摘要： The present invention provides 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, in a shaft system that requires insulation in which 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 of the present invention 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.

摘要： The division wall is made up of a plurality of division wall sections forming a passage wall of high temperature gas which are connected in the direction of arrangement of blades to form a wall surface having a roughly circular cross section as a whole, a gas flow restricting structure for preventing high temperature gas from passing through a gap formed at a connecting portion between the division wall sections in the flow direction of the high temperature gas from the opening on the upstream side of the high temperature gas in the gap, or a gas flow restricting structure for preventing the high temperature gas from being embraced in the gap, for example, a sealing member formed into a prism having a T-shape cross section as a whole composed of a plane portion as a sealing portion and a projected portion for filling the gap is provided.
