Value calculation APP for big motor stator line rod end part model

Abstract

The invention discloses an electric field calculation APP for a big motor stator line rod end part model. A method comprises the steps of 1, performing parameterization modeling on the end part of a big motor end part (the parameterization control on the end part wire core cross section dimension, the three-dimensional twisting angle of an end model, the thickness of an insulation layer and an anti-halation layer, and the length of each section of the three-section type anti-halation layer is realized); 2, performing finite element numerical simulation analysis on the model built through parameterization; adding corresponding materials on the model; performing mesh generation; using a frequency domain solver at 50hz for electric field calculation; solving the corresponding electric potential and electric field and the consumed distribution diagram; 3, building an end electric field finite element calculation APP according to the process; performing end part anti-halation layer electric field and electric potential and loss solving through changing the dimension parameter, the material parameter and the test parameter of a model. The electric field calculation APP has the advantages that the time consumed by development personnel in the modeling and simulation process can be effectively saved; the design efficiency is effectively improved.

Description

technical field [0001] The invention is mainly used in the field of high-voltage insulation, and mainly develops a numerical calculation APP for the end model of the stator bar of a large motor. Background technique [0002] For high-voltage motors, there is often an electric field concentration at the exit of the stator bar, and an anti-corona structure can be applied at the end to achieve the effect of homogenizing the electric field and effectively protect the insulation. With the popularization of computers, simulation can often be used to simulate the operating status of products in the actual environment before engineering practice. At present, among various numerical calculation methods, the calculation of finite element method is the most accurate, but because the application of simulation software based on finite element requires high theoretical knowledge and skills of the operator, it is difficult to popularize it. It is difficult to obtain design data before des...
