高压电缆终端多界面应力锥的优化设计

Optimum Design of Multi-Interface Stress Cone of High Voltage Cable Terminal

针对传统方法设计的应力锥无法达到标准要求的特点,提出一种基于有限元计的方法,并通过具体实例建立单、多界面的应力锥模型展开电场强度的计算,从仿真模拟计算和试验数据进行详细比较和分析。结果表明,多界面应力锥的设计方案更符合标准要求,有效地提高了应力锥的技术指标,证明有限元方法在电缆终端应力锥的设计和计算中是切实可行的。

The traditional method of stress cone design can not meet the standard requirements,this paper proposes a method based on finite element count and the establishment of a single through concrete examples,multi-interface model of stress cone Computation of electric field strength,from simulation calculations and experiments data detailed comparison and analysis. The results show that the stress cone multi-interface design standard requirements,effectively improve the stress cone Technical indicators prove the finite element method in the design and calculation of cable terminal stress cone is feasible.
