Electric circuit breaker of the gas blast type

Abstract

Abstract 1. A GAS BLAST CIRCUIT BREAKER COMPRISING: A. A FIRST ELECTRODE OF A GENERALLY ANNULAR CONFIGURATION AND A SECOND ELECTRODE SPACED THEREFROM, B. FIRST AND SECOND SPACED-APART NOZZLES PRIMARILY OF METAL ELECTRICALLY CONNECTED TO SAID FIRST AND SECOND ELECTRODES, RESPECTIVELY, C. EACH OF SAID NOZZLES HAVING AN ORIFICE OPENING POSITIONED BETWEEN SAID ELECTRODES, D. MEANS FOR ESTABLISHING BETWEEN SAID ELECTRODES AN ARC THAT HAS ITS OPPOSED TERMINALS ON SAID ELECTRODES AND ITS COLUMN EXTENDING THROUGH SAID ORIFICE OPENINGS, E. MEANS FOR CAUSING TWO STREAMS OF GAS TO FLOW IN GENERALLY OPPOSITE DIRECTIONS FROM THE SPACE BETWEEN SAID NOZZLES THROUGH SAID ORIFICE OPENINGS, ONE STREAM FLOWING PAST SAID FIRST ELECTRODE AND THE OTHER FLOWING PAST SAID SECOND ELECTRODE, F. MAGNETIC MEANS FOR FORCING THE ARC TERMINAL ON SAID FIRST ELECTRODE TO MOVE ALONG SAID FIRST ELECTRODE IN A GENERALLY CIRCULAR PATH SO AS TO DEVELOPA GENERALLY HOLLOW ARC COLUMN IN THE REGION ADJACENT SAID FIRST ELECTRODE, G. AND MEANS FOR DIRECTING ALONG THE LONGITUDINAL AXIS OF SAID HOLLOW ARC COLUMN A JET OF GAS FLOWING FROM THE REGION SAID FIRST ELECTRODE TOWARD SAID SECOND ELECTRODE. D R A W I N G
