摘　　要：高压电缆终端应力锥的施工技术直接影响电缆线路的安全性和绝缘可靠性。文章基于110kV电缆终端仿真模型,并采用子模型法优化计算,分析不同作业方式对应力锥电场分布的影响。研究结果表明,在地电位、等电位和中间电位3种作业方式下,应力锥电场变化均在可接受范围内,其中地电位和中间电位作业方式对应力锥电场分布的影响较小。通过优化材料选择、结构设计、仿真计算和施工工艺,可提高电缆终端的运行稳定性和安全性。采用科学的施工工艺和先进的技术手段,如红外成像仪和局部放电检测仪,实时监控施工过程,并通过专业培训保证施工质量,可显著提升高压电缆终端的绝缘性能和长期运行稳定性。The construction technology of high voltage cable terminal stress cone directly affects the safety and insulation reliability of cable lines.Based on the simulation model of 110 kV cable terminal and using sub model method to optimize calculation,analyze the influence of different operation modes on the distribution of stress cone electric field.The research results indicate that the changes in the stress cone electric field are within an acceptable range under three operating modes:ground potential,equipotential,and intermediate potential.Among them,the influence of the ground potential and intermediate potential operating modes on the distribution of the stress cone electric field is relatively small.By optimizing material selection,structural design,simulation calculations,and construction processes,the operational stability and safety of cable terminals have been improved.By adopting scientific construction techniques and advanced technological methods such as infrared imaging and partial discharge detection,real-time monitoring of construction quality is carried out,and professional training is provided to ensure construction quality,significantly improving the insulation performance and long-term operational stability of high-voltage cable terminals.
