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.

Abstract: There is provided a property recovering method which can be applied to a high-temperature member whose properties such as strength and ductility have been deteriorated by the long-term use at a high temperature to recover its properties to those before the use, enable its reuse, and contribute to the effective use of resources and the conservation of environment. A Ni-base heat resistant alloy having a particular composition, whose properties have been deteriorated by heat history, is subjected to first-stage solution treatment, in which the alloy is held at a temperature of 1175 to 1225° C. for 1 to 5 hours and then furnace-cooled, then subjected to second-stage solution treatment, in which the alloy is held at a temperature of 1115 to 1165° C. for 1 to 5 hours and then air-cooled, and further subjected to aging treatment, in which the alloy is held at a temperature of 810 to 860° C. for 22 to 26 hours.
