摘要
介绍对现有变电站的传统二次电气控制闭锁回路以及现代微机防闭锁方式的原理、功能、技术发展等相关问题的研究探讨情况,对一些技术问题提出了自己的见解。
The paper introduces working principle, function, technical development and relative problems probed recently in traditionally secondary electric control blocking circuit and modern PC anti-blocking mode in existing substations. The author put forward own understandings on some technical problems.
