SF6 gas has a century-old history, it is two French chemists Moissan and Lebeau synthetic artificial inert gas in 1900, around 1940, the United States military used it for the Manhattan Project (nuclear military). SF6 is a strongly electronegative gas, and its molecules are easy to adsorb free electrons and form heavy negative ions, weakening the collision ionization process in the gas, so its electrical insulation strength is very high, about 2.5 times the strength of air insulation in a uni

It is generally recommended that users check once every two years, and once every six months in special cases (when the air path pollution is serious). one Matters needing attention SF6 gas quantitative leak detector is a portable precision tester, so pay special attention to the following points: (1). Do not switch the instrument power in dangerous areas! (2). Do not charge in dangerous areas! (3) The instrument prevents collision extrusion and violent vibration during transporta

SF6 electrical products have been widely used in the power sector, industrial and mining enterprises, to promote the rapid development of the power industry. SF6 gas density relay is one of the key components of SF6 electrical switch. It is used to detect the change of SF6 gas density in SF6 electrical equipment body. Its performance directly affects the reliable and safe operation of SF6 electrical equipment. SF6 gas density relays installed in the field often have inflexibility or poor contact

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 undeco

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.
