Online monitoring device for dissolved gas in transformer oil

core functionality

1. Multi-component precision detectionThe following gases can be detected continuously on-line at preset intervals in the transformer oil: Hydrogen (Hydrogen, Hydrogen, Hydrogen, Hydrogen, Hydrogen, Hydrogen, Hydrogen, Hydrogen, Hydrogen)H₂Carbon Monoxide.COCarbon Dioxide.CO₂Methane.CH₄Acetylene (Acetylene, Acetylene, Acetylene, Acetylene, Acetylene, Acetylene, Acetylene).C₂H₂Ethylene.C₂H₄Ethane.C₂H₆), etc. Some devices can also detect micro-water content. Detection mode supports single acetylene rapid detection or full-component simultaneous detection.
2. Real-time condition monitoring and early warning: Continuously tracking the concentration of each gas and the trend of change, when the data exceeds the preset threshold, triggering multi-level warning prompts, timely feedback on the abnormal state of the equipment, to avoid the expansion of the fault.
3. Intelligent Fault Diagnosis: The background software integrates professional analysis models such as David's Triangle Diagramming Method and Triple Ratio Method, which combine with the inspection data to automatically determine whether there are faults in the equipment and the types of faults, and provide a basis for O&M decision-making.
4. Data management and communicationsIt has the function of historical data storage, supports communication modes such as RS485, RJ45, optical fiber, 4G wireless, etc. It is compatible with standard protocols such as MODBUS, IEC61850, etc., so as to realize remote data transmission and centralized monitoring.
5. Extensions and AdaptationsPart of the device can be connected to temperature, load and other sensors to analyze the status of the equipment through multi-dimensional data correlation; it can be adapted to different sizes of oil-immersed equipment, and part of the model provides optional configurations, such as gas monitoring module for the gas collection box.

Key Benefits

1. High detection accuracy and reliabilityThe laser-photo-acoustic spectroscopy technology with narrow linewidth DFB lasers can accurately identify trace gases (e.g., acetylene) on the ppm scale.C₂H₂The measurement accuracy is up to 0.1ppm, which effectively avoids gas cross-interference and provides excellent measurement repeatability and stability.
2. High detection efficiency: Full-component test completed in 60 minutes, single acetylene (C₂H₂The test can produce results in as little as 30 minutes, and multi-point monitoring outputs a set of data every 10 minutes, quickly capturing the signal of gas changes in the early stages of a fault.
3. Installation and runtime friendly: Support non-stop installation, through the oil port sampling, oil samples can be returned to the tank after treatment, to achieve "0 pollution, 0 loss", does not affect the normal operation of the transformer.
4. Low maintenance costsPure physical analysis method, no mechanical loss parts, no need for carrier gas, standard gas and other consumables, no need for frequent calibration and replacement of accessories in the later stage, basically to realize the life cycle of maintenance-free.
5. Highly adaptable to the environmentIt can work stably under the temperature range of - 40℃-70℃ and humidity of 10%-95%, which is suitable for the complex working conditions of power generation, power grid, metallurgy and other industries.
6. Security Redundancy GuaranteeSome models have built-in multiple sets of independent detection units, realizing triple redundancy configuration, avoiding the risk of single-point failure, and enhancing the credibility of monitoring data and the safety of equipment operation.
