摘要
35kV干式电抗器在220kV系统电网中对消纳充电功率起着很重要的作用。为了保证其正常运行,确保电力统统稳定运行。对新疆220kV奎屯变电站35kV干式空心电抗器接地扁铁发热原因进行分析,了解到发热是因为在漏磁范围内存在闭合回路,提出改变接地的支柱以打开此闭合回路的措施,实践结果表明该措施有效可行。
In order to prevent the adverse effect caused by dry reactor ground flat iron fever, we will track temperature measurement Through the infrared temperature measurement to xin jiang a 35 kV dry reactor ground flat iron, by the analysis of magnetic flux leakage, circulation and causes fever defects. In view of these defects, put forward the matters needing attention and preventive measures. Practice results show that opening not allowed closed loop due to in the reactor leakage range exists can fundamentally solve the problem of heat circulation.
