氧化锌避雷器残压检测及信号特征分析

Residual Voltage Detection and Signal Characteristic Analysis of Zinc Oxide Lightning Arrester

氧化锌避雷器是现阶段高压电力系统中承担限制线路雷电过电压和操作过程中电压指标状态任务的重要装置。若出现了过电压现象,短时间内大量的冲击能量会直接倾泻到大地。因此,控制过电压范围是保证高压电力系统的运行能够安全达到有效避雷状态的重要前提条件。应对氧化锌避雷器的残压进行检测,并对其避雷针对地雷器的作用发挥效果进行观察和确认。为了确保观察和分析的有效性,应明确残压检测中的信号特征,并要借助仿真分析手段明确氧化锌避雷器的真实运行状态和应用状态。

The zinc oxide arrester is an important device in the high-voltage power system at this stage to limit the lightning overvoltage of the line and the voltage index state during operation.If overvoltage occurs,a large amount of impact energy will directly pour into the earth in a short time.Therefore,controlling the overvoltage range is an important prerequisite to ensure the safe operation of high-voltage power system to achieve effective lightning protection.The residual voltage of zinc oxide arrester should be detected,and the effect of its lightning protection on mine arrester should be observed and confirmed.In order to ensure the effectiveness of observation and analysis,the signal characteristics in residual voltage detection should be clarified,and the real operation state and application state of zinc oxide arrester should be clarified by means of simulation analysis.
