The Research And Development Of Improved Transformer Line Monitoring Device Based On Error Correction Technology

Transformer Monitoring System with centralized and decentralized type two, this according to a centralized online monitoring mode, the associated transformer line monitoring device research for the online monitoring device problems in regulating transformer line monitoring devices measuring accuracy aspect gives way to improve the rationalization of devices, developed an improved device accordingly.In a centralized online monitoring device, poor reproducibility of the measurement results, the sensor signal distortion, management and monitoring system integrated to determine issues such as lack of capacity, the paper through some hardware control theory, application operational amplifiers and comparators, IEC61850unified communications protocols and intelligent integration of such knowledge theory, to achieve improved device to improve the accuracy of the data line monitoring for accurate monitoring and fault data to provide a basis for judgment. Meanwhile, according to the accuracy of data monitoring impact other aspects, such as the temperature of the sample between samples, automatic detection cycle control and data integration and so on, for the relevant theoretical research and practical design, proposed software and hardware technologies.Eventually the paper developed the improved transformer on-line monitoring device, and uses the device to do the110kV transformer fault determination experiments, which verifies the correctness and feasibility of the device. In addition, the essay carries out the related tests by the device in the110 kV and220kV substation, by the experimental results can prove that the device effectively improves the existing data of online monitoring device measuring the accuracy of the results. Finally aiming at the problems in this paper, we study still put forward the prospect.
