摘要
本文通过对深圳电网500kV鹏深甲线多处地线金具发热的原因分析,发现地线金具遭受微风振动影响产生磨损后,在感应电流较大的影响下,造成地线金具发热及灼伤的后果,提出了一些预控措施,有效提高输电线路的安全稳定运行。
Through analyzing the causes of 500kV PengShen line A ground wire fittings fever Of Shenzhen power grid, we find that the wire fittings will be fevered and burning under the influence of the larger induction current after the wire fittings is worn by vibrating of the gentle breeze. Some preventive measures will be put forwarded in order to effectively improve the safe and stable operation of the transmission line.
