| 摘 要： | 采用进化论法，对油纸电容式套管均压球进行了电极形状优化，提出了优化策略，约束条件和优化问题的目标函数。优化目标是电极表面电场强度的均匀化和极小化。均压球形状采用多段规则曲线段拟合技术构造，以便于高压套管均压球的大批量制造和检验，此外，采用虚拟介电常数法，计算了大型电力变压器高压套管电容芯子的悬浮电位，通过导电纸模拟验证了该方法的准确性和实用性。

| Abstract: | The evolution strategy is used to optimize the shielding electrode of high voltage bushing. In order to minimize or the uniform the field stress along the shielding electrode, the dummy permittivity is approximately to instead of the conducting sheets of the condenser bushing during the process of optimization. Consideration of the easy production, the figure of the electrode is constructed by several regular curves. The calculation results show that the maximum field stress is reduced 27.9%. |
