摘　　要：1 100 kV超特高压并联电抗器适应中国电力工业发展需求而得到了长足的发展,针对超特高压并联电抗器电磁场及电磁力仿真分析,首先建立了油浸式电抗器有限元3D模型,然后分析了电抗器芯柱结构漏磁现象及磁路,最后计算出了各部件磁密云图及电磁力云图,与实际工况下的实验数据进行对比,结果误差较小,验证了电抗器磁场及电磁力仿真的正确性与有效性,为解决存在的振动及过热问题提供了理论支持。The 1 100 kV UHV shunt reactor has been greatly developed to meet the development of electric industry in China. In thispaper, aiming at the simulation analysis of the electromagnetic field and force of the UHV shunt reactor, the finite element 3D modelof the oil-immersed reactor is established firstly. Then, the magnetic flux leakage phenomena and magnetic circuit of the reactor corecolumn are analyzed. Finally, the magnetic cloud and electromagnetic force cloud images of each component are calculated.Comparing with the experimental data under actual working conditions, the results show that the error of the simulation is small,which shows the validity of the simulation results of the reactor magnetic field and electromagnetic force. The results providetheoretical support for solving the existing problems of vibration and overheating of the UHV shunt reactor.
