Sep 2, 2021 · The two main types of circuit breakers are thermal magnetic circuit breakers, which use both thermal effects and magnetic fields to detect an overload and shut off the current,
The arc can be quenched using various techniques and mediums. The SF6 circuit breaker is one of the many types of circuit breakers that uses the SF6 gas as the arc quenching medium to safely break the high voltage circuit. What is an SF6 Circuit Breaker? What is an SF6 Circuit Breaker?
They come in 1 Pole SF6 Circuit Breaker type and 3 Pole SF6 Circuit Breaker. For Special Purpose like Railways , we also offer Double Pole type RDSO Approved 132 KV SF6 Gas Circuit Breakers. They are Gang Operated type , and Individual Pole Operation Type. Few Model Names are 3AP1 FG , LTB 170 , GL312S etc.
The compressed SF6 gas moves out at high speed through the vents. The flow of the SF6 gas quenches the arc. Such type of SF6 circuit breaker uses compressed SF6 gas in a cylinder to quench the arc. Such CB are obsolete and not used anymore. Construction Such SF6 circuit breaker has a fixed contact and moving contact.
They abruptly break the circuit and safely quench the arc. The circuit-breaking part is easy as it is just the separation of contact but the arc that generates afterward which prevents the circuit from breaking and causes damage needs to be quenched as fast as possible. That’s where we use SF6 circuit breaker in HV circuit for arc quenching.
SF6 is an expensive gas so these circuit breakers are costly. Leakage of SF6 from the joints must be continuously monitored. It requires special transportation and maintaining the quality of gas. The SF6 is heavier than oxygen and can cause difficulty in breathing. Recombination and reconditioning of the SF6 gas requires additional equipment.
The operation of SF6 CB is noiseless. SF6 gas is non-toxic in its pure state. SF6 gas is non-flammable, thus no chance of fire hazards. Since its operation is flawless, it requires less maintenance. Disadvantages The decomposed SF6 is toxic. SF6 is an expensive gas so these circuit breakers are costly.
