[0002] Circuit breakers are important protective devices in power systems. Their main function is to autonomously cut off circuits in the event of overload, short circuit, or other faults to prevent equipment damage and personal safety. Currently, intelligent detection of residual current in circuit breakers requires high environmental requirements and requires the addition of a large amount of historical data for comparative analysis.

[0003] Therefore, the prior art has defects and needs to be improved urgently. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a residual current intelligent detection method, system and storage medium for a circuit breaker, which can more effectively improve the intelligence level and safety performance of the circuit breaker, reduce the impact of the external environment, and improve the accuracy of the acquired residual current through continuous correction.

[0036] Get the residual current of the circuit breaker at the current time node;

[0037] The difference between the theoretical residual current input at the current time node and the residual current of the circuit breaker at the current time node is calculated to obtain the measurement error value at the current time node;

[0038] If the measurement error value at the current time node is greater than the preset measurement error threshold, the residual current of the circuit breaker at the next time node is revised according to the measurement error value at the current time node, and the measurement revision is recorded once;

[0039] Get the total number of measurement revisions;

[0040] If the total number of measurement revisions is greater than the preset second number threshold, the corresponding circuit breaker is set as unqualified.

[0041] A second aspect of the present invention provides a residual current intelligent detection system for a circuit breaker, comprising a memory and a processor, wherein the memory stores a residual current intelligent detection method program for a circuit breaker, and when the residual current intelligent detection method program for a circuit breaker is executed by the processor, the following steps are implemented:

[0076] S204, when the cumulative damage value of the residual current in the corresponding time period is greater than or equal to the preset damage threshold, the circuit breaker tripping information is triggered, and the cumulative damage value of the residual current in the corresponding time period stops accumulating, and the maximum time node corresponding to the cumulative damage value of the residual current in the corresponding time period is extracted;

[0077] S205, subtracting the maximum time node corresponding to the cumulative value of the residual current damage in the corresponding time period from the time node of the circuit breaker tripping to obtain the corresponding circuit breaker tripping reaction time.

[0078] It should be noted that the preset damage weight coefficient table stores the residual currents of various gears and the damage weight coefficients corresponding to the residual currents of the corresponding gears, and the damage indexes of the residual currents at different time nodes in the same time period are accumulated in sequence according to the sequence of the time nodes. For example, the damage indexes of the residual currents in the same time period in the sequence of the time nodes are respectively set to , then the order of accumulating the damage index corresponding to the residual current is ,like If the residual current damage value is greater than or equal to the preset damage threshold, the cumulative damage value of the residual current in the corresponding time period is This ends here.

The time node when the circuit breaker is completely tripped is the time node of the circuit breaker tripping. The time between the time node of obtaining the triggering circuit breaker tripping information and the time node of the circuit breaker tripping is the reaction time of the corresponding circuit breaker tripping.

[0104] Get the total number of measurement revisions;

[0105] If the total number of measurement revisions is greater than the preset second number threshold, the corresponding circuit breaker is set as unqualified.

[0106] It should be noted that the residual current corresponding to the time period numbered 0 is set as the initial residual current, and the corresponding initial residual current is gear 1 in the preset residual current regulating device. The residual current corresponding to the time period numbered 1 is the cumulative value of the initial residual current and the residual current adjustment base, and the residual current corresponding to the time period numbered 1 is gear 2 in the preset residual current regulating device, and so on. The residual current provided by the preset residual current regulating device in each time period is the same, and the residual current in the residual current obtained from the circuit breaker is the actual residual current detected in the circuit breaker.
