Abstract:
1. A method of measuring a three-dimensional shape of a connection assembly of a stator coil in a turbine generator, the turbine generator including: the stator coil contained in a slot provided in a stator core and penetrating the stator core in an axial direction; a terminal box provided in correspondence with a coil end portion of the stator coil; a header casing pipe connected to the coil end; a mounting plate configured to mount an end shield; and an end plate configured to mount a bearing bracket, the header casing pipe, the mounting plate, and the end plate being mounted on an outer peripheral plate of a stator frame forming the terminal box, the method comprising: first measuring a three-dimensional shape of a measurement area of the connection assembly of the stator coil in a measurement range set in advance by a laser non-contact three-dimensional shape measurement device; second measuring a three-dimensional shape of a measurement area of the connection assembly of the stator coil in a measurement range set in advance by a multi-joint contact three-dimensional shape measurement device, the multi-joint contact three-dimensional shape measurement device including a plurality of arms being coupled via a joint including a built-in encoder; and integrally synthesizing the three-dimensional shape data measured in the first measurement, the three-dimensional shape data measured in the second measurement, and shape measurement data of a local area measured manually, thereby drafting a plan of the stator connection assembly.
