Abstract

A rupture resistant system, including a tank configured to increase an inner volume of the tank under increased pressure conditions, wherein the tank includes a component situated within the inner volume of the tank and susceptible to increasing pressure within the tank when under an electrical fault condition, a sidewall extending about the inner volume of the tank, and wherein the sidewall includes an interior surface and an exterior surface, a bottom wall coupled to the sidewall, and a tank cover coupled to the sidewall opposite the bottom wall, wherein the tank cover includes a first plate coupled to a second plate, wherein the second plate extends from the first plate, and the first plate extends over the sidewall and the second plate overlaps and couples to the exterior surface of the sidewall with a first joint.

First claim

The invention claimed is:

1. A rupture resistant system, comprising:
a tank configured to increase an inner volume of the tank under increased pressure conditions, wherein the tank comprises:
a sidewall extending about the inner volume of the tank, the sidewall comprising an interior surface and an exterior surface;
a bottom wall coupled to the sidewall; and
a tank cover coupled to the sidewall opposite the bottom wall, wherein the tank cover comprises a first plate coupled to a second plate, wherein the second plate extends from the first plate, and the first plate extends over the sidewall and the second plate overlaps and couples to the exterior surface of the sidewall with a joint, the first plate and the sidewall being configured to flex outward via the joint to increase the inner volume of the tank; and

a radiator coupled to the tank, the radiator comprising a first panel and a second panel defining an inner volume of the radiator, the first panel and second panel being configured flex outward to increase the inner volume of the radiator,
wherein flexing of the sidewall, the first plate, the first panel, and the second panel together increases the inner volume of the tank and the inner volume of the radiator under pressure conditions that exceed a predefined limit.

2. The system of claim 1 , wherein the first joint comprises a portion of the second plate directly welded to the sidewall.

3. The system of claim 1 , comprising a flange coupled to the external surface of the sidewall, wherein the first joint comprises a weld between the second plate and the flange.

4. The system of claim 1 , wherein the first plate does not contact the sidewall.

5. The system of claim 1 , wherein the first plate and second plate are one-piece.

6. The system of claim 1 , wherein the first plate and second plate connect to each other with a curved portion.

7. The system of claim 1 , further comprising a component situated within the inner volume of the tank wherein the component comprises a transformer.

8. A transformer system, comprising:
a transformer tank configured to house a transformer, wherein the transformer tank comprises:
a sidewall extending about an inner volume of the transformer tank, wherein the sidewall is configured to surround the transformer, and the sidewall comprises an interior surface and an exterior surface;
a bottom wall coupled to the sidewall;
a tank cover coupled to the sidewall opposite the bottom wall, wherein the tank cover comprises a first plate and a second plate extending from the first plate, the first plate extends over the sidewall, and the second plate overlaps and couples to the exterior surface of the sidewall with a joint, the first plate and the sidewall being configured to flex outward via the joint to increase the inner volume of the tank; and

a radiator coupled to the transformer tank, the radiator comprising a first panel and a second panel defining an inner volume of the radiator, the first panel and second panel being configured flex outward to increase the inner volume of the radiator,
wherein flexing of the sidewall, the first plate, the first panel, and the second panel together increases the inner volume of the transformer tank and the inner volume of the radiator under pressure conditions that exceed a predefined limit.

9. The system of claim 8 , comprising a header pipe connecting the radiator and the transformer tank.

10. The transformer system of claim 9 , wherein the header pipe comprises a flow restrictor to control flow from the transformer tank to the radiator under normal operating conditions.

11. The transformer system of claim 8 , wherein the first panel is coupled to the header pipe.

12. The transformer system of claim 11 , wherein a spacer is attached to the first panel and the second panel.

13. The transformer system of claim 8 , wherein the joint comprises a portion of the second plate that is directly welded to the exterior surface of the sidewall.

14. The transformer system of claim 8 , comprising a flange coupled to the exterior surface of the sidewall, wherein the joint comprises a weld that couples the second plate to the flange.
