High-speed rail CIRCUIT BREAKER gas system Introduction
OverviewSulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF6 circuit breakers are widely used in electrical grids at transmission voltages up to 800 kV, as generator circuit breakers, and in distribution systems at voltages up to 35 kV. Sulfur hexafluoride circuit breakers may be used as self contained apparatus in outdoor air insulated substations or may be incorporated into gas insulated switchgear which allows compact installations at high voltages.

our company Model 3 033 R200 SF6 LeakSpy SF6 Gas Detectors. The cordless battery operated LEAKSPY SF6 precisely measures SF6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppmv. The device allows precise localisation of leaks by searching the highest SF6 concentration.

110kV Sulfur Hexafluoride insulation Make money
Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic.SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
