摘要
通过对6 kV厂用系统直流回路短路电流的计算,结合直流断路器的级差配合试验,分析直流断路器的选择性配合电流比,从而为存在同类问题的电厂提供借鉴。
Based on the calculation of short-circuit current of DC circuit in 6 kV auxiliary system,combined with the differential coordination test of DC circuit breaker,this paper analyzes the selective coordination current ratio of DC circuit breaker,which provides reference for power plants with similar problems.
