摘　　要：介绍新型126 kV三相共箱盆式绝缘子的设计特点,并利用有限元分析软件对绝缘性能和机械性能进行详细计算分析。模拟计算与试验结果表明,该绝缘子接地屏蔽环的设计结构能有效降低三相交接区电场强度;盆式绝缘子的环状凸台设计结构能够承受较高气压值;在浇注过程中,将特殊材质的界面剂涂抹在中心嵌件表面能有效提高嵌件与环氧树脂的黏结强度。该绝缘子顺利通过型式试验,进一步验证了设计结构具有较高绝缘性能和机械性能。This article provides a detailed introduction to the design features of the new 126 kV three-phase common enclosure basin insulator and uses finite element analysis software to perform detailed calculations and analysis of its insulation and mechanical performance.The research results show that by increasing the grounded shielding ring,the electric field intensity in the three-phase junction area can be effectively reduced.The design structure of the basin insulator with a circular convex platform can withstand high gas pressure values.During the casting process,applying a special material surfactant agent on the surface of the central component can effectively improve the bonding strength of the component.The insulator passed successfully a complete set of type tests,further confirming its high insulation performance and mechanical reliability.
