摘要
绝缘子串采用超长串的750 kV输电线路,其电压分布不均匀尤为突出,直接影响着整条线路的安全运行。文中通过Gambit建立了750 kV输电线路绝缘子串三维电场实体计算模型,采用ANSYS有限元仿真软件确定了绝缘子串有无均压环两种情况下的电位分布,结果可信度高,这对检测低、零值绝缘子,确保输电线路的安全、稳定运行具有重要的意义。
The insulator strings for 750 kV transmission lines are long,which make the voltage distribution of insulator strings uneven much,and directly affect the safe operation of the entire transmission line.The insulator string for 750 kV three-dimensional electric field computation models were established,using the software-Gambit,the voltage distribution was obtained based on ANSYS.The simulation results help to detect the poor insulators and ensured the stable operation of transmission line.
