Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformers, and in particular to a dry-type transformer monitoring device used in electrical engineering. Background Art

[0002] A dry-type transformer is a transformer that does not use liquid cooling and is usually used in power systems. Dry-type transformers are insulated with solid insulating materials (such as epoxy resin) and have good heat resistance and moisture resistance. Dry-type transformers dissipate heat through natural convection or forced air cooling during use and are suitable for use indoors or in well-ventilated environments. When a dry-type transformer is in use, a temperature sensor must be used and attached to the surface of the dry-type transformer to monitor the temperature of the dry-type transformer to prevent the temperature of the dry-type transformer from being too high and to improve the safety of the dry-type transformer during use.

[0003] When the temperature of a dry-type transformer is monitored by a temperature sensor, since the temperature sensor is fixedly arranged, the temperature sensor can only monitor the temperature of a fixed position of the dry-type transformer.

A protective net 24 is fixed to the inner wall of the air outlet hole opened on the top plate 22. An exhaust fan 23 is fixed to the bottom of the top plate 22 and located at the air outlet. A side blocking assembly 25 is provided on the inner wall of the box body 2. The servo motor 21 is electrically connected to the infrared temperature sensor 13. When the infrared temperature sensor 13 detects that the temperature of the transformer body 1 is too high, the top plate 22 is opened by the servo motor 21. After the top plate 22 is opened, the top of the box 2 is open, so that the internal temperature of the box 2 is easier to dissipate. An audible and visual alarm (not shown in the figure) and a reset button (not shown in the figure) are provided on the box 2. When the temperature is too high, the audible and visual alarm will sound an alarm. When the temperature returns to normal, the reset button is used to reset the device. The side blocking assembly 25 includes a fixing seat 26 fixed to the inner wall of the box body 2, a through hole 35 is opened on the side of the box body 2, a round hole 27 is opened on the fixing seat 26, and the round hole 27 is connected to the through hole 35. A plurality of flip plates 28 are rotatably connected to the fixing seat 26 through a rotating shaft, and a connecting rope 29 is fixedly connected to the plurality of flip plates 28. A connecting plate 30 is fixed to the top of the connecting rope 29, and a guide column 32 is movably penetrated through the top of the connecting plate 30. A square plate 31 is fixed to the top and bottom of the guide column 32.

When the temperature of the transformer body 1 is too high, the support rod 9 moves upward to drive the flip plate 28 to flip open. At the same time, the top plate 22 flips and fits the side of the box body 2. The airflow blown inward by the exhaust fan 23 is guided upward through the flip plate 28, and cooperates with the airflow blown upward by the air inlet fan 34 to further make the airflow flow upward. The airflow can take away more heat from the transformer body 1, and the time required for cooling the transformer body 1 is shorter.

[0044] like Figure 8As shown, in this embodiment, a flip assembly 14 is provided on the top of the square tube 5, and the flip assembly 14 includes a round rod 15 fixed to the top of the square tube 5, and the round rod 15 is arranged parallel to the screw 7. A connecting piece 16 is fixed on the surface of the round rod 15, and a rubber plate 17 is fixed on the connecting piece 16. A round plate 18 is fixedly sleeved on the surface of the support rod 9. When the infrared temperature sensor 13 detects that the temperature of the transformer body 1 is too high, the round rod 15 drives the round plate 18 to fit on the rubber plate 17. Through the friction between the round plate 18 and the rubber plate 17, the round plate 18 drives the round rod 15 to rotate, and the round rod 15 drives the V-shaped piece 10 to rotate, so that the V-shaped piece 10 is separated from the transformer body 1. When the temperature of the transformer body 1 is too high, the inner screw The grooved sleeve 8 drives the lever 33 to move upward, and the lever 33 drives the flip plate 28 to flip upward through the connecting plate 30 and the pull rope. When the temperature of the transformer body 1 is too high, the support rod 9 will exceed the coil part of the transformer body 1 and continue to move upward. The circular plate 18 rotates on the rubber plate 17 to rotate the support rod 9. The support rod 9 drives the V-shaped member 10 to rotate, and the V-shaped member 10 drives the infrared temperature sensor 13 to flip. The infrared temperature sensor 13 is away from the transformer body 1, and the infrared temperature sensor 13 is out of the high temperature area, which can protect the infrared temperature sensor 13. In addition, the V-shaped member 10 can pour out the dust generated by the brush 12 during rotation, so as to clean the inside of the V-shaped member 10.

[0045] like Fig.12 and Fig.13 As shown, in this embodiment, the surface of the rubber plate 17 is provided with anti-slip stripes, and the bottom of the rubber plate 17 is provided with a guide surface, which guides the circular plate 18 so that the circular plate 18 can be easily fitted with the rubber plate 17.

[0046] like Figure 8 , Fig.10 and Fig.11 As shown, in this embodiment, a plurality of V-shaped members 10 are fixed on the circumferential surface of the support rod 9, a triangular plate 11 is fixed on the inner wall of the plurality of V-shaped members 10, an infrared temperature sensor 13 is fixed on the side of the triangular plate 11 close to the transformer body 1, a brush 12 is fixed on the side of the plurality of V-shaped members 10 close to the transformer body 1, the brush 12 is attached to the surface of the transformer body 1, when the infrared temperature sensor monitors the temperature of the transformer body 1, the bottom of the V-shaped member 10 guides the airflow of the air inlet fan 34 to prevent the airflow from entering between the infrared temperature sensor 13 and the transformer body 1, and when the V-shaped member 10 moves up and down, the V-shaped member 10 drives the brush 12 to move up and down, and the brush 12 cleans the surface of the transformer body 1, the brush 12 is made of high temperature resistant material, and the brush 12 is dense, so it is difficult for gas to pass through between the brushes 12.

[0047] like Figure 8 As shown, in this embodiment, the intervals between the multiple V-shaped members 10 are the same, and the number of the multiple V-shaped members 10 corresponds to the number of coils of the transformer body 1 .

[0048] like Figure 8 As shown, in this embodiment, the bottoms of the multiple V-shaped members 10 are provided with chamfers to prevent the bottoms of the V-shaped members 10 from being too sharp and to prevent them from affecting the staff.

[0049] like Figure 4 As shown, in this embodiment, the flip plate 28 flips upward at an angle greater than ninety degrees. The flip plate 28 guides the airflow entering from the side of the box 2, causing the airflow to flow upward at an angle and merge with the vertical airflow, making it easier for the airflow to blow upward, thereby accelerating the cooling of the inside of the box 2.

[0050] like Figure 3 As shown, in this embodiment, a slope is provided on one side of the fixing seat 26 close to the transformer body 1 , and the flip plate 28 can fit on the slope, so that the flip plate 28 can be more easily pulled upward by the connecting rope 29 .

[0051] like Figure 8 As shown, in this embodiment, the support rod 9 is horizontally arranged, and the support rod 9 and the screw rod 7 are vertically arranged, so that the support rod 9 is more stable in the up and down reciprocating movement, and the support rod 9 is prevented from tilting.

[0052] Working principle: when the transformer body 1 is in use, the servo motor 6 in the square tube 5 drives the screw 7 to rotate forward, the screw 7 drives the internal threaded sleeve 8 to move upward, the internal threaded sleeve 8 drives the support rod 9 to move upward, the support rod 9 drives the V-shaped piece 10 to move upward, the V-shaped piece 10 drives the infrared temperature sensor 13 to move upward, and the infrared temperature sensor 13 is used to detect the coil position of the transformer body 1. The process of the V-shaped piece 10 moving upward can also drive the brush 12 to move on the coil of the transformer body 1. The transformer body 1 is cleaned by the brush 12, so that the temperature detection of the infrared temperature sensor 13 is more accurate. When the temperature of the transformer body 1 is at a normal value, the infrared temperature sensor 13 moves to the position close to the top of the coil of the transformer body 1, and the servo motor 6 is reversed, and the servo motor 6 drives the screw 7 to reverse, so that the infrared temperature sensor 13 moves downward. Through the forward and reverse rotation of the servo motor 6, the infrared temperature sensor 13 is driven to move up and down to detect multiple positions of the transformer body 1.

[0053] When the infrared temperature sensor 13 detects that the temperature of the transformer body 1 exceeds the threshold value, the infrared temperature sensor 13 detects the temperature and sends a signal to the information processing unit. The information processing unit issues a command to control the servo motor 21 on the rotating seat 20 to start, and the servo motor 21 drives the top plate 22 to rotate to the side of the box body 2. The top of the box body 2 is now open. At the same time, the servo motor 16 rotates forward, and the servo motor 16 drives the screw 7 to rotate, so that the support rod 9 continues to move upward. The support rod 9 will exceed the coil part of the transformer body 1. At this time, the circular plate 18 on the surface of the support rod 9 contacts the rubber plate 17, and the friction between the circular plate 18 and the rubber plate 17 drives the circular plate 18 to rotate. The rotation of the circular plate 18 drives the support rod 9 to rotate, and the support rod 9 drives the V-shaped piece 10 to rotate. The V-shaped piece 10 drives the infrared temperature sensor 13 to rotate, and the infrared temperature After the temperature sensor 13 is separated from the surface of the transformer body 1, the infrared temperature sensor 13 can be protected, and after the V-shaped member 10 is flipped, the dust inside the V-shaped member 10 will fall out and be blown upward by the airflow, and while the support rod 9 moves upward, the internal threaded sleeve 8 also drives the lever 33 to move upward, and the lever 33 will contact the bottom of the connecting plate 30, and the lever 33 drives the connecting plate 30 to move upward, and the connecting plate 30 will drive the connecting rope 29 to pull upward, and the connecting rope 29 drives the flip plate 28 on the fixing seat 26 to rotate upward, at this time, the airflow of the exhaust fan 23 enters the box body 2 from the through hole 35 and the circular hole 27, and the airflow is blown upward by the flip plate 28 flipped upward, and the inclined airflow intersects with the vertical upward airflow generated by the air inlet fan 34, so that the airflow is easier to blow out from the top of the box body 2, thereby promoting the cooling of the inside of the box body 2;

[0054] At the same time, the sound and light alarm sounds an alarm, and personnel come to check. When the temperature drops, the entire system is reset by pressing the reset button, and the transformer body 1 can be used normally.

[0055] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
