- Sulfur hexafluoride compressors are widely used as insulating media for high-voltage electrical equipment. Sulfur hexafluoride gas insulated fully enclosed switchgear has a much smaller footprint than conventional open high-voltage power distribution devices, and its operation is not affected by external weather and environmental conditions, so it is not only widely used in ultra-high voltage and ultra-high voltage Power system, and has begun to be used in the distribution network (SF6 gas insulated switchgear and ring network power supply unit). The advantages of sulfur hexafluoride gas-insulated pipeline transmission line are low dielectric loss, large transmission capacity, and can be used in high-drop occasions, so it is often used in the outlet of hydropower stations to replace conventional oil-filled cables. SF6 gas insulated transformer has the advantages of fire and explosion protection. This kind of distribution transformer is especially suitable for power supply in densely populated areas and high-rise buildings. SF6 gas-insulated ultra-high voltage transformers have been successfully developed, and fully gas-insulated substations will be a direction for the development of substation technology.
- Sulfur hexafluoride gas is chemically stable. Slightly soluble in water, alcohol and ether, soluble in potassium hydroxide. Does not react chemically with sodium hydroxide, liquid ammonia and hydrochloric acid. Does not react with copper, silver, iron, and aluminum in a dry environment below 300°C. Below 500℃, it has no effect on quartz. It reacts with metallic sodium at 250°C, and reacts in liquid ammonia at -64°C. It will be decomposed when mixed with hydrogen sulfide and heated. At 200°C, in the presence of certain metals such as steel and silicon steel, it can promote its slow decomposition. Because the density of sulphur hexafluoride is almost five times that of air, people who inhale sulphur hexafluoride will speak with longer wavelengths and lower frequencies, and their speech will become as powerful as a man, while helium is the opposite. After inhalation, the wavelength becomes shorter and the frequency becomes higher, and the voice becomes thin and weak like a woman. With the continuous acceleration of the urban construction process, the supporting power facilities, equipment scale and capacity are increasing day by day, especially the GIS electrical equipment has its own small footprint, high operational reliability, rapid installation, and small maintenance workload in new substations. It has been widely used, which has led to an increase in the use of SF6 gas to a certain extent. If SF6 is improperly controlled during use or leaks when recovering gas, it will not only pollute the environment, but also cause the normal operation of electrical equipment and employees. The SF6 gas recovery device is one of the essential key equipment for maintenance, and the SF6 compressor and vacuum pump are the core of the equipment. Nanjing Hunter introduced foreign technology, and the sulfur hexafluoride compressor produced in Luoyang factory in Henan Province has obtained a number of domestic patented technologies. It has been successfully applied to the sulfur hexafluoride recovery device industry at home and abroad, and has become a high-end recovery device in the gas recovery industry Standard products, please consult our sales staff for details.
