Transformer state monitoring and fault diagnosing system

Abstract

A transformer state monitoring and fault diagnosing system comprises a transformer, a sensor set, an embedded signal acquisition module, an online monitoring and diagnosing unit, a WEB server, etc. Based on a transformer online state acquisition unit, a server browser transformer online state acquisition unit embedded server structure is utilized for establishing a transformer state monitoring and intelligent fault diagnosing network system, and developing a data server of an embedded system. Therefore through a network, a user can obtain operation state monitoring data and an intelligent diagnosing result of each transformer in the network anywhere and anytime through any platform, thereby realizing in-time mastering for operation state of transformer equipment.

Description

Technical field [0001] The invention belongs to the field of transformers, and particularly relates to a transformer state monitoring and fault diagnosis system. Background technique [0002] With the development of the economy and the expansion of the power grid, the demand for electricity in big cities is also increasing. As the key equipment of power system transmission and distribution, transformers have correspondingly higher and higher capacity and voltage levels, which puts forward higher requirements for the safe and reliable operation of power transformers. During the operation of the transformer, its various parts have to withstand the effects of high voltage, strong electric field, large mechanical load, and thermal load. When a certain overcurrent, overvoltage and short-circuit electromotive force impact the transformer suffers from an external short-circuit impact , May cause sudden insulation failure, and more serious, insulation breakdown due to partial discharge ...

AI Technical Summary

Problems solved by technology

Although the status monitoring and fault diagnosis technology of transformers has made some progress, it still cannot meet the needs of actual power transmission and transformation safety.
