SF6 Circuit Breaker Definition: An SF6 circuit breaker is defined as a type of circuit breaker that uses sulfur hexafluoride gas to quench electrical arcs. Dielectric Strength: SF6 gas has high dielectric strength, making it highly effective in insulating and quenching arcs.
The non-puffer type sf6 circuit breaker has an Interrupter part, the arc quenching process is performed in this part. It consists of two contacts, the fixed contact and the moving contact. Both these contacts are hollow cylinders. The fixed contact has arc horns connected with it as shown in fig. below.
Sulfur hexafluoride (SF6) circuit breaker is a type of high-voltage electrical switchgear device. it is used for protecting electrical power systems from short circuits and overload conditions. These circuit breakers are commonly employed in medium to high-voltage power transmission and distribution systems.
These breakers are costly due to high cost of SF6 gas. Additional equipment is required to recombine and recondition the gas after each operation. Imperfect joint may lead to leakage of gas. Arched SF6 gas is poisonous. SF6 circuit breakers are most suitable for high power services. They are made up in the range of 3.6KV to 760KV
In Double pressure SF6 circuit breakers the gas is stored at two different pressure levels: high pressure (around 20 bar) and low pressure (around 3-4 bar). This design provides better control over the release of SF6 gas during circuit breaker operation. The double pressure puffer type SF6 circuit breaker is more advanced design.
Dielectric Strength: SF6 gas has high dielectric strength, making it highly effective in insulating and quenching arcs. Types of SF6 Circuit Breakers: These breakers are available in single interrupter (up to 245 kV), two interrupter (up to 420 kV), and four interrupter (up to 800 kV) types.
