Abstract
A rotor coupling having insulated structure which can assuredly prevent galvanic corrosion of beating members, rotors and the like which is caused by shaft voltage, is provided in a shaft system that requires insulation. A generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine. The rotor coupling having insulated structure is employed in power generating equipment in which a generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine, a generator rotor and a rotating machinery rotor are connected, a first grounding electrode is provided to the steam turbine rotor, and a second grounding electrode is provided to the generator rotor, wherein both the rotors between the generator and the steam turbine are connected in an electrically insulated state.
