Description

Technical Field

[0001] This utility model specifically relates to a busbar trunking based on direct connection of distribution cabinet terminals. Background Technology

[0002] Busbar trunking is a closed metal device consisting of copper or aluminum busbars as conductors, wrapped with insulation or supported by insulating components, and encased in aluminum or steel. It is used to transmit electrical energy and has the ability to collect and distribute power. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Currently, busbar trunking is connected to the distribution cabinet using a starting box. However, this connection method takes up more space in the electrical equipment installation and adds a transfer link, which reduces power output efficiency and increases the amount of connecting copper busbars, thus increasing costs. Utility Model Content

[0004] The purpose of this invention is to provide a busbar trunking based on direct connection of distribution cabinet terminals to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a busbar trunking based on direct connection of distribution cabinet terminals, comprising a distribution cabinet, a busbar trunking body, conductive copper busbars, a protective shell, and a limiting component. The busbar trunking body is directly connected to the top of the distribution cabinet. The conductive copper busbars are disposed within the busbar trunking body and protrude from both ends of the busbar trunking body. The protective shell is installed and removed from the outside of the conductive copper busbars through the limiting component to achieve protection.

[0006] Preferably, the protective shell has a cavity adapted to the conductive copper busbar, and the limiting component includes grooves on the upper and lower sides of the cavity.

[0007] Preferably, springs are provided on both the left and right sides of the groove, and a movable block is provided at one end of the two springs that are close to each other. The movable block extends out of the groove through an opening and is connected to an insert plate.

[0008] Preferably, the groove has sliding grooves on both the upper and lower sides, and a sliding rod is provided in the sliding groove, which is connected to the moving block.

[0009] Preferably, the protective shell has a strip groove on its back side, the strip groove is connected to the groove, and two push rods are inserted into the strip groove.

[0010] Preferably, the two push rods extend into the groove through a strip and are connected to the moving block.

[0011] Preferably, a limiting groove is formed on the surface of the busbar trunking body.

[0012] The technical effects and advantages of this utility model are as follows: This busbar trunking based on direct connection to the distribution cabinet terminals uses a pre-set connection port on the busbar trunking body that matches the shape of the distribution cabinet terminals. High-strength bolts are used to tightly fix the busbar trunking to the distribution cabinet terminals, achieving direct connection. Simply align the beginning of the busbar trunking with the distribution cabinet terminal position and tighten the bolts to complete the connection. The operation is simple and efficient. The direct connection method eliminates the complicated intermediate transfer links, shortens the current transmission path, and reduces the line resistance. Lower resistance means that the power loss during current transmission is reduced as heat, thereby improving power transmission efficiency, reducing intermediate connecting parts, and reducing the risk of failures such as overheating and arcing caused by poor contact. Meanwhile, the overall connection structure is more robust, capable of withstanding greater electrodynamic and mechanical vibrations, adapting to complex and ever-changing industrial environments and harsh working conditions, enhancing the stability and reliability of system operation. The direct connection between the busbar trunking and the distribution cabinet makes the overall layout more compact, effectively saving space within the limited electrical equipment installation space, and providing more possibilities for the rational layout of other equipment. It is especially suitable for places such as data centers and power distribution rooms in high-rise buildings where space utilization is extremely important. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] To protect the conductive copper busbar 3, refer to Figure 1 , Figure 2 and Figure 3 As shown, the system includes a distribution cabinet 1, a busbar trunking body 2, conductive copper busbars 3, a protective shell 4, and a limiting assembly. The busbar trunking body 2 is directly connected to the top of the distribution cabinet 1. The conductive copper busbars 3 are installed inside the busbar trunking body 2 and protrude from both ends of the busbar trunking body 2. The protective shell 4 is installed and removed from the outside of the conductive copper busbars 3 through the limiting assembly to provide protection. Pressing the two insert plates 8 brings them closer together. As the sliding rod 10 slides along the length of the sliding groove 9, it drives the two moving blocks 7 to move along with it, bringing the two moving blocks 7 closer together. Then, the insert plates 8 are inserted into the limiting groove 13, at which point the insert plates 8 are no longer pressed. Force, spring 6 deforms, and the elastic force reacts to the moving block 7, causing the two moving blocks 7 to move away from each other, and driving the two insert plates 8 to move away from each other, so as to insert into the limiting groove 13 to complete the installation of the protective shell. The protective shell can protect the conductive copper busbar 3 and is easy to install. The busbar trunking body 2 is pre-set with a connection port that matches the shape of the terminal head of the distribution cabinet 1. The busbar trunking body 2 and the terminal head of the distribution cabinet 1 are tightly fixed with high-strength bolts to achieve direct connection. Just align the beginning of the busbar trunking body 1 with the terminal head of the distribution cabinet 2 and tighten the bolts to complete the connection. The operation is simple and efficient. The direct connection method eliminates the complicated intermediate conversion links.

[0023] For easier disassembly and assembly of the protective case, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the protective shell has a cavity adapted to the conductive copper busbar 3. The conductive copper busbar 3 can be inserted into the cavity, forming independent protection for the conductive copper busbar 3, preventing damage to the conductive copper busbar 3 and preventing impurities from adhering to the surface of the conductive copper busbar 3, thereby improving the service life of the busbar trunking body 2. The limiting component includes grooves 5 on the upper and lower sides of the cavity. Springs 6 are provided on both the left and right sides of the grooves 5. Movable blocks 7 are provided at the ends of the two springs 6 close to each other. The movable blocks 7 extend outside the grooves 5 through openings and are connected to insert plates 8. When the two movable blocks 7 approach each other, the two springs 6 are stretched, and the two insert plates 8 are moved closer to each other at the same time. Sliding grooves 9 are provided on both the upper and lower sides of the grooves 5. Sliding rods 10 are provided in the sliding grooves 9. The sliding rods 10 are connected to the movable blocks 7. The sliding rods 10 slide along the length of the sliding grooves 9, which supports the movable blocks 7, facilitates the sliding of the movable blocks 7, and improves the stability of the movable blocks 7 during the sliding process. The protective shell has a strip groove 11 on its back side, which is connected to the groove 5. Two push rods 12 are inserted into the strip groove 11. The two push rods 12 extend through the strip groove 11 into the groove 5 and connect to the moving block 7. When removal is required, the two push rods 12 are moved and slid in opposite directions, causing the two moving blocks 7 and the insertion plate 8 to move away, thereby pulling the insertion plate 8 out of the limiting groove 13. The busbar trunking body 2 has a limiting groove 13 on its surface, with both sides of the limiting groove 13 extending outward to facilitate the insertion of the insertion plate 8. The top box of the distribution cabinet 1 is eliminated, and the beginning is directly connected to the busbar inside the distribution cabinet 1. The direct connection saves the installation of the top box, is more convenient and faster, and saves the amount of connecting copper busbars, reducing resource waste and cost loss. The direct connection eliminates the complicated intermediate transfer links, shortens the current transmission path, and reduces line resistance. According to Joule's law Q=I²Rt (where Q is the heat generated by the current, I is the current, R is the resistance, and t is time), a decrease in resistance means that the energy loss during current transmission is reduced as heat, thereby improving the efficiency of power transmission.

[0024] In use, first press the two insert plates 8 to bring them closer together. As the slide bar 10 slides along the length of the slide groove 9, it moves the two moving blocks 7 along with it, bringing them closer together. Then, insert the insert plates 8 into the limiting groove 13. At this point, the insert plates 8 lose their squeezing force, the spring 6 deforms, and the elastic force reacts to the moving blocks 7, causing the two moving blocks 7 to move away from each other, thus moving the two insert plates 8 away from each other and inserting them into the limiting groove 13, completing the installation of the protective shell. The protective shell can protect the conductive copper busbar 3. To remove it, move the two levers in opposite directions. As the slide bar 10 slides, it moves the two moving blocks 7 away from each other, causing the two insert plates 8 to be pulled out of the limiting groove 13, completing the removal of the protective shell.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
