摘　　要：为了准确了解串补装置周围电场、磁场分布情况及其对围栏温升的影响,对500 kV串补装置典型布置方案进行研究,建立了单相串补模型,借助有限元计算工具,研究了不同高度处电场、磁场的分布,并对围栏中感应电流及损耗进行分析。结果表明,串补装置在围栏处的磁场强度为0级,电场强度为Ⅱ级,围栏温升满足设计要求。在工程设计中,建议增大围栏与平台距离来改善电场分布。In order to accurately understand the electric field and magnetic field distribution around the series compensation(SC)device and its influence on the temperature rise of the fence,the typical layout scheme of 500 kV SC device is studied.The single-phase series compensation model is established.With the help of finite element calculation tools,the distribution of electric field and magnetic field at different heights is studied,and the induced current and loss in the fence are analyzed.The results show that the magnetic field strength and electric field strength of the series compensation device at the fence are grade 0 and grade Ⅱ,and the temperature rise of the fence meets the design requirements.
