Abstract

In recent years, due to the spread of various renewable energy power sources and the pursuit of high efficiency and low-power consumption, not only trends in the electric power industry but also the consumption, control methods, and characteristics are diversified. However, in this diversified electric power industry, the fuse (which is the core part responsible for safety) has not developed significantly in classical operation mode, and thus, fires continue to occur. In this paper, the effects of low melting-point metal plating and high melting-point metal plating on operating characteristics and IT curve movement of the fuse are investigated in a cartridge fuse, which is a classic fuse manufacturing method. The effects of plating on the thickness of the fuse are investigated, and various operating characteristics of the fuse are implemented. In addition, it is suggested that the plating of the low melting-point metal moves the rated current line of the fuse to a low rating, and moves operating characteristics to characteristics of delay operation. It is possible to design various operating characteristics using this characteristic.

최근 다양한 신재생 에너지 전력원의 확산과 저전력 고효율화 추구로 인하여 전력산업의 트렌드뿐만 아니라 소모량, 제어 방식과 동작 특성 등도 다변화되고 있다. 하지만 이와 같이 다양화 되고 있는 전력 산업에서 안전을 책임지는 핵심 부품인 퓨즈는 고전적 동작 형태에서 크게 발전하지 못하였고, 이로 인하여 계속해서 화재 및 폭발사고가 발생하고 있다. 이에 본 논문에서는 고전적 퓨즈 제작 방식인 카트리지 퓨즈에서 가용체에 저 융점 금속 도금 및 고 융점 금속 도금이 퓨즈의 동작 특성과 I-T 커브의 이동에 미치는 영향을 확인하고, 퓨즈의 동작 특성을 세분화하는 두께에 따른 도금의 영향을 고찰하여 퓨즈의 다양한 동작 특성을 구현하였다. 이와 함께 저 융점 금속의 도금이 퓨즈의 정격전류 선을 낮은 정격으로 이동시키고 동작 특성을 지연 동작의 특성으로 움직여 이를 활용한 다양한 동작 특성 설계가 가능함을 제시하였다.
