220kV带纯空气间隙线路避雷器绕击耐受容量及避雷器轻型化潜力研究
带纯空气间隙线路避雷器越来越多应用于线路防雷,尤其是防绕击雷,研究线路避雷器线路的绕击耐受容量及其轻型化具有重要工程应用价值。基于实测的220 kV带纯空气间隙线路避雷器参数建立ATP-EMTP电磁暂态模型,计算了线路避雷器在不同避雷器配置方式和导线电压下的绕击耐受能力。研究表明,当前线路避雷器存在轻型化空间;轻型化线路避雷器需根据线路结构和地形条件进行差异化配置;采用多基杆塔差异化配置方式,避雷器方波容量可降至300 A。本文研究丰富了基于线路避雷器的输电线路差异化防雷策略 ...

测量阀式避雷器电导电流,一般使用临时回路,其中包括整流管装置、滤波电容器、千伏表和微安表。在户外配电装置区域内搬运这些设备有一定的困难,也不方便,而且这种回路在工作时对工作人员也很危险。在我们企业里,研制了可移动的阀式避雷器电导电流测量装置,在颇大程度上消除了上述缺陷。
