In theory, SF6 gas is enclosed in sulfur hexafluoride electrical equipment, and there is no possibility of leakage. However, this is not the case, any container equipment can not be 100% sealed, so there must be a leak, sulfur hexafluoride gas leakage is divided into two kinds, one is a natural leak, one is a defect leak, the former is a natural phenomenon, cannot be avoided, and the latter is caused by equipment defects, which can be found and repaired by monitoring means. For the normal leakag

The SF6 microwater meter (Winfoss-P6) uses Finnish Vysala polymeric film resistance-capacitance sensors to measure accurately and reliably over the full range, and has excellent long-term stability. It is not affected by dust particles and most chemical pollution, making it ideal for use in industrial environments.

The SF6 Gas Recovery Purification Purification aeration System (Winfoss-R2) is used to separate air and CF4, low fluoride decomposition from SF6. The separation system is based on the principle of direct liquefaction without oil at high pressure to carry out preliminary liquefaction filtration of recycled SF6 gas, and then rely on the low temperature cooling system to further liquefy and solidify the mixture of gas and liquid in the separator. Nitrogen is slowly separated and discharged, while S

From the basic physical characteristics of SF6 gas, it can be seen that it is relatively easy to liquefy gas compared with air. The state of SF6 gas depends on parameters such as its pressure and temperature.

SF6 electrical equipment internal insulation materials, including SF6 gas and solid insulation materials two categories. SF6 gas is common to all SF6 electrical equipment, while solid insulation materials vary from equipment to equipment, mainly thermosetting epoxy resin, polyester nylon, polyester vinyl, polytetrafluoroethylene, insulating paper and insulating paint. The decomposition temperature and decomposition products of different insulating materials are different. Among them, at 130℃,

Pure SF6 gas is colorless, tasteless, non-toxic, non-flammable inert gas, its own decomposition temperature is greater than 500 ° C, in the normal operation of the decomposition products are very few, but when co-existing with metal materials, at 200 ° C it is possible to occur trace decomposition. As the insulating medium of gas-insulated combined electrical apparatus (GIS), sulfur hexafluoride (SF6) gas has excellent insulation and arc extinguishing performance, and can greatly reduce the size
