METHOD FOR DIAGNOSING A SELF-BLOWOUT CIRCUIT BREAKER, AND DIAGNOSIS APPARATUS |
摘要 |
<p>For the purpose of diagnosing a self-blowout circuit breaker (1), a switching process of the self-blowout circuit breaker (1) is initiated in order to initiate a pressure wave in a filling gas of the self-blowout circuit breaker (1). A time-dependent pressure profile in at least one region of the self-blowout circuit breaker (1), which pressure profile is produced in response to the switching process, is detected. A state of a contact-erosion tip (11) of the self-blowout circuit breaker (1), which contact-erosion tip is eroded in the event of a switching process under load for blowing a switching arc with the filling gas, is determined as a function of the time-dependent pressure profile.</p> |
