Description

Technical Field

[0001] The utility model belongs to the field of bus ducts, and in particular relates to a double-circuit lighting bus duct. Background Art

[0002] Traditional lighting power distribution systems typically rely on cables and cable ducts, which have certain limitations in terms of wiring complexity, installation flexibility, and maintenance convenience.

[0003] The bus duct has a better heat dissipation effect. Due to its flat shape, the heat dissipation surface area is larger, which helps to reduce the temperature. In contrast, the circular cross-section of the cable limits the heat dissipation surface area and easily leads to overheating. The bus duct has a large current carrying capacity. Under the same current carrying capacity, the bus duct can save 20%-35% of copper and reduce power loss by more than 15%, which is very important for high-power transmission systems. The service life of the bus duct is usually 2-3 times that of the cable. Some countries stipulate that the service life of the cable is 12-15 years, while the bus duct can be used for 30-50 years or even longer.

[0004] When using cables to build lighting power systems, the wiring can only be done point-to-point, which is cumbersome. This shortcoming is further magnified in large-scale lighting scenarios in industrial and commercial places. If the lighting point needs to be changed or there is a problem with the bus duct, the entire cable needs to be replaced, while the bus duct can be replaced in sections, which can reduce maintenance costs and power outage time.

[0005] Conventional lighting busbar systems are made of highly conductive copper or aluminum, typically enclosed in a metal casing. High-strength insulating materials (such as epoxy or polyethylene) are used to wrap the conductive conductors. Installation paths and distribution points are planned based on the building's power needs and layout. While lighting busbar systems are superior to traditional cable systems in many ways, they still have some issues and drawbacks:

[0006] 1. The installation space requirements are relatively high. The installation of the bus duct system requires a certain amount of space and has certain requirements on the internal structure of the building. Especially in the renovation of old buildings, there may be a problem of insufficient space;

[0007] 2. Limited flexibility. The general bus duct system requires detailed planning during the design and installation stages. If there are major adjustments in the later stage, it may need to be redesigned and installed, and the flexibility is relatively limited.

[0008] Therefore, a dual-circuit lighting bus duct is proposed to solve the above-mentioned drawbacks. Utility Model Content

[0009] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dual-circuit lighting bus duct.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0011] A dual-circuit lighting bus duct comprises a plurality of aluminum alloy shells, a plurality of plug connectors and a plurality of connectors, wherein the connectors are connected between two adjacent aluminum alloy shells, and two sets of bus duct circuits are enclosed in the aluminum alloy shells;

[0012] The bus duct loop includes a first busbar insulation clamp, which is wrapped with an insulation layer, and a four-wire copper conductor is wrapped in the insulation layer. Multiple plug interfaces corresponding to the two groups of bus duct loops are provided on both sides of the aluminum alloy shell, and multiple copper busbar slots are provided on the side of the plug interface. Copper busbar pins for connecting to the plug interface are provided on the side of the plug connector.

[0013] Optionally, serrated heat dissipation teeth are provided on the four sides of the aluminum alloy shell to improve the heat dissipation capacity of the dual-circuit lighting bus duct.

[0014] Optionally, a foolproof positioning slot is provided on the side of the plug interface, and a foolproof plug that is compatible with the foolproof positioning slot is provided on the side of the plug connector.

[0015] Optionally, both sides of the plug connector are provided with clamping claws for clamping the aluminum alloy shell, and an outlet is provided at the end of the plug connector.

[0016] Optionally, the connector includes a second busbar insulation clamp, the second busbar insulation clamp is wrapped with a clamping connection copper sheet, and the aluminum alloy shell and both ends of the two sets of busbar duct loops are designed with male connectors.

[0017] Optionally, the aluminum alloy shell is made of aluminum-magnesium alloy material, and the surface of the aluminum alloy shell is treated with epoxy resin electrostatic powder spraying.

[0018] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0019] 1. The dual-circuit lighting bus duct can be installed quickly and uses plug-in units to quickly and flexibly redistribute the load. When a major technical transformation is carried out, the bus duct system can be easily disassembled and the bus duct length can be easily adjusted according to the needs of the new occasion;

[0020] 2. A single plug connector can provide lighting power for three circuits, which makes it very convenient to add, move, and replace electrical equipment without cutting off the main power supply;

[0021] 3. There are two loop conductors in a single bus duct, which only increases the cross-sectional area to achieve the power supply effect of two lighting bus ducts, doubles the plug points, and optimizes the bus duct space utilization;

[0022] 4. The load is closer to the power supply;

[0023] 5. The bus duct shell is integrally formed of metal plates, and the joints also have good load-bearing capacity.
