35kV干式空心电抗器常见故障及处理措施

Common Faults and Treatment Measures of 35kV Dry Air Core Reactor

电力系统中,需要无功补偿、移相、限制短路电流、滤波、平波时,常常会用到一种电感元件,叫作电抗器。其中有一种分类,叫干式空心电抗器,它因为无油结构,杜绝了油浸电抗器漏油、易燃等缺点,保证了运行安全;没有铁芯,不存在铁磁饱和,电感值的线性度好。但是,干式空心电抗器在经过较长时间的运行后,会出现不同的故障,本文针对35kV干式空心电抗器常见故障原因及处理措施进行探讨。

In power system, when reactive power compensation, phase shifting, short-circuit current limitation, filtering and smoothing are needed, an inductive element is often used, which is called reactor. There is a kind of classification,called dry air core reactor, because of its oil-free structure, it eliminates the oil leakage, flammability and other shortcomings of oil immersed reactor, and ensures the operation safety;there is no iron core, no ferromagnetic saturation, and the linearity of inductance value is good. However, after a long time of operation, there will be different faults in the dry-type air reactor. This paper discusses the common fault causes and treatment measures of 35 kV dry-type air reactor.
