Abstract
The utility model relates to a part of a generator set, in particular to a reliable ground insulation structure of a magnetic pole coil, which is used for mainly solving the technical problems of being shorter in ground creep distance of the magnetic pole coil in the generator, poor in insulation reliability, intensity and integrity of a coil, incapable of preventing dust and pollution and the like in the prior art. The reliable ground insulation structure of the magnetic pole coil disclosed by the utility model comprises a magnetic pole iron core (1); a magnetic pole coil (2) is wound on the magnetic pole iron core; the structure is characterized in that insulation flanges (3) are connectedly arranged at contact positions among upper and lower ends of the magnetic pole coil (2) and the magnetic pole iron core (1); and a closed type insulation plate (4) is arranged at the contact position between the magnetic pole coil and the magnetic pole iron core.
Description
Technical field
The utility model relates to a kind of parts of generating set, especially relates to a kind of reliable pole coil insulation against ground structure.
Background technology
Homemade hydraulic generator unit extensively adopts vertical structure, and the vertical hydrogenerator group is driven by mixed-flow or axial flow turbine usually, and vertical structure can be divided into suspension type and umbrella formula again.Chinese patent discloses a kind of self-contained mixed flow vertical hydrogenerator group (Granted publication number: CN2610111); It comprises generator, the hydraulic turbine and draft tube; Generator is installed in hydraulic turbine top through generator stand, and with the shared main shaft of the hydraulic turbine, draft tube is installed in hydraulic turbine below; The hydraulic turbine is made up of ring, stator, seat ring and spiral case, blade controlling organization, top cover, top cover seal ring, seal receptacle, packing and packing gland and drainage pipe under ring, the wicket gates on runner, the wicket gates; On the wicket gates ring, wicket gates down ring be positioned at the runner outside, seat ring and spiral case are positioned at ring on the wicket gates, the wicket gates outside of ring down, stator is between ring, wicket gates encircle down on the wicket gates, the edge circumferentially is uniformly distributed with; The runner of the hydraulic turbine is connected through tapered sleeve, housing screw and generator shaft; Constitute outer draining device by top cover seal ring, top cover and drainage pipe; Has the sealing teeth groove between top cover seal ring and runner; Have last sheaf space between top cover seal ring and top cover, the upper end of drainage pipe communicates with the outside of last sheaf space through top cover, and the lower end of drainage pipe communicates with the upper end of draft tube; The blade controlling organization is made up of guide vane teunnion, rotation connecting lever, connecting rod rotating shaft, connecting rod; Guide vane teunnion is connected with stator is vertical, and the rotation connecting lever is radially external, and inner and guide vane teunnion is hinged, and the outer end is provided with two connecting rod rotating shafts, in the adjacent connecting rod rotating shaft of two adjacent rotation connecting levers connecting rod is housed, and makes its line with two guide vane teunnions equal and parallel; All stators of the hydraulic turbine all link to each other through guide vane teunnion, rotation connecting lever, connecting rod in twos.But the creepage distance over the ground of the pole coil in this generator is less, and the insulating reliability of coil, intensity and globality are relatively poor, and can't play dustproof, antipollution effect.
The utility model content
The utility model provides a kind of reliable pole coil insulation against ground structure; It mainly is that the pole coil creepage distance over the ground that solves in the existing in prior technology generator is less; The insulating reliability of coil, intensity and globality are relatively poor, and can't play the technical problem of dustproof, antipollution effect etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of reliable pole coil insulation against ground structure of the utility model; Comprise pole core; Be wound with pole coil on the pole core; The contact position of two ends and pole core all is provided with insulating flange about the described pole coil, and the contact position of pole coil and pole core pole body is provided with the sealed insulating plate.The two ends of pole coil are provided with high-intensity insulating flange, can guarantee can not leak electricity when it is installed.The thickness of sealed insulating plate can be 2-3mm, can not only play the effect of insulation, can also play dustproof, antipollution effect.
As preferably, the described pole coil insulating flange at two ends and the contact position of pole core pole body up and down is provided with the insulation seamed edge.The insulation seamed edge can adopt the Nomex paper of import, can eliminate the creepage passage that the gap between flange and the pole body produces.
As preferably, the gap location of described pole core and pole coil, insulating flange is filled with F level epoxy resin.The gap location that produces during the pole coil assembling can be coated with F level epoxy resin and adopt hot press forming technology to fill, thereby has improved the intensity and the globality of pole coil.
Therefore, the utility model has improved pole coil creepage distance over the ground, has guaranteed the reliability of coil insulation, has good integrity, structured size, characteristics such as dustproof, anti-pollution, simple and reasonable for structure.
