METHOD OF ASSEMBLING ISOLATION TRANSFORMER

摘要

A stator core (11) is mounted to a stationary member (22) and electric wiring on the stator side is carried out, to thereby assemble a first sub-module (20), and a rotor core (12) is mounted to a rotary member (21) and electric wiring on the rotor side is carried out, to thereby assemble a second sub-module (30). Thereafter, the first and second sub-modules are assembled together, with the stator core and the rotor core opposed to each other, whereby a separable transformer is assembled. A guide member (27), having first and second reference faces defining reference positions in diametrical and axial directions of the rotation shaft (21), respectively, is provided in the rotation shaft (21) rotatably supported by the stationary member and mounted with the rotor core. Mounting positions of the cores are determined with use of the guide member, thereby precisely setting a center position between the cores and a gap length g.
