非常规互感器在数字化牵引变电所的应用

非常规互感器与合并单元是未来数字化变电所的重要组成部分,主要解决传统电磁互感器绝缘结构复杂、铁磁饱和严重、安全性差等缺陷。文中介绍了有源和无源2种非常规互感器的原理及构成,对其应用中存在的问题进行了分析,介绍了合并单元的功能模型,提出了一种电子互感器与合并单元在数字化牵引变电所中的配置方案,具有一定的工程价值。

Application of Non-common Transformer in Digitized Traction Substation

Unconventional mutual inductor and merging unit are important parts of future digital substation. They are mainly to solve detects of traditional electromagnetic transformer, such as the complex insulation structure, the serious iron saturation, the poor safety and so on. In this paper, the theory and composition of active and passive unconventional mutual inductor is introduced, the problems of application of electromagnetic inductor are analyzed. In this paper, the function model of merging unit is introd...
