| Abstract |
This paper propose analysis and examination of the melting characteristic of fuse elements by repeating overcurrent as a depletion factor of high pressure current limiting fuse through test following existence and nonexistence of extinction material and various configuration of elements. To examine deterioration progress rate by repeating overcurrent we analyzed heat for various element notching configuration, designed plate type, ring type element and estimated the relationship with life span by analyzing breaking characteristic through repeating overcurrent test with adjusting load factor at Silicon Dioxide(SiO2) filled state or in air. A Crack by repeat stress, decrease of section and transformation by friction with extinction material by repeating overcurrent causes a problem which shortens life span based on fuse repeating frequency. Since the contents of this paper might be useful to research the correlation between friction of materials and repeating life span based on load factor of repeating current, the quality of product would be improved through solution of the problem. |
