STATIONARY INDUCTION ELECTRIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a stationary induction electric apparatus where a butting clearance gap dimension of a junction part of an iron core is managed without impairing workability.

SOLUTION: The stationary induction electric apparatus is provided with: a rectangular iron core composed by jointing two sets of U-shaped iron core members each formed of a stacked magnetic steel sheet to each other by an iron core leg part; a coil inserted into the iron core leg part; and a fitting supporting the iron core. The stationary induction electric apparatus is characterized by being provided with a restriction part forcibly restricting a butting clearance gap dimension or a superposition margin dimension of a junction part of the two sets of U-shaped iron core members. The restriction part may be an outer height restriction member provided for the fitting to restrict the outer height of the iron core, or an inner height restriction member inserted in an end surface of the coil and the inner surface of a window of the iron core to restrict the inner height in the window of the iron core.
