摘要

电缆终端是整个系统的薄弱环节之一。对于充油端子，内部击穿会对周围设备和人员造成严重的伤害。目前，充气插入式交流电缆端子的额定电压可达550kv，大量的工程和应用经验表明，充气插入式交流电缆端子具有无隔离液、安装时间短、设计紧凑等优点。为了将交流电源系统插拔式电缆终端的优点引入直流电源系统，有必要对插拔式直流电缆终端进行仿真建模研究。本文在总结直流电缆附件研制积累经验的基础上，根据直流电缆系统相关型式试验标准，提出了一种200kv插拔式直流电缆终端模型，并对典型条件下的界面电场进行了模拟。

Interface Stress Simulation of 200kV Gas-filled Plug-in DC Cable Termination

The cable termination is one of the vulnerable parts of the whole system. For oil-filled terminations, internal breakdown can produce severe damage to the surrounding equipment and human beings. At present, the rated voltage of gas-filled plug-in AC cable terminations is up to 550 kV and a lot of engineering and application experience shows that the gas-filled plug-in cable terminations have the benefits of no isolation liquids, shorter installation time and compacter design. In order to introduce the advantages of plug-in cable termination of AC power systems for DC power systems, it is necessary to carry out simulation modeling research on plug-in DC cable terminations. Based on the accumulated experience in the development of DC cable accessories, in this paper, a model of a 200 kV plug-in DC cable termination is presented and used to simulate the interfacial electric field under typical conditions according to relevant type test standards for DC cable systems.
