Description

technical field

[0001] The invention belongs to the technical field of steam turbine generators of large-scale thermal power generation equipment, in particular to a large-capacity hidden-electrode sleeve-type synchronous generator. Background technique

[0002] At present, domestic generator production is dominated by small-scale low-pole generators. Due to the small power generation capacity, low energy utilization rate, low pole number, and high output voltage pole-change rate of this type of generator, it is increasingly unsuitable for modern large-scale enterprises. The requirements for power consumption and external networking have gradually developed towards large-scale high-pole generators. However, the large-scale generators in the prior art generally have the following problems:

[0003] (1) Due to the large power generation capacity of large generators, the components such as stator and rotor windings, main shaft bearings, and excitation systems generate a lot of...
