Abstract
A high-voltage surge arrester includes an electrically conductive first terminal and an electrically conductive second terminal longitudinally spaced from the first terminal. A plurality of metal oxide varistor (MOV) bars are included, each of which extends from the first terminal to the second terminal and electrically contacts the first terminal and the second terminal. A heat conducting material contacts the MOV bars.

A high-voltage surge arrester, comprising:
- an electrically conductive first terminal;
- an electrically conductive second terminal longitudinally spaced from the first terminal;
- a plurality of metal oxide varistor (MOV) bars, each of which extends from the first terminal to the second terminal and electrically contacts the first terminal and the second terminal;
- and
- a heat conducting material contacting a periphery of the MOV bars.

A high-voltage surge arrester, comprising:
- an electrically conductive first terminal;
- an electrically conductive second terminal longitudinally spaced from the first terminal;
- and
- a plurality of MOV assemblies stacked sequentially between the first terminal and the second terminal, wherein at least one of the MOV assemblies includes a plurality of metal oxide varistor (MOV) bars and a heat conducting material extending between each of the plurality of MOV bars and others of the MOV bars to separate the MOV bars from each other.
1 more element
A method of manufacturing a high-voltage surge arrester, comprising:
- selecting a desired length for each of a plurality of metal oxide varistor (MOV) bars based on a desired operating voltage of the surge arrester;
- selecting a desired number of MOV bars to include in the plurality of metal oxide varistors based on a desired current rating of the surge arrester;
- forming the desired number of MOV bars having the desired length to provide the plurality of metal oxide varistor (MOV) bars;
- arranging the plurality of MOV bars so that each of the MOV bars extends lengthwise from an electrically conductive first terminal of the surge arrester to an electrically conductive second terminal of the surge arrester and electrically contacts the first terminal and the second terminal;
- placing a heat conducting material contacting the arranged MOV bars;
- and
- securing the arranged plurality of MOV bars to provide the surge arrester having the desired operating voltage and the desired current rating.
