oblique stud direction uniform structure, but still has core lamination because variations in temperature causes the problem of warpage, adopts this structure to reduce the coefficient of safety of warpage unshakable in one's determination.
Summary of the invention
The purpose of this utility model provides a kind of can effectively reducing because thermal stress acts on the thermal deformation that support produces, and can stop the oblique stud structure of hydraulic generator stator support of stator-core lamination warpage simultaneously.The technical solution of the utility model is: the oblique stud structure of a kind of hydraulic generator stator support, the out frame stud its radially placement direction and stator radial direction form an angle and form the oblique stud of out frame, tiltedly the stud installation direction is opposite with the rotor direction of rotation and form the BI structure.Use oblique stud structure and can make support have enough elasticity, allow the free wxpansion of thermal deformation lower support, guarantee the annulus concentricity and the stability of stator.Simultaneously, tiltedly the stud structure also has specific tangential rigidity, can adapt to static state and dynamic torque.When the out frame thermal expansion, tiltedly stud can be towards the direction deflection of mechanical resistance minimum, the ring flat-plate deflection simultaneously that oblique stud is connected, thereby the concentricity of assurance ring flat-plate.Under the effect of out frame at electromagnetic torque, tiltedly stud can be decomposed into the active force of electromagnetic torque the component of both direction, thereby improves the stability of whole generator.Content of the present utility model is to adopt the BI structure in the installation process of hydraulic generator stator support, effectively reduces the active force of electromagnetic torque to out frame.And reduce the generator thermal stress that thermal expansion produces support in running.The original structure electromagnetic torque is consistent with the incline direction of the oblique stud of support to the action direction of support, though can effectively reduce because the frame deformation that thermal stress causes, but the field ring plate wave degree that produces exerts an influence to the warp stability of iron core, adopting the utility model is the BI structure, not only can inherit the advantage of FC structure, and can eliminate field ring plate wave degree greatly to the influence of warp stability unshakable in one's determination.Adopt oblique stud structure can also regulate the out frame natural frequency easily, avoid dangerous resonance frequency scope.
Description of drawings
Fig. 1 is existing oblique stud installation direction of hydraulic generator stator support and rotor mounting structure figure.
Fig. 2 is oblique stud direction of the utility model hydraulic generator stator support and rotor mounting structure figure.
Embodiment:
The oblique stud structure of a kind of hydraulic generator stator support as shown in Figure 2, the out frame stud its radially placement direction and stator radial direction form an angle and form the oblique stud 1 of out frame, tiltedly stud installation direction and rotor direction of rotation 2 are opposite and form the BI structure.The installation that can guarantee out frame like this is reliable, can effectively reduce again because rotor rotates the active force of the electromagnetic torque of generation to support.Through detail analysis and calculating, the oblique stud structure of BI out frame can satisfy stiffness and vibration requirement fully.The utility model be the oblique stud structure Design of generator unit stator once than quantum leap.Because adopt the hypsokinesis structure, under generator operating condition, electromagnetic torque will reduce greatly to the active force of support, the stability to support also improves a lot simultaneously.
Claims (1)
1. oblique stud structure of hydraulic generator stator support, it is characterized in that: the out frame stud its radially placement direction and stator radial direction form an angle and form the oblique stud of out frame (1), tiltedly the stud installation direction is opposite with rotor direction of rotation (2) and form the BI structure.
