  • Publication number: 20200294700
    Abstract: A transformer includes a transformer body, a tank, a conservator, a plurality of support fittings, and at least one mounting seat. Transformer body includes an iron core and a winding. Tank includes an upper tank, a middle tank, and a lower tank that are bonded together to form an internal space accommodating transformer body. Conservator is arranged at a position above tank. The plurality of support fittings are arranged side by side at intervals to support conservator. At least one mounting seat is bonded to both a peripheral wall of upper tank and a peripheral wall of middle tank, and fixed to tank, and the plurality of support fittings are attached.

  • Publication number: 20190206610
    Abstract: A lead wire support device is made of an insulator, and supports a lead wire drawn out from a winding of a stationary induction apparatus. The lead wire support device is fixed to an inner wall of a tank. A creepage path from the lead wire to the inner wall includes a first point and a second point. The first point is a point at which a creepage distance from the lead wire is a first distance. The second point is a point at which the creepage distance from the lead wire is a second distance longer than the first distance. A potential at the second point is higher than a potential at the first point.
