摘　　要：近年来多种新型环保气体及其混合气体作为潜在的SF_(6)替代气体受到关注,该文提出将HFO-1336mzz(E)作为绝缘介质应用于电力设备中。结合实验测量的饱和蒸气压数据,采用Antoine方程和气液平衡定律结合的方法研究分析了该气体及其混合气体的饱和蒸气压特性,并与C4-PFN和C5-PFK气体进行了对比。基于饱和蒸气压特性确定充气比例,利用脉冲汤逊实验测量了HFO-1336mzz(E)及其混合气体的电子群参数,并依此确定气体的绝缘强度。研究结果表明,当HFO-1336mzz(E)的比例达到60%时,与CO_(2)或干燥空气的混合气体具有接近SF6的绝缘强度。该文的研究结果为新型环保气体HFO-1336mzz(E)的研究和应用提供重要的基础数据及参考。In recent years,a variety of novel environmental-friendly gases and their mixtures have received attention as potential SF_(6) replacement gases.In this paper,HFO-1336mzz(E)is proposed as an insulating gas to be applied in power equipment.Firstly,based on the experimentally measured saturation vapor pressure data,the saturation vapor pressure characteristics of HFO-1336mzz(E)and its mixtures are investigated and analyzed,using Antoine equation and the gas-liquid equilibrium law,and compared with C4-PFN and C5-PFK gases.Based on the mixing ratio determined by the saturation vapor pressure characteristics,the electron swarm parameters of HFO-1336mzz(E)and its gas mixtures were measured using pulsed Townsend experiments,and the dielectric strength of the gas was determined accordingly.The results show that when the mixing ratio of HFO-1336mzz(E)reaches 60%,the gas mixture with CO_(2) or dry air can achieve the similar insulation strength of SF6.The results provide significant fundamental data and references for further research and application of the new environmental-friendly gas HFO-1336mzz(E).
