Embodiment 1

[0034] A main insulation structure for the stator coil of an F-class high-voltage motor. It adopts the vacuum pressure impregnation insulation method of the less-adhesive full-impregnation type insulation stator, and wraps it with less-adhesive powder mica tape. Composite insulation structure of vacuum pressure impregnation process; its feature is that the epoxy resin of the insulation structure of the motor vacuum pressure impregnation process contains unsaturated bonds, which is a synthetic unsaturated epoxy ester resin. After diluting with active diluent, it can be obtained Low-viscosity, high-permeability, and wide-ranging impregnation insulating resin. This fully impregnated insulating resin containing unsaturated bonds has good compatibility with epoxy glass powder mica less adhesive tape. Optional, the insulation structure of the less glue vacuum pressure impregnation process composed of the two can adapt to the requirements of the insulation structure of 3KV, 6KV and 1...

Abstract

The invention adopts a dry mica tape whole impregnation type VPI (vacuum pressure impregnation) insulation process for stator. It comprises: binding up with dry mica tape; after cog leaves the production line, the whole rotator is impregnated with solventliss epoxy in vacuum pressure condition to form a composite insulation structure of VPI process. It features: the epoxy of the insulation structure contains unsaturated bond, and after adding reactive diluent, the whole impregnation insulation epoxy with low viscosity, hypertonicity and wide adaptation is obtained.

Description

technical field [0001] The invention relates to an insulating structure of a high-voltage motor vacuum pressure full impregnation process and a preparation method thereof. The insulating structure comprises a high-pressure solvent-free impregnating resin and a less-adhesive glass powder mica tape. It is mainly used for the main insulation of the stator coil of the F-class high-voltage motor vacuum pressure immersion process, and can also be applied to the insulation of other levels of stator coil immersion process. Background technique [0002] The stator coil (main insulation) of high-voltage motors is divided into less-glue whole-impregnation insulation and multi-glue molded insulation in terms of technology. The less-adhesive integral impregnation type insulation is wrapped with less-adhesive powder mica tape, and the whole stator is impregnated with solvent-free insulating resin under vacuum pressure after the blank is off-line; the multi-adhesive molded insulation is wr...
