摘　　要：介绍550 kV GIS现场冲击电压试验回路通过VFTO发生器向GIS输出特快速暂态过电压,从而模拟过电压作用下GIS绝缘特性以及验证VFTO抑制技术的实际效果。利用EMTP软件提出一种试验回路仿真建模方法。对比试验数据,仿真结果显示在电压波形的最大峰值和最大峰值时间这种较为极端的条件下和试验数据非常接近,可以认为所述模型基本符合实际情况,具备工程应用价值。The field impulse voltage test circuit of 550 kV GIS can simulate the GIS insulation characteristics under the overvoltage and verify the actual effect of the VFTO suppression technique, by the VFTO generator outputs a transient overvoltage to the GIS. the paper proposed a simulation modeling method of test loop by EMTP software. Compared with the experimental data, the results showed that simulation waveform was very close with experimental data on the maximum voltage and peak time, and results veri？ed that the model was in line with actual situation, and had the engineering application value.
