METHOD FOR DIAGNOSING A SELF-BLOWOUT CIRCUIT BREAKER, AND DIAGNOSIS APPARATUS |
| 摘要 |
For diagnosing a self-blast circuit breaker (1), a switching operation of the self-blast circuit breaker (1) is triggered to initiate a pressure wave in a filling gas of the self-blast circuit breaker (1). A pressure as a function of time in at least one region of the self-blast circuit breaker (1) which occurs in response to the switching operation is detected. A state of a burn-off nozzle (11) of the self-blast circuit breaker (1) which is burnt off in a switching operation under load for blowing the filling gas onto a switching arc is determined in dependence on the pressure as a function of time. |

1. A method of diagnosing a self-blast circuit breaker, the method comprising:
triggering a switching operation of the self-blast circuit breaker (1) to initiate a pressure wave in a filling gas of the self-blast circuit breaker, detecting a pressure as a function of time in at least one region of the self-blast circuit breaker in response to the switching operation, and determining a state of a burn-off nozzle of the self-blast circuit breaker which is burnt off in a switching operation under load for blowing the filling gas onto a switching arc, the state of the burn-off nozzle being determined in dependence on the pressure as a function of time. |
