Improved High Power Circuit Interrupter

提出了一种新型固态断路器的研究方案。该装置可作为大型（400kv, 1ka）工业或公用事业电路的断路器。所提出的装置有潜力通过同时增加电流变化率di/dt和由此产生的系统电压变化率dV/dt来显着扩展现有断路器的性能。拟议的研究包括对按比例缩小的断路器装置进行分析计算和实验测试。研究者将独立测试小型装置的di/dt和dV/dt性能。快速作用，大功率交流断路器在一般电力应用中有应用，并将提供一个改进的性能水平，目前还没有达到这一点。

Research is proposed on a novel solid state electric circuit breaker. The device can be used as a large-scale (400 kV, 1 kA) industrial or utility circuit interrupter. The proposed device has the potential to significantly extend the performance of existing circuit breakers by simultaneously increasing the rate of change of current, di/dt, and the resulting rate change in system voltage, dV/dt. The proposed research involves analytical calculations and experimental tests of a scaled-down circuit breaker device. The investigator will independently test the di/dt and dV/dt performance of a small scale device. Fast acting, high power AC circuit breakers have application in general electric-power applications and would provide an improved performance level that has not been attained to this point.
