        고압 대전류 아크의 복사강도 측정

        宋基東(Ki-Dong Song),吳年浩(Yeon-Ho Oh),鄭鎭敎(Jin-Kyo Chong),趙龍成(Yong-Sung Cho) 대한전기학회 2006 전기학회논문지 B Vol.55 No.11

        This paper presents the measured radiation intensity of high-pressure and large-current arc with the current. In order to measure the radiation intensity of large-current arc, a model circuit breaker was specially designed and manufactured and the method using an astronomical telescope was utilized after various measuring methods were investigated, A trigger system was designed and fabricated to coincide the time of desired current with the exposure time of 1㎳ of the spectroscope. A high-speed camera was used to investigate the shape and behavior of the arc and the captured results have been used to calculate the radiation energy. The calculated arc temperature with Boltzmann plot method using the measured radiation intensity have 18, 000 ~ 27, 000 K to the current 4㎄ ~ l5㎄ And also, using the calculated arc temperature and the captured arc shape the radiation energy of the current 5㎄ ~ 15㎄ were calculated with 8×10? ~ 4.0×10? W/m respectively.
