Circuit breaker short-delay opening control method and circuit breaker

The invention discloses a short-delay opening control method for a circuit breaker, and belongs to the technical field of low-voltage circuit breakers. According to the short-delay opening control method for the circuit breaker, the opening execution time in each opening process of the circuit breaker is detected and recorded, and the delay time before the controller microprocessor sends the opening instruction is dynamically adjusted according to historical data, so that the short-delay protection time of the circuit breaker can approach a set value as much as possible. The invention further discloses a circuit breaker. Compared with the prior art, the short-delay opening time of the circuit breaker can be dynamically adjusted according to the actual situation, and the safety and reliability of the system are improved. 本发明公开了一种断路器短延时分闸控制方法，属于低压断路器技术领域。本发明断路器短延时分闸控制方法对断路器每次分闸过程中分闸执行时间进行检测和记录，并依据历史数据来动态调整控制器微处理器发送分闸指令前的延迟时间，以使得断路器短延时保护时间能够尽可能趋近于设定值。本发明还公开了一种断路器。相比现有技术，本发明能够根据实际情况对断路器的短延时分闸时间进行动态调整，提高系统的安全可靠性。
