AI Technical Summary

Technical Problem

Traditional circuit breaker condition identification methods rely on hardware contact detection, which is prone to aging problems such as wear, loosening, and poor contact, leading to decreased accuracy, increased probability of misjudgment, and inability to identify intermediate transition positions, resulting in insufficient detection stability and reliability.

Method used

Image processing techniques are used to acquire circuit breaker images. Preprocessing is performed to crop the region of interest, including the circuit breaker body, location indicator, and contact positions. A pre-trained circuit breaker condition classification model is then used to classify the operating conditions. A second verification is performed using confidence scores to ensure the accuracy of the results.

Benefits of technology

It achieves accurate identification of circuit breaker operating conditions, improves the stability and reliability of detection, avoids the aging problem of hardware detection components, can identify three operating conditions and output confidence levels, and reduces the risk of misjudgment.
