三相组合式变压器内部引线连接方案探讨

Discussion on Internal Lead Connection Scheme of Three-Phase Combined Transformer

针对三相组合式变压器相间引线结构复杂,引线连接易错问题,以1台180 MVA/220 kV三相组合式变压器为例,从设计、生产环节提出预控方案,保障产品质量。

In view of the complex structure of the three-phase composite transformer′s inter phase leads and the problem of easy lead connection,taking a 180 MVA/220 kV three-phase composite transformer as an example,the control scheme was proposed from the design and production links to ensure the product quality.
