摘　　要：超高压交联聚乙烯(XLPE)电缆连接盒是电缆附件中绝缘空间最小、绝缘介质承受电场强度最高、用量最大的电缆附件。提高其绝缘裕度,降低制造成本尤为重要。通过应用ANSYS电磁场分析软件,对现有的超高压XLPE电缆连接盒的整体预制橡胶绝缘体进行电场分析计算。根据计算结果再对其表面电场强度最高的高压屏蔽电极形状进行优化设计。参考空气动力学原理对电极端部形状采用流线型设计,再进行电场分析。综合绝缘裕度和制造成本两方面的因素,确定橡胶预制绝缘体的结构,实现提高绝缘裕度、降低制造成本的目的。The connecting box for supertension XLPE cable is the insulation space in cable accessories highest dielectric withstand the electric field strength, dosage＇s largest cable accessories. Improve its insulation mar- gin, reduce the manufacturing cost is particularly important, by applying ANSYS software analysis of electromagnetic field, the existing supertension XLPE cable connection box overall prefabricated rubber insulation for electric field a- nalysis and calculation. According to the result of calculation and high pressure on the top of the surface electric field intensity shielding electrode shape optimization design. Reference for aerodynamic shape of electrode end on a stream- lined design. Then the electric field analysis. Composite insulation margin and the manufacturing cost two factors, determine the structure of prefabricated rubber insulators, improve insulation margin, reduce the manufacturing cost.
