How does sulfur hexafluoride cause its harm? It is important to know that there are many industries that need to use SF6 gas, and there are many manufacturers that produce SF6 gas, which are possible emission sources of SF6 gas, and the harm of sulfur hexafluoride is also accompanied by these emission sources. For example, if the manufacturer of SF6 gas is poorly managed in the production process and the technology is immature, it is very likely to lead to the discharge of SF6 gas in the product

The critical temperature is the high temperature at which sulfur hexafluoride gas liquefaction occurs. The critical pressure indicates the gas pressure required for liquefaction to occur at this temperature. Sulfur hexafluoride can only remain gaseous when the temperature is above 45 degrees, under normal conditions of use, it has the possibility of liquefaction, so sulfur hexafluoride can not be used at low temperatures and too low pressure.

Sulfur hexafluoride, molecular formula SF6, relative molecular weight is 146.06, at normal temperature and pressure for colorless, tasteless, non-toxic, non-corrosive, non-flammable, non-explosive gas, density of about 5 times the air, the standard state density of 6.0886kg cubic meters. It is liquid at low temperature and under pressure and becomes a white solid when frozen. The sublimation temperature is -63.9℃, the melting point is -50.8℃, the critical temperature is 45.55℃, and the critical

When the SF6 gas leakage accident occurs, it can quickly deal with the accident, improve the efficiency and quality of the accident handling, establish an emergency rescue mechanism in emergency situations, ensure the safety and rapid evacuation of personnel, so as to minimize the possible injury to personnel and damage to mechanical and electrical equipment.

The density of SF6 gas is indirectly expressed by the pressure value of SF6 gas after temperature compensation. SF6 density relay works under the rated pressure, when the ambient temperature changes, the pressure of SF6 gas also changes, and the temperature compensation device inside the density relay automatically compensates its changed pressure, so that its pressure does not change with the temperature change.
