Description

technical field [0001] The invention relates to the field of performance simulation analysis of large-scale generator wire rods, in particular to a multi-factor optimization design method for the surface electric field of motor wire rods. Background technique [0002] With the continuous development of my country's industry, the society's demand for electricity has increased significantly, which has directly led to an increase in the demand for large generators. The running stability of the generator is greatly affected by the insulation, especially at the end of the stator bar of the generator, there will be obvious electric field concentration phenomenon, which is mainly manifested as corona discharge. In order to make the electric field distribution on the surface of the motor bar uniform, it is necessary to consider various influencing factors in the design, such as the length of each section of the anti-corona layer, the resistivity of each section of the anti-corona la...
