Abstract

A switching apparatus includes: a body including: a sidewall that extends from a first end to a second end, the sidewall defining an interior space; and a plurality of electrically insulating sheds that extend radially outward from an exterior surface of the sidewall; a circuit interrupter in the interior space of the body; a first terminal electrically connected to the circuit interrupter; and a second terminal electrically connected to the circuit interrupter. The switching apparatus is configured to be mechanically connected to at least two different types of mounting structures.

First claim

What is claimed is:

1 . A switching apparatus comprising:
a body comprising:
a sidewall that extends from a first end to a second end, the sidewall defining an interior space;
a mounting interface; and
a plurality of electrically insulating sheds that extend radially outward from an exterior surface of the sidewall;
a circuit interrupter in the interior space of the body; a first terminal electrically connected to the circuit interrupter; a second terminal electrically connected to the circuit interrupter; and a mounting system comprising:
a first mounting assembly attached to the first terminal; and
a second mounting assembly attached to the second terminal, wherein
the mounting interface is not attached to the first terminal or the second terminal, and is configured to mechanically connect to a first type of mounting structure, and the first mounting assembly and the second mounting assembly are configured to mechanically connect to a second type of mounting structure that is different from the first type of mounting structure such that the switching apparatus is configured to be mechanically connected to at least two different types of mounting structures, wherein the body further comprises a tank; the at least two different types of mounting structures comprise an electrically insulating bracket and a utility structure, the utility structure is the first type of mounting structure, the electrically insulating bracket is the second type of mounting structure; the mounting interface comprises a mechanical interface configured to connect to a support, the support configured to attach the tank to the utility structure; the tank is grounded; and the mechanical interface is configured to attach to an electrically conductive support.

2 . The switching apparatus of claim 1 , wherein the utility structure comprises one or more of a utility pole and a cross-arm mounted to a utility pole.

3 . The switching apparatus of claim 1 , wherein the mechanical interface comprises a mounting strap that surrounds an exterior of the tank.

4 . The switching apparatus of claim 1 , wherein the mechanical interface comprises a connection point on an exterior surface of the tank, and the connection point is configured to allow the mounting structure to be attached to the tank at the mechanical interface and removed from the tank without damaging the tank, the mechanical interface, or the support.

5 . The switching apparatus of claim 1 , wherein the electrically insulated bracket comprises a visible break mounting bracket or a cutout that lacks a fuse.

6 . The switching apparatus of claim 1 , wherein:
the first mounting assembly is configured to connect the first terminal to a lower portion of the electrically insulating bracket; and the second mounting assembly is configured to connect the second terminal to an upper portion of the electrically insulating bracket.

7 . The switching apparatus of claim 6 , wherein one or more of the first mounting assembly and the second mounting assembly are configured to allow the body to move relative to the electrically insulating bracket.

8 . The switching apparatus of claim 1 , wherein the circuit interrupter comprises a switch capable of repeatedly opening and closing, and the switching apparatus comprises a single-phase recloser.

9 . The switching apparatus of claim 8 , wherein the circuit interrupter comprises a vacuum interrupter.

10 . A system comprising:
an insulating mounting structure comprising: an upper portion, a lower portion, and a middle portion that extends between the upper portion and the lower portion, wherein the upper portion, the lower portion, and the middle portion are a single piece of electrically insulating material; a switching apparatus comprising: a body that extends along a direction from a first end to a second end, a first terminal, a second terminal that extends from the second end along the direction, and a circuit interrupter electrically connected to the first terminal and the second terminal; a first mounting assembly configured to connect the first terminal to the lower portion of the insulating mounting structure; and a second mounting assembly configured to mechanically connect the second terminal to an upper portion of the insulating mounting structure, wherein, the first mounting assembly does not permit the body to rotate about the lower portion of the insulating mounting structure, wherein the system further comprises a damping apparatus configured to damp intentional movement of the body relative to the insulating mounting structure.

11 . The system of claim 10 , wherein the damping apparatus is part of one or more of the first mounting assembly and the second mounting assembly, and the damping apparatus is configured to damp one or more of intentional rotational motion or translational motion of the body.

12 . The system of claim 10 , wherein the damping apparatus comprises a frictional region configured to engage a connection portion coupled to the switching apparatus.

13 . The system of claim 10 , wherein the first mounting assembly prevents the switching apparatus from dropping out of the insulating mounting structure.

14 . A switching apparatus comprising:
a body comprising:
a sidewall that extends from a first end to a second end, the sidewall defining an interior space; and
a plurality of electrically insulating sheds that extend radially outward from an exterior surface of the sidewall;
a grounded tank coupled to the body; a circuit interrupter in the interior space of the body; a first terminal electrically connected to the circuit interrupter; and a second terminal electrically connected to the circuit interrupter, wherein the switching apparatus is configured to be mechanically connected to at least two different types of mounting structures, and wherein the switching apparatus further comprises: a mounting interface configured to attach to the grounded tank, and wherein the at least two different types of mounting structures comprise a utility structure and an insulated bracket, and the mounting interface is configured to attach the switching apparatus to the utility structure; and wherein the mounting interface is made of an electrically conductive material.

15 . A switching apparatus comprising:
a body comprising:
a sidewall that extends from a first end to a second end, the sidewall defining an interior space;
a mounting interface; and
a plurality of electrically insulating sheds that extend radially outward from an exterior surface of the sidewall;
a circuit interrupter in the interior space of the body; a first terminal electrically connected to the circuit interrupter; a second terminal electrically connected to the circuit interrupter; and a mounting system comprising:
a first mounting assembly attached to the first terminal; and
a second mounting assembly attached to the second terminal, wherein
the mounting interface is not attached to the first terminal or the second terminal, and is configured to mechanically connect to a first type of mounting structure, and the first mounting assembly and the second mounting assembly are configured to mechanically connect to a second type of mounting structure that is different from the first type of mounting structure such that the switching apparatus is configured to be mechanically connected to at least two different types of mounting structures, wherein
the body further comprises a tank, the tank comprising an ungrounded tank or a grounded tank;
the at least two different types of mounting structures comp
