    • The present invention provides a rotor for a rotary electric machine that suppresses the occurrence of winding disturbances in the process of winding a coil wire and has a coil field having a uniform outside diameter that is less likely to collapse.A coil field of a rotor coil is constructed by winding a coil wire having a circular cross section onto an outer circumference of a drum portion of a bobbin in multiple layers so as to make columns in each of the layers equal in number in an axial direction. Odd numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of a first flange portion of the bobbin, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of a second flange portion of the bobbin, and even numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of the second flange portion, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of the first flange portion. The gap S satisfies an expression D/4≦S≦D/2 relative to a diameter D of the coil wire.Thus, because the occurrence of winding disturbances in the process of winding the coil wire is suppressed, the coil wire can be wound into an aligned state, enabling a coil field that is less likely to collapse to be achieved, and the outside diameter of the coil field is made uniform, also preventing damage to an electrically-insulating coating resulting from contact with claw-shaped magnetic poles.

    • In a recovery type steam cooled gas turbine, dew condensation is prevented when feeding steam in a starting operation of the gas turbine, and penetration of high temperature combustion gas into a steam cooling passage is prevented. Also, residual steam is removed in the stopping operation of the gas turbine. The gas turbine (1) has moving and stationary blade steam cooling passages (4a, 4b). The steam from steam cooling pipes (9, 10) flows through these passages to cool them. The steam after cooling is recovered. In the starting operation of the gas turbine, air from a compressor (2) flows through a valve (15) and a flow rate regulator (7). Also, a portion of the air is subjected to a temperature adjustment in a temperature adjuster (5) and flows through three-way valves (11, 12) to a steam cooling passage (4a, 4b) to be discharged through three-way valves (13, 14) and a flow rate regulator valve (8) to warm the passages (4a, 4b). Also, valves (15, 16) are closed and a valve (17) is opened so that outside air or inert gas from a medium feed source (6) may flow. After the warming up operation in the starting operation, the three-way valves (11 to 14) are switched to allow the steam to flow from the pipes (9, 10) to the passages (4a, 4b) to perform cooling during regular operation. Furthermore, after the stopping operation, it is possible to purge the residual steam within the passages (4a, 4b) with air.
