Abstract |
According to a miniaturization and integration of electric device, a little size of fuse satisfying the current carrying capacity as well as an explosive tolerance and current interrupt rating are required. Fe-Ni alloy is applied to decrease an oxidation of fuse elements. A resistance and T.C.R(temperature coefficient of resistance) of a fuse are analyzed by changing a content of Ni And full rated current I-T curve from 1A to 6.3A has been tested. In order to an explosive energy, a straight wire type is selected to reduce a fuse melting time. An interrupt rating test was conducted by changing a content of Ni and the optimal content of Ni is to be 40% |
