It is known that high purity sulfur hexafluoride has many advantages over other insulating media. It is safe and reliable to use without fire hazard. There is no need to worry about aging and breakdown damage of insulating materials. The operation, maintenance and overhaul of the equipment are convenient. GIS only needs to monitor the pressure or density of SF6 gas. The overhaul cycle is long. The current carrying part and insulation are not affected by atmospheric conditions, which can reduce the maintenance workload.

In the power industry, high purity sulfur hexafluoride is an important medium, which is used as arc extinguishing and insulating gas for closed high-voltage switches. The * * * performance of SF6 gas realizes economical and low maintenance operation of the device. At present, as an insulating and arc extinguishing medium, no other technology can surpass SF6 gas from the technical, economic and ecological perspectives. Sulfur hexafluoride is convenient for assembly, transportation and installation in the factory. Applicable to a wide range of temperatures and pressures.

High purity sulfur hexafluoride has no noise and is free from radio interference. Good insulation, arc extinguishing and cooling characteristics. It is beneficial to reduce the volume and quality of electrical equipment and compact layout. In addition, sulfur hexafluoride decomposes under high pressure and high temperature, and decomposes into hydrogen fluoride, sulfur dioxide, sulfur tetrafluoride, hydrogen sulfide and other toxic substances, which will lead to acute edema of lung tissue, affect the oxygen exchange of lung, and lead to hypoxia and asphyxial death. Therefore, it is urgent to find and solve the problem of SF6 leakage in time.

Therefore, in recent years, with the continuous development of society, economy and switch technology, the complexity of engineering construction has increased, and the miniaturization, maintenance free and intelligent products of switch equipment are increasingly favored. Liming sulfur hexafluoride has good insulation performance and is widely used in high-voltage switchgear at present. It is an ideal insulation and arc extinguishing medium under normal working conditions. It is true that SF6 switch has become the best one among high-voltage switches due to its better insulation advantage.
