| Abstract: | The passive high-voltage direct current(HVDC)circuit breaker is important for ensuring reliability of HVDC distribution system,and its working condition and characteristic are particular.In this paper,the working condition and characteristic of HVDC circuit breaker in HVDC transmission and distribution system are analyzed,the arc current characteristic of the breaker is investigated according to test data,and a function for describing arc current characteristic of the breaker is achieved.Conclusion is drawn that small arcing resistance,high varying rate,and high frequency of L1C1 circuit can facilitate breaking larger direct current by HVDC circuit breaker. |
| Keywords: | HVDC(high voltage direct current) passive DC circuit breaker transfer current arcing current characteristic |
