Conversion of common units of sulfur hexafluoride gas GIS, SF6 circuit breakers, SF6 transformers and other equipment will be filled with a certain pressure (density) of SF6 gas, the pressure unit used in the domestic industry is Mpa, and the European, Japanese joint venture manufacturers often use bar and psi and other gas pressure units, which will cause some trouble to everyone. Weavers Xiaobian collection of several units of conversion formulas, listed out for everyone's reference.

Because most of our WINFOSS technicians come from different countries abroad, they use unified English words in product technology development and product document information editing. At the same time, the products are not only sold domestically, but also supporting Siemens switches, ABB switches and some export electrical products are sold in Southeast Asia, Europe and other countries. Thus formed a standardized interface and product appearance packaging information.

DL 408-91 "Electrical Safety Work Regulations" stipulates: 8.2 In the room, when the equipment is filled with SF6 gas, the relative humidity of the surrounding environment should be ≤80%, and the ventilation system must be turned on to avoid SF6 gas leakage to the work area. The SF6 gas content in the working area air shall not exceed 1000ppm. DL/ T639-1997 "Sulfur hexafluoride Electrical Equipment Operation, test and maintenance personnel safety protection Rules" provisions: 4.3.3 Equipment in

A: SF6 is chemically stable and belongs to one of the inert gases. Specifically: 1) Chemical properties: SF6 gas is a very stable and inert gas, it is colorless, tasteless, non-toxic, non-flammable and insoluble in water. It is one of the least reactive gases known, and under normal conditions it does not erode substances that come into contact with it. 2) Physical properties: It is one of the heaviest gases known, density: 6.13g/L, under normal circumstances, it is about 5 times heavier than
