Abstract
The utility model discloses an insulation structure of a generator rotor winding, which comprises a polyimide film insulating layer wrapped on the outside of the naked wire of the rotor winding, a glass fiber insulating layer wrapped on the outside of the polyimide film insulating layer, and a vacuum paint dipping insulating layer wrapped on the outside of the glass fiber insulating layer. According to the technical scheme of the utility model, the insulation structure comprises the polyimide film insulating layer, the glass fiber insulating layer and the vacuum paint dipping insulating layer, thus is better in voltage withstanding strength, bending strength and tensile strength.
Description
Technical field
The utility model relates to generator, especially the insulating mechanism of generator amature coiling.
Background technology
The insulation system of the generator amature coiling of prior art is in coiling, whenever forms around the deposited one deck quick-drying paint of one deck.During coiling bottom coil, the radius of turn at coil two ends is less, and naked copper the crack appears and in the insulating varnish of enamelled wire easily in the shaping.Though also there is the hidden danger of turn-to-turn short circuit and layer short circuit in often mopping.When generator was for subsequent use, the most of time motor did not turn round, and then produced galvanic corrosion, made insulation damages place local overheating, constantly enlarged turn-to-turn and the layer insulation of damaging winding, caused at last turn-to-turn and layer short circuit, until shorted to earth, motor damage.This type of rotor winding insulation fault accounts for the generator total failare more than 50%.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of generator amature coiling insulation system, and good insulation preformance can effectively reduce the fault that generator causes because of the coiling insulation.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of generator amature coiling insulation system, described insulation system consists of by being wrapped in the outer polyamide film insulating barrier of rotor winding bare wire, being wrapped in the outer ferry glass insulation layer of described polyamide film insulating barrier and being wrapped in the outer vacuum paint dipping insulating barrier of described ferry glass insulation layer.
As improvement, described coiling bare wire is flat type copper wire.
The beneficial effect that the utility model compared with prior art brings is:
Insulation system with polyamide film insulating barrier, ferry glass insulation layer and vacuum paint dipping insulating barrier has better proof voltage intensity, bending strength and tensile strength; During the wound rotor coil, utilize insulation system to wrap rotor winding first, and then be wrapped in the rotor core, manufacturing process is simple.
Description of drawings
Fig. 1 is the rotor winding cross-sectional view.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of generator amature coiling insulation system, described insulation system is by being wrapped in the outer polyamide film insulating barrier 2 of rotor winding bare wire 1, being wrapped in the outer ferry glass insulation layer 3 of described polyamide film insulating barrier 2 and being wrapped in described ferry glass insulation layer 3 outer vacuum paint dipping insulating barrier 4 and consist of.In order to make rotor winding have better anti-bending strength, coiling bare wire 1 adopts flat type copper wire.
Insulation system with polyamide film insulating barrier 2, ferry glass insulation layer 3 and vacuum paint dipping insulating barrier 4 has better proof voltage intensity, bending strength and tensile strength.During the wound rotor coil, utilize insulation system to wrap rotor winding first, and then be wrapped in the rotor core, manufacturing process is simple.
