Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for quantitative analysis of gases in transformer oil are inefficient, unreliable, and complex, failing to provide timely and accurate measurements necessary for maintaining transformer health and preventing faults.
Innovation Solution
A method involving a separating vessel with a gas space above the transformer oil, where the oil is circulated using a pump to enhance gas diffusion, and a measuring chamber collects gas for concentration measurement using a sensor device, allowing for direct analysis without the need for a separating element and optimizing the measurement period for representative gas concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separating element (membrane) is used to separate gas from transformer oil, then gas can be separated from the oil, but the device complexity increases and the measurement process becomes more time-consuming
Solution Approach 1:
The invention extracts the gas phase from the transformer oil by introducing the oil into a separating vessel where a gas space is already present. The gas automatically separates and rises to the gas space due to density differences, eliminating the need for complex separating elements like membranes. This directly resolves the contradiction by achieving reliable gas separation without adding device complexity.
Solution Approach 2:
The system uses the natural buoyancy and density differences between gas and oil to achieve separation automatically. The pump circulates oil through the separating vessel, and the gas-oil separation occurs spontaneously without requiring external separating elements. This self-service mechanism improves reliability while keeping the device simple.
2Reliability
If a separating element is used to separate gas from transformer oil, then gas separation is achieved, but the measurement time increases
Solution Approach 1:
By extracting gas from the oil into a dedicated gas space in the separating vessel, the system achieves rapid separation based on natural convection and density differences. This eliminates the time-consuming process of forcing gas through membrane separators, thereby reducing measurement time while maintaining separation reliability.
Solution Approach 2:
The pump operates in periodic cycles, circulating oil into the separating vessel, allowing gas to rise and separate, then transferring the accumulated gas to the measuring chamber. This periodic operation optimizes both separation efficiency and measurement speed by batching the separation process.
3Measurement precision
If the transformer oil is circulated in the separating vessel, then gas diffusion is enhanced, but energy consumption increases
Solution Approach 1:
The pump circulates oil only partially through the separating vessel - just enough to ensure adequate gas diffusion and separation - rather than continuously circulating large volumes. This partial action achieves the necessary measurement precision while minimizing energy consumption by avoiding excessive circulation.
4Reliability
If a separating element is used, then gas separation is reliable, but the overall process becomes less efficient
Solution Approach 1:
The invention extracts gas into a separate gas space above the oil in the analyzing chamber, achieving reliable separation through natural convection and density differences. This eliminates the need for time-consuming membrane separation processes, thereby improving analysis efficiency while maintaining separation reliability.
Solution Approach 2:
The separating vessel and measuring chamber are merged into a single integrated system where gas separation and measurement occur in sequence within the same apparatus. This consolidation eliminates the need for separate separation and measurement devices, improving overall productivity while maintaining reliable gas separation.

AI summary
The method involves filling a separation vessel (12) with transformer oil (13), such that a gas chamber (27) remains above the transformer oil in the separation vessel. A measuring chamber is filled with gas from the gas space above the transformer oil. A concentration of a gas component is measured in the measuring chamber with the help of sensor devices (16,17,36,37), particularly arranged in the measuring chamber. The sensor device measure the concentration of one or multiple gas components selected from dihydrogen, carbon monoxide, ethylene and acetylene. An independent claim is also included for a device for quantitative analysis of gases in a transformer oil.
