摘要
变电站超长串绝缘子测零时,由于分布电压的偏低,可能导致误判。分析了零值绝缘子误判的原因,建议采用测量其分布电压,根据对应的图形来判断绝缘子是否为零值。
When measuring zero to those long insulator clusters in substations,some of their voltages are misjudged as the distributed voltage is too low.In this paper,the main reasons were analyzed,and some relevant countermeasures were presented.The measurement of distributed voltage was recommended,and whether the voltage is zero or not can be judged from the corresponding graphics.
