| 摘 要： | 介绍了按照IEC-1259标准进行的500kV气体绝缘变电站中的隔离开关分合短母线充电电流试验，给出了电压测量波形及快速暂态过电压的最大值，平均值。然后对该试验过程进行了数值模拟，并与试验结果比较，给出了测量和数值模拟两种情况下负载测电压的离散傅立叶变换频谱图，从而对了解和深入研究快速暂态过电压的规律提供了重要依据。

| Abstract: | The disconnector of rated voltage 500kV in Gas Insulated Substation is tested for making and breaking buscharging current according to IEC-1259, the measured waves and amplitudes as well as average values of very fast transient overvoltage are given. Numerical simulations for test circuit are carried out and discrete Fourier transform spectra at load side are illustrated for measured and simulation waves. By comparison the results of test and simulation, an important reference is provided for the investigation of very fast transient overvoltage. |
