The main function of an online transformer oil spectrometer is to monitor the composition and concentration of dissolved gases in transformer oil in real time, in order to determine whether there are faults such as overheating and discharge inside the transformer and ensure the safe operation of the power grid.
Online transformer oil spectrometers are widely used in transformer monitoring in power systems. By detecting the gas composition in transformer oil, the operating status and potential faults of the transformer can be determined, such as partial discharge, overheating, insulation aging, etc. At the same time, the operating environment of the transformer can also be monitored, providing important basis for evaluating the operating status and service life of the transformer.
The working principle of the online transformer oil spectrometer is mainly based on gas chromatography. The system performs sufficient oil circulation to ensure that the analyzed oil sample reflects the true situation inside the transformer. After passing through the oil gas separation device, the characteristic gas is separated from the detected oil sample, and then enters the chromatographic column for gas component separation. Driven by the carrier gas, the gas passes through the gas sensor and converts the gas concentration value into a voltage signal. This voltage signal is converted into a digital sequence signal through a high-precision A/D converter and uploaded to the backend control system through a communication line for detailed analysis, storage, and display.
