摘　　要：干式空心并联电抗器因干式无油、安装简单、维护量小、运行成本低等优点受到广泛使用,然而在运行中也存在着不少问题。宝安换流站曾发生一起干式空心并联电抗器因匝间短路着火故障,在此对电抗器接线方式、保护报文和故障录波等情况进行分析,推断故障发展的过程。同时介绍了故障电抗器解剖情况,并对提高干式空心并联电抗器的安全运行可靠性提出了一些建议。The dry-type air core shunt reactor is widely used because of dry oil-free, easy to install, maintenance-free and low cost operation, however, in operation, there are many problems. A dry- type air core shunt reactor caught fire due to short circuit fault between turns in BaoAn converter station. This paper analyses the reactor connection mode, protection message, and fault recorder etc. , infers fault developing process. This paper also introduces disassembling situation of fault reactor and gives some suggestions which can improve safety and reliability of dry-type air core shunt reactor.
