交流灭磁及其拓展应用

AC De-excitation and Its Expanding Application

本文探讨了交流灭磁应用的关键措施———切脉冲技术。介绍了部分交流开关弧压的试验数据,并着眼于解决问题的实质———利用价廉物美的手段来达到发电机可靠快速灭磁的目的。探讨了一系列行之有效的拓展应用方案 ,如无源灭磁、人工过零、换流熔丝。

This paper discusses the key measure of AC de_excitation application ——canceling pulses technique. The data of the arc voltage tests for some AC switches are introduced. Furthermore, with a view to solve the problem materially——to attain speedy and reliable de_excitation by a cheap and good method, the paper discusses a series of effective expanding application schemes, such as de_excitation in no source,artificial zero_passing, current_changing fuse, and huge PTC etc.
