Abstract
A surge arrester includes a gas-filled closed arrester body that is formed by a first annular ceramic body and two electrodes at a distance from one another. A second annular ceramic body is arranged in the interior of the arrester body and is at a distance from the first ceramic body and has a physical height that is less than the physical height of the first ceramic body.
Claims19
A surge arrester comprising:
- a gas-filled closed arrester body, which is formed by a first annular ceramic body and two electrodes that are spaced from one another;
- and
- a second annular ceramic body arranged within an interior of the gas-filled closed arrester body, the second annular ceramic body having a radial distance from the first annular ceramic body.
A surge arrester comprising:
- a gas-filled closed arrester body, which is formed by a first annular ceramic body and two electrodes that are spaced from one another, wherein the electrodes comprise pin electrodes;
- and
- a second annular ceramic body arranged in an interior of the arrester body at a distance from the first ceramic body, the second annular ceramic body having a physical height which is less than a physical height of the first ceramic body.
An arrangement of a plurality of surge arresters to form an array, the arrangement comprising:
- at least two surge arresters, each surge arrester comprising a gas-filled closed arrester body that is formed by a first annular ceramic body and two electrodes that are spaced from one another;
- and a second annular ceramic body arranged in an interior of the arrester body at a distance from the first ceramic body, the second annular ceramic body having a physical height which is less than a physical height of the first ceramic body;
- wherein two directly adjacent surge arresters have a common electrode;
- and
- wherein the common electrode comprises a pin electrode which is used on both sides.
