Abstract

An arrester assembly is disclosed. The assembly includes a surge arrester, a disconnector attached to the surge arrester, and a mounting bracket disposed intermediate the surge arrester and the disconnector. The mounting bracket has a first end and a second end, the first end arranged and disposed for attaching the mounting bracket to a support. The mounting bracket further includes a collar extending away from the second end of the surge arrester to surround the disconnector and to provide a mechanical interface to resist rotational movement of the disconnector with respect to the mounting bracket.

Claims

1. An arrester assembly comprising:

a surge arrester;

a disconnector attached to the surge arrester; and

a mounting bracket disposed intermediate the surge arrester and the disconnector, the mounting bracket having a first end and a second end, the first end arranged and disposed for attaching the mounting bracket to a support, the mounting bracket further having a collar extending away from the second end of the surge arrester to surround the disconnector and to provide a mechanical interface to resist rotational movement of the disconnector with respect to the mounting bracket.

2. The arrester assembly of claim 1, wherein the disconnector comprises an upper fitting attached to the surge arrester, a lower fitting having a ground stud extending away from the lower fitting, and a housing connecting the upper fitting to the lower fitting.

3. The arrester assembly of claim 2, wherein the lower fitting has a head having between four to eight planar faces.

4. The arrester assembly of claim 3, wherein the collar has inner collar walls formed to a shape and size complementary to the lower fitting head.

5. The arrester assembly of claim 1, wherein the mounting bracket collar has an inner passage having a first width defined by a first set of inner collar walls and a second width defined by a second set of inner collar walls that is wider than the first width.

6. The arrester assembly of claim 5, wherein the second set of inner collar walls are configured in a hexagonal shape.

7. The arrester assembly of claim 1, wherein the collar surrounds the disconnector without restraining axial travel of the disconnector.

8. The arrester assembly of claim 7, wherein the collar is configured complementary to the disconnector.

9. The arrester assembly of claim 1, wherein the mounting bracket forms an arrester assembly tool for attaching the disconnector to the surge arrester.

10. The arrester assembly of claim 1, wherein the mounting bracket is constructed of a glass filled polyester material.

11. The arrester assembly of claim 1, wherein the disconnector comprises a metallic component and a phenolic component.

12. An arrester assembly comprising

a surge arrester;

a disconnector comprising an upper fitting, a lower fitting having a ground stud extending away from the lower fitting, and a housing connecting the upper fitting to the lower fitting, the disconnector being attached to the surge arrester via the upper fitting; and

a mounting bracket disposed intermediate the surge arrester and the disconnector, the mounting bracket having a first end and a second end, the first end arranged and disposed for attaching the mounting bracket to a support, the mounting bracket furthering having a collar at the second end extending away from the surge arrester and surrounding the disconnector,

wherein the lower disconnector fitting includes a head having between four to eight planar faces,

wherein the mounting bracket collar has an inner passage having a first width defined by a first set of inner collar walls and a second width defined by a second set of inner collar walls, wherein the second set of inner collar walls are configured complementary to the lower fitting head, and

wherein the collar provides a mechanical interface to resist rotational movement of the disconnector with respect to the mounting bracket but does not restrain axial travel of the disconnector.

13. The arrester assembly of claim 12, wherein the disconnector housing is constructed of a phenolic material.

14. The arrester assembly of claim 12, wherein the mounting bracket is constructed of a glass-filler polyester.

15. The arrester assembly of claim 12, wherein the disconnector housing can resist up to about 20 foot pounds of torque without cracking.
