How many kV can a SF 6 circuit breaker interrupt?
The first high-voltage SF 6 circuit breaker built in 1956 by Westinghouse, could interrupt 5 kA under 115 kV, but it had six interrupting chambers in series per pole.
When was the first SF 6 circuit breaker made?
The first high-voltage SF 6 circuit breaker with a high short-circuit current capability was produced by Westinghouse in 1959. This circuit breaker in a grounded tank (called a dead tank), could interrupt 41.8 kA under 138 kV (10,000 MV·A) and 37.6 kA under 230 kV (15,000 MV·A).
Why are SF 6 circuit breakers so popular?
The achievement around 1983 of the first single-break 245 kV and the corresponding 420 kV to 550 kV and 800 kV, with respectively 2, 3, and 4 chambers per pole, led to the dominance of SF 6 circuit breakers in the complete range of high voltages. Several characteristics of SF 6 circuit breakers can explain their success:
What is a self-blast SF 6 generator circuit breaker?
The self-blast technique described above is also widely used in SF 6 generator circuit breakers, in which the contact system is driven by a low-energy, spring-operated mechanism. An example of such a device is shown in the figure below; this circuit breaker is rated for 17.5 kV and 63 kA.
