摘要
对厂变熔断器保护与单元接线综合差动保护动作选择性配合的问题,作了全面的分析和计算,并结合我国常用的小型水轮发电机额定容量系列,以表格形式给出了保证保护动作选择性的厂变最大额定容量及熔断器的额定电流系列,方便了设计或实用中厂变及保护熔断器的选型。
The maximum capacity and rated fuse current series of the branch transformer is diagrammatically provided to give out the differential protections without false actions after a thorough analysis and calculation for the selectivity of the small capacity series of the mini hydroelectric turbines commonly used in china.These tools facilitate the selection of the proper transformer and its fuse box in a power station.
