To ensure the normal operation of oil-immersed transformers, regular oil sampling and monitoring are necessary. This helps to promptly identify potential hazards in the operation of oil-filled electrical equipment and prevent accidents or equipment damage. Oil sampling and monitoring is an important part of the operation and maintenance of oil-immersed transformers and a vital method for monitoring the insulation performance of electrical equipment, ensuring the safe and stable operation of the power system.

[0003] Currently, traditional transformer ball valve-type sampling auxiliary tools cannot quickly adjust the flow rate of insulating oil during use, reducing sampling efficiency. At the same time, they lack a sealing device, which makes it easy for insulating oil to leak during sampling. Utility Model Content

[0004] The purpose of this utility model is to provide a transformer ball valve type sampling auxiliary tool to solve the problems mentioned in the background art, such as the inability to quickly adjust the flow rate of insulating oil during use, which reduces the sampling efficiency, and the lack of a sealing device, which leads to the easy occurrence of insulating oil leakage during sampling.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a transformer ball valve type sampling auxiliary tool, including an internal thread conversion connector 1, a sealing check valve 2 on one side of the internal thread conversion connector 1, a connecting seat 3 on the other side of the sealing check valve 2, a sealing mechanism 4 detachably connected to one side of the connecting seat 3, a mounting seat 5 welded to the upper end of the sealing check valve 2, an adjusting mechanism 6 rotatably connected to the inner wall of the mounting seat 5, a ball valve wrench 7 detachably connected to the upper end of the adjusting mechanism 6, and a hexagonal block 41, one side of the hexagonal block 41 detachably connected to one side of the connecting seat 3, and a threaded portion 42 on one side of the hexagonal block 41. A pagoda-shaped connector 43 is provided on the other side of the corner block 41. A groove 44 is provided on the outer wall of the pagoda-shaped connector 43. A sampling port 45 is provided on the inner wall of the pagoda-shaped connector 43. A hexagonal dustproof nut 46 is threadedly connected to the inner wall of the sampling port 45. One side of the hexagonal block 41 is fixedly connected to one side of the threaded part 42. The other side of the hexagonal block 41 is fixedly connected to one side of the pagoda-shaped connector 43. A threaded groove that matches the outer wall of the hexagonal dustproof nut 46 is provided on the inner wall of the sampling port 45. One side of the sealing check valve 2 is threadedly connected to one side of the internal thread conversion connector 1. One side of the connecting seat 3 is threadedly connected to one side of the sealing check valve 2.

[0023] The operator places the ball valve wrench 7 onto the rotating rod 61, and then fixes the ball valve wrench 7 onto the connecting seat 3 by rotating the nut 63. During use, when it is necessary to sample the transformer oil, the operator can rotate the ball valve wrench 7 to drive the adjusting mechanism 6 to rotate. The rotating rod 61 rotates, so that the ball 66 in the adjusting mechanism 6 can rotate stably under the action of the support ring 68, thereby adjusting the relative position between the through hole 67 and the sealing check valve 2, thus realizing the rapid adjustment of the insulating oil flow and improving the sampling efficiency. The sealing ring 64 ensures that the insulating oil will not leak in the sealing check valve 2. At the same time, the pagoda-shaped connector 43 in the sealing mechanism 4 and the sampling port 45, as well as the threaded connection of the internal hexagonal external thread dustproof nut 46, can effectively ensure the sealing during the sampling process and avoid the leakage of insulating oil. In addition, the internal thread conversion connector 1 facilitates the connection with the transformer oil valve, further improving the convenience of sampling.

[0024] Please see Figure 1 , Figure 3 and Figure 4The adjusting mechanism 6 includes a rotating rod 61, the outer wall of which is rotatably connected to the inner wall of the mounting base 5. A washer 62 is provided on the outer wall of the rotating rod 61. A nut 63 is provided at the upper end of the rotating rod 61. A sealing ring 64 is fixedly connected to the outer wall of the rotating rod 61. A limit ring 65 is sleeved on the bottom of the rotating rod 61. A ball 66 is snapped into the lower end of the rotating rod 61. A through hole 67 is opened through the middle of the ball 66. Support rings 68 are movably connected to both sides of the ball 66. The outer wall of the rotating rod 61 is sleeved with the inner wall of the washer 62. The upper end of the rotating rod 61 is threadedly connected to the inner wall of the nut 63. The lower end of the rotating rod 61 passes through the mounting base 5 and extends into the sealing check valve 2.

[0025] In use, the internal thread adapter 1 is connected to the sampling port 45 on the transformer. Then, the ball valve wrench 7 is rotated to drive the adjustment mechanism 6. The ball 66 in the adjustment mechanism 6 rotates under the action of the support ring 68. The flow rate of insulating oil is controlled through the through hole 67 on the ball 66, so as to quickly adjust the sampling flow rate and improve the sampling efficiency. At the same time, the pagoda-shaped connector 43 in the sealing mechanism 4 is connected to the sampling port 45 on the transformer and fixed by the internal hexagonal external thread dustproof nut 46 to ensure the sealing during sampling, avoid the leakage of insulating oil, and improve the sampling accuracy and safety. In addition, the groove 44 opened on the outer wall of the pagoda-shaped connector 43 facilitates the fixing and disassembly during sampling, which improves the work efficiency.

[0026] Working principle: First, the operator places the ball valve wrench 7 onto the rotating rod 61, and then fixes the ball valve wrench 7 onto the connecting seat 3 by rotating the nut 63. During use, when it is necessary to sample the transformer oil, the operator can rotate the ball valve wrench 7 to drive the adjusting mechanism 6 to rotate. The rotating rod 61 rotates, so that the ball 66 in the adjusting mechanism 6 can rotate stably under the action of the support ring 68, thereby adjusting the relative position between the through hole 67 and the sealing check valve 2, thus realizing the rapid adjustment of the insulating oil flow and improving the sampling efficiency. The sealing ring 64 ensures that the insulating oil will not leak in the sealing check valve 2. At the same time, the pagoda-shaped connector 43 in the sealing mechanism 4 and the sampling port 45, as well as the threaded connection of the internal hexagonal external thread dustproof nut 46, can effectively ensure the sealing during the sampling process and avoid leakage of insulating oil. In addition, the internal thread conversion connector 1 facilitates the connection with the transformer oil valve and further improves the convenience of sampling.

[0027] Then, during use, the device is connected to the sampling port 45 on the transformer via the internal thread adapter 1. The adjusting mechanism 6 is then activated by rotating the ball valve wrench 7. The ball 66 in the adjusting mechanism 6 rotates under the action of the support ring 68. The flow rate of the insulating oil is controlled through the through hole 67 on the ball 66, achieving rapid adjustment of the sampling flow rate and improving sampling efficiency. Simultaneously, the pagoda-shaped connector 43 in the sealing mechanism 4 is connected to the sampling port 45 on the transformer and fixed with an internal hexagonal external thread dustproof nut 46, ensuring sealing during sampling and preventing insulating oil leakage, thus improving sampling accuracy and safety. Furthermore, the groove 44 on the outer wall of the pagoda-shaped connector 43 facilitates fixing and disassembly during sampling, improving work efficiency. This is the entire working process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.
