摘要
通过分析沪昆高铁湖南境内娄底南—邵阳北区间20-21#箱变之间的一级电力贯通线故障案例,对利用电量趋势曲线图分析判断短路故障区段的原理进行了阐述。
Through the analysis of Shanghai Kunming High-speed Rail territory of Hunan Loudi South-North Shaoyang between 20 - 21# box transformer substation level power supply through line fault case, this paper discussed the curve using the consumption trend graph analysis and judgment principle of short circuit fault zone.
