A study of optimal design method of the low voltage distribution line fuse

摘要

In this paper, we deal with the I-t characteristic of low voltage distribution fuse. It is used to be thermal characteristic in being produced at fuse element part. The elements are divided into low temperature melting element (LTME) and high temperature melting element (HTME). Those parts make of coordination. The characteristics of fuse are decided by material, design and others. We analyze the I-t characteristic curve by using the numerical method. Furthermore, we compare the curve of simulation with that of the experiment.
