摘要
室外GIS设备是变电站中的核心设备,其内部放电故障将会影响变电站供电安全可靠性。针对GIS设备故障危害,结合实际工作经验,对变电站室外GIS设备内部故障发生的原因和检测技术进行归纳总结,以便提高GIS设备故障处理效率。最后,结合变电站GIS设备I母电流互感器间隔气室SF6绝缘气体气压下降故障处理实例,对变电站室外GIS设备故障处理技术措施进行了详细分析,从GIS设备故障处理后投运试验效果可知,所采取的处理方案正确,故障得到有效处理。
Outdoor GIS equipment is a core device in the substation. The internal discharge fault of the equipment affects the security and reliability of substation. Combined with actual work experience, the causes of faults occurring inside the out- door GIS equipment and its detection technique are summarized in order to improve the troubleshooting efficiency of GIS equip- ment. A detailed analysis on the technical measures for outdoor GIS equipments of substation are carried out by taking the droping-down fault of SF6 insulating gas pressure in gas isolation chamber of current transformer as an instance. The results of commissioning test after troubleshooting shows that the measure is correct.
