摘要
分析了GIS中快速暂态过电压VFTO产生的原因及危害,阐述了GIS隔离开关开合母线充电电流试验回路、试验方法及标准要求。介绍了测量VFTO波形的内置圆盘电极及高速数据测量系统,探讨了相关测量技术指标和要求,并针对试验中需要注意问题给出了建议。
The causes and hazards of Very Fast Transient Over-voltage(VFTO)in GIS was analyzed.The test circuit,test method and standard requirements for the Disconnector Switching(DS)Bus-charging current switching test were elaborated.The built in disc electrode and high speed data acquisition system for measuring VFTO waveform were introduced.Relevant measuring technical specification and requirements were discussed.The problems that should be paid attention to in the experiment were briefly analyzed and specific suggestions were given.
