环保气体HFO-1336mzz(E)及其混合气体的绝缘性能研究
Insulation Performance of Environmental-Friendly Gas HFO-1336mzz(E) and Its Mixtures
摘要
Abstract
In recent years, a variety of novel environmental-friendly gases and their mixtures have received attention as potential SF6 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 CS-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 CO2 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).关键词
