ABSTRACT:
A unique design and method of construction is presented for a tank-like structure which houses an electrical component immersed within a dielectric fluid. The tank is formed by a generally cup-shaped enclosure and a cover. In one embodiment the cover carries a means for electrically connecting the interior of the tank with its exterior. The cover and the enclosure are joined by an overlapping edge means. By overlapping the marginal portions of the cover and the enclosure, such that the leading edges are disposed in the opposite direction, a joint is formed which is less likely to rupture than one formed by overlapping the marginal portions with the leading edges disposed in the same direction. The overlapping edge means, allows the designer to pre-select that portion of the interface between the cover and the enclosure where, in the event of an overpressure condition within the tank, a rupture should preferably occur, thereby minimizing the damage which could result from the discharge of pressurized gas and liquid. The tank design also includes provision for a retention means to hold the solid portions of the electrical apparatus housed by the tank within the tank in the event that the tank ruptures and fluid is lost. Several specific embodiments are illustrated and described in detail, with specific reference to a tank which houses a plurality of capacitor packs.
