Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to an insulated and dense bus duct. Background Technique

[0002] A bus duct is a closed metal device composed of copper and aluminum bus bars, used to distribute relatively large power to each component of a decentralized system, and has increasingly replaced wire and cable in indoor low-voltage power transmission trunk line engineering projects.

[0003] Most of the current conductive sheets of bus ducts are gathered together and then connected to the main body through an insulating protective sleeve to enable their use. However, when the bus duct conducts current, the metal materials inside will generate heat, which may damage the set insulating protective sleeve, resulting in its inability to perform the insulating function and further causing damage to the device.

[0004] Therefore, we propose an insulated and dense bus duct. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an insulated and dense bus duct.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An insulated and dense bus duct includes a device main body and a partition mechanism arranged inside the device main body. The partition mechanism includes a placement bin, sealing plates arranged at both ends of the device main body, and heat dissipation plates arranged inside the placement bin. Each placement bin is internally provided with a conductive plate. The placement bin is used for separating and placing a plurality of the conductive plates, and the heat dissipation plates are used for dispersing the heat of the conductive plates.

[0008] As a further scheme of the utility model: The sealing plates are fixedly arranged at opposite ends of the device main body, and a plurality of sliding grooves corresponding to the positions and quantities of the conductive plates are formed on the sealing plates.

[0009] As a further scheme of the utility model: The heat dissipation plates are located on both sides of the conductive plates, and a plurality of heat conduction grooves are formed on one side of the heat dissipation plates close to the conductive plates.

[0010] As a further scheme of the utility model: An insulating sheet is arranged between the heat dissipation plates and the conductive plates.

[0011] As a further scheme of the utility model: At least two dry powder placement sleeves are fixedly arranged inside the placement bin, and the dry powder placement sleeves are located on one side of the heat dissipation plates away from the conductive plates.

[0012] As a further solution of the present utility model: protective plates are further provided at opposite ends of the device main body, and the protective plates are used for protecting the conductive plates.

[0013] As a further solution of the present utility model: a connecting frame is fixedly provided on one side of the protective plate, and the connecting frame is threadedly engaged with the device main body through a fastening bolt.

[0014] Compared with the prior art, the present utility model provides an insulated compact busway, which has the following beneficial effects:

[0015] 1. In the present utility model, if each conductive plate is in contact, it will cause the temperature to further increase, which will further lead to the potential of fire inside the device main body. And when multiple conductive plates are placed separately, the impact on the conductive plates of other parts when a fire occurs in a single part is minimal. The placement bin can provide a layer of protection for the whole device main body, increasing the fire resistance of the device main body. At the same time, separating the installation of the conductive plates can minimize the possibility of mutual power transmission, and an insulating device is provided, so that the safety can be improved during use.

[0016] 2. In the present utility model, dry powder placement sleeves are fixedly provided on the inner walls of each placement bin. When a fire occurs inside a single placement bin, the dry powder placement sleeves can be burned through, so that the stored dry powder inside can burst out, thereby extinguishing the small-scale fire inside the placement bin, effectively preventing the spread of the fire. At the same time, insulating sheets are provided on both sides of the conductive plate to isolate the electromagnetic field of a single conductive plate.

[0017] Parts not involved in this device are the same as the prior art or can be realized by using the prior art. The structure of the present utility model is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment: An insulated and dense busbar, as Figures 1 - 4 shown, includes a device main body 1 and a partitioning mechanism arranged inside the device main body 1. The partitioning mechanism includes a placing bin 5, sealing plates 6 arranged at both ends of the device main body 1, and a heat dissipation plate 9 arranged inside the placing bin 5. Each placing bin 5 is internally provided with a conductive plate 3. The placing bin 5 is used for separately placing multiple conductive plates 3, and the heat dissipation plate 9 is used for dispersing the heat of the conductive plates 3. By arranging the placing bin 5 inside the device main body 1, the device main body 1 can use the placing bin 5 to separately install each conductive plate 3, thereby avoiding multiple conductive plates 3 heating up simultaneously when in use. If each conductive plate 3 is in contact, this will cause the temperature to further increase, and then there is a tendency for a fire to occur inside the device main body 1. Moreover, when the multiple conductive plates 3 are separately placed, the impact on the conductive plates 3 of other parts when a fire occurs in a single part is also minimal. The placing bin 5 can provide a layer of protection for the whole device main body 1, enabling the fire resistance of the device main body 1 to increase. At the same time, separately installing the conductive plates 3 can minimize the possibility of mutual power transmission. At the same time, an insulating device is provided, so that the safety can be improved during use.

[0026] As Figures 1 - 4As shown in the figure, the sealing plates 6 are fixedly arranged at the opposite two ends of the device main body 1, and a plurality of chutes 7 corresponding to the positions and quantities of the conductive plates 3 are arranged on the sealing plates 6. The heat dissipation plates 9 are located on both sides of the conductive plates 3. A plurality of heat conduction grooves 10 are arranged on one side of the heat dissipation plates 9 close to the conductive plates 3. By fixedly arranging the sealing plates 6 on both sides of the device main body 1, the device main body 1 can use the sealing plates 6 to seal its two ends. At the same time, the chutes 7 arranged on the sealing plates 6 can enable the conductive plates 3 to extend to the outside, so that a plurality of different conductive plates 3 can be connected. By arranging the heat conduction grooves 10, the heat conduction grooves 10 are used for heat diversion. At the same time, heat dissipation plates 9 are arranged on both sides of the conductive plates 3, and both the upper half and the lower half of the heat dissipation plates 9 can extend to the outside of the device main body 1. At the same time, the connection parts of the upper half and the lower half of the heat dissipation plates 9 with the device main body 1 are welded. Thus, not only can the heat dissipation effect of the conductive plates 3 be achieved, but also the sealing effect of the device main body 1 will not be reduced. At the same time, the heat dissipation plates 9 are made of materials with good heat conductivity. At the same time, the insulating sheets 11 arranged between the heat dissipation plates 9 and the conductive plates 3 can isolate the current, avoiding the attachment of current on the heat dissipation plates 9. And the insulating sheets 11 are insulating polyester sheets, and the insulating effect is better.

[0027] As Figures 1 - 4 shown, an insulating sheet 11 is arranged between the heat dissipation plate 9 and the conductive plate 3. At least two dry powder placement sleeves 8 are fixedly arranged inside the placement bin 5. The dry powder placement sleeves 8 are located on the side of the heat dissipation plate 9 away from the conductive plate 3. By fixedly arranging the dry powder placement sleeves 8 on the inner walls of each placement bin 5, when a fire breaks out inside a single placement bin 5, the dry powder placement sleeves 8 can be burned through, so that the dry powder stored inside can burst out, thereby extinguishing the small-scale fire inside the placement bin 5, effectively avoiding the spread of the fire. At the same time, arranging the insulating sheets 11 on both sides of the conductive plate 3 can isolate the electromagnetic field of a single conductive plate 3, avoiding sparks caused by the powder touching the electricity and causing more serious accidents.

[0028] As Figures 1 - 4 shown, protective plates 2 are also arranged at the opposite two ends of the device main body 1. The protective plates 2 are used for protecting the conductive plates 3. A connecting frame 101 is fixedly arranged on one side of the protective plates 2. The connecting frame 101 is in threaded engagement with the device main body 1 through a fastening bolt 4. By arranging the protective plates 2 on both sides of the device main body 1, the device main body 1 can use the protective plates 2 to protect the conductive plates 3 to a certain extent, avoiding damage to the conductive plates 3 due to external forces during transportation. At the same time, arranging the connecting frame 101 in threaded engagement with the device main body 1 through the fastening bolt 4 can make the overall connection more stable.

[0029] Working principle: The main body 1 of the device separates and installs each conductive plate 3 by using the placement bin 5, so as to prevent multiple conductive plates 3 from heating up simultaneously when in use. If each conductive plate 3 is not in contact, the temperature will further increase, which may lead to a potential for fire inside the main body 1 of the device. Moreover, separating and placing multiple conductive plates 3 has a minimal impact on the conductive plates 3 in other parts when a fire occurs in a single part. If a fire breaks out inside a single placement bin 5, it will burn through the dry powder placement sleeve 8, causing the dry powder stored inside to explode, thereby extinguishing the small-scale fire inside the placement bin 5 and effectively preventing the spread of the fire. The placement bin 5 can provide a layer of protection for the entire device main body 1, increasing its fire resistance. At the same time, separating and installing the conductive plates 3 can minimize the possibility of mutual power transmission, thereby enhancing the safety during use.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
