Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically relating to a durable busbar with a long service life. Background Technology

[0002] Busbar trunking is a power transmission system consisting of a metal sheet as a protective shell, internal conductive bars, insulation materials, and related connecting components. It is primarily used in power supply and distribution systems of industrial and mining enterprises, public institutions, and high-rise buildings. With the development of modern power engineering, it has become a widely adopted alternative to cable lines in outdoor power line installation and indoor power layout projects. However, traditional busbar trunking structures are prone to equipment failure during continuous operation due to the continuous heating of the current-carrying conductors and insufficient heat dissipation. This prolonged high-temperature operation leads to the continuous accumulation of heat within the enclosed cavity, creating a potential thermal effect that could compromise system safety.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a durable and long-lasting busbar trunking, comprising a busbar trunking body, wherein the busbar trunking body is connected to a top shell plate, the top shell plate is provided with an installation groove communicating with the interior of the busbar trunking body, and a heat sink is detachably connected to the top shell plate through the installation groove, wherein the bottom of the heat sink extends into the interior of the busbar trunking body and directly contacts the conductive ribbon cable.

[0005] Preferably, the bottom of the heat sink has several slots, the shape of which matches the cross-section of the conductive ribbon cable inside the busbar trunking, and the inner wall of the slot forms a snap-fit ​​heat dissipation contact with the conductive ribbon cable.

[0006] Preferably, the top side of the heat sink is provided with a connecting block, which is fixedly connected to the upper surface of the top shell plate by bolts.

[0021] like Figure 1-3 As shown, this utility model discloses a durable busbar trunking with a long service life, including a busbar trunking body 1. The busbar trunking body 1 is connected to a top shell plate 11. The top shell plate 11 has an installation groove 112 that communicates with the interior of the busbar trunking body 1. The top shell plate 11 is detachably connected to a heat sink 2 through the installation groove 112. The bottom of the heat sink 2 extends into the interior of the busbar trunking body 1 and is in direct contact with the conductive ribbon cable.

[0022] The bottom of the heat sink 2 has several slots 21. The shape of the slots 21 matches the cross-section of the conductive ribbon cable inside the busbar trunking 1. The inner wall of the slots 21 forms a snap-fit ​​heat dissipation contact with the conductive ribbon cable.

[0023] The heat sink 2 consists of two rectangular blocks of different sizes. The smaller rectangular block at the bottom matches the mounting slot 112 and is inserted into the mounting slot 112. The slot 21 is engaged with the internal conductive ribbon cable. The bottom surface of the larger rectangular block (the upper part of the heat sink) is attached to the upper surface of the top shell plate 11. Each slot 21 corresponds to a conductive ribbon cable in the busbar trunk body 1. The inner wall of the slot 21 forms a surface contact with the side of the conductive ribbon cable.

[0024] A connecting block 22 is provided on the top side of the heat sink 2. The connecting block 22 is fixedly connected to the upper surface of the top shell plate 11 by bolts.

[0025] The bolt passes through the connecting block 22 and connects to the pre-set threaded hole on the top shell plate 11.

[0026] The top surface of the heat sink 2 has several wavy protrusions to increase the heat dissipation area.

[0027] Among them, the wavy protrusions are arranged continuously along the top surface of the heat sink 2.

[0028] The outer surface of the bus trunking body 1 is coated with a waterproof coating 12, and the inner surface is coated with an anti-corrosion coating 13. The waterproof coating 12 is a polyurethane layer, and the anti-corrosion coating 13 is an epoxy resin layer.

[0029] The waterproof coating 12 covers the entire outer surface of the busbar trunking body 1, and the anti-corrosion coating 13 covers the entire inner surface of the busbar trunking body 1.

[0030] The top shell plate 11 is connected to the busbar trunking body 1 by connecting bolts 111, and a waterproof gasket 113 is attached to the contact surface between the top shell plate 11 and the busbar trunking body 1.

[0031] The waterproof gasket 113 is sandwiched between the connection contact surface of the top shell plate 11 and the busbar trunking body 1.

[0032] The working principle of this utility model is as follows: (Refer to...) Figure 1-3 In this embodiment, when the conductive cable heats up, the heat sink 2 can quickly absorb heat by contacting the cable through the slot 21 at the bottom. At the same time, the wavy protrusion on the top of the heat sink 2 can increase the heat dissipation area and accelerate heat dissipation. Under normal conditions, the waterproof coating 12 on the outside of the busbar trunking body 1 can block moisture, and the anti-corrosion coating 13 on the inside can prevent corrosion. The top shell plate 11 is fixed by the connecting bolts 111, and the contact surface is clamped with a waterproof gasket 113 to prevent water ingress. During maintenance or cleaning, the heat sink 2 can be removed by loosening the bolts on the connecting block 22 to expose the internal structure. The design of the heat sink 2 combined with the waterproof coating 12 and the anti-corrosion coating 13 can reduce the temperature rise and extend the service life of the busbar trunking.
