摘　　要：通过对一台4800kV/480kJ冲击电压发生器结合部分110～500kV试品在雷电波下如何满足大负荷范围内的试验要求进行了计算、波形分析和试验研究,提出一种新型的改进回路,从而提高了试验设备的负荷能力,同时也改善了试验波形的畸变,为保证试验达到IEC60—1、60—2有关标准的规定和要求创造了条件.The theoretical calculation, waveform analysis and test investigation are per-formed by a 4 800kV/480kJ impulse voltage generator in combination with some 110~500kV ap-paratus under lightning impulse to meet the test requirements over a large range of load capaci-tance. A new improved circuit is presented to increase the load capability of generator, meanwhile the distorted waveform is improved. All of these would guarantee that tests with this generator could meet the requirements specified in IEC60-1 and 60-2.
