六角图法检测变压器差动保护接线的正确性

The Correctness of Using Hexangular Cartographic Mapping to Check the Differential Protection Connecting on Transformer

差动保护是变压器的重要保护 ,若接线错误 ,将对生产经营造成较大的经济损失 .为此 ,详细阐述了六角图测结法及其判别标准 。

Differential protection is an important protection of transformer. If connecting on transformer is wrong, it will cause great economic losses in our production. As a result, hexangular cartographic mapping and its standard of judgement are described in detail, and the application of some living examples to the factory and some points to be noted when mapping are introduced in this paper.
