  • Electrical Systems: SF6 Circuit Breaker Working Principle

    The construction and working principles of SF 6 circuit breaker varies from manufacturer to manufacturer. In the past double pressure type of SF 6 breakers were used. Now these are obsolete. Another type of SF 6 breaker design is the self blast type, which is usually used for medium transmission voltage. The Puffer type SF 6 breakers of single pressure type are the most favoured typesFebruary Basic Electrical Systems Power System System Basics About

  • SF6 Circuit Breaker – Construction, Working Principle and

    Apr 24, 2018Working Principle of SF 6 Circuit Breaker. The contacts of SF 6 Circuit Breaker are surrounded in an environment of SF 6 gas at some pressure. Actually, the dielectric strength of SF 6 gas is directly proportional to its pressure. In 220 kV, 400 kV and 765 kV applications, the gas pressure is maintained at 6.5 bar.

    It is connected to the SF 6 gas reservoir. This unit consists slide vents in the moving contacts which permit the high-pressure gas into the main tank. Gas System – The closed circuit gas system is employed in SF 6 circuit breakers. The SF 6 gas is costly, so it is reclaimed after each operation. This unit consists low and high-pressure chambers with a low-pressure alarm along with warning switches.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    An SF 6 circuit breaker rated 115 kV, 1200 A installed at a hydroelectric generating station. 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 (SF 6) gas to cool and quench the arc on opening a circuit.
