中文摘要	The influence of the fault current limiter on the recovery voltage of circuit breakers after a short circuiting at the outlet was analyzed using a series resonance fault current limiter in a super grid. The results show that the small equivalent-capacity of inductor greatly increases the rise rate of recovery voltage of the circuit breakers. With an inductance of 20 mH and an equivalent-capacitance of inductor of 2 nF, the rise rate of recovery voltage is increased by 12.35, and the first reference voltage is increased 21.7%. The substantial increase of the rise rate of recovery voltage will seriously affect the breaking capability of the high voltage circuit breakers.
