Description

Technical Field

[0002] The transformer oil online monitoring system is mainly used to detect and measure trace fault gases in the oil of oil-immersed power equipment. It can predict hidden dangers of equipment failure at an early stage, avoid sudden accidents, and improve the safety and reliability of power operation. The oil chromatography online detection system consists of a power module, a degassing module, and an analysis and detection module. The degassing module is directly connected to the transformer body or the return oil pipeline through an oil pump, and the transformer oil is introduced into the degassing module. The degassing module sends the gas separated from the oil introduced into the transformer into the chromatographic column, and the chromatographic column separates various characteristic gases for monitoring.

[0003] When installing the oil pump and the oil pipe in the degassing device, the oil pipe is placed in a pre-determined protective pipe. The diameter of the protective pipe should be 3 times the diameter of the object in the pipe. The protective pipe is installed with fixing clamps at intervals of 1 meter along the ground. It is fixed on the ground and the distance from the oil pipe to the oil outlet of the transformer body should be maintained at 8000mm. However, when aligning the oil pipe with the oil pump threaded connection, workers cannot accurately align the oil pipe with the oil pump interface every time during the docking process. If they are tightened without alignment, oil leakage will occur in subsequent use. Therefore, a transformer oil chromatography online monitoring device is proposed to address the above problems.

[0026] The positioning member 2 includes: a sliding column 21 and a triangular plate 22.

[0027] The triangular plate 22 further includes: a receiving groove 220, a pressure spring 221, and a ball-shaped part 222. The receiving groove 220 is opened at the end of the triangular plate 22. The inner wall of the receiving groove 220 is fixedly connected to one end of the pressure spring 221, and the other end of the pressure spring 221 is fixedly connected to the ball-shaped part 222.

[0028] The card connector 1 8 further comprises a card slot 81. The connecting end of the card connector 1 8 is provided with a card slot 81, and the card slot 81 is card-connected with the card connecting end of the card connector 2 9;

[0029] The clamping end of the clamping joint 2 9 is fixedly connected with an elastic clamping head 91, and the elastic clamping head 91 is clamped to the inner wall of the clamping slot 81;

[0030] The sleeve 5 includes: a limiting slide groove 50, a positioning groove 501, a rotating ring 51, and a limiting handle 52. A limiting slide groove 50 is provided on one side of the sleeve 5, and the limiting slide groove 50 is slidably connected to the end of the positioning member 2.

[0032] Working principle: before aligning and tightening the connecting flange 41 on the oil pipe 4 with the connecting port 3, it is necessary to sleeve the sleeve 5 on the connecting port 3, and then push the clamp joint 1 8 and the clamp joint 2 9 to move toward the middle of the connecting port 3. When the clamp joint 1 8 is pushed to move, the clamp joint 1 8 drives the sliding column 21 on the left to move, and the clamp joint 2 9 drives the sliding column 21 on the right to move. The sliding column 21 will slide under the restriction of the limiting slide groove 50. When the ball-shaped part 222 set at the end of the triangular plate 22 moves to the position of the positioning groove 501, the compressed pressure spring 221 will drive the ball-shaped part 222 to insert into the positioning groove 501.

At this time, the elastic clamping head 91 will be inserted into the card slot 81 and clamped, and the ball piece 222 will be inserted into the positioning slot 501, so that the movement of the card joint 1 8 and the card joint 2 9 is in an equidistant state, so that the sliding columns 21 on both sides slide synchronously to the equidistant position of the socket 5, avoiding the socket 5 and the card joint 1 8 and the card joint 2 9 after the clamping are offset; at this time, align the connecting flange 41 with the limiting sleeve 71 and clamp it, so that the connecting flange 41 can be pressed, so that the pressure head 7 drives the telescopic rod 6 to slide, so that the connecting flange 41 in the limiting sleeve 71 is at the same center of the circle as the socket 5 and the connecting port 3, and then the limiting sleeve 71 is rotated, and the limiting sleeve 71 drives the connecting flange 41 to rotate, so that the connecting flange 41 is tightened on the connecting port 3.

[0033] By inserting the ball part 222 into the positioning groove 501, the movement of the clamping joint 1 8 and the clamping joint 2 9 is in an equidistant state, and the sliding columns 21 on both sides slide synchronously to the equidistant positions of the socket part 5, avoiding the socket part 5 and the clamping joint 1 8 and the clamping joint 2 9 to be offset; the socket part 5, the clamping joint 1 8 and the clamping joint 2 9 form a position with the same center of a circle, and then the limiting sleeve 71 is connected to the connecting flange 41, thereby ensuring that the connecting flange 41 and the connecting port 3 are in the same position with the center of a circle, avoiding the misalignment of the two during subsequent tightening, resulting in an uneven tightening process and subsequent leakage.
