252kV母线结构的优化设计

The Optimal Design of 252 kV Busbar Structure

为了降低加工制造成本,基于Autocad进行了252 kV母线结构的改进设计,并基于ANSYS的静电场模块计算分析了252 kV母线结构改进前后的内部电场分布.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/min和雷电冲击电压1 050 kV的正负极性各15次的试验.改进后的结构提高了252 kV母线的绝缘裕度,降低了企业的生产成本,每年可节约成本100多万元.

In order to reduce the production cost,an improved design of 252 kV busbar structure was carried out on the basis of Autocad. Then based on ANSYS electrostatic field module,the internal electric field distributions before and after the improved design were revealed. The improved 252 kV busbar structure successfully withstanded the 460 kV / min power frequency voltage and 1 050 kV lightning impulse voltage,separately for 15 times of positive and negative polarity,under 0. 3 MPa relative gas pressure. Due to this improvement,the dielectric margin of 252 kV busbar was enhanced,and more importantly,it was that the production cost of the manufacture was greatly reduced,approximately for one million Yuan per year.
