This dataset focuses on analyzing the impact of main contact material types on the overcurrent withstand capability of contactors, and reveals the quantitative relationship between main contact material types and overcurrent withstand capability. It provides key decision-making basis for the company (as a manufacturer) and external relevant parties, and has important application value, which is specifically reflected in the following aspects:
1. Optimizing contact material selection and design: The company can scientifically select high-performance contact materials by analyzing the influence rules of different materials on overcurrent capability, significantly improve the overcurrent resistance while ensuring excellent conductive performance, and effectively avoid contact welding or material degradation.
2. Promoting overcurrent-resistant material innovation: This dataset can provide support for researchers in the field of electrical contact materials, helping them study the correlation mechanism between material microstructure and overcurrent characteristics, develop new composite contact materials, and promote the development of contactor technology towards higher overcurrent withstand capability.
1. Data collection: Real-time record the overcurrent withstand capability test data of contactors under different main contact material types (such as copper alloys, silver alloys, copper-tungsten alloys, etc.), including fields such as test sample number, test time, main contact material type, overcurrent withstand time/s and other related items.
2. Data preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the overcurrent withstand time field in dataset X.
3. Calculation of multiple linear regression coefficients (a1, a2, a3) and intercept b: (1) Based on dataset X (using the coded values corresponding to different main contact material types as independent variables, and overcurrent withstand time as the dependent variable), use the LINEST function to determine the influence coefficients (a1, a2, a3) of each main contact material type on the overcurrent withstand time of contactors and the intercept b based on the least squares method. (2) Coefficients a1, a2, a3 respectively represent the influence degree of different main contact material types on the overcurrent withstand time of contactors, and the intercept b represents the overcurrent withstand time value of the contactor under the reference main contact material type.
4. Result application: (1) Calculate the influence proportion coefficients k1, k2, k3: k1=|a1/average overcurrent withstand time|×100%, k2=|a2/average overcurrent withstand time|×100%, k3=|a3/average overcurrent withstand time|×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".
