摘要 现代舰船中压直流电力系统中,由整流发电机组构成电源,其出口断路器保护要求为发电机侧故障时瞬动和电网侧故障时短延时耐受后再分断。本文阐述了一种基于强迫换流原理的双向混合型直流真空断路器的工作原理,重点对换流过程进行了理论和仿真分析,改进了拓扑结构。通过对换流支路阻抗的双向非对称设计,进行分流比的方向调节,优化了换流参数。研制了额定5k V/6k A断路器样机,等效试验验证了理论分析和参数选择的有效性。 The medium voltage DC power systems of modern ships use rectifier generator as the system source. When faults occur in the generator side, the RGCB(rectifier generator circuit breaker) must act immediately; when faults occur in the grid side, the RGCB has to undergo the fault current for a short period before cut off the short current. A hybrid DC vacuum breaker based on forced commutation principle is expatiated. The topology is improved based on theoretical analysis of commutation process. Asymmetrically bidirectional design and simulation are performed, which indicates the commutation circuit can be optimized upon this way. A 5k V/6k A RGCB was realized. The effectiveness of the theoretical analysis and preference were validated by the results of equivalent tests.
