摘要
66 kV干式电抗器在750 kV系统电网中对消纳充电功率起着重要的作用,为了保证其正常运行,确保电力系统稳定运行,对新疆乌北750 kV变电站66 kV干式空心电抗器接地扁铁发热现象及时进行了分析,诊断发热的主要原因是在漏磁范围内存在闭合回路。通过改变连接接地支柱的方式,打开此闭合回路,解决了66 kV干式空心电抗器接地扁铁发热问题。
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 Xinjiang a 66 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.
