Abstract

COMUTADOR GIRATÓRIO E MÉTODO DE UTILIZAR UM COMUTADOR GIRATÓRIO. A presente invenção refere-se a comutadores giratórios, e em particular a comutadores giratórios de ruptura dupla de polo duplo (ou multipolo) para interrupção de corrente. O comutador giratório compreende primeiro e segundo polos (2, 4) cada polo incluindo um elemento de união giratório (24) e um par de barras de distribuição fixas (6a, 6b; 8a, 8b) tendo pelo menos um contato primário (14), em que o comutador giratório é adaptado de tal modo que a direção de fluxo de corrente através do primeiro polo (2) seja oposta à direção de fluxo de corrente através do segundo polo (4) de tal modo que arcos estabelecidos no primeiro polo (2) sejam defletidos para longe dos arcos estabelecidos no segundo polo (4).SWIVEL SWITCH AND METHOD OF USING A SWITCH SWITCH. The present invention relates to rotary switches, and in particular to dual-pole (or multipole) double-break rotary switches for current interruption. The rotary switch comprises first and second poles (2, 4) each pole including a rotatable connector (24) and a pair of fixed distribution bars (6a, 6b; 8a, 8b) having at least one primary contact (14) , wherein the rotary switch is adapted such that the direction of current flow through the first pole (2) is opposite to the direction of current flow through the second pole (4) such that arcs established in the first pole ( 2) are deflected away from the arcs established at the second pole (4).
