Description

Technical Field

[0001] The utility model belongs to the technical field of enclosed busbars, and more specifically, relates to a sealing kit for an enclosed busbar passing through a wall. Background Art

[0002] In modern power systems, busbars are important electrical devices, usually made of copper or aluminum conductive bars or rods for distributing electricity. Busbars play a crucial role in power facilities as they are responsible for transmitting electricity from the power source to various load points. Depending on their usage environment and functions, busbars can be classified into various types such as exposed busbars and enclosed busbars.

[0003] As the name implies, an enclosed busbar is a busbar completely wrapped in insulating materials. This type of busbar is mainly used in high-voltage power systems to provide additional safety protection measures, prevent electric shock to personnel, and reduce the impact of electromagnetic interference on surrounding electronic devices. The advantage of an enclosed busbar is that it can operate in various harsh environments, such as humid and dusty places, or even areas with the presence of some hazardous gases. The outer shell of an enclosed busbar is usually made of metal, which can not only protect the internal conductors from the external environment but also serve as a good grounding and shielding device.

[0004] However, in practical applications, when an enclosed busbar needs to pass through a wall or other obstacles, problems such as poor sealing and inconvenient sealing may occur. This is because the structure of the wall or other obstacles may damage the protective layer of the enclosed busbar, thereby affecting its sealing performance and protective capabilities. If appropriate sealing measures are not taken, external moisture, dust, or other impurities may enter the interior of the enclosed busbar, affecting its normal operation and even causing safety accidents such as short circuits. Summary of the Utility Model

[0005] In view of this, the utility model provides a sealing kit for an enclosed busbar passing through a wall, which can provide sealing for the enclosed busbar passing through the wall, avoid gaps between the busbar and the wall, and facilitate installation.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a sealing kit for an enclosed busbar passing through a wall, including an enclosed busbar outer shell and a sealing kit. Among them, the enclosed busbar outer shell is a rectangular cylinder for accommodating the busbar conductor and providing protection and shielding. A depression is provided at the middle part of the enclosed busbar outer shell where it passes through the wall, and the depression is used to accommodate the sealing kit. The sealing kit is a cuboid cylinder, and its inner diameter is adapted to the depression part of the enclosed busbar outer shell. The cross-section of the sealing kit has a slope, and the thickness of the side entering the wall is less than the thickness of the side exposed outside the wall.

[0008] The technical effects of a closed busbar through-wall sealing kit provided by the present utility model are as follows: The closed busbar through-wall sealing kit provided by this utility model ensures effective sealing when the busbar passes through the wall by setting a depression at the through-wall part of the closed busbar housing to accommodate the sealing kit. The sealing kit is designed as a cuboid cylinder, and its cross-section has a slope. The thickness on the side entering the wall is smaller, which is convenient for installation; while the thickness on the side exposed outside the wall is larger, which can provide better sealing effect, prevent external moisture, dust, etc. from invading the inside of the closed busbar housing, and ensure the normal operation of the busbar conductor. This design not only simplifies the installation process, but also improves the sealing performance, reduces the maintenance cost, is applicable to power transmission systems in various building environments, and enhances the reliability and safety of the entire system.

[0009] On the basis of the above technical solution, a closed busbar through-wall sealing kit of the present utility model can also be improved as follows:

[0010] Among them, a fastening band is provided on the thinner side of the sealing kit. The fastening band is U-shaped, and the two ends of the U-shape are integrally formed with the thinner side of the sealing kit. Correspondingly, a fixing hook for fixing the fastening band is provided on the outer side of the depression on the closed busbar housing.

[0011] Furthermore, the fixing hook is a protrusion on the closed busbar housing. The protrusion is an inverted L shape, and the fixing hook is bent in a direction away from the depression on the closed busbar housing.

[0012] Furthermore, the fixing hook is a depression on the closed busbar housing, and the width of the top of the depression is smaller than the width of the top of the depression.

[0013] Furthermore, the cross-section of the sealing kit is a triangle, and the two right-angled sides of the triangle satisfy the relationship a = 2b, where a is the horizontal right-angled side and b is the vertical right-angled side.

[0014] The beneficial effects of adopting the above improvement scheme are as follows: Designing the cross-section of the sealing kit as a triangle, and the two right-angled sides satisfy the relationship a = 2b (where a is the horizontal right-angled side and b is the vertical right-angled side). Such a design can ensure that the front end of the sealing kit is thinner and more convenient to insert into the installation position in the wall. At the same time, since the length of side a is twice that of side b, the thickness of the rear end of the sealing kit increases, providing better sealing effect and stability. The thicker end can better resist the influence of external environmental factors, such as temperature changes or vibrations, etc., reduce the possibility of air and moisture penetration, and thus protect the conductor inside the closed busbar housing from damage, ensuring the safety and reliability of power transmission. The design of this geometric structure not only simplifies the installation process, but also enhances the sealing performance of the entire system.

[0015] Further, the shape of the cross-section of the sealing kit is an exponential function.

[0016] The beneficial effects of adopting the above improvement scheme are as follows: When the cross-section of the sealing kit adopts the shape of an exponential function, this non-linear design can bring better adaptability and sealing performance. The characteristics of the exponential function determine that its thickness gradually but non-uniformly increases as it penetrates deeper into the wall. This enables the sealing kit to more easily adapt to the uneven surface of the wall during the installation process while ensuring a good sealing effect. The exponential shape design can also effectively disperse stress, reduce the risk of damage caused by local stress concentration, and improve the durability of the overall structure. In addition, this design helps to improve the situation of thermal expansion and contraction, reduce the problem of sealing failure caused by temperature changes, and further enhance the long-term stability and safety of the wall-penetrating part of the enclosed busbar.

[0017] Further, there are two sealing kits, including a first seal and a second seal. A horizontal through-hole is provided on the first seal, and the through-hole is used to accommodate the passage of the second seal.

[0018] Further, there are two through-holes for accommodating two sides of the fastening belt.

[0019] Further, the bottom of the first seal and the second seal are provided with recesses and protrusions arranged alternately with each other for accommodating the fastening belt at the bottom of the first seal and the second seal.

[0020] Further, the material of the sealing kit is rubber or polyurethane.

[0021] Both rubber and polyurethane have good elasticity and weather resistance, and can maintain their physical properties within a wide temperature range, ensuring that the sealing kit can maintain a good sealing effect even in harsh environments. The high elasticity of these materials allows the sealing kit to deform as necessary during the installation process to adapt to the irregular surface of the wall, and at the same time ensures that it returns to its original shape and fits tightly after installation, effectively preventing the intrusion of water vapor and dust. In addition, rubber and polyurethane have strong chemical stability and are not easily affected by corrosive substances, extending the service life of the sealing kit. The selection of these two materials not only improves the sealing performance but also enhances the safety and reliability of the entire system.

[0022] Compared with the prior art, the beneficial effects of a wall-penetrating sealing kit for an enclosed busbar provided by the present utility model are as follows:

[0023] Simplify the installation process: By designing a sloped structure on the cross-section of the sealing kit, the front end is relatively thin and easy to insert into the installation position in the wall; the cross-section of the sealing kit is designed as a triangle, and the two right-angled sides satisfy the relationship of a = 2b, ensuring that the front end is easy to insert into the wall and simplifying the installation steps;

[0024] Improve sealing performance: The rear end of the sealing kit has a larger thickness, which can provide a better sealing effect and effectively prevent the intrusion of external moisture, dust, etc. into the interior of the enclosed busbar housing; The use of a cross-section in the shape of an exponential function can better adapt to the uneven surface of the wall, while ensuring a good sealing effect and improving the sealing performance;

[0025] Enhance the stability and durability of the structure: The design in the shape of an exponential function helps to effectively disperse stress and reduce the risk of damage caused by local stress concentration; It can improve the situation of thermal expansion and contraction, reduce the problem of sealing failure caused by temperature changes, and enhance the long-term stability and safety of the part of the enclosed busbar passing through the wall;

[0026] Improve the adaptability and durability of materials: Rubber or polyurethane is used as the material of the sealing kit. These materials have good elasticity and weather resistance and maintain their physical properties within a wide temperature range; The high-elasticity materials allow the sealing kit to undergo the necessary deformation during installation to adapt to the irregular surface of the wall and ensure that it returns to its original shape and fits tightly after installation; These materials have strong chemical stability, are not easily affected by corrosive substances, and extend the service life of the sealing kit;

[0027] Improve the reliability and safety of the system: The material selection of the sealing kit and the improvement of its design work together to improve the reliability and safety of the entire system; By using a double-layer seal and a special fixing structure, the sealing effect and mechanical stability of the part of the enclosed busbar passing through the wall are further enhanced.

[0028] In summary, through a series of design improvements, the utility model not only simplifies the installation process, but also significantly improves the sealing performance, stability and durability of the enclosed busbar wall-penetrating sealing kit, ensuring the reliability and safety of the power transmission system.

[0051] Specifically, the principle of the present utility model is:

[0052] The enclosed busbar wall-penetrating sealing kit mainly consists of an enclosed busbar housing and a sealing kit. The enclosed busbar housing is a rectangular cylinder used to accommodate the busbar conductor and provide a protective shield. There is a depression at the wall-penetrating part of the busbar housing for installing the sealing kit. The sealing kit is designed as a cuboid cylinder, and its inner diameter matches the depressed part of the enclosed busbar housing. The cross-section of the sealing kit has a slope, with a smaller thickness on the side entering the wall for easy installation, and a larger thickness on the side exposed outside the wall to provide a better sealing effect, preventing external moisture, dust, etc. from invading the inside of the enclosed busbar housing, thus protecting the normal operation of the busbar conductor.

[0053] The combined use of the fastening strap and the fixing hook: The thinner side of the sealing kit is provided with a U-shaped fastening strap, which is integrally formed with the sealing kit. There are fixing hooks on the outside of the depression on the enclosed busbar housing for fixing the fastening strap. The fixing hook can be in the form of a protrusion, that is, an inverted L-shaped protrusion bent away from the depression on the enclosed busbar housing; it can also be in the form of a depression, that is, a depression with a small top width and a large bottom width;

[0054] The special design of the cross-section of the sealing kit: The cross-section of the sealing kit can be designed as a triangle, where the two right-angled sides satisfy the relationship a = 2b (a is the horizontal right-angled side, and b is the vertical right-angled side). This design makes the front end thinner for easy installation, while the rear end is thicker to provide better sealing and stability. In addition, the cross-section of the sealing kit can also adopt the shape of an exponential function. This non-linear design can better adapt to the uneven surface of the wall, ensure a good sealing effect, and help disperse stress, improving the durability of the structure;

[0055] The design of the double-layer seal: The sealing kit can be designed in two layers, including a first seal and a second seal. The first seal is provided with horizontal through holes for the second seal to pass through. There can be two through holes for accommodating the two sides of the fastening strap. The bottoms of the first seal and the second seal are provided with staggered depressions and protrusions for accommodating the fastening strap;

[0056] Material selection: The material of the sealing kit is rubber or polyurethane. These two materials have good elasticity and weather resistance, can maintain physical properties within a wide temperature range, and ensure that the sealing kit can maintain a good sealing effect in harsh environments. The high elasticity allows the sealing kit to deform as necessary during installation to adapt to the irregular surface of the wall, and at the same time ensures that it returns to its original shape and fits tightly after installation, effectively preventing the intrusion of water vapor and dust. In addition, rubber and polyurethane have strong chemical stability, are not easily affected by corrosive substances, and extend the service life of the sealing kit.

[0057] The enclosed busbar wall-penetrating sealing kit ensures effective sealing when the busbar passes through the wall by setting depressions and corresponding sealing kits at the wall-penetrating part of the enclosed busbar housing. The improved design simplifies the installation process, improves the sealing performance and the structural stability, and enhances the reliability and safety of the entire system by using the combination of fastening belts and fixing hooks, the special cross-section design of the sealing kit, and the selection of high-performance materials, etc.
