摘要
电子式互感器作为数字化变电站过程层的重要组成部分,与传统互感器相比具有绝缘简单、动态范围宽、抗饱和性能强、占地面积小、实现数据输出等优点。介绍了电子式互感器的分类和构成,以及合并单元的功能及其应用,对电子式互感器在数字化变电站中的实际配置和功能应用的提出了建议。
As a key element of the progress level of digital substation,electronic transformer has many advantages compared with traditional transformer,including simplified insulation structure,wide dynamic range,excellent transient characteristic,reductions in size and weight,and digital output etc.The structures and characteristics of electronic transformer and the function and application of a merging unit are introduced.A new opinion of how to dispose electronic transformers and merging units in a digital substation is put forward.
