摘要
在电力系统中发挥重要作用的干式空心并联电抗器发生烧损事故的概率越来越高,严重影响了系统的安全运行。从干式空心电抗器的制造、运行和操作方面分析了其匝间短路产生的内、外部原因。对多种电抗器匝间短路的电气量监测以及温感监测的方法进行了比较。从对比结果看出光纤测温方法具有良好发展优势。
There are increasing burning accidents of the dry-type air-core shunt reactors that have played a great role in power system. The accidents are threatening the system safety seriously. The internal and the external reasons of inter-turn short circuit faults were analyzed in terms of the manufacture,running,and the operation in this paper. The electrical monitoring method and the temperature sensing method of inter-turn short circuit faults were compared. The comparison results showed that the optical fiber temperature measurement had more advantages for development.
