摘　　要：通过高压原形模拟试验和仿真计算 ,得出配电系统引起PT铁磁谐振的参数配合范围。这一范围的确定 ,对验算使用同类PT的各变电站配电系统是否发生PT谐振过电压 ,如何避开谐振区域 ,提供了科学依据。文中还将试验结论运用于广西玉林配电网的谐振过电压分析。研制出XXQ -W 1型配电网PT消谐装置动作可靠 。Based on original simulation test and simulation calculation, parametric range of resonance overvoltage due to saturated PT in distribution system was obtained. By this determined range, it can be checked that whether PT resonance will happen and how to avoid the resonance area in distribution system using the same type of PT. The test results have been used to analyze the resonance overvoltage due to saturated PT in Guangxi Yulin distribution system. Field operation shows that the developed XXQ-W1 type of PT resonance eliminator has a good effect.
