Sulfur hexafluoride is a stable gas which is colorless, odorless, nontoxic and noncombustible, SF6 is a strong electronegative gas, molecules of the sulfur hexafluoride are easy to adsorb free electrons to form negative ions with large mass, and the collision ionization process in the gas is weakened, so that the sulfur hexafluoride has high electrical insulation strength which is about 2.5 times of the air insulation strength in a uniform electric field. Since SF6 gas has excellent arc extinguishing and insulating properties and good chemical stability, it was used as an arc extinguishing medium for high voltage circuit breakers since the end of the 50 th century. In the ultra-high voltage and extra-high voltage circuit breakers, SF6 has replaced oil as an arc extinguishing medium and has largely replaced compressed air. From the middle of the 60 s, SF6 is widely used as an insulation medium for high voltage electrical equipment. SF6 gas insulated, fully enclosed switchgear occupies a much smaller area than conventional open high voltage switchgear and its operation is not affected by external weather and environmental conditions, and thus has come into widespread use not only in ultra-high voltage and extra-high voltage power systems, but also in distribution networks (SF6 gas insulated switchgears and ring network power supply units). The SF6 gas insulated pipeline transmission line has the advantages of small dielectric loss and large transmission capacity, and can be used in high drop place, thus being commonly used for outlet of hydropower station to replace the conventional oil-filled cable. SF6 gas-insulated transformers have the advantage of being fire and explosion proof, and are particularly suitable for use in densely populated areas and for supplying power to high-rise buildings.
At present, in the process of pre-testing or fault emergency repair of power equipment such as an SF6 circuit breaker, a current transformer, a GIS air chamber and the like, works such as SF6 gas charging and discharging, SF6 gas humidity and decomposition product testing, SF6 density relay checking and the like are usually carried out, the works all need to connect the air chamber with a pipeline joint on testing equipment through an inflation test joint so as to achieve the purpose of communication, and due to the fact that SF6 equipment is numerous in brand models and types, the types of the pipeline joint are also different (more than ten types of joints are commonly used, including Siemens, ABB, Alston, Western-style, side-hung, Tai-style, like the Gao and the like), the inflation test joint corresponding to the size of the pipeline joint is required to be frequently replaced in the working process, the corresponding inflation test joints are also very many, the application range is small, the working efficiency is reduced, and the working complexity is increased.
