摘要： A method of maintaining the housing of a reactor pressure vessel having: a reactor pressure vessel into which cooling water is introduced; a cylindrical housing which penetrates an end bracket of the reactor pressure vessel; and a circumferential weld for securing the intermediate portion of the housing to the reactor pressure vessel by welding, the method of maintaining a housing of a reactor pressure vessel comprising the steps of: remaining the cooling water in the reactor pressure vessel; preventing leakage of the cooling water in the reactor pressure vessel through the housing by sealing the housing; making the inside portion of the housing lower than the seal to be a hollow space of a gas atmosphere; heating a heat affected zone due to welding by using a heating device inserted into the hollow space from a lower portion so as to compressive-yield the inner surface of the housing in the heat affected portion upper than the circumferential weld and tensile-yield the outer surface; and cooling heated portion inside of the housing, which has been yielded, so as to tensile-yield the inner surface of the housing by using a cooling device inserted into the housing from a lower portion, whereby compressive stress is allowed to remain in the tensile-yielded portion.

摘要： In a rotary electric machine including a stator core and a stator winding received in slots of the stator core, a cooling medium baffling device is provided which comprises a cooling medium baffle plate fixed to the inner peripheral edge of one end of the stator core by mounting bolts protruding axially from the end of the stator core, wherein the circumferential position of each of the mounting bolts is displaced from the circumferential position defining the boundary between the different modes of phase currents flowing through the coils constituting the stator winding, thereby effectively eliminating generation of excessive heat due to excessive eddy current losses occurring locally at the end of the stator core.

摘要： An electric rotary machine is provided with a stator having a stator core of laminated iron plates with a given lamination thickness in an axial direction of the machine and a stator winding wound around the core and a rotor rotatably disposed inside the stator, having a rotor core and a rotor winding. The axial length of the stator core is selected with respect to that of the rotor core in such a way that, when the rotor is thermally extended, the end of the rotor core never extends beyond the end of the stator core. With such a constructional arrangement, there is eliminated an excessive temperature rise at the ends of the stator core, and prevented an insulation deterioration of the stator winding and the burning of the stator core.
