Abstract
The present invention discloses a gas-insulating medium and its application. The gas-insulating medium includes the following components by mass: 8.4-76.7 parts of trans-1,1,1,4,4,4-hexafluoro-2-butene, and 23.3-91.6 parts of octafluorocyclobutane. The gas-insulating medium of the present invention has a dielectric strength better sulfur hexafluoride, and a low liquefaction temperature, and can be applied in a wider temperature range. In addition, the gas-insulating medium in certain compositions has similar properties with a single component insulating gas. when the gas leaks, the ratio of trans-1,1,1,4,4,4-hexafluoro-2-butene and octafluorocyclobutane remains unchanged, and during the maintenance of electrical equipment, trans-1,1,1,4,4,4-hexafluoro-2-butene and octafluorocyclobutane can be directly supplemented according to a certain ratio, without other operations such as analysis and detection. In addition, the gas-insulating medium of the present invention has good environmental protection performance, the GWP value is low, and the ODP value is 0.
