Abstract

A security enclosure for a transformer includes a first sidewall, a second sidewall, and a bottom at least partially enclosing an interior. The bottom has an aperture configured to receive a transformer tank. A front opening provides access to an interior having a first panel. At least one terminal block is connected to the first panel. A door pivots between an open position spaced from the front opening and a closed position covering the front opening.

First claim

What is claimed:

1. A secure enclosure for a transformer comprising:
a bottom, a first sidewall extending from the bottom, and a second sidewall extending from the bottom at least partially enclosing an interior, the bottom having a tank aperture configured to receive a transformer tank;
a front opening providing access to the interior;
a first panel positioned in the interior;
at least one terminal block connected to the first panel;
a door pivotable between an open position spaced from the front opening and a closed position covering the front opening; and
a lock releasably securing the front door in the closed position.

2. The enclosure of claim 1 , wherein the bottom includes a plurality of conductor apertures.

3. The enclosure of claim 1 , wherein a second panel is positioned in the interior and the first panel and the second panel are obliquely angled with respect to one another.

4. The enclosure of claim 1 , wherein the tank aperture is a semi-circular opening.

5. The enclosure of claim 1 , wherein the panel comprises a conductor aperture.

6. The enclosure of claim 1 , wherein the terminal block bridges an opening adjacent to the panel.

7. The enclosure of claim 1 wherein a top cover is slidably connected to the first and second sidewalls and is moveable between a closed and an open position.

8. The enclosure of claim 7 , wherein a lock is positioned on the top cover.

9. The enclosure of claim 7 , wherein the top cover in the closed position prevents movement of the door.

10. The enclosure of claim 1 , further comprising a top wall connected to the first and second sidewalls.

11. The enclosure of claim 10 , wherein at least one hook extends from the top wall.

12. The enclosure of claim 10 , wherein at least one shaft extends from the top wall.

13. A secure enclosure for a transformer comprising:
a bottom having a tank aperture;
a first sidewall extending from the bottom;
a second sidewall extending from the bottom, the bottom, first sidewall, and second sidewall at least partially enclosing an interior;
a front opening providing access to the interior;
a first panel positioned in the interior;
at least one terminal block connected to the first panel;
a top cover slidable between a closed position and an open position to selectively cover the interior; and
a door pivotable between an open position spaced from the front opening and a closed position covering the front opening.

14. The enclosure of claim 13 , wherein the top cover is connected to the first sidewall by a linear slide.

15. The enclosure of claim 13 wherein a cam lock is configured to secure the door in the closed position.

16. A transformer having a secure enclosure comprising:
a transformer having a tank and a low voltage bushing extending from the tank;
an enclosure connected to the transformer at least partially enclosing an interior around the low voltage bushing;
a front opening providing access to the interior;
a first panel positioned in the interior;
a second panel positioned in the interior;
at least one terminal block connected to the first panel and the second panel, and electrically connected to the low voltage bushing;
a door pivotal between an open position and a closed position covering the front opening; and
a lock configured to secure the front door in the closed position.

17. The transformer of claim 16 , wherein a top bar extends from the tank and the enclosure is connected to the top bar.

18. The transformer of claim 16 , wherein the enclosure includes a top cover slidably connected to a first and second sidewall.

19. The transformer of claim 18 , further comprising a top wall connected to the first and second sidewalls, a hook extending from the top wall, and at least on shaft extends from the top wall.
