Abstract
Abstract - General fuse elements of solution for fast acting operation characteristics made using silver or silver alloy, those are not able to dominate cost competition to the advanced global leaders that have not only high technology but competitive price. In this study, the method that compose the fuse elements manufactured solution of fast acting operation characteristics by using precision multi-layer thin film plating and helical cutting process from low-priced copper metal. Furthermore, in order to move rated current line of fuse due to the heat loses, the manufacture construction method of fixed resistor is introduced, and then Ni-P plating layer and Sn plating layer are introduced multiply for controling fine opening time characteristics. So this study can establish the high productive and low-priced production method.Key Words : Fuse, Fast acting type, Multi-layer plating, Fixed resistor, Helical cutting, Fuse elements†Corresponding Author : Dept. of Metallurgical Engineering,Pukyong National University, Korea E-mail : metlccy@pknu.ac.kr* Dept. of Metallurgical Engineering, Pukyong National University, Korea Received : October 16, 2015; Accepted : February 19, 2016
