摘要
文章介绍了两起电磁式电压互感器烧损情况,通过事故现象及理论计算分析引起电磁式电压互感器的各种原因,并分析了各种解决方案的优越性和局限性,提出了采用一次消谐装置与二次消谐装置二者相互配合使用的解决方案。
The paper introduces two burnout loss of electromagnetic voltage transformer, and analyzes various reasons inducing the burnout through accident phenomenon and theoretical calculation, as well as analyzes superiority and limitation of each solution, thus proposes the adoption of coordinated utilization between the primary and secondary demagnetization apparatus.
