摘要
电子式互感器是智能变电站中的核心元件,发挥着至关重要的作用。但相对于传统电磁式互感器,电子式互感器对温度的影响较为敏感,在低温地区应用时容易出现精度和可靠性下降的问题。本文针对电子式互感器在低温环境下的应用问题,通过实验测试了典型电子式互感器在低温环境下的运行规律,并在实验的基础上提出应对低温电子式互感器性能下降问题的措施及研究方向。
Electronic transformers are the key components in smart substation and play a crucial role. However, compared with traditional electromagnetic transformers, electronic transformers are more sensitive to temperature. When used in low - temperature regions, accuracy and reliability are liable to drop. In this paper, in terms of the application of electronic transformers in low temperature environment, the typical electronic transformer＇ s operating law is tested in low - temperature environment through experiment, and measures to deal with performance degrada- tion for low - temperature electronic transformer are put forward as well as the research direction on the basis of the experiment.
