Description

Technical Field

[0001] This utility model relates to the technical field of gas analysis devices for oil-immersed power transformers, and in particular to a fault gas analysis device for transformer oil. Background Technology

[0002] In power systems, transformers are among the most critical pieces of equipment. Their normal operation plays a crucial role in ensuring a stable power supply. However, various faults may occur during transformer operation, and fault gas analysis in transformer oil is an important monitoring method. Traditional methods for analyzing fault gases in transformer oil have some limitations. Because the analysis process requires filtering the insulating oil, traditional analytical devices do not facilitate the rapid disassembly and double-fixation of the filter plates inside the filter box, nor do they facilitate the effective cleaning and replacement of clogged or damaged filter plates. This may result in impure insulating oil entering the gas chromatograph, reducing the accuracy of the analysis. Therefore, we propose a fault gas analysis device for transformer oil to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a fault gas analysis device in transformer oil to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fault gas analysis device for transformer oil includes: a transformer; a filter box is arranged on the right side of the transformer; a vacuum degassing tower is arranged on the right side of the filter box; and a gas chromatograph is arranged on the right side of the vacuum degassing tower. Long pipes are fixedly installed on one side of each of the transformer, filter box, and vacuum degassing tower. Connecting pipe one, connecting pipe two, and connecting pipe three are respectively arranged on one side of each of the three sets of long pipes. One end of each connecting pipe is connected to the filter box, the vacuum degassing tower, and the gas chromatograph, respectively. A filter plate is arranged inside the filter box, and two sides of the filter plate are fixedly installed... The filter box has two sets of sliders that are slidably installed inside each side of the filter box. Each side of the filter box has a placement groove and a sliding groove. The sliding groove and placement groove on the same side are equipped with a disassembly assembly. The disassembly assembly includes a frame, a connecting plate that is slidably installed inside the frame, a pull rod and an insert plate that are fixedly installed at both ends of the connecting plate, the insert plate being movably inserted into the filter box, a connecting rod that is fixedly installed on one side of the frame, a sliding plate that is fixedly installed on one side of the connecting rod, and an insert block that is movably inserted into the slider.

An air inlet pipe and a mounting pipe are fixedly installed at both ends of the blowers, respectively. The air inlet pipe extends to the top of the mounting box, and a cooler is fixedly installed at the bottom of the mounting pipe. The cooler is fixedly connected to the mounting box, and an air outlet pipe is fixedly installed on one side of the cooler. The air outlet pipe is connected to the gas chromatograph.

[0011] In this utility model, a fault gas analysis device for transformer oil is provided with a disassembly assembly. By pulling two sets of pull plates horizontally back and forth, the pull rod moves the connecting plate, causing the connecting plate to disengage from the inside of the filter box while squeezing spring one. Then, by pulling the pull plate horizontally to the left, the frame moves the connecting rod while squeezing spring three, causing the connecting rod to move the sliding plate while squeezing spring two. This causes the sliding plate to disengage the insert block from the inside of the slider, facilitating effective disassembly and double-fixed installation of the filter plate. This allows maintenance personnel to replace damaged or clogged filter plates in a timely manner, ensuring the purity of the oil sample entering the analysis system and thus improving the accuracy of the analysis.

The flanges, bolts, and nuts connect three sets of long pipes to corresponding connecting pipes one, two, and three, respectively. The blower drives air through the inlet and installation pipes to the cooler, and finally, the outlet pipe delivers cold air to the gas chromatograph, facilitating effective and rapid cooling of the gas chromatograph. This allows for a uniform temperature drop within the equipment, reducing thermal stress and improving reliability and stability, thus providing protection. The flange connections can withstand significant tensile, compressive, and shear forces, preventing loosening or detachment of the pipes during operation and ensuring the overall sealing and safety of the device.
