新型SF6替代气体全氟甲基乙烯基醚的绝缘性能研究
Research on Insulation Performance of a New CF3OCF=CF2 Alternative Gas to SF6
摘要
Abstract
Sulfur hexafluoride(SF6)gas,which is widely used in high-voltage power equipment,has a strong green-house effect.Driven by the goal of'double carbon',it is an urgent task for the power industry to study new environ-mentally friendly SF6 alternative gas.Firstly,170 potential alternative gases to SF6 are screened by high-throughput virtual screening,and a potential insulating alternative gas database consisting of 19 compounds is set up.It is found that CF3OCF=CF2 gas has good comprehensive properties,high insulation strength,with boiling point about-22℃ and GWP is less than 1.Then,focusing on the insulation properties of CF3OCF=CF2 gas,the pulsed Townsend experiment and lightning impact breakdown experiment are performed.The experimental results show that the insulation strength of CF3OCF=CF2 gas is about 0.96～1.02 that of SF6.Therefore,from the perspective of in-sulation performance of CF3OCF=CF2 gas,it has the potential to replace SF6,which verifies the feasibility of the vir-tual screening method.The work in this paper has strongly promoted the theoretical exploration and innovative de-velopment of new environmentally friendly insulating gases.关键词
