摘要

GIS隔离开关分合容性电流过程持续时间长

同时产生高幅值、大陡度、高频率的过电压。采用新研制的光纤式电压测量系统

对1 100 kV GIS隔离开关分合小电容电流试验中的暂态电压进行测量

得到了分合过程中负载电容上"台阶"状电压波形

同时采用EMTP仿真软件对电压波形进行相应的仿真研究

得到了负载上电压的幅值、频率、波形等相应特性。而且试验和仿真结果一致。证明该测量系统可以用于特高压隔离开关分合容性电流用暂态电压的测量。

Abstract

The process of GIS disconnector switching small capacitive current lasted longer

meanwhile

high amplitude

steep and high frequency overvoltage is produced.Using newly developed optical voltage measuring system

to measure the transient voltage in switching small capacitive current test of 1 100 kV GIS disconnector

is introduced in this paper."Step" shape voltage waveform on load capacitor during switching process is obtained.Based on EMTP Simulation Software

the voltage amplitude

frequency

waveform and other relevant load characteristics are obtained.Moreover

the test and the simulation results are consistent

which proved that the measuring system can be used for transient voltage measurement in ultra high voltage disconnector switching capacitive current.
