Description

Technical Field

[0001] This utility model relates to the field of large transformer technology, specifically to a transformer monitoring module and a transformer. Background Technology

[0002] Oil-immersed transformers utilize transformer oil as a cooling medium. By injecting it into the interior and directly contacting the core and windings, combined with an external heat dissipation system, they can efficiently dissipate heat generated during operation. While this design offers excellent heat dissipation, it places extremely high demands on the sealing of the transformer casing. During operation, transformer oil may decompose, producing gases such as oxygen and acetylene, increasing its flammability. Therefore, regular maintenance and testing of the transformer oil are necessary.

[0003] In existing technologies, transformer oil is typically led to the outside to detect key parameters such as the content of harmful gases and temperature. However, the inlet and outlet ports of the detection pipeline are usually located on the transformer body. Due to frequent operation and maintenance, these interfaces are prone to damage, which in turn affects the sealing performance. Once the sealing performance is compromised, the entire transformer body often needs to be replaced, which not only significantly increases maintenance costs but also significantly reduces the maintenance efficiency of the transformer oil monitoring module.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a transformer monitoring module and a transformer to solve the technical problems of high maintenance cost and low maintenance efficiency of transformer monitoring modules in related technologies.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] Example 1

[0029] According to an embodiment of this utility model, a transformer monitoring module is provided. Please refer to [link / reference]. Figures 1 to 3 , Figure 6 The transformer body 10 has an inspection port, and an inspection cover 20 is installed on the inspection port. The transformer monitoring module includes: an oil outlet 1, which is connected to the inside of the transformer body 10; an oil return port 2, which is connected to the inside of the transformer body 10; and a monitoring pipeline 3, which is connected to the oil outlet 1 and the oil return port 2 respectively, and a monitoring device 4 is installed on the monitoring pipeline 3; wherein, the oil outlet 1 and / or the oil return port 2 are located on the inspection cover 20.

[0030] In this way, the oil inlet and outlet ports are moved to the maintenance cover 20. As an independent component, the maintenance cover 20 has significantly lower manufacturing and replacement costs compared to the entire transformer body 10. If the oil inlet and outlet ports are damaged, only the maintenance cover 20 needs to be replaced or repaired, without replacing the entire transformer body, thus greatly reducing maintenance costs. At the same time, the maintenance cover 20 adopts a modular design, which can be quickly disassembled and installed, facilitating the maintenance or replacement of the oil inlet and outlet ports. This modular design simplifies the maintenance process, shortens the maintenance time, and thus significantly improves maintenance efficiency, solving the technical problems of high maintenance costs and low maintenance efficiency of transformer monitoring modules in related technologies.

[0031] In the transformer monitoring module of this embodiment, see... Figure 1 The monitoring pipeline 3 includes an oil tap switch 5, which is installed on the monitoring pipeline 3 and located between the oil outlet 1 and the monitoring device 4. Thus, by setting the oil tap switch 5, the opening and closing of the oil outlet 1 is controlled. When the oil tap switch 5 is opened, the oil outlet 1 opens, and the transformer monitoring module can then perform oil sampling detection.

[0032] It should be noted that the oil intake switch 5 and the oil return switch 6 are, but are not limited to, switches of the type of ball valve, shut-off valve, etc.

[0033] In the transformer monitoring module of this embodiment, see... Figure 1The monitoring pipeline 3 includes a return oil switch 6, which is installed on the monitoring pipeline 3 and located between the monitoring device 4 and the oil outlet 1. In this way, by setting the return oil switch 6, the opening and closing of the return oil outlet 2 is controlled. When the return oil switch 6 is opened, the return oil outlet 2 is opened, and the transformer oil that has been tested returns to the transformer body 10.

[0034] In the transformer monitoring module of this embodiment, see... Figure 1 and Figure 3 The monitoring pipeline 3 includes: an oil outlet pipeline 31, the inlet of which is connected to an oil outlet 1; a main monitoring pipeline 32, which is connected to the oil outlet pipeline 31 via an oil outlet flange 41; and a return oil pipeline 33, the inlet of which is connected to the main monitoring pipeline 32 via a return oil flange 42, and the outlet of which is connected to a return oil outlet 2. Through the design of the monitoring pipeline 3 (including the oil outlet pipeline 31, the main monitoring pipeline 32, and the return oil pipeline), a reasonable pipeline layout is achieved.

[0035] Specifically, the oil outlet line 31 and the oil return line 33 are both welded to the inspection cover 20 to ensure the sealing of the oil outlet 1 and the oil return line 2.

[0036] In the transformer monitoring module of this embodiment, see... Figure 1 and Figure 3 The oil outlet flange 41 includes a first flange and a second flange connected together. The end of the first flange away from the second flange is connected to the oil outlet pipeline 31, and the end of the second flange away from the first flange is connected to the monitoring main pipeline 32. A sealing ring is provided between the first flange and the second flange. The oil return flange 42 also includes a first flange and a second flange connected together. The end of the first flange away from the second flange is connected to the oil return pipeline 33, and the end of the second flange away from the first flange is connected to the monitoring main pipeline 32. A sealing ring is provided between the first flange and the second flange. These features ensure the sealing performance of either the oil outlet flange 41 or the oil return flange 42, improving the sealing effect of the monitoring pipeline.

[0037] In the transformer monitoring module of this embodiment, see... Figure 2 Oil outlet 1 is located at one end of the inspection cover 20, and oil return outlet 2 is located at the end of the inspection cover 20 away from oil outlet 1. In this way, oil outlet 1 and oil return outlet 2 are kept away from each other, thereby preventing oil outlet 1 from sucking in transformer oil that has just returned to the transformer body 10, which would affect the detection effect.

[0038] Understandably, the oil outlet 1 and the oil return outlet 2 can be diagonally distributed on the inspection cover 20 to achieve a greater distance.

[0039] Example 2

[0040] In the transformer monitoring module of this embodiment, see... Figure 4 and Figure 5 The transformer monitoring module includes an oil outlet flange 41, which comprises: an oil outlet flange seat 411, the oil inlet end of which is connected to the oil outlet 1, and the oil outlet flange seat 411 being detachably connected to the maintenance cover 20; and an oil outlet flange plate 412, the side of which is connected to the oil outlet flange seat 411, and the side of which is connected to the monitoring pipeline 3. This direct and detachable connection between the oil outlet flange 41 and the maintenance cover 20 facilitates maintenance and replacement of the oil outlet flange 41, further improving the maintenance efficiency of the transformer monitoring module.

[0041] Specifically, the oil outlet flange seat 411 is fixed to the inspection cover 20 by bolts.

[0042] In the transformer monitoring module of this embodiment, see... Figure 4 and Figure 5 The transformer monitoring module includes an oil return flange 42, which comprises: an oil return flange seat 421, the oil outlet of which is connected to the oil return port 2, and the oil return flange seat 421 being detachably connected to the maintenance cover 20; and an oil return flange plate 422, the side of which is connected to the oil return flange seat 421, and the side of which is connected to the monitoring pipeline 3. This direct and detachable connection between the oil return flange 42 and the maintenance cover 20 facilitates maintenance and replacement of the oil return flange 42, further improving the maintenance efficiency of the transformer monitoring module.

[0043] In the transformer monitoring module of this embodiment, see... Figure 6 The inspection cover 20 has a sealing groove 201, which is corresponding to the oil outlet 1. The sealing groove 201 contains a sealing ring, which abuts against the oil outlet flange seat 411. The inspection cover 20 has a sealing groove 201, which is corresponding to the oil return port 2. The sealing groove 201 contains a sealing ring, which abuts against the oil return flange seat 421.

[0044] The sealing groove on the inspection cover 20, through its interaction with the sealing ring between the oil outlet flange seat 411 or the oil return flange seat 421, enhances the sealing performance of the oil outlet flange 411 or the oil return flange 42. Even if the oil inlet and outlet ports require frequent operation, a good sealing effect can be maintained by replacing the sealing ring or adjusting the sealing structure, thus avoiding transformer oil leakage and avoiding additional maintenance due to sealing problems.

[0046] A transformer, comprising the aforementioned transformer monitoring module.

[0047] Applying the transformer monitoring module in this embodiment to a transformer, the inlet and outlet ports of the transformer oil detection module are moved to the maintenance cover 20. As an independent component, the maintenance cover 20 has significantly lower manufacturing and replacement costs compared to the entire transformer body 10. If the inlet and outlet ports are damaged, only the maintenance cover 20 needs to be replaced or repaired, without replacing the entire transformer body, thus greatly reducing the transformer maintenance cost. At the same time, the maintenance cover 20 adopts a modular design, which can be quickly disassembled and installed, facilitating the maintenance or replacement of the inlet and outlet ports. This modular design simplifies the maintenance process and shortens the maintenance time, thereby significantly improving the transformer maintenance efficiency and solving the technical problems of high maintenance cost and low maintenance efficiency of transformer monitoring modules in related technologies.
