低零序阻抗接地变压器的设计探讨

Discussion on Low Zero Sequence Impedance Grounding Transformer

本文作者通过实例,介绍了当接地变压器零序阻抗值较小时,在设计、工艺及生产制做等方面出现的问题,给出了针对性的解决方案,并提出了相应的注意事项。

In this paper,the conventional calculation method of grounding transformer is introduced,and the problems in design,process and manufacture of grounding transformer when the zero-sequence impedance requirement is low are introduced by examples,the solution is put forward and the corresponding matters needing attention are given.
