Shaoxing Power Bureau implants chromatographic monitoring system into transformer “heart”

The transformer is an important equipment in the power transmission and transformation system. Its safe and reliable operation is of great significance to improving the power supply reliability of the power system. Recently, the Shaoxing Bureau installed a transformer chromatography online monitoring system at each of the relevant substations to not only grasp the operational status of the transformer in time, but also detect and track potential failures and automate the diagnosis of transformer operating conditions in real time.

Transformer Chromatography online monitoring system, through the monitoring of transformer and other oil-immersed power high-pressure equipment dissolved in the fault of the characteristic gas content and its growth rate, the fault gas concentration characteristics into electrical signals, the fault diagnosis expert system automatically and quickly Early warning of hidden equipment failure information, to avoid equipment accidents, reduce major losses and improve the reliability of equipment operation.

"The transformer chromatography online monitoring system is like a human hospital to do CT scans, it can detect defects inside the transformer in a timely manner, and be able to continuously monitor, especially to keep abreast of the changes in the defect" Commissioner of the operation of the biotechnology group Ru Huidong According to the introduction, “Using the Chromatography on-line system of transformers, we have also changed from qualitative identification of gas protection to quantitative analysis in the past, and the accuracy has been greatly improved. At the same time, the use of this system is also an important step for the transformer to be periodically overhauled and to go over state maintenance. ”

It is understood that there are currently nearly 30 main transformers installed in the Shaoxing bureau. At the same time, on the basis of the traditional appearance inspection of transformers, oil temperature transcripts and other projects, checking the online background system of transformer chromatography has also become an important part of the day-to-day maintenance of the operating duty watchers.
