Research and Design of Circuit Breaker for 550 kV Filter Bank
As an important part of UHVDC AC filter bank field
550 kV cut-off filter bank circuit breaker is used in 550 kV rated power system.It can control
measure
protect and switch the transmission line.In this paper
the structural characteristics and performance parameters of 550 kV cut-off filter bank circuit breaker are introduced.The simulation analysis software is used to simulate the arc extinguishing chamber and external insulation electric field of 550 kV cut-off filter bank circuit breaker.According to the working condition requirements of 550 kV cut-off filter bank circuit breaker
the phase selection closing characteristics are studied
and then the seismic calculation and analysis of the whole machine are carried out.The calculation results show that the 550 kV cut-off filter bank circuit breaker is safe and reliable
and the rationality of its design and the correctness of the calculation results are verified by the successful passing of various type tests.
