ABSTRACT:
A stabilizer (1) includes a first passage (20-23) which connects a compressed gas source (2-3) to the circuit breaker and a second passage (9, 16, 34, 22) which makes the circuit breaker communicate with the atmosphere, these passages being normally closed, as well as means (10) for opening the first passage when the gas pressure in the circuit breaker is lower than a first value and means (31, 13) for opening the second passage when the gas pressure in the circuit breaker is higher than a second value. Application to high-tension air blast circuit breaker.
