摘要
以南方科技大学校园扩建地下敷设10kV电缆线路为例,对越级跳闸的短路现状进行分析,提出了重要电源线路无选择性电流速断保护的改进方案,并分析其改进技术.改进后学校日常供电6年间没有发生越级跳闸现象.
Abstract
Taking the 10kV cable line laid underground in the expansion of the campus of Southern University of Science and Technology as an example,this article analyzes the current situation of short circuit override trip,proposes an improvement plan for non-selective current quick break protection of important power lines,and analyzes its improvement technology. After improvement,there have been no incidents of power override trip in the school's daily power supply for 6 years.
