Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to a detection device for transformer installation. Background Art

[0002] In modern power systems, transformers are key electrical equipment, and the safety, efficiency, and reliability of their installation and operation are of vital importance. Traditional transformer installation methods mainly focus on basic mechanical installation and simple electrical connections. However, these methods often ignore comprehensive monitoring and preventive maintenance during the post-installation period and operation. For example, during the operation of the transformer, problems such as poor contact and insulation aging may cause local overheating, increasing the risk of equipment failure and safety accidents. To solve the above problems, infrared thermal imaging technology, as an advanced detection technology, has been introduced into the installation and maintenance of transformers. Through infrared thermal imagers, the thermal distribution images of transformer components can be detected without contact, and thermal anomalies caused by electrical or mechanical failures can be discovered in a timely manner, allowing early intervention.

[0003] At present, when using an infrared thermal imager to detect the installed transformer, the fixed installation used for continuous detection can only detect one side, resulting in the inability to detect the temperature of the transformer side, or the detection value is not accurate enough. The current adjustment structure cannot continuously adjust the movement of the infrared thermal imager so that the infrared thermal imager is always facing the transformer for detection. As a result, the angle of the infrared thermal imager must be adjusted separately after the adjustment, causing inconvenience in use. Therefore, a detection device for transformer installation is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application embodiment discloses a detection device for transformer installation. Figure 1-5 A detection device for transformer installation includes a fixed frame 1, a moving block 2 is slidably connected inside the fixed frame 1, the upper end of the moving block 2 is rotatably connected to the mounting rod 3, the upper end of the mounting rod 3 is clamped with the mounting seat 4, an infrared thermal imager 5 is installed on the upper end of the mounting seat 4, the mounting rod 3 is rotatably connected to the support frame 6, one side of the support frame 6 is rotatably connected to the gear 8, one side of the gear 8 is engaged with the gear ring 7, the middle part of the gear ring 7 is fixedly connected to the mounting rod 3, a mounting plate 9 is provided on the upper end of one side of the fixed frame 1, and a plurality of gear plates 91 are equidistantly fixedly connected to the mounting plate 9 near the side of the gear 8.

[0023] The infrared thermal imager 5 is driven to move by the moving block 2, so that the infrared thermal imager 5 moves horizontally to the intersection of the two sides of the transformer, and while moving, the mounting rod 3 drives the fixed frame 6 to move, so that the gear 8 of the fixed frame 6 is intermittently engaged with the gear plate 91 installed on the mounting plate 9 during the movement. When the gear plate 91 is engaged with the gear 8, the gear plate 8 rotates and drives the gear ring 7 to rotate, so that the gear ring 7 drives the mounting rod 3 to rotate, and drives the infrared thermal imager 5 to rotate slightly with the center of the mounting rod 3 as the axis. After the infrared thermal imager 5 rotates, it faces the side of the transformer, so as to detect the temperature of the side by infrared thermal imaging to ensure the accuracy of the value;

[0024] By adopting the above technical solution, the mounting plate 9 is rotated to connect the screw rod 10 on the side away from the gear 8, one side of the screw rod 10 is threadedly connected to the support plate 11, and the lower end of the support plate 11 is fixedly connected to the fixed frame 1. The screw rod 10 is arranged to be rotatable to drive the mounting plate 9 away from the gear 8, and can be adjusted and used when the infrared thermal imager 5 needs to perform temperature detection at various positions on the longer side.

[0025] By adopting the above technical solution, the moving block 2 is threadedly connected to the threaded rod 12, the front and rear parts of the threaded rod 12 are rotatably connected to the inner wall of the fixed frame 1, the front part of the threaded rod 12 is fixedly connected to the output end of the servo motor 13, and the servo motor 13 is fixedly connected to the side wall of the fixed frame 1. The servo motor 13 can be used to drive the threaded rod 12 to rotate, so that the threaded rod 12 drives the moving block 2 to move stably, which is conducive to the mobile use of the infrared thermal imager 5.

[0026] By adopting the above technical solution, fixed grooves are opened on both sides of the upper end of the mounting rod 3, and an elastic sheet 31 is fixedly connected in the fixed groove. One side of the elastic sheet 31 is fixedly connected to a clamping block 32, and the clamping block 32 is trapezoidal. The clamping block 32 is slidably connected to the fixed groove, and the clamping block 32 is clamped to the plug-in frame 41. The upper end of the plug-in frame 41 is fixedly connected to the mounting seat 4.

[0027] When it is necessary to disassemble and replace the infrared thermal imager 5, the block 32 connected to the plug-in frame 41 can be pushed to make the block 32 enter the fixed groove and squeeze the elastic sheet 31 to shrink, and then the plug-in frame 41 can be separated from the mounting rod 3 from above. When reinstalling, it can be placed directly from above the mounting rod 3, so that the plug-in frame 41 squeezes the block 32 during the descent process and squeezes the elastic sheet 31 again. When the socket of the plug-in frame 41 is aligned with the block 32, the elastic sheet 31 drives the block 32 to recover and makes the block 32 plug-in to the plug-in frame 41.

[0028] The mounting rod 3 is connected to the mounting seat 4 by a snap-fitting manner, which facilitates the installation and removal of the infrared thermal imager 5 and facilitates timely handling of any impact or damage to parts when used outdoors.

[0029] The implementation principle of a detection device for transformer installation in an embodiment of the present application is as follows: the servo motor 13 can be started, so that the servo motor 13 drives the threaded rod 12 to rotate, the threaded rod 12 drives the moving block 2 to move, and the moving block 2 drives the upper mounting rod 3 to move, so that the mounting rod 3 drives the infrared thermal imager 5 on the mounting seat 4 to move, so that the infrared thermal imager 5 moves laterally and moves to the intersection of the two sides of the transformer, and while moving, the mounting rod 3 drives the fixed frame 6 to move, so that the gear 8 of the fixed frame 6 intermittently engages with the gear plate 91 installed on the mounting plate 9 during the movement. When the gear plate 91 engages with the gear 8, the gear plate 8 rotates and drives the gear ring 7 to rotate, so that the gear ring 7 drives the mounting rod 3 to rotate, and drives the infrared thermal imager 5 to rotate slightly with the center of the mounting rod 3 as the axis. After the infrared thermal imager 5 rotates, it is directed to the side of the transformer, thereby performing infrared thermal imaging detection on the temperature of the side to ensure the accuracy of the value.

[0030] When the transformer is large and it is necessary to detect the temperature at various positions on the longer side, the screw rod 10 can be rotated to drive the mounting plate 9 to move so that the gear plate 91 is separated from the gear 8. At this time, the threaded rod 12 drives the moving block 2 to move, so that when the mounting rod 3 and the mounting seat 4 drive the infrared thermal imager 5 to move, the gear 8 is not affected by the meshing and therefore does not rotate, so that the infrared thermal imager 5 can move laterally and detect the temperature values ​​of various parts of the transformer while moving.
