摘要
选择性保护可以减少故障对电力系统所造成的影响,提高系统的供电连续性和可靠性。分析了断路器的选择性保护,提出了断路器选型和分析的原则。针对实现选择性会出现的限流技术、电压跌落等问题进行了探讨。
Selective protection can reduce the influence caused by the fault of power system, improve the system power supply continuity and reliability. The selective protection of circuit breaker was analyzed. The principle of circuit breaker selection and analysis was proposed. The problems of limiting current and voltage drop were discussed.
