PURPOSE:To obtain an electric apparatus with a magnetic shielding plate which is easy to manufacture and holds an attracting effect of leakage flux by a method wherein the 1st magnetic shielding plate unit is provided so as to be astride on the core legs of three phases and the 2nd magnetic shielding plate unit which is devided at the core legs of three phases is provided so as to be arranged with a gap between the sub-units. CONSTITUTION:A magnetic shielding plate 9 is composed at least of two kinds of magnetic shielding plate units 10, 11 and the 1st magnetic shielding plate unit 10 is so provided as to be astride over the core legs 1a, 1b, 1c of three phases and the 2nd magnetic shielding unit 11 is devided at the center leg 1b of the core legs 1a, 1b, 1c into two magnetic shielding plate sub-units 11a, 11b which are provided with a gap (g). The magnetic shielding plate 9 is provided in parallel to a core leg base 1 and at the same time the 1st magnetic shielding plate unit 10 is divided at the phase centers of the core legs 1a, 1c of left and right sides to make the magnetic shielding plate unit 10a and the 3rd magnetic shielding plates 10b, 10c are provided outside the magnetic shielding plate unit 10a with a gap g. In other words, the 1st magnetic shielding plate 10 is composed of magnetic shielding plate units 10a, 10b, 10c. |
