干式空心电抗器匝间绝缘试验

Inter-turn Insulation Test of Dry-type Air-Core Reactor

为了检测35 kV干式空心电抗器运行中是否存在匝间绝缘缺陷隐患,本文利用PSCAD软件对干式空心电抗器采用高频脉冲振荡法进行仿真分析,并对某变电站6台干式空心电抗器进行匝间过电压试验,发现2台设备存在匝间绝缘缺陷,根据现场所测数据验证了仿真分析的可靠性。

In order to detect the inter-turn insulation defect of 35 kV dry-type air-core reactors m the operation, in this paper, the simulation analysis with high frequency pulse oscillation method for the air core reactor is made by the use of PSCAD software and inter--turn test for 6 units of dry type air-core reactors at certain substation is performed, finding two of them have the inter-turn insulation defect. And the simulation and analysis reliability is verified in accordance with the data measured at site.
