Description

Technical Field

[0001] This utility model relates to the field of partial discharge monitoring technology, and in particular to a modular combined transformer partial discharge digital monitoring device. Background Technology

[0002] Modular and combined digital partial discharge monitoring equipment for transformers is commonly used in substations, power plants, and other locations to monitor transformers in real time. Its function is to collect partial discharge signals through sensors, process and analyze them, and promptly detect potential faults such as internal insulation defects in the transformer. This enables accurate fault location and early warning, ensuring the safe and stable operation of the transformer and reducing the risk of sudden accidents.

[0003] In practical applications, existing digital monitoring equipment for partial discharge in transformers, using sensors and data acquisition devices in conjunction, can meet the basic requirements for discharge detection, but the following problems still exist:

[0004] When digital monitoring equipment performs partial discharge testing on transformers, the detectors are directly connected to the equipment with wires that are scattered on the ground. This can cause the wires to be pulled by workers as they walk around, leading to loose connections and detachment. Therefore, this application provides a modular combined digital monitoring device for partial discharge of transformers to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a modular combined digital monitoring device for partial discharge of transformers.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a modular combined transformer partial discharge digital monitoring device, comprising a detector body and a connecting wire disposed on the top of the detector body, and further comprising:

[0007] An anti-detachment component includes a fixed base installed on the top of the detector body, a connecting rod provided on the side of the connecting wire, a protrusion fixed on the side of the connecting rod, a sliding groove provided on the inner wall of the fixed base, and a snap-fit ​​groove provided on the top of the sliding groove.

[0008] A support assembly, the support assembly including a sliding plate disposed on the outer surface of the connecting line, the bottom of the sliding plate being fixed to the top of the connecting rod.

[0009] Furthermore, a second support plate is fixed to the bottom of the fixing base, and a first spring is fixed to the top of the second support plate.

[0010] The technical effect of adopting the above technical solution is that by setting the first spring piece, it is possible to fix the engagement between the protrusion and the snap-fit ​​groove.

[0011] Furthermore, a first support plate is fixed to the top of the first spring piece.

[0012] The technical effect of adopting the above technical solution is that by setting the first support plate, the stress generated by contact with the protrusion can be transferred to the first spring sheet.

[0013] Furthermore, a limiting groove is provided on the top of the first support plate.

[0014] The technical effect of adopting the above technical solution is that by opening a limiting groove, the position of the protrusion can be assisted in fixing.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] By setting a connecting rod, the protrusion can be supported. The protrusion, together with the slide and snap-fit ​​groove, provides additional fixation at the connection between the connecting wire and the detector body, ensuring that the connecting wire will not fall off when it is pulled, and ensuring stable operation of the equipment.

[0025] 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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a modular combined transformer partial discharge digital monitoring device, including a detector body 1 and a connecting line 11 disposed on the top of the detector body 1, and further including:

[0027] The anti-detachment component 2 includes a fixed base 21 installed on the top of the detector body 1, a connecting rod 22 provided on the side of the connecting line 11, a protrusion 23 fixed on the side of the connecting rod 22, a sliding groove 27 opened on the inner wall of the fixed base 21, and a snap-fit ​​groove 28 opened on the top of the sliding groove 27.

[0028] Support assembly 3 includes a sliding plate 31 slidably connected to the outer surface of the connecting line 11. The bottom of the sliding plate 31 is fixed to the top of the connecting rod 22. A second support plate 26 is fixed to the bottom of the fixed base 21. A first spring piece 25 is fixed to the top of the second support plate 26. A first support plate 24 is fixed to the top of the first spring piece 25. A limit groove 29 is formed on the top of the first support plate 24. The specific model of the detector body 1 is ZC-202A. By setting the connecting rod 22, support can be provided for the protrusion 23. By manually pushing the connecting line 11 into the inner cavity of the detector body 1, one end of the protrusion 23 can be made to move clockwise along the inner cavity of the sliding groove 27. When the protrusion 23 moves to a certain position, the outer surface of the protrusion 23 and the limit groove 29 are aligned. The inner wall of the groove 29 contacts the first spring 25, which is compressed by the first support plate 24. At this time, the protrusion 23 continues to move, and the first spring 25 releases stress, thereby enabling the protrusion 23 to engage with the inner cavity of the locking groove 28. This achieves the effect of quick connection between the detector body 1 and the connecting line 11, ensuring that the connection between the detector body 1 and the connecting line 11 will not be interrupted due to pulling during use. Similarly, when it is necessary to remove the connecting line 11, the sliding plate 31 is pushed downward, which causes the protrusion 23 to push the first support plate 24 downward. Then, the protrusion 23 is twisted counterclockwise, which causes the protrusion 23 to fall out of the inner cavity of the sliding groove 27, thereby canceling the connection between the detector body 1 and the connecting line 11.

[0029] Furthermore, such as Figure 2 and Figure 4As shown: A second spring piece 32 is fixed to the bottom of the sliding plate 31, and a third support plate 33 is fixed to the bottom of the second spring piece 32. The inner wall of the third support plate 33 is fixed to the outer surface of the connecting line 11. By setting the second spring piece 32, the sliding plate 31 can be reset. By the cooperation of the sliding plate 31 and the second spring piece 32, the connection between the connecting line 11 and the detector body 1 can be easily canceled. By setting the third support plate 33, the second spring piece 32 and the sliding plate 31 can be supported.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] In use: The operator manually pushes the connecting wire 11 into the inner cavity of the detector body 1, which causes the sliding plate 31 to move the protrusion 23 along the inner cavity of the slide groove 27 via the connecting rod 22. When the protrusion 23 moves to a certain position, the bottom of the outer surface of the protrusion 23 contacts the inner wall of the limiting groove 29, which allows the first support plate 24 to push the first spring piece 25 to compress. At this time, the protrusion 23 continues to move, and the first spring piece 25 releases stress, which allows the protrusion 23 to enter the inner cavity of the snap-fit ​​groove 28, thereby completing the quick snap-fit ​​between the detector body 1 and the connecting wire 11. To prevent the connection between the detector body 1 and the connecting wire 11 from being interrupted due to pulling during use, when it is necessary to remove the connecting wire 11, simply hold the side of the connecting wire 11 with one hand and press down on the sliding plate 31 with the other hand. This will cause the second spring 32 to be compressed, which will in turn cause the protrusion 23 to push the first support plate 24 downward. When the protrusion 23 moves to a certain position, rotate the protrusion 23 counterclockwise, which will cause the protrusion 23 to disengage from the inner cavity of the slide groove 27, thereby achieving the effect of removing and fixing the detector body 1 and the connecting wire 11.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
