SURGE ARRESTER HAVING A VARISTOR ARRANGEMENT AND VARISTOR MODULE FOR USE IN A SURGE ARRESTER

摘要

A surge arrester comprises a varistor arrangement, wherein the varistor arrangement has a plurality of varistor modules (3a, 3b, 3c, 3d, 12a, 12b, 12c, 12d). Between the varistor modules (3a, 3b, 3c, 3d, 12a, 12b, 12c, 12d) electrically conductive connections are provided. The electrically conductive connections are secured by coupling arrangements. Due to the use of the varistor modules (3a, 3b, 3c, 3d, 12a, 12b, 12c, 12d), surge arresters having a variety of electrical characteristics can be implemented.
