| titleOfInvention | Laminated magnetic core for stationary induction electric apparatus |
| abstract | PURPOSE:To improve magnetic characteristics of iron loss, exciting current, noise and the like and reduce the working man-hour and cost by combining at least 2 types of groups of steel plates with a specific method. CONSTITUTION:Core legs 1 and yokes 2 of a single-phase two-leg core type transformer are overlapped and jointed at overlapping parts 3. Groups 1a, 1b, 1c and 2a, 2b, 2c of steel plates whose edges are trued up are butted from leg side and yoke side and the steel plates are laminated with a repetition of two of 1b, three of 1c, one of 1a, one of 1a, three of 1c and so on to the direction of lamination. When such core is used, a space factor of the steel plates against a whole cross sectional area of the core is 70% on A-A cross section of the figure and also 70% on B-B cross section. Therefore, concentration of flux at the core jointing part is relieved as compared with the conventional core so that iron loss, exciting current and noise can be suppressed. |
