Temperature Rise Prediction and Uncertainty Analysis of Miniature Circuit Breaker Terminal

Miniature circuit breaker terminal temperature rise is the main parameter of miniature circuit breakers, but also an important parameter of fire prevention, which is of great significance to the actual use of the product. To address this issue, this paper uses GM(1,1) and metabolism GM(1,1) to predict the temperature rise of miniature circuit breaker terminals, respectively, and the prediction results show that metabolism GM(1,1) is better than GM(1,1), which is more satisfying to the engineering needs; at the same time, it analyzes the source of uncertainty in the experimental process, and gives a mathematical model for the uncertainty of measurement. And the validity of the method of this paper is verified with examples.
