零序电流互感器二次绕组接线方式的探讨

Discussion on the Connection Mode of Secondary Winding of Zero Sequence Current Transformer

通过分析发电厂厂用6 kV系统单相接地故障电流分布,说明零序电流互感器的特点,论证了零序电流互感器不同二次接线方式的特点,对行业标准的规定和要求进行了分析和论证。

Through the analysis of the current distribution of single-phase grounding fault in 6 kV system, the charac- teristic of zero sequence current mutual inductor was explained, and points of the zero sequence current transformer with different secondary connection mode was demonstrated. Regulations on industry standards and requirements were also analyzed and demonstrated.
