은 전기 접점은 200V-500VDC/10A 저항 회로에서 일정한 개방 속도로 분리되었습니다. 영구자석의 횡자기장에 의한 자기분출에 의해 브레이크 아크가 소멸되었습니다. 영구 자석은 브레이크 아크의 길어진 모양을 단순화하기 위해 적절하게 위치되었습니다. 횡자기장의 자속밀도는 20에서 140mT까지 다양하였다. 두 대의 고속 카메라를 동시에 사용하여 파손 호의 이미지를 수평 및 수직 방향에서 관찰했습니다. 관찰된 이미지로부터 소멸 직전의 호 길이를 분석하였다. 자석의 적절한 배치에 의한 브레이크 아크의 형상이 단순화됨에 따라 모든 실험 조건에서 브레이크 아크의 경로의 대부분을 추적할 수 있을 정도로 브레이크 아크의 형상이 단순함을 알 수 있었다. 아크 길이는 공급 전압이 증가함에 따라 증가하고 자속 밀도가 증가함에 따라 감소했습니다. 이러한 결과는 아크 연장 시간과 아크 연장 속도의 관점에서 논의될 것이다.

Abstract: Silver electrical contacts were separated at constant opening speed in a 200V-500VDC/10A resistive circuit. Break arcs were extinguished by magnetic blowing-out with transverse magnetic field of a permanent magnet. The permanent magnet was appropriately located to simplify the lengthened shape of the break arcs. Magnetic flux density of the transverse magnetic field was varied from 20 to 140mT. Images of the break arcs were observed from the horizontal and vertical directions using two high speed cameras simultaneously. Arc length just before extinction was analyzed from the observed images. It was shown that shapes of the break arcs were simple enough to trace the most part of paths of the break arcs for all experimental conditions owing to simplification of the shapes of the break arcs by appropriate arrangement of the magnet. The arc length increased with increasing supply voltage and decreased with increasing magnetic flux density. These results will be discussed in the view points of arc lengthening time and arc lengthening velocity.
