Abstract
The utility model relates to an improved structure of insulation layer between magnetic pole coil and iron core of generator rotor. The utility model is characterized in that: the upper and lower ends of the insulation layer are provided with an edge turning outward 90 degree separately. The upper and lower edges are integrated together with the insulation layer, and molded through hot pressing. The utility model eliminates the creeping channel of coil and magnetic pole iron core at the insulation pole of original structures. Meanwhile, the creeping distance at the external side of coil is increased with wide-edge insulated filler plate or coil wrapped with insulation at two ends. Therefore, the utility model has the advantages of good integrity, high size precision, good insulation performance, etc.
Description
Technical field
The utility model belongs to machine field, and the insulating barrier that relates in particular between a kind of power generator rotor magnetic pole coil and the iron core improves structure.
Background technology
The insulating barrier 11 of the insulating pad up and down of generator rotor core and iron core side is generally isolating construction on the market, as shown in Figure 1.Put into down earlier insulating pad during assembling, then put iron core, cover insulating pad again, at last coiling pole line circle outside the iron core that is insulated layer, insulating pad encirclement up and down.This structure, at insulating barrier with will form a slit up and down between the insulating pad, operation year long afterwards can be tied ash, causes between pole coil and the iron core knot ash creepage, and the insulation resistance of magnetic pole can seriously descend.
Summary of the invention
The utility model provides a kind of creepage passage that can eliminate pole coil and pole core, and the power generator rotor magnetic pole coil and the insulating barrier between the iron core that increase the insulation property of pole coil improve structure.
The utility model is achieved by the following technical solution: the termination up and down of being located at the insulating barrier of iron core side is provided with to turning up 90 ° limit, and one piece is hot-forming.
Turn up 90 ° limit, insulating barrier two ends replaces original insulating pad up and down, and the slit of having eliminated iron core side insulating barrier in the original structure and having existed between the insulating barrier has up and down been stopped to produce between insulation pole body place's coil and the pole core creepage.Coil outside creepage distance adds the more creepage distances of method increase of bag insulation by adopting broadside insulating pad or coil first and last simultaneously.Have advantages such as good integrity, height dimension are accurately smooth, good insulation preformance.
Description of drawings
Fig. 1 is the structural representation of the insulating barrier between former power generator rotor magnetic pole coil and the iron core.
Fig. 2 is the structural representation that the insulating barrier between the utility model power generator rotor magnetic pole coil and the iron core improves structure.
Embodiment
Embodiment 1: the power generator rotor magnetic pole coil of present embodiment and the insulating barrier between the iron core improve structure, as shown in Figure 2, insulating barrier respectively has one to turning up 90 ° limit 2 in the termination about in the of 1, and upper and lower both sides 2 and insulating barrier 1 are integral body, and one piece is hot-forming.Not only increase the insulation property between pole coil and the iron core, also guarantee the globality of insulating barrier, make the assembling of rotor convenient, also effectively increased pole coil creepage distance over the ground simultaneously.
Claims (1)
1. the insulating barrier between power generator rotor magnetic pole coil and the iron core improves structure, it is characterized in that insulating barrier (1) is provided with to turning up 90 ° limit (2) termination up and down, and upper and lower both sides (2) and insulating barrier (1) are individual integral body, and one piece is hot-forming.
