It is widely used in the fields of equipment inspection and maintenance, quality control and research and development of power equipment. With the increasing complexity of power equipment and the increasing requirements for the reliability of power equipment, traditional transformer testing methods can no longer meet the needs of accuracy, efficiency and convenience in daily testing. Therefore, it is particularly important to develop a high-precision, comprehensive transformer tester.
[0003] Traditional high-precision comprehensive transformer testers mainly consist of a main unit, test input ports, measurement modules, control panels, and data output units. Their working principle includes signal generation and input, signal testing and acquisition, data processing and calculation, result display and analysis, as well as automated testing and result storage. The tester is used to measure various performance characteristics of transformers, such as impedance, no-load, load, and insulation, to ensure their stability and safety.
[0004] Traditional high-precision comprehensive transformer testers are susceptible to collisions and vibrations during transportation, storage, and use, which can damage or cause malfunctions to the internal components. To address these issues, a new high-precision comprehensive transformer tester is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a high-precision comprehensive transformer tester, including a tester 1. Multiple fixed seats 2 are fixedly connected to the outer wall of the tester 1. These fixed seats 2 provide support for the stability of subsequent components. Through the function of these fixed seats 2, the various parts of the instrument can be firmly fixed, avoiding loosening or instability during operation. A damper 7 is fixedly connected to one side of each of the multiple fixed seats 2. The function of the damper 7 is to absorb external vibrations and impacts, reducing their interference with the tester. Especially during high-precision testing, vibration can affect the test results. A spring 8 is sleeved on the outer wall of the damper 7. The spring 8 enhances the elasticity and buffering function of the damper 7, further improving the instrument's shock resistance. It can also push subsequent components to reset. A fixed seat 6 is fixedly connected to one end of the damper 7, ensuring the stable fixation of the damper 7.
[0032] Through the structure of the fixed base 26, the damper 7 can work stably under external force and will not lose its function due to position movement. Three connecting blocks 15 are fixedly connected to the outer wall of the fixed base 26. The connecting blocks 15 are used to connect with subsequent components to ensure the structural integrity between the components and provide a basis for the stable operation of the testing instrument. The inner walls of the three connecting blocks 15 are rotatably connected to rotating rods 24. The rotating rods 24 provide flexibility through rotational connection. One end of the rotating rods 24 is hinged to a rotating rod 13. The rotating rod 13 further improves the range of motion of the rotating rods 24 through hinge, and at the same time can prevent the buffer device from shifting during external impact. A connecting plate 9 is fixedly connected to one side of the fixed base 26. The connecting plate 9 plays the role of connecting different components and ensuring the stable connection of each component. A protective shell 10 is fixedly connected to the outer wall of the connecting plate 9. The protective shell 10 provides external protection for the entire testing instrument and avoids damage to the equipment caused by external collisions, dust, liquids, etc., thereby enhancing the durability and reliability of the instrument. A dustproof component is provided on the top of the testing instrument 1.
[0033] Reference Figure 1 , Figure 3 and Figure 5 The dustproof component includes multiple interfaces 11, which provide various detection capabilities for external connections of the instrument, support effective connection with external devices, and broaden the application range of the tester. Each of the multiple interfaces 11 has a fixed block 12 fixedly connected to its outer wall. The fixed block 12 can provide installation space for subsequent components. The top of the fixed block 12 is fixedly connected to a support block 13, which provides additional support for subsequent connections and enhances the overall structural rigidity. Limiting blocks 14 are rotatably connected to both sides of the support block 13. The limiting blocks 14 can limit the movement range of subsequent components. One end of the limiting block 14 is fixedly connected to a cover 15, which provides additional protection for the dustproof component, prevents external substances from entering, and avoids partial exposure of the interfaces 11, reducing interference from external factors.
[0034] A blocking block 16 is fixedly connected to one side of the cover 15. The blocking block 16 further enhances the protective effect, preventing dust, debris, etc. from entering the instrument and ensuring the long-term stable operation of the instrument. A micro printer 17 is set on the top of the detector 1. The micro printer 17 provides a real-time printing function, allowing users to directly print test results or data reports, increasing the convenience and flexibility of operation. A display 18 is set on the top of the detector 1. The display 18 provides real-time data display for operators, facilitating the observation and adjustment of various parameters during the test process and improving work efficiency. A protective cover 20 is rotatably connected to the top of the protective shell 10. The protective cover 20 is designed to be easy to open and close through a rotatable connection. A data connection port 19 is set on the top of the detector 1. The data connection port 19 provides an installation port for connecting external devices, supporting data transmission and communication, so that test results can be easily saved and analyzed.
[0035] Working principle: When the equipment is subjected to an external impact, the impact force is transmitted to the internal connecting plate 9 through the protective shell 10. The connecting plate 9 then transmits the impact force to the fixed seat 2 6. The fixed seat 2 6 can transmit the impact force to the damper 7 and spring 8. The damper 7 and spring 8 can absorb the impact force. At the same time, the fixed seat 2 6 drives the connecting block 1 5 to move, which in turn drives the rotating rod 2 4 to rotate. During the rotation of the rotating rod 2 4, the rotating rod 3 can rotate on the fixed seat 2, thereby buffering the impact force transmitted from the outside and effectively protecting the detector 1.
[0036] By lifting the cover 15 upwards, the cover 15 can cause the plug 16 to rotate on the support block 13 via the limiting block 14, thereby removing the plug 16 from the inner wall of the interface 11. At this time, the connector can be inserted into the interior of the interface 11 for testing. After the test is completed, by rotating the cover 15, the plug 16 can be placed back into the inner wall of the interface 11, sealing the interior of the interface 11 and preventing dust from entering the interior of the interface 11, which would affect the testing accuracy of the equipment. The sealing of the interface 11 by the cover 15 and the plug 16 can extend the service life of the equipment.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
