Title: METHOD FOR PRODUCING INSULATING STRUCTURE, INSULATING STRUCTURE, AND ROTATING ELECTRICAL MACHINE
Abstract:
This method for producing an insulating structure for covering the outer surface of an object to be insulated is provided with: a winding step (S02) in which a main insulating tape is wound around the outer surface of the object to be insulated; a spraying step (S03) in which nanoparticles are sprayed on the outer surface of the wound main insulating tape; a vacuum drawing step (S06) in which the object to be insulated is subjected to vacuum drawing; and an impregnation step (S07) which is performed after the vacuum drawing step, and in which a macromolecular polymer for impregnation is injected into the object to be insulated, to impregnate the object to be insulated therewith. The spraying step may involve spraying microcapsules which have the nanoparticles accommodated therein, said nanoparticles being accommodated in the microcapsules so as to be capable of being released until the impregnation step.
