이 논문은 단락 조건에서 스위칭 전류에 대한 전력 엔지니어링을 위한 저전압 스위칭 장치 접점의 열 침식 프로세스에 대한 지식 상태를 제시합니다. 단락 아크의 그래픽 모델과 접점에 도입된 아크 전력의 분포가 표시됩니다. 방전시 접촉온도를 측정하는 방법이 정교화되었다. 얻은 테스트 결과가 표시됩니다. 즉, 전류, 에너지 및 적분 ∫과 같은 아크 매개변수의 함수로 접촉 온도의 변화가 표시됩니다.idt. 테스트 결과, 고전류 범위에서 온도 상승과 아크 매개변수 사이의 관계를 표현하는 곡선에 "중단점"이 존재하는 것으로 나타났습니다. 이 지점의 위치는 접점의 직경과 전류 값에 따라 달라지며 전극에 전달되는 열 에너지와 관련됩니다. 접점의 각 직경에 대해 아크의 에너지량 값(전류, ∫)이 존재하는 것으로 관찰되었습니다.idt, 에너지), 아크 루트의 직경은 접촉 직경과 동일합니다. 이 값을 초과하면 곡선 모양이 변경됩니다. 얻은 결과는 다른 연구자들이 이전에 관찰했던 전류의 함수로서 접촉 아크 침식을 나타내는 곡선의 불연속성을 설명하고 확인합니다.

Abstract: The paper presents the state of knowledge about thermal-erosion processes in contacts of low-voltage switching devices for power engineering on switching currents under short-circuit conditions. The graphical models of the short arc and the distribution of arc power introduced into contacts are shown. The method for measurements of a contact temperature during an electric discharge has been elaborated. The obtained test results are presented, i.e. changes of a contact temperature as a function of arc parameters such as current, energy, and integral ∫idt. The tests have shown that a "break point" exists on the curve expressing the relationship between a temperature rise and arc parameters in the range of high currents. The location of this point is dependent on a diameter of contacts and a value of current, and is associated with thermal energy delivered to electrodes. It has been observed that for each diameter of contacts there exists such value of an energetic quantity of arc (current, ∫idt, energy), at which diameters of arc roots are the same as a contact diameter. Above this value, the shape of a curve is changed. The obtained results explain and confirm the discontinuity of a curve expressing a contact arc erosion as a function of current, which was observed earlier by the other research workers.
