Process equipment and method for sealing and curing the liquid filler of the motor armature after impregnation

Abstract

The present disclosure provides a process apparatus and method for sealing and curing the liquid filler of a motor armature after impregnating. The process apparatus comprises an airflow supply means and an armature end portion flow choke means. The armature end portion flow choke means is disposed below a motor armature impregnated with a liquid filler, and receives first airflow from the airflow supply means, so that the first airflow goes upwards to impact the end portion of the armature so as to form a pressurized seal for the end portion of the armature, so as to prevent the liquid filler on the end portion of the armature from flowing outwards from an axial gap and dripping.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to an insulation impregnation curing process and curing process equipment used for sealing and curing the liquid filler of the motor armature after impregnation, more specifically, the present invention relates to preventing liquids from flowing out from gaps in various tissue parts The sealing method and synergistic curing device. Background technique [0002] Wind energy is one of the cleanest, non-polluting renewable energy sources. Utilization of wind power generation has increasingly become the main form of wind energy utilization, and is highly valued by countries all over the world. A wind turbine is a large-scale power generation device that converts wind energy into electrical energy. [0003] As the core component of the wind power generating set, the motor includes a rotor and a stator, and the stator includes a stator core and a winding wound on the stator core....

AI Technical Summary

Problems solved by technology

[0008] Therefore, in the process of insulating the stator windings with the traditional insulation treatment process and process equipment, it is impossible to effectively prevent the liquid insulating varnish from flowing out from the notch (slot wedge) along the radial direction, and from flowing out from the slot along the axial direction. The axial ends of the winding slot flow out, resulting in insufficient filling of the insulating varnish in the stator winding and a large number of gaps, especially the small amount of paint on the surface of the ferromagnetic boundary and a thin paint layer

In the notch part, it is also difficult to form a strict sealing ring on the outer periphery of the slot wedge, resulting in a gap between the slot wedge and the silicon wafer of the core notch, and moisture and water will naturally enter the slot along the debonding gap to destroy the insulation. operation poses safety hazards
