Description
Technical Field
The utility model relates to the technical field of processing and manufacturing equipment, in particular to a device for assisting in insulating and curing of a generator stator winding.
Background
Generator stator winding insulation is the basic building block that makes up the generator stator winding. After braiding, transposition and gel forming, the individual strands (wires with insulating layers) forming the insulation of the stator winding of the generator are continuously wrapped with the insulating layers integrally, and solidified and formed by a certain process. The curing process of the generator stator winding insulation is critical to its final performance. Curing is the process that the uncrosslinked curing glue in the prepreg gradually forms a three-dimensional crosslinked network structure under the action of certain temperature, pressure and time, and finally the insoluble and infusible thermosetting composite material is obtained. If the temperature and pressure distribution of the product in the curing process is uneven, the uneven curing degree distribution and imperfect curing of the product may be caused, and the performance of the final product may be deteriorated.
The existing curing device is often a heating oven, and a workpiece is placed in a closed box body in the oven through a steel frame for heating and curing. The problems are: the heating oven is heated by the heating wires, high-temperature air is generated after ventilation, and the hot air is introduced into the closed box space, so that the temperature is increased, and the workpieces in the box space are heated. The temperature of the hot air in the heating oven is often far higher than the actual required temperature (i.e. the set temperature), so that the interior of the heating oven can reach the set temperature through heat exchange. The problem with this is that when hot air is blown straight to the surface, the surface temperature is much higher than desired, resulting in localized excessive cross-linking curing. While other locations of the article are not sufficiently crosslinked. Such uneven distribution of the degree of crosslinking leads to uneven stress distribution of the article, which in turn leads to increased residual stress, increased internal defects of the article, and deterioration of the final properties of the article.
