1. Data Collection:
Real-time collection of dielectric strength test data for electrical control cabinets under different contact resistance values at connection points, including fields such as test sample number, test time, contact resistance (mΩ), dielectric strength (kV/mm), etc.
2. Data Preprocessing:
(1) Denoise the collected data to ensure data accuracy.
(2) Aggregate all historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the dielectric strength field in dataset X.
3. Calculation of Linear Regression Slope a and Intercept b:
(1) Based on dataset X, with contact resistance as the independent variable and dielectric strength as the dependent variable, use the SLOPE function to determine the slope a according to the principle of least squares, and employ the INTERCEPT function to determine the intercept b.
(2) The slope a represents the degree of influence of a unit change in contact resistance on dielectric strength, while the intercept b denotes the reference dielectric strength value under the ideal contact state (0 mΩ).
4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average dielectric strength| × 100%.
(2) If k ≥ 8%, it is classified as "High Impact"; if 4% ≤ k < 8%, it is classified as "Medium Impact"; if k < 4%, it is classified as "Low Impact".
