摘　　要：本文主要研究超高压网络短路时暂态电压、电流的波形和频谱．以山东邹县──潍坊５００ｋＶ仿真网络为例，作出了不同点、不同类型、不同弧光电阻短路时暂态电压、电流的波形图和幅度谱图，并列表给出所含的各种频率成份及幅度．对实验结果进行了分析和探讨．它对研究继电保护装置动作性能和故障噪声信号的数学模型有着重要的参考价值．This article presents mainly the studg of the waveform and frequency spectrum analysis for the transient voltage and Current at short circuits of ultra-high voltage network .With-the artificial analog of the houxian-Weifang 500KV power network as example, the waveform diagrem, amplitude specthem diagram at different point, different Kind and through different are resistance are presented. Every frequency and amplitude are also listed. The experimental results are analized and discussed .It has very high refering value for studying the acting character of protection equipment and the mathimatic model of fault -induced noise signals.
