Abstract

The invention discloses a stator core winding of a high-voltage generator. The stator core winding comprises a front pressing ring, a rear pressing ring and a stator core, wherein the stator core is arranged between the front pressing ring and the rear pressing ring and formed by stacking a plurality of punching sheets, the punching sheets are made of cold rolling silicon steel sheets, and a stator winding is wound on the stator core. A tooth slot of the stator core is of a taper slot structure, the stator winding is a forming lap winding with the 2 / 3 pitch, and a plurality of reinforcing ribs are welded and fixed to the periphery of the stator core. By the adoption of the stator core winding of the high-voltage generator, harmonics can be effectively reduced, third harmonic voltages can be effectively eliminated, and waveform distortion of the voltages are improved; in parallel operation, large neutral harmonic currents can be restrained, and neutral voltages to earth are small; the strength of the end portion of the stator winding is enhanced, and the stator winding is not prone to deforming.

Description

technical field

[0001] The invention relates to a high-voltage generator, in particular to a stator core winding of a high-voltage generator. Background technique

[0002] Due to the large-scale and energy-saving requirements of modern industry, large and medium-sized high-voltage asynchronous motors and high-voltage synchronous motors are widely used in petroleum, chemical, power station, waterworks, mining and metallurgical enterprises to drive water pumps, fans, air compressors and pulverizers. . The reason is that large and medium-sized high-voltage motors have a large ratio, and medium-sized low-voltage motors have obvious advantages in capacity, and are more efficient and energy-saving. High-voltage motors can be directly connected to 10kV or 6kV power grids without the need for high-voltage and low-voltage transformers to change to 400V (or 380V) power supply. The equipment investment is small, the line loss is small, and the cross-sectional area of ​​the distributio...
