Three dimensional electric field numerical simulation for highvoltage circuit breaker

运用有限元法对罐式ＳＦ_６断路器断口附近三维电场进行了数值计算，以计算机辅助绘图为支撑，完成了ＳＦ_６断路器三维电场的数值仿真．在三维电场数学模型的建立中考虑了屏蔽罩和并联电容器组的存在；对断路器不同三维剖面的等电位线分布及电场分布情况进行了分析；并将计算结果进行三维图形可视化处理及显示．

In this paper, there-dimensional electric field of circuit breaker has been calculated by applying the finite element method based on the computer aided graphic. The 3-D electric field numerical simulations are achieved. In the mathematical models of the three dimensional electric field, the shield and the parallel capacitors are considered, the potential and the electric field strength distributions of the different three dimensional profiles are analyzed and figured.
