| 中文摘要:双碳目标的实现需要进一步提高电网的输送能力，对变电站GIS进行扩容是目前电力系统的迫切需求。在GIS扩建过程中，新旧设备之间由接口连接，接口性能对保障扩建后GIS的稳定运行至关重要。该文设计了一种用于220 kV GIS扩建的水平对接接口，并对接口的绝缘性能及温升性能进行了有限元计算。在绝缘计算中，得到了接口的内部电场强度分布，并对对接触头、可拆卸导线等重点部分的场强进行了计算；在温升计算中，得到了导线及外壳的温升分布及温升最大值。研究结果可对GIS扩建过程中接口的绝缘及温升设计提供理论参考。 |

| Abstract:The achievement of the dual carbon goal requires further improvement of the transmission capacity of the power grid， and the expansion of substation GIS is currently an urgent demand for the power system. In the GIS expansion process， the old and new equipment are connected by the interface， therefore the performance of the interfaces is critical to the expanded GIS. In this study， an interface with horizontal docking method for the 220 kV GIS expansion process is designed and the finite element calculation of the insulation and temperature rise performance of the interface is carried out. In the insulation simulation， the internal electric field distribution of the interface is obtained， and the electric field of the key parts such as connecting contacts and removable wires is studied. In the temperature rise simulation， the characteristics of the temperature rise distribution and the maximum temperature rise of the wire and housing are obtained. The research results can provide some theoretical reference for the insulation and heat-resistant design of the interface in the GIS expansion process. |
