摘要
Targeted at switchgear's contact temperature prediction, this paper is based on the contact temperature data of high voltage switchgear. Using the Map-reduce model to analyze and process a monitoring point data, the regression model of temperature is established by using multiple linear regression method. The prediction result is analyzed by the criterion of the significance of F regression. The result shows that the longitudinal regression in multivariate linear regression can fit the temperature of the high-voltage switchgear contact well with small deviation, suitable for long-term temperature forecast.
