Pure SF6 gas is colorless, tasteless, odorless, non-flammable, and chemically stable at room temperature. It is an inert gas. However, in the power industry, because sulfur hexafluoride gas (SF6) is mainly used as insulation and arc extinguishing medium and widely used in high voltage switches and equipment, in the circuit breaker and GIS operation process, due to arc, corona, spark discharge and partial discharge, high temperature and other factors, SF6 gas will decompose, and its decomposition

In the last hundred years, the earth's climate is undergoing a significant change with global warming as the main feature. This global warming is caused by both natural climate fluctuations and the greenhouse effect, which is enhanced by human activities. Reducing greenhouse gas emissions and mitigating climate change is the main goal of the United Nations Convention on Climate Change and the Kyoto Protocol, but China is facing more and more international pressure in reducing greenhouse gas emis

SF6 (sulfur hexafluoride) was synthesized by two French chemists in 1900 and is a man-made gas not found in nature. Due to the unique insulation properties of SF6 gas make it shine in the field of power equipment, through decades of application practice has proved that there is no other medium can be comparable to SF6, is expected to be irreplaceable in the next few decades. It is precisely because of this irreplaceability that we clearly know that SF6 gas is not so "clean" but also use it. We m

Before the use of sulfur hexafluoride gas, we first understand the basic properties of SF6 gas. SF6 gas has a history of more than 100 years, it was synthesized by two French chemists, Moissan and Lebeau, in 1900, and made commercially available in 1947. Sulfur hexafluoride is a volatile compound. Yellow-brown at room temperature, reddish brown in liquid and gas. Strong alpha radioactivity. Melting point 50.75℃. Boiling point 62.3℃. It does not sublimate at atmospheric pressure, but unlike urani

If the purity of sulfur hexafluoride gas is low, its insulation strength will be greatly reduced, and it is easy to be broken down by high voltage when used in electrical insulation, resulting in accidents from the test and research results of relevant departments. So what are the reasons for the impurity of sulfur hexafluoride gas?

SF6 gas is a colorless, odorless, odorless, non-toxic, inert gas that is denser than air and is one of the six greenhouse gases discovered today. SF6 gas is widely used in the high voltage electrical appliance manufacturing industry. Pure sulfur hexafluoride gas is a non-toxic and harmless asphyxiating gas, and there is no toxic sulfur hexafluoride. However, the impure SF6 gas is very harmful to the environment and the human body and equipment. Especially when sulfur hexafluoride gas co
