Technical Field

[0001] This utility model relates to the field of transformer oil storage tank technology, specifically a novel capsule oil storage tank for transformers. Background Technology

[0002] Transformers play a vital role in power systems, and the oil conservator is an important component of the transformer. Located at the top of the transformer tank, its main functions include compensating for volume changes in transformer oil due to temperature variations, ensuring that the transformer oil in the tank is always full, and reducing the contact area between the transformer oil and air to prevent the insulating oil from absorbing moisture and oxidizing, thereby extending the service life of the transformer.

[0003] A related technology (announcement number: CN215868908U) discloses an oil conservator for transformers. The disclosed technical solution has the advantages of simple structure, easy processing, low cost, convenient disassembly and installation, and effective reliability. The protrusion set at the detection port is used to prevent the capsule from expanding and blocking the detection port.

[0004] The above-disclosed technical solutions reveal the following problems: when the oil tank capsule is inside the oil tank, the capsule will move when the oil volume inside the oil tank changes. Therefore, the stability of the capsule is crucial for the oil tank. To address this, we propose a novel capsule oil tank for transformers.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the hydraulic pressure problem within the oil conservator in the prior art, this utility model provides a novel bladder-type oil conservator for transformers, employing a hydraulic bladder adapter frame structure combined with a pressure relief structure to ensure stable oil pressure within the conservator. The specific technical solution is as follows:

[0007] A novel bladder oil conservator for transformers includes an oil conservator, a connecting pipe fixed to the outer wall of the oil conservator, a bladder support frame embedded in the inner cavity of the oil conservator, elastic clips evenly fixed to the top of the outer wall of the bladder support frame facing inward, the bladder support frame sliding longitudinally within the inner cavity of the oil conservator via a telescopic member, a pressure relief port embedded in the top of the outer wall of the oil conservator, a sealing plug embedded in the top of the pressure relief port, and the sealing plug being disposed on the outer wall of the oil conservator via an elastic reset member.

[0008] In the above technical solution, an oil level indicator tube is embedded in the bottom of the outer wall of the oil tank, and a sleeve fixed to the outer wall of the oil level indicator tube is sleeved on the outer wall of the oil tank.

[0009] The elastic reset component includes a support fixed to the top of the outer wall of the oil tank, one end of a linkage U-rod is slidably disposed in the inner cavity of the support, the other end of the linkage U-rod is fixed to the top of the sealing plug, a limiting seat located above the support is sleeved on the outer wall of the linkage U-rod, and an elastic element sleeved on the outer wall of the linkage U-rod is disposed between the limiting seat and the support.

[0010] An elastic plug is fixed to the bottom of the sealing plug, and the elastic plug and the sealing plug form a stepped blockage.

[0011] The telescopic component includes a base fixed to the inner wall of the oil tank, and a sliding rod that penetrates the inner cavity of the base is fixed to the bottom of the outer wall of the capsule support frame.

[0012] The bottom end of the slide rod is fixed with a detachable anti-detachment seat.

[0013] An oil filling port is embedded in the top of the oil tank, and a baffle plate fixed to the oil tank is provided above the oil filling port.

[0014] A connecting frame is fixed to the bottom of the outer wall of the oil storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the novel capsule oil storage tank of the transformer:

[0016] 1. The telescopic mechanism allows the capsule holder to move longitudinally within the oil conservator. When the oil level changes, the capsule moves with the capsule holder, ensuring the capsule remains in contact with the oil surface. This automatically balances the pressure inside and outside the capsule, ensuring the transformer body is always filled with insulating oil.

[0017] Second, pull the elastic clips outwards, then place the capsule inside the multiple elastic clips. Release the clips; the elastic force generated when the clips deform will engage the capsule against the outer wall, making the capsule assembly and disassembly process more convenient. The elastic clips ensure the stability of the capsule's position during movement.

[0018] Third, the pressure relief port is opened and closed by the elastic reset component, thereby venting the oil tank and protecting it.

[0019] Fourth, by utilizing the principle of communicating vessels, the oil inside the oil tank will flow into the oil level indicator tube, and the amount of oil stored in the oil tank can be determined by the oil level height inside the oil level indicator tube. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] The following are specific implementation cases and appendices. Figure 1-3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] A novel capsule oil conservator for transformers includes an oil conservator 1. A connecting pipe 10 is fixedly connected to the outer wall of the oil conservator 1, and the connecting pipe 10 is fixedly embedded in the bottom of the outer wall of the oil conservator 1, connecting to the transformer. A capsule support frame 2 is embedded in the inner cavity of the oil conservator 1. Elastic clips 3 facing inward are evenly fixed to the top of the outer wall of the capsule support frame 2. The capsule support frame 2 has a rectangular frame structure, and arc-shaped elastic clips 3 are evenly fixed to the top of the two long sides of the capsule support frame 2, with the top ends of the arc-shaped elastic clips 3 facing inward.

[0027] Pull the elastic clips 3 outwards, then place the capsule inside the multiple elastic clips 3. Release the elastic clips 3; the elastic force generated when the clips 3 deform will engage them with the outer wall of the capsule, making the capsule assembly and disassembly process more convenient. The elastic clips 3 ensure the stability of the capsule's position during movement.

[0028] The capsule support frame 2 slides longitudinally within the inner cavity of the oil conservator 1 via a telescopic component. This telescopic component causes the capsule support frame 2 to move the capsule longitudinally within the oil conservator 1. When the oil level inside the oil conservator 1 changes, the capsule moves with the capsule support frame 2, ensuring that the capsule is in contact with the oil surface. This automatically balances the pressure on both sides of the capsule, ensuring that the transformer body is always filled with insulating oil.

[0029] A pressure relief port 6 is embedded in the top of the outer wall of the oil tank 1, and a sealing plug 8 is embedded in the top of the pressure relief port 6. The sealing plug 8 is set on the outer wall of the oil tank 1 by an elastic reset member. The pressure relief port 6 is opened and closed by the elastic reset member, thereby venting the oil tank 1 and protecting the oil tank 1.

[0030] An oil level indicator tube 9 is embedded in the bottom of the outer wall of the oil tank 1, and a sleeve 19 fixed to the outer wall of the oil level indicator tube 9 is sleeved on the outer wall of the oil level indicator tube 9. The oil level indicator tube 9 is an L-shaped transparent tube, one end of which is fixedly embedded in the bottom of the outer wall of the oil tank 1, and the other end of which is located longitudinally on one side of the oil tank 1.

[0031] Utilizing the principle of communicating vessels, the oil inside the oil tank 1 flows into the oil level indicator tube 9, allowing the reader to determine the amount of oil stored in the oil tank 1 based on the oil level height inside the indicator tube 9. The sleeve 19 is fixedly fitted onto the outer wall of the oil level indicator tube 9 through longitudinally opened mounting holes, ensuring the stability of the oil level indicator tube 9.

[0032] It is worth noting that the elastic reset component includes a support 7 fixed to the top of the outer wall of the oil tank 1. One end of a linkage U-rod 13 is slidably disposed in the inner cavity of the support 7, and the other end of the linkage U-rod 13 is fixed to the top of the sealing plug 8. The support 7 is fixedly installed on the right side of the pressure relief port 6. A movable recess is provided on the top of the support 7. One end of the linkage U-rod 13 slides in the movable recess, and the other end of the linkage U-rod 13 is vertically fixed to the top of the sealing plug 8. The sealing plug 8 can be removed from the top of the pressure relief port 6 by moving the linkage U-rod 13.

[0033] A limiting seat 17 located above the support 7 is sleeved on the outer wall of the linkage U-rod 13, and an elastic element 16 sleeved on the outer wall of the linkage U-rod 13 is provided between the limiting seat 17 and the support 7. The elastic element 16 is a compression spring, and its two ends are fixed to the opposite surfaces of the limiting seat 17 and the support 7, respectively. At the same time, the elastic element 16 slides and extends against the outer wall of the linkage U-rod 13.

[0034] During the maintenance and depressurization operation of oil tank 1, the linkage U rod 13 is moved upward, causing the linkage U rod 13 to simultaneously drive the sealing plug 8 and the limiting seat 17 to move. This causes the limiting seat 17 to stretch the elastic element 16 and generate elastic force. At this time, the depressurization port 6 opens. After depressurization, the elastic force of the elastic element 16 is used to drive the limiting seat 17 to drive the sealing plug 8 to embed into the depressurization port 6 through the linkage U rod 13, making the depressurization operation more convenient.

[0035] In addition, an elastic plug 15 is fixedly attached to the bottom of the sealing plug 8, forming a stepped blockage with the sealing plug 8. The elastic plug 15 is made of rubber, and its stepped shape allows it to be tightly engaged with the pressure relief port 6 at the top of the inner cavity. This ensures the sealing of the hydraulic port 6.

[0036] In addition, the telescopic component includes a base 5 fixed to the inner wall of the oil tank 1, and a sliding rod 4 that penetrates the inner cavity of the base 5 is fixed to the bottom of the outer wall of the capsule frame 2. One end of a bracket 14 is vertically fixedly installed on the inner wall of both sides of the oil tank 1, and the other end of the bracket 14 is fixedly installed on the outer wall of the base 5. A through hole penetrating the inner cavity is longitudinally opened on the base 5, so that the sliding rod 4 slides against the inner wall of the through hole.

[0037] When the oil level changes in the oil tank 1, the capsule holder 2 moves with the oil surface, thus ensuring that the capsule inside the oil tank 1 moves with the capsule holder 2 and that the capsule is stably attached to the oil surface.

[0038] Furthermore, a detachable anti-detachment seat 20 is fixed to the bottom end of the slide rod 4. The detachable anti-detachment seat 20 allows the slide rod 4 to be separated from the base 5. The top of the anti-detachment seat 20 is provided with a threaded hole, and the bottom of the outer wall of the slide rod 4 is provided with an external thread, so that the slide rod 4 and the anti-detachment seat 20 are threadedly connected. By removing the anti-detachment seat 20, the capsule holder 2 can be easily disassembled and assembled.

[0039] An oil inlet 11 is embedded in the top of the oil tank 1, and a baffle plate 12 is fixedly attached to the oil tank 1 above the oil inlet 11. The oil inlet 11 is fixedly embedded in the top of the outer wall of the oil tank 1, a valve is installed on the oil inlet 11, and an arc-shaped baffle plate 12 is fixedly installed on the top of the outer wall of the oil tank 1 to protect the area above the oil inlet 11.

[0040] A connecting bracket 18 is fixed to the bottom of the outer wall of the oil conservator 1. The oil conservator 1 is fixed to the transformer through two connecting brackets 18, making the installation process of the oil conservator more convenient.
