Handbook of Electrical and Electronic Circuit-Interrupting and Protective Devices for Deep-Ocean Applications.

摘要

The electrical equipment aboard deep-ocean submersibles has often depended upon fuses for primary circuit protection. The two schemes used for incorporation of outboard fuses in deep-ocean systems involved either a hard shell enclosure (usually filled with air or an inert gas) or an outboard,pressure-compensated,fluid-filled enclosure. In both cases,however,the fuses chosen were usually stock,off-the-shelf items,designed for use in air. Use of hard shell enclosure,while eliminating the need for pressure compensation,is limited by the additional size and weight,the difficulty of heat removal,and the requirement of a large number of penetrators.
