|1. (WO2017154361) STATIONARY INDUCTION ELECTRICAL APPARATUS|
|Title:||STATIONARY INDUCTION ELECTRICAL APPARATUS|
The objective of the invention is to suppress, in a stationary induction electrical apparatus equipped with an iron core having a rectangular cross-section, the deformation of a coil during a short circuit. In order to achieve this objective, a transformer serving as the stationary induction electrical apparatus according to the present invention comprises: an iron core 1 having a rectangular cross section; and an inner coil 3 and an outer coil 4, whereof the circling shape assumes an angular form or a race track form. Disposed between the inner coil 3 and the outer coil 4 is an inter-internal-external-coil supporting member 5 for supporting the outer periphery 34 of the inner coil 3 and the inner periphery 44 of the outer coil 4. The inter-internal-external-coil supporting member 5 has a corner supporting member 6 abutting corner portions 32, 42.
