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

Abstract

Disclosed are a process equipment and a method for sealing and curing a liquid filler of a motor armature after impregnation. The curing device comprises: an airflow supply apparatus; and an armature end portion choke apparatus provided below the motor armature with the liquid filler impregnated and comprising an annular piston capable of reciprocating vertically. The annular piston is provided with multiple air inlet channels. A first airflow received from the airflow supply apparatus is impacted to an armature end portion of the winding on the below from down to up by means of the inlet channel so as to form airflow sealing of the armature end portion and prevent the liquid filler from flowing out of an axial gap and dripping.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a sealing and curing process and process equipment after impregnation of liquid fillers for motor armatures, more specifically, the present invention relates to a 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. Such as Figure 1-3 As shown, the stator motor armature 100 includes a stator core 10 and a winding 20, the stator core ...

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
