Self-adaptive protection method for intelligent circuit breaker

The invention provides a self-adaptive protection method for an intelligent circuit breaker, and the method comprises a learning stage: determining an interval value strategy of a self-adaptive current protection constant value of the circuit breaker according to an operation condition in a certain time period, and enabling different operation conditions to correspond to different protection constant values; a protection starting stage: determining a self-adaptive current protection constant value under the current working condition according to the current operation working condition; and anadaptive stage: dynamically adjusting a current protection constant value according to a current change trend in a current time period, and optimizing a protection constant value interval valuing strategy at the same time; the above three stages cooperate with each other to complete the adaptive protection of the intelligent circuit breaker. According to the invention, the current protection constant value of the intellig
