Rolling type rotate baking method and device of high-rating generator

Abstract

The invention relates to rolling type rotate baking method and device of a high-rating generator. The high-rating generator is placed on a rolling type rotate baking device, and is baked through rolling type rotation of the rolling type rotate baking device. The rolling type rotatiton is characterized by placing the generator to be dried in the rolling type rotate baking device with a rotatable part, installing the generator to be dried on the rotatable part of the rolling type rotate baking device to together rotate in the rolling type rotate baking device when a rotate shaft of the rotatable part of the rolling type rotate baking device rotates, laying heating elements on a fixing part of the rolling type rotate baking device according to a rotate space of the rotatable part of rolling type rotate baking device, and drying impregnated paint of the generator to be dried through the heating elements of the fixing part of the rolling type rotate baking device when the generator to be dried rotates in the rolling type rotate baking device.

Description

technical field [0001] The invention relates to a method and device for drying a generator, in particular to a method and device for rolling and rotating a large electric locomotive (generator). It is mainly used for drying paint of large traction motors for electric locomotives. Background technique [0002] Generally, during the production process of generators, in order to ensure insulation, impregnation insulation treatment is required, that is, the motor is dipped in insulating varnish, then taken out, and dried to make it meet the required insulation requirements. For general small motors, it is relatively easy to dry after impregnating insulating varnish, and various methods can be used for drying treatment; but for large generators (such as traction motors of electric locomotives), due to the huge structure of the motor itself, so There are not many drying methods available. Existing large-scale (generator) baking devices are all static baking devices. During the b...

For general small motors, it is relatively easy to dry after impregnating insulating varnish, and various methods can be used for drying treatment; but for large generators (such as traction motors of electric locomotives), due to the huge structure of the motor itself, so Not many drying methods available

Existing large-scale (generator) baking devices are all static baking devices. During the baking process, the motor is always in a stationary position in the baking room. In this way, the paint liquid will always be in a top-to-bottom flow. The tendency is to flow, the loss of paint liquid is more, the direction of paint liquid loss is consistent, and the paint film on the surface of the product is uneven; and because the temperature in the baking room is not exactly the same, there is a dead angle in the temperature during the drying and curing process, which affects the impregnation. The filling rate and curing effect of the paint greatly affect the insulation performance of the motor product

So the effect is not very ideal, so it needs to be further improved
