The specific applications are reflected in the following aspects: 1. Optimizing equipment operating parameter design: The company can scientifically formulate the rated operating parameters of equipment and establish an insulation performance early warning mechanism based on current intensity by analyzing the impact of load current intensity on insulation resistance, ensuring that the equipment maintains stable insulation performance even under long-term load fluctuations. 2. Promoting industrial technological progress: This dataset can provide important references for power system operators, equipment maintenance units and scientific research institutions, promoting the R&D and application of innovative technologies such as intelligent insulation monitoring systems and adaptive insulation materials, and driving technological innovations in load-adaptive design of electrical equipment. 1. Data Collection: Real-time recording of insulation resistance test data for electrical control cabinets under different load current intensities, including fields such as test sample number, test time, load current (A), insulation resistance (MΩ), etc. 2. Data Preprocessing: (1) Perform data denoising on the collected data to ensure data accuracy. (2) Aggregate all historically collected data (including this collection) to form dataset X, and calculate the average value of the insulation resistance column in dataset X. 3. Calculation of Linear Regression Slope a and Intercept b: (1) Based on dataset X (with load current as the independent variable and insulation resistance as the dependent variable), use the SLOPE function to determine the slope a based on the least squares method, and use the INTERCEPT function to determine the intercept b. (2) The slope a represents the degree of impact of unit load current change on insulation resistance, and the intercept b represents the insulation resistance value of the electrical control cabinet under the reference load current. 4. Result Application: (1) Calculate the proportional coefficient k: k = |a / average insulation resistance| × 100%. (2) If k ≥ 15%, it is judged as "High Impact"; if 8% ≤ k < 15%, it is judged as "Medium Impact"; if k < 8%, it is judged as "Low Impact".
