Abstract:

The success of inductive storage systems is dependent on the development of fast, low loss opening switches. An approach to this problem is to stage several successively faster switches, such as circuit breakers and fuses, in a manner so as to minimize overall losses while achieving an effective fast opening time. In this paper, we discuss the properties of an aluminum foil fuse immersed in water or hydrogen peroxide for use as one of the final fast acting elements. Although it has been shown that the time to explosion is dependent on the fuse material, peak current amplitude, and risetime, we speculate that the opening characteristics are also influenced by chemical reactions and heat transfer with the surrounding medium. Data is presented showing that the final resistivity can be optimized by proper foil dimensions and further increased by the use of a chemically more active surrounding medium such as hydrogen peroxide.
