This dataset focuses on analyzing the impact of variations in aluminum content in aluminum-metallized film electrodes on the capacitance value of low-voltage self-healing shunt capacitors, and reveals the quantitative relationship between electrode aluminum content and capacitance value. It provides a reliable basis for the company (as a capacitor manufacturer) and external relevant stakeholders to optimize product design, facilitate purchase decisions, formulate industry standards, and more, with notable application value. The specific application scenarios are as follows: 1. Product design optimization: For capacitor manufacturers, based on the quantitative relationship between electrode aluminum content and capacitance value, they can targeted optimize the composition design and manufacturing process of aluminum-metallized films. By adjusting the aluminum content, precise control of the capacitance value can be achieved, improving the performance stability and consistency of products, reducing production costs, and enhancing market competitiveness. 2. Facilitating purchase decisions: For users of low-voltage self-healing shunt capacitors (such as power system units, industrial equipment manufacturers, etc.), understanding the influence law of aluminum content on capacitance value helps them select capacitor products that better meet their actual needs. 3. Assisting industry standard formulation: This dataset provides solid experimental evidence for establishing performance standards and specifications regarding the aluminum content of aluminum-metallized film electrodes for low-voltage self-healing shunt capacitors. The specific data processing and analysis steps are as follows: 1. Data collection: Real-time record the capacitance test data of low-voltage self-healing shunt capacitors under different aluminum contents of their aluminum-metallized film electrodes, including fields such as test sample ID, test time, electrode aluminum content / %, and capacitance value / μF. 2. Data preprocessing: (1) Perform denoising processing on the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the capacitance value field in dataset X. 3. Calculation of linear regression slope a and intercept b: Based on dataset X (taking electrode aluminum content as the independent variable and capacitance value as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. The slope a represents the degree of influence of unit change in electrode aluminum content on capacitance value, and the intercept b represents the capacitance value of low-voltage self-healing shunt capacitors under the reference electrode aluminum content. 4. Result application: (1) Calculate the proportional coefficient k: k = |a / average capacitance value| × 100%; (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
