6～10kV电力变压器的联结组别及其选择

Connection Groups and Its Selection of 6～10kV Power Transformer

通过对6~10kV电力变压器常见的3种联结组别的特性分析,得知配电变压器采用D,yn11联结组别在经济运行、提高供电质量、承受不对称负荷能力、快速切除短路故障等方面有着明显优点。

By anglicizing the characteristics of the 6 ~ 10 kV power transformer's three connection groups,we can obtain the D,yn11 connection of the distribution transformer has obvious advantages of the economic operation,high power quality,good asymmetric load capacity and rapid removal of short-circuit fault.
