Sulfur hexafluoride is a century-old gas, which was synthesized by two French chemists, Moissan and Lebeau, in 1900 and made commercially available in 1947. At present, sulfur hexafluoride gas is mainly used in the power industry. Sulfur hexafluoride gas is used in four types of electrical equipment as insulation and/or arc suppression: sulfur hexafluoride circuit breakers and GIS, sulfur hexafluoride load switchgear, sulfur hexafluoride insulated transmission lines, sulfur hexafluoride transfor

110-500kV high-voltage circuit breakers using SF6 gas as insulation and arc extinguishing medium have been widely used at home and abroad, but whether the humidity and density of SF6 gas are within the rated range determines whether the insulation and arc extinguishing performance of SF6 gas is effective or not, so the operation regulations of the national power company mandatory provisions: Before and during the operation of the equipment, the density and humidity of SF6 gas must be tested regu

First, SF6 qualitative leak detector The SF6 gas leak detector adopts advanced digital signal processing system, and the detection frequency of the sensor head can reach 2000 times/second. Automatic reset, precise mechanical pump and visual display speed and simplify the leak search process; New sensing head corresponding to other products, improve sensitivity, reliability, service life; Linear design, beautiful and comfortable, more humane.

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
