Description

Technical Field

[0001] This application relates to the field of online oil chromatography monitoring, and in particular to an online transformer oil chromatography monitoring device. Background Technology

[0002] An online oil chromatography monitor is a device specifically designed for monitoring and analyzing substances in oil products. It is primarily used for online monitoring of oil-immersed power equipment such as transformers. Using gas chromatography technology, it detects volatile organic compounds in oil in real time. The working principle of the online oil chromatography monitor is based on gas chromatography. First, an oil sample is collected by the oil sample acquisition unit. Then, the dissolved gases in the oil are separated by the oil-gas separation unit. The gas sample is then sent to the chromatographic column for separation using a carrier gas. The separated gases are then sequentially detected by the detector. Finally, the detection results are converted into electrical signals and transmitted to the data processing system to form a chromatogram for quantitative and qualitative analysis. In conventional online oil chromatography monitors, after the enclosure is stably installed, monitoring components are installed on the inner wall of the enclosure. These components monitor and analyze substances in the transformer oil. A door is installed on the surface of the enclosure to provide privacy.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional online oil chromatography monitors are prone to overheating after continuous operation in hot environments, as they are often installed outdoors, thus affecting the monitoring performance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

An air outlet box 5 is installed on the surface of the connecting box 4, and a motor 6 is installed on the inner wall of the connecting box 4. A rotating blade 7 is installed at the output end of the motor 6. After the motor 6 is started, the rotating blade 7 is controlled to rotate. The airflow generated by the rotating blade 7 enters from the bottom of the connecting box 4 and exits from the air outlet box 5, so that the air inside the housing 1 circulates and the heat inside the housing 1 is discharged, effectively improving the heat dissipation effect of the online oil chromatograph monitor.

[0024] Reference Figure 2 Both the bottom of the connecting box 4 and the air outlet box 5 are equipped with a shielding net 8. The shielding net 8 shields the connecting box 4 and the air outlet box 5, preventing external impurities or insects from entering the inner wall of the box 1 through the connecting box 4 and the air outlet box 5. The bottom of the connecting box 4 is equipped with a connecting frame 9. Several water filter plates 10 are installed on the inner wall of the connecting frame 9. The water filter plates 10 filter the air entering the connecting box 4, effectively preventing moisture in the air from being sucked into the connecting box 4. Two connecting holes 11 are opened on the surface of the connecting frame 9. The inner wall of the connecting hole 11 is engaged with the locking block 12 on the surface of the connecting box 4.
