May 22, 2020Working Principle of Sulfur Hexafluoride Breaker. An innovation in the puffer type design of an SF6 circuit breaker is the 'thermal assist' principle. In this type of design, the arc energy is utilised to develop pressure in the arcing chamber for arc quenching. Since this innovation has reduced the energy requirement of the operating mechanism it has become possible to use a spring mechanism for application in SF6 circuit breakers

    LV generator circuit-breakers and other large distribution circuit-breakers (600-6000 A) on board ship are traditionally of the air break type called ACB (air circuit breaker).. This means that the circuit-breaker contacts separate in air. High voltage installations e.g. at 6.6 kV and 11 kV generally use the vacuum interrupter type or gas-filled (sulphur hexafluoride – SF6) breakers.

  • Make/Break Contacts - In Power Circuit Breakers

    In SF6 circuit breakers, the same principle is employed, with SF6 as the medium instead of air. In the “puffer” SF6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of SF6 breakers have been developed for EHV (extra high voltage) transmission systems.

  • High Voltage Circuit Breaker FAQs

    Magnetic and air blast circuit breakers were developed, but these also had several disadvantages. The big problem with these was their bulkiness, making them cumbersome to use. Further research led to the simultaneous development of two types of circuit breakers. One used SF6 gas as the quenching medium and the other used a vacuum.
