Eovalution of the reliability of power supply of mining enterprises taking into account changes in the technical condition of transformers

Abstract

Relevance: this article is devoted to the analysis of the causes of failure of power transformers and the main impacts. Various cases of failures from substations of mining enterprises are analyzed.

The goal: the extension and increase of the life cycle of a power transformer is achieved through comprehensive research. This is a complex, cognitive and expensive operation, which involves performing research operations in accordance with industry regulatory and technical documents.

Methods: the analysis of factors affecting the reliability of power transformers, as well as a comparison of statistical data on the time between failures of power transformers based on the data obtained during the study, and the study of experience in assessing the impact on the quality of electrical grid elements.

Results: based on the results of the study, an analysis of the technical operating conditions of the power transformer was carried out. A criterion for evaluating the effectiveness of electrical equipment resource management is proposed.
