四断口小组滤波器断路器均压措施研究
|
摘要
文中以瓷柱式四断口滤波器断路器电压分布特性展开研究,建立了四断口断路器动态模型和暂态恢复电压仿真电路模型。基于Ansys仿真软件,计算了断口等效电容参数和杂散电容,通过四断口断路器等值电路分析了不同均压措施(电容、电阻、阻容串联、阻容并联)下各断口分压情况。根据静态分压计算结果选择合适的均压电容值和均压电阻值。在动态均压下,由于弧后电阻影响各断口等效参数,通过仿真得出阻容并联对多断口断路器电压分布特性的总体影响规律,提炼出并联阻容优化配置方案。在48 kV四断口断路器下进行不同均压措施下的断口电压分布试验,验证了阻容并联均压措施对动态均压的有效性。
In this paper,a porcelain-core quadruple-break filter circuit breaker is taken as an example to studythe voltage distribution characteristics. The quadruple-break circuit breaker dynamic model and the transient recov-ery voltage simulation circuit model are established. The equivalent capacitance parameters and stray capacitanceof the break are calculated based on the Ansys. The voltage distributions under different voltage-sharing measures(capacitance,resistance,resistance and capacitance in series,resistance and capacitance in parallel)are ana-lyzed through a quadruple-break circuit breaker equivalent circuit. According to the static voltage-sharing calcula-tion results,select proper capacitance and resistance. Under the dynamic voltage-sharing,because the resistanceafter the arc affects the equivalent parameters of each break,the total influence of resistance and capacitance paral-lel connection on the voltage distribution characteristics of the multi-breaker circuit breaker is obtained through sim-ulation,and a scheme for optimal configuration of parallel resistance and capacitance is derived. The voltage distri-bution test under different voltage-sharing measures is conducted under a 48 kV quadruple-break circuit breaker toverify the effectiveness of the resistance-capacitance parallel voltage-sharing measure for dynamic voltage-sharing.
