<p>PROBLEM TO BE SOLVED: To solve a problem of a conventional transformer, in that when an earthquake occurs, swing of, especially, an iron core is significant, causing fall of a main member such as a coil stand, and also to solve another problem in that, although swing of an iron core can be hindered by connecting the upper end of the iron core and an installation surface by means of a frame or the like, providing such a frame increases a material cost and man days for work.SOLUTION: A mold transformer 1 is composed of an iron core 2 and a coil 3. The upper part and lower part of the iron core are provided with an upper core fastener and a lower core fastener respectively. The upper core fastener and the lower core fastener are connected by a connecting member, which is a combination of a rigid body and an elastic body.By using simple means having such a configuration, swing of iron core can be restricted, thus making it possible to prevent fall of a main member.</p> |
