Abstract

A surge arrester, in particular for arresting surges, includes a housing and a disconnecting device. The housing is divided into at least two housing parts, and the disconnecting device connects the housing parts to one another.

First claim

The invention claimed is:

1. A surge arrester to be connected to an active conductor along a connection path, the surge arrester comprising:
a housing being subdivided into at least two housing parts; and
a disconnecting device connecting said at least two housing parts to one another, said disconnecting device, in an event of a fault, interrupting the active conductor or connection path by disconnecting said at least two housing parts.

2. The surge arrester according to claim 1 , wherein said disconnecting device connects said at least two housing parts to one another centrally.

3. The surge arrester according to claim 1 , wherein said at least two housing parts are disposed at a predefined angle of less than 180° with respect to one another when said disconnecting device is closed.

4. The surge arrester according to claim 1 , wherein said at least two housing parts have end sides, and said disconnecting device is mounted rotatably at a respective one of said end sides of each of said at least two housing parts.

5. The surge arrester according to claim 1 , wherein said at least two housing parts are two housing parts, and said disconnecting device mechanically and electrically interconnects said two housing parts.

6. The surge arrester according to claim 1 , wherein said at least two housing parts have end sides, and joints each rotatably mount a respective one of said at least two housing parts at a respective one of said end sides.

7. The surge arrester according to claim 6 , wherein said joints suspend said at least two housing parts.

8. The surge arrester according to claim 6 , wherein said at least two housing parts have longitudinal axes, and said joints each have a respective pivoting axis running transversally to said longitudinal axes of said at least two housing parts.

9. The surge arrester according to claim 6 , wherein each respective one of said joints is a ball-and-socket joint, a universal joint or a rotary joint.

10. The surge arrester according to claim 1 , wherein said at least two housing parts have outer rotationally mounted ends, and one of said outer rotationally mounted ends of one of said at least two housing parts is suspended on a ground side.

11. The surge arrester according to claim 1 , wherein said at least two housing parts have outer rotationally mounted ends, and one of said outer rotationally mounted ends of one of said at least two housing parts is suspended on a voltage side.

12. The surge arrester according to claim 11 , wherein the voltage side is a high voltage side.
