Whale optimization algorithm and miniaturization design of circuit breaker contact spring

In order to overcome the shortcomings of low-voltage circuit breakers such as large volume and poor breaking performance, a mathematical model of contact spring miniaturization is constructed in combination with spring constraints, and an improved whale optimization algorithm (CA-WOA) is proposed for the model optimization. On the basis of the standard whale optimization algorithm (WOA), the Whale Optimization Algorithm is improved by combining the cloud model and adaptive weighting strategy, and the cloud model is introduced to strengthen the algorithm''s global and local search capabilities to avoid falling into local extrema, and then the adaptive weighting strategy is introduced to improve the convergence speed and accuracy of the algorithm. The simulation and comparative analysis of classic test functions show that the improved algorithm has better performance. Furthermore, the improved whale optimization algorithm is used to iteratively optimize the constructed contact spring mathematical model, and the experimental results show that the improved algorithm can effectively reduce the mass and volume of the contact spring and achieve the goal of miniaturization of low-voltage circuit breakers.
