【摘要】 建立了126kV、1/3线圈纵磁触头三维电极结构模型,并利用有限元法对考虑了电弧影响的模型进行了三维涡流场仿真.在电流分别处于峰值和过零时,得到了纵向磁场分别在触头片表面和触头间隙中心平面上的分布,以及纵向磁场滞后时间沿径向路径的分布规律.更多还原

【Abstract】 3-Dimentional electrode model of three segments coil axial magnetic field(AMF) contact of 126kv vacuum interrupter is built up,and the 3-D eddy current field in the case of discharge are simulated by the 3-D finite element analysis.The distributions of AMF on the surface of contact plate and mid-gap plane are gotten while current is at the peak and zero.Furthermore the distribution of the AMF phase shift time along the radial path is given.更多还原
