Monitor the equipment's operational status directly within the main control room. Principle of operation for the BHG-YSP Transformer Oil Chromatography Online Monitoring System.

The BHG-YSP Transformer Oil Chromatography Online Monitoring System, during operation, initially uses the oil sample collection unit to circulate the oil path.

Treat the dead oil in the pipeline connections, then perform quantitative oil sampling; the oil-gas separator rapidly separates dissolved gases in the oil and transports them to the six-way valve.

The sample is automatically introduced into the quantitative tube; under the propulsion of the carrier gas produced in-house, the sample gas passes through the chromatographic column for separation and sequentially enters the gas detector.

Data collection unit completes the conversion and collection of AD data, while the embedded processing unit stores and calculates the collected data.

Calculate and analyze, and upload the data to the data processing server via a 100M Ethernet interface or directly through communication protocols.

Data transmission to the provincial company's backend can also be handled and fault analysis performed by the BHG-YSP-03 Monitoring and Early Warning software.
