35kV电力电缆快插接头关键内部结构设计研究
Research on Key Internal Structure Design of 35kV Power Cable Quick-Connect Joint

在35kV电力电缆快插接头结构设计中，接头内部电场主要靠两端应力锥结构和中间内屏蔽层结构进行处理，避免接头内部出现局部电场强度过高，导致接头高压击穿。本文通过maxwell有限元分析方法，仿真出应力锥和内屏蔽层在不同的设计参数下，接头内部的电场大小及分布情况，找出应力锥和内屏蔽层设计的最优解，为将来此类产品提供设计选择。
In the structural design of 35kV power cable quick-plug joint, the internal electric field of the joint is mainly handled by the stress cone structure at both ends and the inner shielding layer structure in the middle to avoid local high electric field intensity inside the joint, resulting in high voltage breakdown of the joint. In this paper, the maxwell finite element analysis method is used to simulate the magnitude and distribution of the electric field inside the joint under different design parameters of the stress cone and the inner shielding layer, and find the optimal solution for the design of the stress cone and the inner shielding layer, which is the best solution for the future. Products offer design options.
