Transformer fault analysis method and system

Abstract

The invention discloses a transformer fault analysis method. The method includes the steps that a historical faulty transformer is obtained, fault causes of the historical transformer are analyzed, and the fault state quantity of the historical transformer is extracted; a transformer fault database is built, and the fault causes of the historical transformer and the fault state quantity of the historical transformer are stored in the transformer fault database; fault state information of a to-be-detected faulty transformer is obtained; the transformer fault database is inquired, the fault state information of the to-be-detected faulty transformer is analyzed, and fault causes of the to-be-detected faulty transformer are obtained. The invention further provides a transformer fault analysis system. The transformer fault analysis method and system are beneficial to improving power transformer fault judgment efficiency, and a power transformer is prevented from being detached before fault judgment.

Description

technical field [0001] The invention relates to the technical field of transformers, and more specifically, to a transformer fault analysis method and system. Background technique [0002] With the rapid development of my country's industrial economy, the demand for electricity is increasing rapidly, and the requirements for reliable power supply are also increasing. The power transformer is the core equipment of the power system and plays an extremely important role in the safe and reliable power supply of the power grid. A power transformer is a static electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. If the power transformer fails, it will directly affect the power supply. [0003] At present, after the power transformer fails, it is mainly judged by human beings based on the experience of the judges. There are many subjective factors in the judgment results, and most of t...

[0003] At present, after the power transformer fails, it is mainly judged by human beings based on the experience of the judges. There are many subjective factors in the judgment results, and most of the judgments need to reverse the cause of the transformer failure after the transformer is disintegrated. Before the main transformer is returned to the factory
