摘要
通过对配电网中微机消谐装置、一次消谐阻尼器及消谐型电压互感器等消除电压互感器铁磁谐振设备的特点介绍,对现场几种消谐做法的应用情况进行了分析,提出了在同一配电网中一次消谐和二次消谐并用的几种综合消谐措施,并指出了同时采取限制弧光接地过电压等措施的必要性。
The characteristics of PT resonance elimination equipments in distribution network such as Microcomputer - based resonance elimination, preliminary resonance elimination damper, resonance elimination type PT etc. were introduced. The application conditions of some kinds of resonance elimination method were analyzed. Some comprehensive resonance elimination measures of combination with preliminary and secondary resonance elimination were put forward, and the necessity of adopting the measures of restricting arc light grounding over - voltage was pointed out.
