Abstract

An overvoltage arrester includes a column extending between first and second electrical terminals and having resistance elements being stacked on one another and having first and second opposite contact faces. The first and second contact faces of adjacent resistance elements adjoin one another. The column has a first group of resistance elements being directly connected by their first contact faces to the first electrical terminal and by their second contact faces to the second electrical terminal, and a second group of resistance elements being directly connected by their first contact faces to the second electrical terminal and by the second contact faces to the first electrical terminal. The result is a compact overvoltage arrester in which all of the resistance elements are connected electrically parallel with one another and which has a particularly high energy absorption capacity.

Dependent claims

An overvoltage arrester, comprising:

first and second electrical terminals;
a column extending between said first and second electrical terminals, said column being composed of resistance elements each having first and second mutually opposite contact faces;
said resistance elements being stacked on top of one other with said first contact face of one resistance element adjoining said second contact face of an adjacent resistance element in said column;
said resistance elements of said column being disposed in first and second groups;
said first contact face of said resistance elements of said first group being directly connected to said first electrical terminal and said second contact face of said resistance elements of said first group being directly connected to said second electrical terminal;
and
said first contact face of said resistance elements of said second group being directly connected to said second electrical terminal and said second contact face of said resistance elements of said second group being directly connected to said first electrical terminal.
