摘要

This work models the function of medium and low voltage fuses so as to estimate the increase in temperature across the fuse elements during nominal current operation for different types, diameters, element lengths and currents. The power balance in a thin metallic conductor, which simulates the fuse element, was derived and the resulting differential equation solved analytically. The theoretical results were close to the experimental measurements that we made, and the experimental work of other authors.
