新型环保绝缘气体灭弧性能数据集

本数据集主要面向电力装备环保化与绿色电网建设的重大需求，旨在系统评估新型环保绝缘气体CF3SO2F及其与N2的混合气体作为强温室气体SF6潜在替代品的绝缘与灭弧性能。数据集源于系统的理论计算与实验研究，通过第一性原理计算、吉布斯自由能最小化方法、汤逊散射实验以及玻尔兹曼方程解析求解等多种方法产生。内容主要包括CF3SO2F/N2混合体系在高温下的分解产物平衡组成与关键物性参数、放电等离子体中的电子数密度空间分布、以及在不同温度、气压与混合比条件下的热态折合击穿场强。涵盖该气体从微观分解机理、中观放电动力学到宏观绝缘强度的关键性能图谱，为新型环保绝缘气体的研发、电气设备（如GIS、断路器）的设计优化与仿真、以及放电物理机理研究提供了不可或缺的基础数据支撑。

This dataset is developed to address the critical demands for environmentalization of power equipment and the construction of green power grids, aiming to systematically evaluate the insulation and arc-quenching performance of the environmentally friendly novel insulating gas CF3SO2F and its mixture with N2 as potential alternatives to the potent greenhouse gas SF6. The dataset is generated from systematic theoretical calculations and experimental studies, adopting multiple methods including first-principles calculations, Gibbs free energy minimization method, Townsend scattering experiments, and analytical solution of the Boltzmann equation. Its core content covers the equilibrium composition of decomposition products and key physical property parameters of the CF3SO2F/N2 mixture system at high temperatures, the spatial distribution of electron number density in discharge plasma, as well as the thermal reduced breakdown field strength under varying temperatures, air pressures and mixing ratios. It includes key performance maps of this gas spanning from microscopic decomposition mechanism, mesoscopic discharge dynamics to macroscopic insulation strength, providing indispensable foundational data support for the research and development of novel environmentally friendly insulating gases, the design optimization and simulation of electrical equipment such as GIS and circuit breakers, and the investigation of discharge physical mechanisms.
