Transformer noise monitoring system

Abstract

The invention provides a transformer noise monitoring system. The transformer noise monitoring system includes noise acquisition devices, industrial control computers, an in-situ switch and an alarm device, wherein the output terminal of each noise acquisition device is in communication connection with the input terminal of each industrial control computer; the first output terminal of the each industrial control computer is in communication connection with the alarm device; the second output terminal of the each industrial control computer is in communication connection with the input terminal of the in-situ switch; the noise acquisition devices are used for acquiring sound wave signals, converting the sound wave signals into audio electric signals and sending the audio electric signals to the industrial control computers; the industrial control computers are used for calculating and analyzing the audio electric signals sent from the noise acquisition devices, determining the fault situation of the transformer and sending a preset alarm signal to the alarm device; the in-situ switch is used for realizing communication connection of the data between the at least two industrial control computers; and the alarm device is used for giving an alarm according to the preset alarm signal.

Description

technical field [0001] The invention relates to the field of transformer monitoring, in particular to a transformer noise monitoring system. Background technique [0002] The power transformer is the core equipment in the AC power system, the core of electric energy conversion and transmission, and the most important and critical equipment in the power grid. With the development of society, large-scale power transformers have been used more and more in residential and public places, and the low-frequency noise generated by transformers in most cases will cause chronic damage to the human body, making people irritable and irritable. Even losing their minds, long-term harassment may cause neurasthenia, insomnia, etc. This puts forward certain requirements for the noise monitoring and analysis of large-scale power transformers and small and medium-sized power transformers. people's attention. [0003] At present, transformer noise monitoring equipment has a single function, p...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a transformer noise monitoring system, which solves the technical problems that the existing transformer noise monitoring equipment has a single function, poor recognition, and lack of intelligent recognition ability, resulting in waste of manpower and low efficiency in manual on-site noise monitoring.
