4.结果运用：（1）计算影响比例系数k1、k2、k3：k1=|a1/耐受过载电流时间平均值|×100%，k2=|a2/耐受过载电流时间平均值|×100%，k3=|a3/耐受过载电流时间平均值|×100%。（2）若k≥10%，则判定为“高影响”，若5%≤k＜10%，则判定为“中影响”，若k＜5%，则判定为“低影响”。

This dataset focuses on analyzing the effect of contact coating types on the overload current withstand capability of contactors, and reveals the quantitative relationship between contact coating types and the overload current withstand capability. It provides key decision-making basis for the company (as a manufacturer) and external stakeholders, and has important application value, which is specifically reflected in the following aspects:
1. Optimizing contact surface treatment processes: The company can scientifically select high-performance coating materials by analyzing the influence rules of different coating types on overload current capability, significantly improve the overload resistance while ensuring low contact resistance, and effectively suppress arc erosion and material transfer.
2. Promoting functional coating innovation: This dataset can provide support for researchers in the field of surface engineering, helping them study the correlation mechanism between coating microstructure and overload characteristics, develop new composite coating technologies, and promote the development of contactor technology towards higher overload tolerance.

1. Data collection: Real-time recording of test data on the overload current withstand capability of contactors under different contact coating types (such as silver coating, nickel coating, gold coating, etc.), including fields such as test sample number, test time, contact coating type, and overload current withstand time / s.
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 overload current 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 contact coating types as independent variables, and the overload current withstand time as the dependent variable), use the LINEST function to determine the influence coefficients (a1, a2, a3) of each contact coating type on the overload current withstand time of contactors and the intercept b based on the least squares method. (2) The coefficients a1, a2, and a3 respectively represent the influence degree of different contact coating types on the overload current withstand time of contactors, and the intercept b represents the overload current withstand time value of the contactor under the reference contact coating type.
4. Result application: (1) Calculate the influence proportion coefficients k1, k2, k3: k1 = |a1 / average overload current withstand time| × 100%, k2 = |a2 / average overload current withstand time| × 100%, k3 = |a3 / average overload current 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".
