Abstract: In order to accurately establish the tripping time prediction model of circuit breaker thermal tripping device and improve the stability of the tripping device, an Improved Whale Optimization Algorithm（IWOA） and Support Vector Regression（SVR） modeling method are proposed. In view of the problems of Whale Optimization Algorithm（WOA）, such as easy to get into local optimal solution, slow convergence speed and low convergence accuracy, three strategy improvements are proposed and compared on ten basic test functions. The results prove that the improved algorithm has higher convergence accuracy and faster convergence speed. Then, the prediction model of iwoa-svr tripping time is established, and the production process of circuit breakers is optimized, so as to improve the production efficiency and product quality of circuit breakers.
