Description

Technical Field

[0001] This utility model relates to the field of transformer protection technology, specifically a transformer vertical multi-angle protective cover. Background Technology

[0002] In power distribution networks, the joints of outdoor equipment such as pole-mounted circuit breakers and pole-mounted transformers are exposed and need to be protected. Currently, silicone rubber sleeves or insulating covering materials are used for wrapping.

[0003] However, the current approach has many shortcomings: 1. The currently used silicone rubber sleeves cannot completely seal the water. They are not only not waterproof, but water can also accumulate inside the sleeves, causing metal corrosion and loosening of fasteners, which directly leads to poor contact and secondary failures. 2. The silicone rubber sheath is made of soft material and is fastened by buckles. Due to aging and exposure to wind and sun, the buckles are prone to loosening and may even fall off completely under external force, losing their protective function. Moreover, problems are not easily detected, which seriously affects the safe and stable operation of the power grid. To ensure safe operation, it needs to be replaced on average every 3 years. The replacement work is large and the maintenance cost is high. 3. Because the silicone rubber sheath cannot be tightly bonded to the metal, an air insulation layer is formed. The thermal conductivity of air is approximately 0.0244 W / m·K, which is not good for heat conduction. Therefore, it is not possible to accurately measure the temperature at the metal connection from the outside. 4. When using insulating covering materials for insulation, the quality of the covering depends entirely on the construction personnel. The covering thickness cannot be determined or measured. Furthermore, the covering material cannot be tightly bonded to the metal, making it impossible to prevent rainwater from penetrating. At the same time, the covering material is expensive, increasing costs without achieving good results. Therefore, a transformer vertical multi-angle protective cover is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a transformer vertical multi-angle protective cover to solve the problems of poor protective effect and inconvenient installation of existing protective covers mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A transformer vertical multi-angle protective cover includes a compatible base assembly. An adaptive connector is mounted on the top of the compatible base assembly, and an inclined multi-angle compatible top seat is mounted on the top of the adaptive connector. The compatible base assembly includes a left base and a right base. A connecting ring that connects to the adaptive connector is provided on the top of the compatible base assembly. A first curved connection area is provided on the top of the adaptive connector, and a second curved connection area that rotatably connects to the first curved connection area is provided on the bottom of the multi-angle compatible top seat. An injection port is provided on the top of the multi-angle compatible top seat. Both the adaptive connector and the multi-angle compatible top seat are designed as left and right halves corresponding to the left and right bases, respectively. The components in the compatible base assembly and the adaptive connector are connected by hinges and can rotate axially. The compatible base assembly, the adaptive connector, and the multi-angle compatible top seat are all fixed by fixing components, and sealing components are provided at their inner edges.

[0006] Preferably, the adaptive connector has a connection hole, the multi-angle compatible top seat has a connection post corresponding to the connection hole, and a connection cap is installed on the connection post.

[0007] Preferably, the bottom of the adaptive connector is provided with a cylindrical connecting area.

[0008] Preferably, the inner diameter of the second curved connecting area is larger than the outer diameter of the first curved connecting area, and the second curved connecting area is fitted outside the first curved connecting area.

[0009] Preferably, the connecting hinge includes a first connector and a second connector, which are connected by concentric pillars to form surface-to-surface constraints.

[0010] Preferably, the fixing component includes a fixing buckle and a buckle overlap plate.

[0011] Preferably, the sealing assembly includes a male stop and a female stop.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The wiring connection of the equipment is properly covered. Traditional protection measures only wrap a layer of silicone rubber sheath around the wiring connection. The shape of the sheath itself is not fixed, and it cannot be guaranteed that the internal conductor will be completely covered during the installation process, which may expose the conductor. This utility model uses rigid insulating material and is designed according to the shape of the wiring connection. After installation, it can completely cover the conductor at the wiring connection and there is no problem of inadequate coverage. 2. It can ensure sufficient insulation distance. Traditional silicone rubber sheaths are soft due to their material properties, and there may be insufficient gap between the sheath and the internal conductor. This utility model uses a rigid material and is designed with reference to the shape of the wiring point to ensure that there is a sufficient safe distance between the internal conductor and the conductor. 3. Easy to install. Traditional silicone rubber sleeves are soft and have irregular shapes, requiring two hands to install them one by one, which takes a long time, is difficult, and is easy to misinstall. This utility model has a simple installation process, comes with clips, and can be installed with one hand, and can be installed in place in one go. 4. Cost reduction: This utility model provides a container for injecting insulating material, ensuring that the conductors at the equipment wiring points are properly covered. After the insulating material has completely solidified, it can guarantee 10 years of protective performance, which is much less than the traditional protective measures that need to be replaced every 2-3 years, greatly reducing costs. 5. This utility model has a built-in vertically movable structure, which can adapt to different installation heights of the terminals on the terminals of the pole-mounted transformer equipment. Compared with the traditional integrated sheath, this utility model is more flexible in structure, avoiding the situation where the sheath cannot be fully covered and exposed due to different installation heights of the terminals. 6. This utility model has a built-in vertical angle adaptive structure, which can adapt to various wiring forms and equipment types. Compared with the traditional sheath, which can only be used at one angle, it has a wider range of applications, making it more convenient for on-site construction personnel to operate and reducing construction difficulty. 7. Convenient and efficient selection: The vertically movable structure and vertical angle adaptive structure of this utility model do not require confirmation of specific equipment information. Only the types of connecting terminals and hardware are needed to select the appropriate protective cover, which provides convenience for selection. 8. The inventory preparation is simple and efficient. This utility model can replace various types of silicone rubber sleeves applicable to pole-mounted transformer equipment, and can solve the problems caused by too many sleeve models and the incompatibility between different models of sleeves.

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.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0017] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0018] Please see Figure 1-11 This utility model provides a technical solution: A transformer vertical multi-angle protective cover includes a compatible base assembly 1, an adaptive connector 2 mounted on the top of the compatible base assembly 1, and an inclined multi-angle compatible top mount 3 mounted on the top of the adaptive connector 2. The compatible base assembly 1 includes a left base 11 and a right base 12, and a connecting ring 13 connected to the adaptive connector 2 is provided on the top of the compatible base assembly 1. The adaptive connector 2 has a first curved connection area 21 on its top, and the multi-angle compatible top mount 3 has a second curved connection area 31 rotatably connected to the first curved connection area on its bottom. The multi-angle compatible top mount 3 has an injection port 32 on its top. The adaptive connector 2 and the multi-angle compatible top mount 3 are both left and right halves corresponding to the left base 11 and the right base 12. In some designs, the components in the compatible base assembly 1 and the adaptive connector 2 are connected by connecting hinges 5 and can rotate axially. The compatible base assembly 1, the adaptive connector 2, and the multi-angle compatible top seat 3 are all fixed by fixing components 6, and sealing components 7 are provided at their inner edges. This utility model uses rigid insulating material, and the design process refers to the shape of the equipment wiring point. After installation, it can completely cover the conductor at the equipment wiring point, eliminating the possibility of incomplete coverage and reducing costs. This utility model provides a container for injecting insulating material, ensuring that the conductor at the equipment wiring point is properly covered. After the insulating material has completely solidified, it can guarantee 10 years of protective performance, which is much lower than the traditional protective measures that need to be replaced every 2-3 years, greatly reducing costs.

[0019] The adaptive connector 2 has a connecting hole 22, and the multi-angle compatible top seat 3 has a connecting post 33 corresponding to the connecting hole 22. A connecting cap 4 is installed on the connecting post 33. The connecting post 33, the connecting hole 22 and the connecting cap 4 are connected to each other, so that the adaptive connector 2 and the multi-angle compatible top seat 3 form a whole, thereby enabling the first curved connection area 21 and the second curved connection area 31 to rotate relative to each other.

[0020] The bottom of the adaptive connector 2 is provided with a cylindrical connection area 23. This design gives the present invention a vertically movable structure, which can adapt to different installation heights of the terminals on the terminals of the pole-mounted transformer equipment. Compared with the traditional integrated sheath, the present invention is more flexible in structure and avoids the situation where the sheath cannot be fully covered and exposed due to different installation heights of the terminals.

[0021] The connecting hinge 5 includes a first connector 51 and a second connector 52. The first connector 51 and the second connector 52 are connected by a concentric column 53 to form a surface constraint, which forms an axial limiting constraint on the two bases and enables the two bases to achieve a rotational closure effect.

[0022] The fixing component 6 includes a fixing buckle 61 and a buckle overlap plate 62. The design of the fixing component 6 is such that after the device is closed, the fixing buckle 61 forms a surface constraint with the surface of the buckle overlap plate 62 through its own plane, so as to achieve the purpose of locking after the device is closed.

[0023] The sealing assembly 7 includes a male stop plate 71 and a female stop plate 72. The design of the sealing assembly 7 is such that after the device is closed, the male stop plate 71 will be inserted into the female stop plate 72, so that the two components form a face-to-face contact to achieve a sealing effect.

[0024] Workflow: When it is necessary to use the device to protect the transformer joint, first open the compatible base assembly 1 to separate the left base 11 and the right base 12. Place it on the top outside of the transformer joint and then close the left base 11 and the right base 12. After merging, the fixing buckle 61 will engage with the buckle overlap plate 62 to fix the compatible base assembly 1. The male stop plate 71 will be inserted into the female stop plate 72 to seal the compatible base assembly 1. Afterwards, the adaptive connector 2 and the multi-angle compatible top seat 3 can be installed. The connecting column 33, the connecting hole 22 and the connecting cap 4 are connected to each other so that the adaptive connector 2 and the multi-angle compatible top seat 3 form a whole. This allows the first curved connection area 21 and the second curved connection area 31 to rotate relative to each other. Therefore, when the adaptive connector 2 is opened, the multi-angle compatible top seat 3 will also open. After placing it on the top of the outside of the compatible base assembly 1, it will be closed. The fixing assembly 6 and the sealing assembly 7 will fix and seal the adaptive connector 2 and the multi-angle compatible top seat 3 respectively. This completes the fixed installation of the device. Because of the connection ring 13 and the cylindrical connection area 23, the adaptive connector 2 can move up and down when it is installed, so that the device can adapt to different installation heights of the terminals on the pole-mounted transformer equipment terminals. Compared with the traditional integrated sheath, the structure of this utility model is more flexible, avoiding the situation where the sheath cannot be fully covered and exposed due to different installation heights of the terminals. During installation, gaps may exist between the bottom of the device and the transformer insulator, between the top of the device and the cable insulation layer, and between the connecting structures of each section of the device. These gaps can affect the overall installation stability of the device and cause the insulating material to flow out. Therefore, during installation, the gaps in the corresponding positions can be filled with sealing gaskets, filling sponges, or other sealing materials to form a sealed container, preventing the insulating material from flowing out during injection and also providing a certain degree of limitation for the overall installation of the device. This utility model uses rigid insulating material. After the device is fixedly installed, a rigid insulating container can be formed. At this time, the insulating material can be injected into the compatible base assembly 1, the adaptive connector 2 and the multi-angle compatible top seat 3 through the injection port 32. After the insulating material is completely solidified, it can guarantee 10 years of protective performance. Compared with the traditional protective measures that need to be replaced every 2-3 years, the cost is greatly reduced. The design of the sealing component 7 allows the male stop plate 71 to insert into the female stop plate 72 after the device is closed, so that the two components form a face-to-face contact to achieve a sealing effect. The design of the fixing component 6 allows the fixing buckle 61 to form a surface constraint with the plane of the buckle overlap plate 62 after the device is closed, thereby achieving the purpose of locking after the device is closed. The design of the connecting hinge 5 allows the first connecting piece 51 and the second connecting piece 52 to form a surface constraint through the concentric column 53, which not only forms an axial limiting constraint on the bases on both sides, but also enables the bases on both sides to achieve a rotational closure effect.

[0025] Please see Figure 12-13 This utility model provides a technical solution: The inner diameter of the second curved connecting area 31 is larger than the outer diameter of the first curved connecting area 21, and the second curved connecting area 31 is fitted outside the first curved connecting area 21.

[0026] Since the inner diameter of the second curved connection area 31 is larger than the outer diameter of the first curved connection area 21, the second curved connection area 31 can protect the first curved connection area 21 and prevent rainwater from entering the device and causing water to accumulate.
