摘要
针对500kV变电站内产生较高工频磁场强度的电气设备——35kV并联电抗器,研究不同类型、不同排列方式下35kV并联电抗器周围工频电磁场分布规律。结果表明,35kV并联电抗器的电磁场强度随着离开电抗器中心距离的增加而降低,三角形排列的电抗器磁场强度大于水平排列的。
Measuring results reveal the exceeding point of power frequency magnetic field intensity concentrated in 35kV shunt reactor in 500kV substation.The different arrangement of 35kV shunt reactors and distributing characteristic of power frequency electromagnetic field are studied.The results show that power frequency magnetic field intensity become much lower with the increasing distance of the 35kV shunt reactor center,and triangular arranged＇s power frequency magnetic field intensity is higher than horizontally-arranged.
