PURPOSE:To dispense with a working on magnetic shield by a method wherein a lead wire is penetrated from the position such as the interphase and the like other than the opposing part of a coil where installation of the magnetic shield is unnecessary. CONSTITUTION:A plurality of tabular magnetic shields 7 are provided on the inner surface of the tank 4 opposing to a coil 2, and a lead wire 3 is penetrated from the interphase part in the tank 4 having no magnetic shield 7 on the interphase which is not opposing to the coil 2. Accordingly, the possibility of generation of a local overheating on a pocket 8 can be eliminated without bending the path of leakage flux. Also, working manhours can be cut down, because the work to be performed on the magnetic shield is unnecessitated. |
