摘要
某变电站110 kV GIS设备开关气室的密度继电器多次发出告警信号,在不停电情况下采用SF_(6)气体红外成像、SF_(6)气体检漏等综合手段找出漏点,停电处理并最终多次复查合格。事后对结果分析总结,对常见的GIS设备漏气问题提出了有效的检查手段和预防措施,为电网的安全稳定运行提供了保障。
The density relay of the switch chamber of 110 kV GIS equipment in a substation sends out alarm signals for many times.Under the condition of no power failure,comprehensive means such as SF_(6) gas infrared imaging and SF_(6) gas leakage detection are used to find out the leakage point.Through treatment,and it finally passed multiple rechecks.Then,the results are analyzed and summarized.Effective inspection methods and preventive measures for leakage of common GIS equipment are provided,which provides guarantee for safe and stable operation of power grid.
