This paper mainly focuses on the problem that high voltage circuit breaker's closing and opening operation at random phase brings harmful electromagnetic transient effects on the power system. To repress the negative transient effects, a 35kV SF6 phase-control circuit breaker equipped with electromagnetic force driving actuator is designed in this paper. Based on the constructed mathematical and structural...
The paper established the simulation model of series vacuum arc of Vacuum Circuit Breaker (VCB) with double-break using Magneto Hydro Dynamic (MHD) model. To gain the matching characteristics of series vacuum arc, the influence of series different vacuum gaps and interactional magnetic field was analyzed. The distribution of micro-characteristics was depended on the axial magnetic field causing by...
