一起干式空心串联电抗器的故障分析
摘要
通过对广东省一起干式空心串联电抗器故障的分析和所进行的试验论证
发现干式空心串联电抗器在运行时温度分布不均匀
存在局部过热现象
现用的温升试验方法不足以反映空心串联电抗器绕组的实际温升情况
建议干式空心串联电抗器的温升试验应检测电抗器绕组的最高温升
作为电抗器温升试验的结果。
Abstract
Through analyzing and test a dry-type air-core series reactor fault in Guangdong Province
the uneven temperature distribution of one dry-type air-core series reactor was found
it was partial overheating
the usual temperature rise examination couldn′t reflect the real temperature of such a reactor winding totally.It is suggested that the detected highest temperature of the reactor winding should be regarded as the final result of temperature rise test for such kind of reactor.
