Description

Technical Field

[0001] The present application relates to the technical field of transformer testing, and in particular to a testing device for a transformer. Background Art

[0002] In the field of transformer corrosion resistance testing, the spray test is a commonly used test method. This method simulates the corrosion conditions in the actual working environment and sprays the transformer surface with reagents to evaluate its corrosion resistance. However, in actual operation, the fluidity and uniformity of the spray reagent have an important impact on the experimental results.

[0003] In the spraying experiment, in order to more comprehensively simulate the actual use environment of the transformer, acidic and alkaline solutions are selected as the spraying liquid.

[0004] At present, the spray reagent is often stored in the container during the test, and the spray reagent that is not circulated for a long time is prone to precipitation, resulting in uneven distribution of components in the solution. This unevenness not only affects the effect of the spray test, but also has a negative impact on the accuracy and reliability of the experimental data.

[0005] Specifically, the formation of precipitates will change the chemical composition and concentration of the spray reagents, making the reagents that actually act on the transformer surface inconsistent with expectations. In addition, the inhomogeneity of the solution will also lead to uneven coverage of the reagents on the transformer surface during the spraying process, making it impossible to accurately evaluate the corrosion resistance of the transformer.

[0006] In view of the above problems, a testing device for transformer is now designed. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a testing device for a transformer, which can solve the problem in the related art that a spray reagent that has not circulated for a long time is prone to precipitation, resulting in uneven distribution of components in the solution and affecting the effect of the spray test.

[0027] See also Figure 1-Figure 3 A transformer testing device comprises: a bracket 1 and a test table 3 for placing transformer components; a testing mechanism 2 is arranged on the bracket 1, which comprises a spraying part 21, a storage part 22 and a conveying part 23, the storage part 22 is used to contain spray liquid, the conveying part 23 is used to convey the spray liquid, and the spraying part 21 is used to spray the transformer components; the conveying part 23 comprises a first conveying end 231 and a second conveying end 232, the first conveying end 231 is connected to the spraying part 21, and is used to convey the spray liquid into the spraying part 21, and the second conveying end 232 is connected to the storage part 22, and is used for the circulation of the spray liquid.

[0028] Specifically, the testing mechanism 2 is supported by the bracket 1, wherein the storage portion 22 is used to contain the spray liquid, and the conveying portion 23 is responsible for conveying the spray liquid. Since the conveying portion 23 is designed with a first conveying end 231 and a second conveying end 232, in actual operation, the spray liquid inside the storage portion 22 is extracted through the conveying portion 23, and the spray liquid is delivered to the spray portion 21 through the first conveying end 231. The transformer is sprayed through the spray portion 21 to complete the corrosion resistance test of the transformer, and part of the spray liquid is delivered to the interior of the storage portion 22 through the second conveying end 232, thereby realizing the circulation of the spray liquid. The circulation of the spray liquid can effectively prevent the excessive accumulation of solutes in a specific area, thereby avoiding precipitation caused by uneven concentration, so that the solute molecules or ions can be more evenly distributed in the solution.

[0029] Therefore, through this double-end structure, the continuous circulation of the spray liquid during the test is ensured, the precipitation problem caused by long-term standing is avoided, and at the same time the uniformity of the solution composition is maintained, thereby improving the accuracy of the test results.

[0030] It can be understood that the spray liquid in this embodiment is an acidic or alkaline solution.

[0031] Specifically, Figure 1 and Figure 3 As shown, the detection platform 3 in this embodiment includes a support base 31 and a recovery platform 32 which are interconnected. The support base 31 is located below the spray part 21. A plurality of hollow holes are provided on the support base 31. The recovery platform 32 is hollow inside and has a plurality of water inlet holes formed thereon.

[0032] During the corrosion resistance test of the transformer, the transformer is placed above the support seat 31 and sprayed by the testing mechanism 2. At the same time, the hollow design of the support seat 31 allows the spray liquid to flow smoothly to the recovery platform 32, and then enter the recovery platform 32 through the water inlet hole on the recovery platform 32. The used spray liquid is collected by the recovery platform 32 to achieve resource recycling and avoid environmental pollution by the spray liquid.

[0033] like Figure 4 As shown, the test bench 3 in this embodiment is arranged on the bracket 1, and can also be designed to be separated from the bracket 1 as needed. It only needs to ensure that the test bench 3 is located directly below the spray part 21. The specific installation method is determined according to the transformer model and volume.

[0034] It is understandable that, due to the volume limitation of the recovery table 32 , a pipeline connected to an external recovery container is provided at the bottom of the recovery table 32 , and the solution collected inside the recovery table 32 is transmitted through the pipeline to increase the volume of the recovery table 32 .

[0035] Specifically, the material storage portion 22 in this embodiment is a material storage tank or a material storage box, which is used to contain the spray liquid.

[0036] The material storage portion 22 is used as a storage container for the spray liquid. Its design is simple and practical, and it is convenient to replace and add the spray liquid, thereby ensuring the continuity of the test.

[0037] Specifically, Figure 1 As shown, the spraying part 21 includes a plurality of spray heads 211 , and the plurality of spray heads 211 are distributed along the length direction of the bracket 1 , and the spray heads 211 are connected to an adapter 212 .

[0038] During use, the arrangement of multiple nozzles 211 enables the spray liquid to evenly cover all parts of the transformer assembly, thereby improving the comprehensiveness and accuracy of the test. The design of the adapter 212 facilitates the connection and replacement of the nozzles 211.

[0039] To further explain, Figure 1 and Figure 2 As shown, in this embodiment, the conveying part 23 also includes a pump body 233 and a three-way valve 234, the water inlet of the pump body 233 is connected to the material storage part 22, the water outlet of the pump body 233 is connected to the three-way valve 234, and the other two ends of the three-way valve 234 are respectively connected to the first conveying end 231 and the second conveying end 232.

[0040] The pump body 233 provides power for the spray liquid to ensure that it can flow smoothly. The three-way valve 234 is responsible for controlling the flow direction of the spray liquid. In actual operation, the pump body 233 is turned on, and the pump body 233 extracts the spray liquid inside the storage part 22, and sends the spray liquid to the first conveying end 231 and the second conveying end 232 through the three-way valve 234.

[0041] It should be noted that the three-way valve 234 in this embodiment is a T-shaped three-way valve that can interconnect three orthogonal pipelines and cut off the third channel, thereby playing the role of diversion and confluence.

[0042] Furthermore, the first delivery end 231 in this embodiment includes a first connecting pipe, one end of the first connecting pipe is connected to the three-way valve 234, and the other end of the first connecting pipe is connected to the adapter 212;

[0043] The second delivery end 232 includes a second connecting pipe, and two ends of the second connecting pipe are respectively connected to the three-way valve 234 and the material storage part 22.

[0044] The first connecting pipe and the second connecting pipe are connected to the three-way valve 234 respectively. The first connecting pipe sends the spray liquid into each adapter 212 respectively, and the spraying is completed through the nozzle 211. The spray liquid is sent back to the storage part 22 through the second connecting pipe, so that the spray liquid inside the storage part 22 keeps circulating.
