Transformer operation state on-line monitoring system and multi-parameter intelligent sensor thereof

Abstract

The invention provides a transformer operation state on-line monitoring system and a multi-parameter intelligent sensor thereof. A multi-type sensor module is connected with an MCU control module through an A/D acquisition module, and a power supply module is connected with the MCU control module; the A/D acquisition module performs analog-to-digital conversion on data acquired by the various sensors and the conditioning circuit units thereof, and sends the data to the MCU control module; the power supply module supplies power to the multi-type sensor module, the A/D acquisition module and the MCU control module; and the bottom of the multi-parameter intelligent sensor is further provided with a magnet. According to the invention, multi-parameter detection can be realized, and fault analysis and judgment are easier; engineering construction of on-site arrangement of power lines and network communication data lines is omitted, the construction period is shortened, and the construction cost is reduced; manpower and material resource expenditure is reduced through on-line monitoring, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of electric power and communication, and in particular relates to an online transformer operating state monitoring system and a multi-parameter intelligent sensor that can be applied to online fault detection of high-voltage transformer equipment in the electric power, petrochemical, and railway industries. Background technique [0002] With the development of the national economy, the development of the power grid is also developing rapidly, which puts forward higher and higher requirements for the safe and stable power supply of the power grid. The operating status of power grid equipment has a great impact on the reliability of the power grid, especially the transformer high-voltage equipment, once it fails, it will often cause huge economic losses and social impacts. Therefore, it is of great significance to improve the operational reliability of power equipment. [0003] Most of the traditional equipmen...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional equipment safety inspections in the power industry use manual periodic inspections. Manual inspections have obvious disadvantages such as high labor intensity and high risk factors.

And because of the sporadic nature of the failure, it is often impossible to find the failure in time, resulting in problems such as missed reports.

[0004] The existing transformer on-line monitoring systems on the market generally need to arrange power lines and data communication cables and have relatively single functions, which cannot really meet the growing detection needs of the power grid; at the same time, the existing transformer on-line monitoring systems usually use fixed The installation of components and transformers is integrated, the engineering volume is large and the installation is complicated, which brings huge installation and maintenance costs

[0005] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
