    • In accordance with the invention, a fuse comprises a reactive composite structure to interrupt the flow of current in a circuit. The term fuse, as used herein, is intended to cover current interrupters generically and thus encompasses fuses, circuit breakers and other devices for interrupting the flow of current through a conductor. Reactive composite structures comprise two or more phases of materials spaced in a controlled fashion throughout a composite in uniform layers, local layers, islands, or particles. Upon appropriate excitation, the materials undergo an exothermic chemical reaction that spreads rapidly through the composite structure generating heat and light. Moreover a reactive composite structure can break apart upon reaction. This breakage can rapidly interrupt the flow of current through the reactive composite structure. Such structures can provide high-speed current interruption. In addition, reactive composite structures can have abrupt reaction initiation thresholds such that a pulse of energy of a certain magnitude may initiate a clearing reaction but a slightly smaller pulse of energy may not. Such a reactive composite structure can thus provide a high speed, highly sensitive current interrupter.
    • 根据本发明,保险丝包括用于中断电路中的电流的电抗复合结构。 本文所用的术语“熔断器”旨在一般地覆盖电流断流器,因此包括熔断器,断路器和用于中断通过导体的电流流动的其它装置。 反应性复合结构包括以均匀层,局部层,岛或颗粒在整个复合材料中以受控的方式间隔的两种或多种材料相。 在适当的激发下,材料经受放热的化学反应,其迅速扩散通过产生热和光的复合结构。 此外,反应性复合结构可以在反应时分裂。 这种断裂可以快速地中断通过反应性复合结构的电流的流动。 这种结构可以提供高速电流中断。 此外,反应性复合结构可以具有突然的反应起始阈值,使得一定量级的能量脉冲可能引发清除反应,但是稍微较小的能量脉冲可能不起作用。 因此,这种反应性复合结构可以提供高速,高灵敏度的电流中断器。
