Abstract

A high voltage, direct current circuit protection system includes a number n of weakened circuit conductors connected in series to one another and being fabricated in a manner to avoid metal fatigue in response to cyclic current loads. The system also includes a corresponding number n of cutting elements operable to sever the respective weakened circuit conductors, at least one energy storage element acting upon one of the cutting elements, a control element causing a release of stored energy in the at least one energy storage element and causing a displacement of at least one of the cutting elements to sever the respective weakened circuit conductor, and a corresponding number n of arc chambers arranged proximate each respective one of the weakened circuit conductors, wherein n is an integer greater than 1 and wherein no circuit protector coordination with the weakened circuit protectors is required.
