AI Technical Summary
Technical Problem
Existing failure determination methods for oil chromatography analyzers are based on a single-dimensional assessment, resulting in low accuracy of failure determination results and affecting the safe and stable operation of transformers.
Method used
The failure determination of the oil chromatography analyzer is determined by evaluating the uncertainty of the detection data from at least two assessment dimensions, including response time, accuracy, repeatability, stability, and detection limit, and combining the weighted values and specification limits.
Benefits of technology
This improves the accuracy of failure identification results, avoids interference from accidental factors in a single assessment dimension, and ensures the safe and stable operation of transformers.

Abstract
This invention provides a method, apparatus, device, and storage medium for determining the failure of an oil chromatograph. The method includes: acquiring detection data of dissolved gases in transformer oil within a preset first time period using an oil chromatograph; evaluating the uncertainty of the detection data from at least two evaluation dimensions to obtain evaluation results corresponding to the evaluation dimensions; wherein the evaluation dimensions include at least two of the following dimensions: response time, accuracy, repeatability, stability, and detection limit; and determining the failure determination result of the oil chromatograph based on the evaluation results. This invention avoids the problem of failure determination based on a single evaluation dimension being easily affected by accidental factors, thus improving the accuracy of the failure determination result.
