Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer technology, and specifically to a transformer. Background Technology

[0002] In existing technology, oil-immersed transformers use a main oil conservator and an auxiliary oil conservator to store and replenish oil for the transformer and the on-load tap changer. The main oil conservator is a large oil conservator connected to the transformer body, while the auxiliary oil conservator is connected to the on-load tap changer tank. Typically, the auxiliary and main oil conservators are designed together, separated by a partition, and connected to the transformer body and on-load tap changer respectively through different oil outlets. However, the main oil conservator has a large volume and is heavy, therefore its installation position is relatively high. This necessitates additional piping for the auxiliary oil conservator to connect to the on-load tap changer tank, resulting in additional material waste.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a transformer to solve the technical problem that the auxiliary oil conservator in the oil-immersed transformer needs to be connected to the oil-load tap changer through an additional pipeline, resulting in additional material waste.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A transformer is provided, comprising: a main oil conservator support, which is installed on the top plate of the transformer body, and a main oil conservator is mounted on the main oil conservator support, the main oil conservator being connected to the interior of the transformer body; and an auxiliary oil conservator support, which is installed on the top plate of the transformer body at a position corresponding to the installation position of the on-load switch tank, and an auxiliary oil conservator is mounted on the auxiliary oil conservator support, the auxiliary oil conservator being connected to the on-load switch tank; wherein, the installation height of the auxiliary oil conservator is lower than the installation height of the main oil conservator.

[0006] Furthermore, the auxiliary oil conservator support includes: a support base, which is installed on the top plate of the transformer body at the installation position corresponding to the on-load switch tank; and a support body, which includes a support plate and a support column. The support plate is connected to the support base, one end of the support column is connected to the support plate, and the other end of the support column is connected to the auxiliary oil conservator.

[0007] Furthermore, the support base includes a mounting plate, one end of which is connected to the top plate of the transformer body, and the other end of which protrudes from the side wall of the transformer body.

[0008] Furthermore, the transformer includes an oil level gauge, which is mounted on the side wall of the auxiliary oil conservator.

[0009] Furthermore, the transformer includes a rain cover, which is fixedly connected to the side wall of the auxiliary oil conservator. The interior of the rain cover forms a receiving space, which contains an oil level gauge.

[0010] Furthermore, the transformer includes a third connecting flange, which is located on the side wall of the auxiliary oil conservator and is connected to the oil level gauge.

[0011] Furthermore, the transformer includes: a first connecting flange, which is disposed on the auxiliary oil tank; a first connecting pipeline, on which an on-load switch gas relay is installed, one end of the first connecting pipeline being connected to the first connecting flange, and the other end of the first connecting pipeline being connected to the on-load switch tank.

[0012] Furthermore, the transformer includes: a second connecting flange, which is disposed on the auxiliary oil conservator and is spaced apart from the first connecting flange; and a second connecting pipe, one end of which is connected to the second connecting flange and the other end of which is connected to the dehumidifier.

[0013] Furthermore, the auxiliary oil conservator includes a suction pipe located inside the auxiliary oil conservator. The suction end of the suction pipe is connected to the interior of the auxiliary oil conservator, and the output end of the suction pipe is connected to the second connecting flange.

[0014] Beneficial effects:

[0015] In the transformer of this embodiment, the auxiliary oil conservator is separated from the main oil conservator. By setting an auxiliary oil conservator bracket, the auxiliary oil conservator is installed closer to the on-load tap changer tank. This not only reduces the installation height of the auxiliary oil conservator but also reduces the distance between the auxiliary oil conservator and the on-load tap changer tank, thus reducing the oil transport stroke. This allows for the use of shorter connecting pipelines, avoiding additional material waste and simplifying the overall structure. This significantly reduces material consumption and installation costs, solving the technical problem in related technologies where the auxiliary oil conservator in an oil-immersed transformer requires additional pipelines to connect to the oil-load tap changer, resulting in additional material waste.

[0025] 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.

[0026] According to an embodiment of this utility model, a transformer is provided; please refer to [link / reference]. Figures 1 to 6 The system includes: a main oil conservator bracket, which is installed on the top plate of the transformer body 10, and a main oil conservator 30 is installed on the main oil conservator bracket, which is connected to the interior of the transformer body 10; and an auxiliary oil conservator bracket 1, which is installed on the top plate of the transformer body 10 at the installation position corresponding to the on-load switch tank 20, and an auxiliary oil conservator 2 is installed on the auxiliary oil conservator bracket 1, which is connected to the on-load switch tank 20; wherein, the installation height of the auxiliary oil conservator 2 is lower than the installation height of the main oil conservator.

[0027] In this way, by separating the auxiliary oil conservator 2 from the main oil conservator 30 and setting the auxiliary oil conservator bracket 1, the auxiliary oil conservator is installed closer to the on-load tap changer tank 20. This not only reduces the installation height of the auxiliary oil conservator but also reduces the distance between the auxiliary oil conservator and the on-load tap changer tank 20, thus reducing the oil transport stroke. This allows for the use of shorter connecting pipelines, avoids additional material waste, and simplifies the overall structure. This significantly reduces material consumption and installation costs, and solves the technical problem in related technologies where the auxiliary oil conservator in an oil-immersed transformer needs to be connected to the oil-load tap changer via additional pipelines, resulting in additional material waste.

[0028] In the transformer of this embodiment, see Figure 2 The auxiliary oil conservator bracket 1 includes: a support base 11, which is installed on the top plate of the transformer body 10 at the mounting position corresponding to the on-load switch tank 20; and a bracket body 12, which includes a support plate 121 and a support column 122. The support plate 121 is connected to the support base 11, one end of the support column 122 is connected to the support plate 121, and the other end of the support column 122 is connected to the auxiliary oil conservator 2. Thus, the bracket body 12 can be used to support the auxiliary oil conservator 2, and the support base 11 can be used to fix the bracket body 12 and the auxiliary oil conservator 2 onto the transformer body 10.

[0029] In the transformer of this embodiment, see Figure 2 The support base 11 includes a mounting plate 111. One end of the mounting plate 111 is connected to the top plate of the transformer body 10, and the other end of the mounting plate 111 protrudes from the side wall of the transformer body 10. By having the other end of the mounting plate protrude from the side wall of the transformer body 10, i.e., suspending the mounting plate in the air, excessive space is avoided on the transformer top plate, preventing an increase in the top plate area and transformer size due to the additional installation of an auxiliary oil conservator, thus further reducing the manufacturing cost of the transformer.

[0030] It should be noted that the mounting plate and the support plate 121 are connected by threads.

[0031] In some embodiments, the mounting plate is made of circular material, and the support plate 121 is also made of circular material. Since the mounting plate is suspended on the outer surface of the transformer body 10, the use of circular material can minimize the area of ​​the support base 11, making the transformer look more aesthetically pleasing, and also prevent the mounting plate or support plate 121 from being too sharp, thus reducing accidental damage or collisions during transportation.

[0032] Understandably, since the volume of the auxiliary oil conservator is smaller than that of the main oil conservator, a structure in which the mounting plate is suspended can be adopted.

[0033] In the transformer of this embodiment, see Figure 2The transformer includes an oil level gauge 3, which is mounted on the side wall of the auxiliary oil conservator 2. The oil level gauge 3 is used to detect the remaining oil level inside the auxiliary oil conservator 2.

[0034] In the transformer of this embodiment, see Figure 2 The transformer includes a rain cover 4, which is fixedly connected to the side wall of the auxiliary oil conservator 2. The interior of the rain cover 4 forms a receiving space, which houses the oil level gauge 3. By setting up the rain cover 4, the oil level gauge 3 is protected from rain, preventing water from affecting its normal operation.

[0035] In the transformer of this embodiment, see Figure 2 The transformer includes a third connecting flange 9, which is located on the side wall of the auxiliary oil conservator 2 and is connected to the oil level gauge 3. By setting the third connecting flange 9, the detection component of the oil level gauge 3 can be located inside the auxiliary oil conservator 2, increasing the sealing performance of the auxiliary oil conservator 2 and reducing the possibility of oil leakage.

[0036] In the transformer of this embodiment, see Figure 2 The transformer includes: a first connecting flange 5, which is mounted on the auxiliary oil conservator 2; a first connecting pipe 51, on which an on-load tap gas relay 6 is installed; one end of the first connecting pipe 51 is connected to the first connecting flange 5, and the other end of the first connecting pipe 51 is connected to the on-load tap tank 20. By setting the first connecting flange 5, the sealing performance of the auxiliary oil conservator is increased, reducing the possibility of oil leakage. By setting the on-load tap gas relay 6, the content of harmful gases such as methane in the oil is detected, and when the harmful gas content exceeds the standard, a signal or tripping circuit is promptly activated, thereby protecting the transformer.

[0037] In the transformer of this embodiment, see Figure 2 The transformer includes: a second connecting flange 7, which is disposed on the auxiliary oil conservator 2 and spaced apart from the first connecting flange 5; and a second connecting pipe 71, one end of which is connected to the second connecting flange 7, and the other end of which is connected to a dehumidifier 8. By providing the second connecting flange 7, the sealing performance of the auxiliary oil conservator is increased, reducing the possibility of oil leakage. Furthermore, the interior of the auxiliary oil conservator 2 is connected to the dehumidifier 8, thereby removing excess moisture from the air in the auxiliary oil conservator 2, reducing the internal humidity of the transformer, and protecting the transformer.

[0038] In the transformer of this embodiment, see Figure 5 The auxiliary oil conservator 2 includes a suction pipe 72, which is located inside the auxiliary oil conservator 2. The suction end of the suction pipe 72 is connected to the inside of the auxiliary oil conservator 2, and the output end of the suction pipe 72 is connected to the second connecting flange 7.

[0039] Specifically, due to its own weight, air generally concentrates in the upper part of the auxiliary oil conservator 2. Therefore, the suction pipe 72 is set up to suck out the air located in the upper part of the auxiliary oil conservator 2, thereby making full use of the dehumidifier 8.

[0040] In some embodiments, the length of the suction line 72 is close to the inner radius of the auxiliary oil conservator 2, thereby ensuring that the air located above the interior of the auxiliary oil conservator 2 is sucked out.
