Technical Field

[0002] The transformer winding deformation tester is a specialized intelligent device for detecting the mechanical condition of power transformer windings. Its core lies in the deep integration of intelligent sensing technology, making the device itself an intelligent sensor with sensing, analysis, and judgment capabilities. It is mainly used to diagnose winding deformation faults caused by short circuits, transportation vibrations, etc. Its working principle is based on frequency response analysis: by injecting signals of different frequencies into the winding, it collects response data and generates frequency response curves. By comparing the differences between the original curve and the standard curve, it can determine whether there is deformation in the winding (such as displacement, bulging, broken strands, etc.). The instrument is easy to operate and is usually equipped with dedicated test leads and software. It can quickly complete data acquisition, analysis, and report generation. It is widely used in the acceptance testing, preventive testing, and fault diagnosis of power system transformers, providing an important basis for the safe operation of transformers.

[0046] 1. This transformer winding deformation tester, through the synergistic effect of airflow mechanism and cooling components, wherein in Example 1, an electric slider drives the airflow, in Example 2, sand particles circulate and absorb heat, and in Example 3, water cooling circulation, a heat exchange channel is established between the ventilation pipe and the test component, directly dissipating the heat generated during the test, significantly reducing the continuous temperature rise in the core test area.

Furthermore, it can determine whether the transformer has been severely damaged and requires major repair based on the measurement results. For operating transformers, regardless of whether past frequency domain characteristic maps are stored, the degree of fault can also be judged by comparing the differences in characteristic maps between the coils of the faulty transformer. The transformer winding deformation tester is a specialized intelligent device for detecting the mechanical condition of power transformer windings. Its core lies in the deep integration of intelligent sensing technology, making the device itself an intelligent sensor with sensing, analysis, and judgment capabilities.

[0066] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0067] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0068] Example 1, please refer to Figure 1-6 13-14, the present invention provides a technical solution: a transformer winding deformation tester, including a storage box 1, and a winding transformer detection mechanism 2 is fixedly connected to the top of the storage box 1;

[0069] Winding transformer testing mechanism 2 includes:

[0070] Transformer testing component 21 is fixedly connected to the top of storage box 1;

[0071] Control switch 22 is fixedly connected to the front of transformer test component 21;

[0073] An airflow mechanism 3 is fixedly connected to the top of the storage box 1, near the winding transformer detection mechanism 2.

[0074] Storage box 1 is set in the required position, and then winding transformer testing mechanism 2 is set on storage box 1. When the transformer experiences inter-turn or inter-phase short circuits during testing, or is impacted during transportation, causing relative displacement of the coils, or when the coils are deformed due to electromagnetic tension under short circuit and fault conditions during operation, the distributed parameters of the transformer windings will change, thereby affecting and changing the original frequency domain characteristics of the transformer, such as changes in frequency response amplitude and resonant frequency shift. Winding transformer testing mechanism 2 can test the transformer windings.

[0075] The winding transformer testing mechanism 2 quantifies the changes in the response parameters of the transformer's internal windings in different frequency domains. Based on the magnitude of these changes, the amplitude, region, and trend of the frequency response changes, it determines the degree of change in the transformer's internal windings. Furthermore, based on the measurement results, it can determine whether the transformer has been severely damaged and whether a major overhaul is necessary. For transformers in operation, regardless of whether past frequency domain characteristic maps are available, the degree of fault can also be determined by comparing the differences in the characteristic maps between the coils of the faulty transformer.

[0076] The winding transformer testing mechanism 2 is equipped with an automatic data analysis system. It performs a transverse comparison of the winding similarity between phases A, B, and C, and the analysis results are as follows:

[0077] Good consistency

[0078] Good consistency

[0079] Poor consistency

[0080] Poor consistency

[0081] A longitudinal comparison of AA, BB, and CC data, comparing the original and current data in phase, reveals the following winding deformation analysis results:

[0082] Normal winding

[0083] Slight deformation

[0084] Moderate deformation

[0085] Severely deformed.

[0086] The outer wall of the transformer test component 21 is provided with mounting holes 5, and a second rubber ring 11 is fixedly connected to both ends of the outer wall of the transformer test component 21 located at the mounting holes 5.

A tortuous tube 31 is fixedly connected to the top of the storage box 39, and an airflow chamber 32 is fixedly connected to the top of the tortuous tube 31. A sleeve pipe 35 is fixedly connected to the outer wall of the airflow chamber 32, and a ventilation pipe 36 is inserted between the sleeve pipe 35 and the storage box 39.

[0088] Both ends of the ventilation pipe 36 are fitted with first rubber rings 37, and both ends of the ventilation pipe 36 are also provided with threads. Nuts 38 are threadedly connected to both ends of the ventilation pipe 36, and the first rubber rings 37 are in contact with their corresponding second rubber rings 11.

[0089] Ventilation duct 36 is inserted into mounting hole 5.

[0090] A collar 33 is fixedly connected to the outer wall of the airflow chamber 32, and a limit rod 34 is fixedly connected to the top of the storage box 39. The collar 33 is sleeved on the outer wall of the limit rod 34.

[0091] The ventilation pipe 36 is inserted into the mounting hole 5 of the transformer test component 21. The storage box 39 is set at the bottom of the mounting hole 5. Then, one end of the ventilation pipe 36 is inserted into the storage box 39. Then, the airflow chamber 32 is installed on the limiting rod 34 through the collar 33, thereby limiting the rotation angle of the airflow chamber 32. The bend pipe 31 is made of elastic material, thereby adapting to the rotation process of the airflow chamber 32 and maintaining the normal passage of airflow. The two ends of the ventilation pipe 36 are provided with a first rubber ring 37, a nut 38 and a thread. Then, rotating the nut 38 will squeeze the first rubber ring 37 and the second rubber ring 11, so that the two fit together and maintain the sealing of the transformer test component 21.

[0092] A cooling component is fixedly connected to the inner wall of storage box 39.

[0093] The cooling component is a cooling mechanism 4, which includes a slide rail 42. The slide rail 42 is fixedly connected to the inner wall of the storage box 39. An electric slider 44 is slidably connected to the outer wall of the slide rail 42. A vertical plate 43 is fixedly connected to the outer wall of the electric slider 44. A ventilation hole 41 is opened on the outer wall of the ventilation pipe 36.

[0094] Ventilation hole 41 is opened on ventilation pipe 36, so the airflow passing through ventilation pipe 36 will enter transformer test component 21, thereby guiding heat to flow. Electric slider 44 is slidably connected on slide rail 42. When the electric slider 44 is powered on, it moves back and forth on slide rail 42. During the movement, it will drive vertical plate 43 to move in storage box 39. Vertical plate 43 is set according to the shape of the inner wall of storage box 39. Then, the size of vertical plate 43 is slightly smaller than the inner wall of storage box 39. When vertical plate 43 moves to one side, it will squeeze the airflow in storage box 39 through ventilation pipe 36 or tortuous pipe 31 and airflow chamber 32 into transformer test component 21. At this time, a small negative pressure will be generated in the opposite direction of vertical plate 43, which will guide the airflow speed in transformer test component 21 and accelerate the heat dissipation of transformer test component 21.

Then, one end of the ventilation pipe 36 is inserted into the storage box 39. The airflow chamber 32 is then installed on the limiting rod 34 through the collar 33, thereby limiting the rotation angle of the airflow chamber 32. The bend pipe 31 is made of elastic material, which adapts to the rotation process of the airflow chamber 32 and keeps the sand passing through normally. The two ends of the ventilation pipe 36 are provided with a first rubber ring 37, a nut 38 and a thread.

The fan 93 drives the elastic wire 94 and the actuating plate 95 to rotate. The rotation of the actuating plate 95 will stir the water in the U-tube 92 to mix with the air, thereby reducing the temperature of the air.
