Power transformer fault diagnosis method and power transformer fault diagnosis device

Abstract

The invention belongs to the technical field of power transformer fault diagnosis, and discloses a power transformer fault diagnosis method and a power transformer fault diagnosis device. The power transformer fault diagnosis device comprises: a voltage detection module, a temperature detection module, a main control module, a fault detection module, a signal processing module, a data transmissionmodule, a data analysis module, a fault identification module, a fault early warning module, a fault data storage module and a display module. More related operation data are added through the faultidentification module, a classifier is reasonably trained according to the influence weight of data on fault identification, related training data can be input according to requirements to adjust parameters and precision of the classifier, and finally the effect of reasonably identifying transformer faults is achieved. And the data analysis module is more targeted, so that the electric power department can effectively manage a distribution transformer according to the transformer data analysis report, and the level of managing the distribution transformer is improved.

Description

technical field [0001] The invention belongs to the technical field of power transformer fault diagnosis, and in particular relates to a power transformer fault diagnosis method and a power transformer fault diagnosis device. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electron...

AI Technical Summary

Problems solved by technology

However, the existing power transformer fault diagnosis methods and power transformer fault diagnosis devices are inaccurate in fault identification, fault diagnosis models are not accurate, and the possible impact weights of various operating parameters on transformer faults are not clear; at the same time, the analysis of transformer data Inaccurate, poorly targeted

[0003] In summary, the existing problems in the prior art are: the existing power transformer fault diagnosis method and power transformer fault diagnosis device are inaccurate in fault identification, the fault diagnosis model is inaccurate, and the possible influence weight of each operating parameter on the occurrence of transformer faults etc. are not clear; at the same time, the analysis of transformer data is inaccurate and poorly targeted

[0004] The significance of solving the above problems and defects is: when a power transformer fails, it will lead to power supply interruption, which will affect the reliability of power users. If it is an industrial user, it will affect the continuity of production; if it is serious, the transformer will catch fire and explode. Accidents, resulting in serious equipment damage and casualties
