摘要

对252 kV分支母线结构提出了改进设计

并通过ANSYS商用电场计算软件对更改后的结构进行了电场计算分析。改进后的252 kV母线结构在充气压力为0.3 MPa（表计）下

成功耐受住工频电压460 kV/1 min和雷电冲击电压1 050 kV

正负极性各15次的试验。通过该次改进

提高了252 kV母线的绝缘裕度

并可降低企业的生产成本。

Abstract

This article carries out an improvement design of 252 kV branch busbar structure. The internal electric field distributions after the improvement are calculated by using ANSYS quasi-electric field module.The improved busbar successfully withstands 460 kV power frequency voltage with duration of 1 minute and 1 050 kV lightning impulse voltage with 15 times respectively for both positive and negative polarities under 0.3 MPa relative gas pressure. Due to this improvement

the insulation margin of 252 kV branch busbar is enhanced

and the production cost of the manufacture is greatly reduced.
