Limit circuit fault
First, the fault mechanism and fault current calculation associated with the DC converter are analysed in this study; subsequently, a multiport superconducting fault-current-limiting circuit breaker (SFCLCB) suitable for a flexible DC power grid is designed. The circuit breaker adopts ground drainage to transfer the fault current.CODE: Four LED flashes PROBLEM: Limit circuit fault: either a limit or flame rollout is open FIX: Check for: restricted vent; loose blower wheel; excessive wind; ... Seven LED flashes PROBLEM: Limit circuit lockout FIX: A lockout will occur if the limit or flame rollout is open for longer than 3 minutes. Control will auto-reset after 3 hours.o Break the circuit three times consecutively with a fault current equal to 100% of Icu. o Check that the circuit breaker continues to function normally, that is: o It conducts the rated current without abnormal temperature rise. o Protection functions perform within the limits specified by the standard. o Suitability for isolation is not impaired.
