[0002] A hydroelectric generator set, also known as a "turbine generator set," is a power generation unit consisting of a turbine and its associated generator at a hydropower station. It is the primary power source for generating electricity. When water flows through the turbine, it converts water energy into mechanical energy that drives the machine's rotation; the generator, in turn, converts this mechanical energy into electrical energy for output.
[0003] The hydroelectric generator rotor is an important part of the hydroelectric generator set. When assembling the hydroelectric generator rotor, the magnetic poles need to be installed on the rotor slots. When installing the magnetic poles, a lifting device is needed.
