VFTO
基本例句
特快速暂态过电压¹⁰⁰
Very Fast Transient Over-voltages in GIS are generated during the operations of a circuit breaker and a disconnector.GIS中断路器和隔离开关操作会产生快速暂态过电压VFTO。
VFTOcauses high interturn voltages and internal resonance in the transformer windings, so transformer is the main casualty ofVFTO.VFTO使变压器绕组产生匝间、层间电位差，并发生电压谐振，因此变压器是VFTO最大的受害者。
A test setup for simulatingVFTOis designed,with which fastoscillating impulse voltages with an oscillation frquency up to 10MHz can be generated.本文设计了一套快速暂态过电压的模拟及测量装置，利用所产生的快速振荡冲击电压FOI来模拟快速暂态过电压。
The routine operations of the disconnector in GIS can generate very fast transient overvoltages , which often lead to breakdown in GIS and dielectric failure of the adjacent apparatus.GIS中隔离开关的例行操作将产生波头极陡并伴有高频振荡的快速暂态过电压VFTO，并会造成GIS及邻近设备的绝缘故障，因此研究VFTO作用下SF6气体的击穿特性及机理对进一步提高GIS的可靠性具有重要意义。 |
