- W2047810871 abstract "본 논문은 변압기 1차측에 설치된 전력퓨즈의 열화현상을 진단하고 문제점을 해결하고자 한다. 전력퓨즈의 열화현상은 퓨즈 엘리멘트에 반복하여 흐르는 평상전류에 의해 오동작하는 주된 원인이 된다. 따라서 전력퓨즈 전, 후단과 옥내 변전실내 전력기기의 온도변화와 전력퓨즈 열화현상의 관계를 규명하여, 열화현상의 원인을 제거하여 부하설비의 증설을 조사하여 전력퓨즈를 재산정하였다. 변압기는 개선전과 비교하여 평균 <TEX>$6[^{circ}C]$</TEX>가량 하락하였고, 전선로의 온도는 <TEX>$7{sim}8[^{circ}C]$</TEX>가량 개선되었다. 전력용 콘덴서와 직렬리액터는 실내온도 및 기기동조화와 관계되어 <TEX>$2{sim}3[^{circ}C]$</TEX> 높은 상태 유지됨을 알수 있었다. 연구대상인 전력퓨즈 3상간 온도차는 <TEX>$0.5{sim}1.0[^{circ}C]$</TEX>로 안정화 됨을 보였다. 이에 따라 옥내 변전실내의 환경적인 전력기기간의 온도발생요인을 제거하여 전력퓨즈의 열화 및 온도상승을 억제할 수 있음을 제안 하였다. This paper aims to solve the problem deterioration of power fuses. The deterioration of a power fuse is a cause of failure misoperation by a normal current flowing reduplicatively to fuse the element. An extension survey of a load feature rerating power fuse examined the power fuse deterioration removal, the cause of the deterioration of the power fuse, the front-after, and the thermal variation of the inside transformer room electric power equipment. The transformer showed an average improvement of <TEX>$6[^{circ}C]$</TEX>. The temperature of the electrical line showed <TEX>$7{sim}8[^{circ}C]$</TEX> improvement. The static condenser and direct reactor was <TEX>$2{sim}3[^{circ}C]$</TEX> high-state maintenance the temperature and equipment syntonization relationship. In the subject of study <TEX>$0.5{sim}1.0[^{circ}C]$</TEX> stabilizing three phase power fuse temperature differential was. Suggestion in the transformer room environment power equipment between the cause temperature happen elimination to deterioration of power fuse and temperature rise control." @default.
