Description

Technical Field

[0001] The present invention relates to the technical field of hydro-generators, and particularly to a pole inter-pole support device suitable for cooling the pole coil. Background Art

[0002] The speed of pumped-storage units is high and the centrifugal force is large. To ensure the safety of rotating components, a reliable support device needs to be set between the poles. In the prior art, a support device is often installed between the poles by using a retaining band plus a setscrew or an inter-pole insulating support block. Due to the difficulty in grasping the accuracy of the gap between the setscrews and the gap between the inter-pole support block and the pole coil, if it is too large, the good supporting effect of the setscrew cannot be exerted, and if it is too small, it may lead to large thermal stress. Therefore, the installation reliability of the support device is poor.

[0003] Chinese patent document with the publication number of CN205595925U and the publication date of September 21, 2016 discloses an insulating split-type inter-pole support device suitable for the support of thin steel plates of a hydro-generator, which is characterized in that: it is composed of a slotted single-piece insulating support block, a thin steel plate tab, a first bolt, a nut, a cylindrical pin, a second bolt, a dove-tail block and a set screw. Multiple thin steel plate tabs are stacked together and placed in the slots of two slotted single-piece insulating support blocks, and are tightened into one body with the first bolt and the nut, and are installed in the middle of two adjacent poles to support the two adjacent poles. The thin steel plate tab and the dove-tail block are tightened with the second bolt, and the cylindrical pin is placed in the pin holes of the thin steel plate tab and the dove-tail block to bear the centrifugal force. The dove-tail block is placed in the dove-tail groove of the yoke, and is pushed into the hole processed on the yoke with the set screw for axial limit and radial tightening.

[0004] The insulating split-type inter-pole support device suitable for the support of thin steel plates of a hydro-generator disclosed in this patent document has the support tabs of the insulating split-type inter-pole support device suitable for the support of thin steel plates of a hydro-generator formed by stacking multiple high-strength thin steel plates, and multiple thin steel plate tabs and the slotted single-piece insulating support block are combined into a whole with bolts and nuts. During the rotation of the unit, the support tab bears the radial force of the insulating support block to ensure the safe and stable operation of the unit. However, the stress-bearing capacity of the insulating support block is limited, and it is easy to produce layered cracking, which affects the overall stiffness of the inter-pole support device and is not conducive to improving the heat dissipation efficiency of the pole surface, and the applicability is poor. Summary of the Invention

[0005] In order to overcome the above defects of the prior art, the present invention provides a pole inter-pole support device suitable for cooling the pole coil, which not only improves the stiffness of the inter-pole support device, but also is conducive to improving the heat dissipation efficiency of the pole surface, and has good applicability.

[0013] Both the first elastic member and the second elastic member are located in the middle of the inter-pole baffle.

[0014] Both the first elastic member and the second elastic member are symmetrically arranged along the inter-pole baffle.

[0015] The disc spring retaining ring is fixedly connected to the inter-pole baffle by welding.

[0021] The beneficial effects of the present invention are mainly manifested in the following aspects:

[0022] 1. Compared with the prior art, the present invention not only improves the stiffness of the inter-pole support device, but also is beneficial to improving the heat dissipation efficiency of the pole surface, and has good applicability.

[0023] 2. In the present invention, a wedge-shaped key is provided on the magnetic yoke, and the interpolar baffle is fixed to the interpolar T-tail groove of the magnetic yoke through the wedge-shaped key. The interpolar baffle is fixed by the wedge-shaped key, which can improve the fixing reliability of the interpolar baffle and ensure the safety and reliability of the supporting device.

[0024] 3. In the present invention, the inter-pole baffle is a hollow structure and is located between any two adjacent magnetic poles, which can further compress the distance between the inter-pole baffle and the magnetic pole coil, thereby increasing the wind speed on the surface of the magnetic pole coil and increasing the elastic reserve of the supporting device.

[0025] 4. The present invention improves the overall rigidity of the inter-pole support device and can better adapt to the thermal expansion of the pole coil, thereby ensuring that the pole coil is both firmly fixed and can match the thermal deformation.

[0026] 5. In the present invention, the disc spring pressure ring and the inter-electrode baffle are fixed by welding, which can ensure the stability of the entire supporting device.

[0028] 7. In the present invention, the inter-electrode baffle is formed of an aluminum alloy in one piece, and the hollow structure of the inter-electrode baffle is diamond-shaped, which can not only provide good support, but also provide sufficient elastic reserve for the entire device.

[0029] 8. In the present invention, the disc spring is a laminated structure, which can improve the supporting stiffness and is suitable for magnetic poles with large lateral force of the magnetic pole coil and small deformation.

[0030] 9. In the present invention, the disc spring is of a coupled structure, which can increase the deformation reserve and is suitable for magnetic poles with small lateral force of the magnetic pole coil and large deformation.

The size of the center column is matched with the size of the center circular hole of the disc spring, which can avoid the risk of the disc spring falling out when the installation quality is poor. The spherical surface of the top screw end avoids the problem of poor plane contact, increases the contact range between the center circular hole of the disc spring and the top screw, and makes the support more reliable.
