When the SF6 pressure drops to the first alarm value, the density relay operates and sends out the "SF6 pressure is low" signal, which should be processed as follows: (1) Check the pressure gauge indication, check whether there is gas leakage, determine whether the signal is correct, SF6 gas serious leakage, such as feeling a stimulating smell, self-discomfort, should take measures to prevent poisoning.

The high pressure of SF6 equipment will shorten the mechanical life of the circuit breaker, and may also cause SF6 gas liquefaction. Sulfur hexafluoride (SF6) is a good gas insulator, and its typical application is used as gas insulation in the high-voltage switchgear of the power supply system. Once sulfur hexafluoride gas encounters high heat, high temperature (such as: electric arc), it will produce by-products such as hydrogen fluoride and sulfur dioxide gas, which coexist with undecomposed

1. Industrial SF6 gas should be filled in a clean and dry cylinder, and it should be vacuumed and cleaned before filling to make it free of oil and water. 2, the volume of the gas cylinder is generally 40L, and the corresponding volume of the gas cylinder can be selected according to the needs of the user. 3. When the design pressure of the cylinder is 8.0MPa, the filling coefficient is not more than 1.17kg/L; When the design pressure of the cylinder is 12.5MPa, the filling coefficient is not

SF6 gas is widely used in medium and high pressure equipment, and its safety has been widely concerned by people. SF6 gas is heavier than air and tends to gather in the low area after leakage, which is easy to cause hypoxia in the lower space. Moreover, SF6 gas generates harmful and toxic gases after high-temperature reaction between insulators and metal substances inside electrical equipment. Once the leak poses a threat to the atmospheric environment and personal safety, In accordance with the

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

Sulfur hexafluoride (SF6) is a colorless, odorless, odorless, non-toxic inert non-flammable gas. Pure sulfur hexafluoride gas is non-toxic, but not life-sustaining. Sulfur hexafluoride is a simple asphyxiant, and exposure to an atmosphere with oxygen content of less than 19.5% can cause dizziness, coma, increased drooling, unresponsiveness, nausea, vomiting, loss of consciousness and even death. Exposure to an atmosphere with an oxygen content of less than 12% will cause unconsciousness without
