摘要

针对传统气体绝缘金属封闭开关（GIS）普遍采用SF

气体作为绝缘介质不仅存在极高的全球变暖潜能值，同时由于其结构紧凑、散热面积小易引发过热影响其热稳定性的问题，提出以干燥空气替代SF

气体作为绝缘介质，以252 kV GIS三工位开关为研究对象开展热特性研究。通过电-热-流体多物理场耦合实现GIS三工位开关的稳态热分析，获得三工位开关的温度场分布模型，并通过仿真与温升测试结果的对比，验证了该模型的准确性。采用该模型进一步分析了充气压力和接触电阻对三工位开关温度场分布的影响规律，发现在气压提升至0.7 MPa时温升降低得最为明显。通过分析不同气压下干燥空气和SF

介质中GIS三工位开关温升的对比得到：当干燥空气的压力约为SF

气体压力的3倍时，开关的温升基本相同。该研究可为环保型GIS三工位开关的分析和设计提供参考。

Abstract

To address the issues of high global warming potential associated with the prevalent use of SF

gas as the insulating medium in conventional gas-insulated switchgear（GIS），as well as the overheating problems and thermal stability concerns caused by compact structure and limited heat dissipation area，dry air is proposed as an alternative insulating medium to replace SF

.A thermal characteristic study was conducted on a 252 kV three-position GIS switch. Steady-state thermal analysis of the three-position switch was achieved through electro-thermal-fluid multiphysics coupling，and the temperature field distribution of the switch was obtained. The accuracy of the simulation model was verified by comparing the simulation results with temperature rise test data.Based on the established model，the influence of gas pressure and contact resis

tance on the temperature field distribution of the three-position switch was further analyzed.The temperature rise decreases most significantly when the gas pressure is increased to 0.7 MPa.By comparing the temperature rise of the GIS three-position switch in dry air and SF

under different gas pressures，it was found that when the dry air pressure is about three times that of SF

，the temperature rise of the switch is essentially the same.This study provides a reference for the analysis and design of eco-friendly three-position GIS switches
