A high voltage direct current circuit protection system includes a number n of weakened circuit conductors connected in series with each other and fabricated in a manner that avoids metal fatigue in response to a circulating current load. The system further includes a corresponding number n of cutting elements operable to sever the respective weakened circuit conductors, at least one energy storage element acting on 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 the at least one cutting element to sever the respective weakening circuit conductor, and a corresponding number n of arc chambers arranged in proximity to each respective one of the weakening circuit conductors, where n is an integer greater than 1, and wherein coordination of the circuit protector with the weakened circuit protector is not required.

    一种高电压直流电路保护系统,包括数量为n的弱化电路导体,彼此串联连接并且以避免响应于循环电流负载的金属疲劳的方式制造。该系统还包括可操作为切断相应的弱化电路导体的对应的数量为n的切割元件、作用于切割元件之一的至少一个能量存储元件、引起至少一个能量存储元件中存储能量的释放并引起至少一个切割元件的移位以切断相应的弱化电路导体的控制元件、以及布置在弱化电路导体中的相应的每一个附近的对应的数量为n的电弧室,其中n是大于1的整数,并且其中不需要电路保护器与弱化电路保护器协调。
