Sulfur 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) gas to cool and quench the arc on opening a circuit. Advantages over other

Products and standards. Drafter of the industry standard for insulating gas equipment.Products can be modified according to customer usage and different markets in different countries. In order to be more adaptable to on-site work. EPC.

SF 6 sf 6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 gaz sf6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

5/6/2020Maintenance A common problem with sf 6 switchgear is gas leakage. When leakage occurs, the gas pressure decreases. This reduces the quenching ability of the circuit breaker. To avoid this, always check your breakers often. You can check that via the pointer

Main Greenhouse Gases. Multiple gases contribute to the greenhouse effect that sets Earth's temperature over geologic time. Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs
