摘　　要：根据油纸绝缘系统的伏-秒特性,基于有限元法完成了对辅助绝缘装置交流耐压试验下的绝缘裕度的仿真计算,并在此基础上成功研制了一套用于辅助特高压换流变压器阀侧出线装置进行试验的绝缘装置,并通过试验验证了该装置的有效性。According to the V-t characteristics of the oil-paper insulation system, the simulation calculation for the insulation margin under the AC voltage withstand test of the auxiliary insulation device is performed based on the finite element method(FEM). A set of insulation device used to assist the valve-side outlet device of UHV converter transformer is developed based on the simulation calculation. The availability of the device is verified by experiments.
