Description

Technical Field

[0001] The utility model belongs to the technical field of dissolved gas analysis in oil, in particular to a spectral method dissolved gas analysis device in oil. Background Art

[0002] Dissolved gases in oil primarily include oxygen, nitrogen, carbon dioxide, carbon monoxide, and water vapor. These gases can exist in dissolved, reactive, or trace gaseous forms. The presence of these gases can negatively impact the quality and performance of oil. For example, oxygen can cause oil oxidation, leading to oil deterioration; water vapor can reduce the oil's insulation and lubrication properties; and carbon monoxide is toxic and poses a threat to human health. Therefore, accurately analyzing the types and levels of dissolved gases in oil is crucial for oil quality control.

[0003] Publication number CN214310132U, entitled "A Portable Photoacoustic Spectroscopy Dissolved Gas and Trace Moisture Analyzer in Oil," discloses a spectroscopic dissolved gas analyzer in oil. The instrument utilizes a wire-fixing assembly and a rubber strip to squeeze the connection points, preventing the connection wires from detaching and ensuring normal operation. The rubber strip provides excellent sealing stability, but during use, the transport of gas within the pipeline causes the pipeline to vibrate. Without further stabilization, the pipeline joints can become loose after long-term use, easily allowing external gas to infiltrate, further reducing the precision of experimental results. Utility Model Content

[0004] The purpose of the utility model is to provide a spectroscopic dissolved gas analysis device for oil. Through the function of the supporting device, the device can stably install the gas conveying pipeline when conducting dissolved gas detection in oil, prevent the loosening between the conveying pipe and the interface due to the vibration generated during gas transportation, avoid the decrease in air tightness and the infiltration of external gas into the detection gas, which leads to errors in the detection results. It solves the problem that the existing gas transportation in the pipeline causes the pipeline to vibrate. If the pipeline is not further stabilized, the pipeline interface will still become loose after long-term use, which easily leads to the infiltration of external gas, and further leads to a decrease in the precision of the experimental results.

[0042] For specific embodiment 1, please refer to Figure 1-7 The utility model is a spectroscopic dissolved gas analysis device in oil, comprising a box body 1, with a dissolved gas analyzer 2 fixed on one side of the box body 1; a plurality of interfaces 3 fixed on the top of the dissolved gas analyzer 2; a plurality of supporting devices 4 fixed inside the box body 1, the supporting device 4 comprising a positioning rod 5, one end of which is fixedly connected to the box body 1; a bracket 6 movably connected to the outside of the positioning rod 5; a fastening frame 7 is fixed to one end of the bracket 6, and a plurality of positioning grooves 8 are opened on both sides of the fastening frame 7; a clamping plate 9 is movably connected inside the fastening frame 7, and a mounting shell 10 is fixed on both sides of the clamping plate 9; a telescopic rod 11 is fixed inside the mounting shell 10, and a spring 12 is sleeved on the outside of the telescopic rod 11; a clamping block 13 is fixed to one end of the telescopic rod 11, and the clamping block 13 passes through the positioning groove 8.
