The online transformer oil spectrophotometer is mainly used for real-time monitoring of the composition and content of dissolved gases in transformer oil, to determine whether there are latent overheating, discharge and other faults in the equipment, thereby ensuring the safe and effective operation of the power grid.
The online transformer oil spectrometer is based on the principle of broad-spectrum gas chromatography analysis, and uses differential pressure pumping to suck transformer oil into the oil sample collection unit for oil sample circulation. Under vacuum environment and magnetic stirring, oil and gas are rapidly separated and impurities are removed through cold trap technology. Subsequently, the fault characteristic gas was introduced into a six way valve quantitative tube and entered the chromatographic column under the push of the carrier gas. Different gases were separated due to differences in affinity with the chromatographic column. Gas sensors detect faulty gases one by one in peak order and convert their concentration characteristics into electrical signals. The CPU of the data collector center processes and stores electrical signals, and calculates the components and total hydrocarbon content of the fault gas through embedded data analysis software. Combined with the fault diagnosis system of the backend main control computer, it realizes online monitoring and analysis of transformer faults.
