Description

Technical Field

[0001] This utility model relates to the technical field of transformer comprehensive testers, specifically to a transformer comprehensive tester with fault early warning function. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change alternating current (AC) voltage. It mainly consists of an iron core and primary and secondary coils wound around it. When AC current passes through the primary coil, the resulting alternating magnetic field induces a voltage in the secondary coil. The voltage is increased or decreased by adjusting the turns ratio. Its core function is to efficiently transmit electrical energy and adapt to different voltage requirements. It is widely used in power systems, electronic equipment, and industrial fields, and also has additional functions such as isolation circuits and impedance matching.

[0003] The transformer comprehensive tester is an integrated power testing device used to comprehensively evaluate key parameters of transformers such as turns ratio, DC resistance, no-load / load loss, and winding deformation. It features high-precision measurement, intelligent calibration, and data storage functions, supports testing of various transformer types, and is widely used in factory quality inspection, power supervision, and fault diagnosis, significantly improving testing efficiency and accuracy.

[0004] The main manifestations of transformer failure include abnormal vibration and abnormal temperature. The existing integrated testing instrument can only perform routine performance tests and does not have the function of monitoring and early warning. If the above abnormalities occur during the simulated operation of the transformer, and the user fails to detect these abnormalities in time when performing routine performance tests one by one, it is very easy to cause equipment damage.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a transformer comprehensive tester with fault early warning function, comprising:

[0026] The base 1 has the transformer integrated tester body 11 fixedly installed on its top;

[0027] Support mechanism 2 is located on top of base 1 and is used to support the transformer under test.

[0028] Fault warning mechanism 3 is installed on top of support mechanism 2. Fault warning mechanism 3 is used to monitor and warn of transformer faults.

[0029] The fault warning mechanism 3 includes a cover frame 31. A warning light 32 is fixedly installed at the corner of the top of the cover frame 31. A vibration sensor 33 is fixedly installed on the outer wall of the cover frame 31. A connecting cover 34 is fixedly connected to the side of the cover frame 31. A through pipe 35 is fixedly connected to the end of the connecting cover 34 away from the cover frame 31. An axial flow fan 36 is fixedly connected to the end of the through pipe 35 away from the connecting cover 34. A temperature sensor 356 and a smoke sensor 357 are installed in the inner cavity of the through pipe 35. The vibration sensor 33, temperature sensor 356, and smoke sensor 357 are all electrically connected to the warning light 32 through a controller. When the transformer vibrates abnormally, the vibration is transmitted to the cover frame 31 through the support mechanism 2 and is detected by the vibration sensor 33. Then, the controller turns on the warning light 32 and controls the axial flow fan 36 to work. The fan can absorb the air near the transformer inside the cover frame 31 through the through pipe 35 and the connecting cover 34. If the temperature of the transformer is abnormal, the temperature of the air will increase abnormally, which can be detected by the temperature sensor 356. Then, the controller can control the air to work. The device activates warning light 32. If smoke appears in the transformer, the smoke sensor 357 can detect it and then activate warning light 32 via the controller, thus realizing the function of early warning of fault manifestation, which facilitates timely maintenance by staff. It is worth noting that the controller, vibration sensor 33, temperature sensor 356, and smoke sensor 357 in this solution are commercially available devices that can be purchased by those skilled in the art. The devices have not been structurally modified in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate on them. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electrical control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0030] As one implementation method in this embodiment, such as Figure 3 As shown, a plate groove 351 is provided at the top of the tube 35. A magnetic block 352 is fixedly installed on the inner wall of the plate groove 351. A movable plate 353 is movably inserted into the inner cavity of the plate groove 351. The top of the magnetic block 352 is magnetically connected to the bottom of the movable plate 353. A handle 354 is fixedly installed on the top of the movable plate 353. The movable plate 353 is installed on the top of the tube 35 by insertion. After insertion, the magnetic block 352 magnetically fixes the movable plate 353. This design facilitates the user to disassemble and maintain the temperature sensor 356 and the smoke sensor 357 in the inner cavity of the tube 35.

[0031] As one implementation method in this embodiment, such as Figure 3 As shown, a support rod 355 is fixedly installed at the bottom of the movable plate 353. The number of support rods 355 is set to two. The temperature sensor 356 and the smoke sensor 357 are respectively fixedly installed at the bottom of the two support rods 355. Through the design of the support rods 355, the temperature sensor 356 and the smoke sensor 357 can be supported, so that they tend to be in the middle of the inner cavity of the pipe 35, and have full contact with the air, thereby improving the monitoring and early warning effect.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, the support mechanism 2 includes a support leg 21, which is fixedly installed on the top of the base 1. A support plate seat 22 is fixedly installed on the top of the support leg 21, and a cover frame 31 is fixedly installed on the top of the support plate seat 22. Through the design of the support plate seat 22, it can work with the cover frame 31 to partially enclose the transformer, which facilitates the entry of outside air.

[0033] As one implementation method in this embodiment, such as Figure 4 As shown, a track rod 23 is fixedly installed on the inner wall of the support plate base 22, and a sliding seat 24 is slidably connected to the outer wall of the track rod 23. A support bar 25 is fixedly installed on the top of the sliding seat 24, and a movable wheel 26 is rotatably connected to the bottom of the sliding seat 24. The movable wheel 26 is rolledly connected to the top of the base 1. When installing the transformer, the sliding seat 24 is pulled out from the bottom of the cover frame 31, and then the transformer is temporarily installed on the top of the support bar 25. Then, the sliding seat 24 is pushed back to its original position, and the transformer can be monitored.

[0034] As one implementation method in this embodiment, such as Figure 5 As shown, the side of the support plate 22 is threaded with a bolt 221. A limiting pad 222 is movably sleeved on the outer wall of the bolt 221. After the sliding seat 24 is pushed and reset, the limiting pad 222 is rotated so that the limiting pad 222 overlaps with the sliding seat 24 on the side. Then the bolt 221 is tightened to fix the position of the limiting pad 222, thus completing the limiting of the sliding seat 24.

[0035] Working principle: In use, pull the sliding seat 24 out from the bottom of the cover frame 31, then temporarily install the transformer on the top of the support bar 25, and then push the sliding seat 24 back to its original position. Then rotate the limiting pad 222 so that the limiting pad 222 overlaps with the sliding seat 24 on the side. Then tighten the bolt 221 to fix the position of the limiting pad 222, thus completing the limiting of the sliding seat 24. Control the axial flow fan 36 to work, and absorb the air near the transformer inside the cover frame 31 through the pipe 35 and the connecting cover 34. Then, the air can be absorbed by the transformer comprehensive tester body 1. 1. During routine performance testing of the transformer, if the transformer vibrates abnormally, the vibration will be transmitted to the cover frame 31 through the support mechanism 2 and detected by the vibration sensor 33. Then, the warning light 32 will be activated by the controller. If the transformer temperature is abnormal, it will cause the air temperature inside the pipe 35 to increase abnormally. The temperature sensor 356 can detect this and the warning light 32 will be activated by the controller. If smoke appears in the transformer, the smoke sensor 357 can detect it and the warning light 32 will be activated by the controller, thus realizing the function of early warning of fault performance.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
