干式空心电抗器匝间绝缘试验
摘要
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。
Abstract
In order to detect the inter-turn insulation defect of 35 kV dry-type air-core reactors in 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.
