Description

Technical Field

[0001] This invention relates to the field of connection device technology, specifically a modular busbar trunking that can provide emergency fire protection. Background Technology

[0002] Busbar trunking, as a crucial component of modern power transmission and distribution systems, is widely used in industrial plants, high-rise buildings, large commercial facilities, and data centers. With its advantages of large transmission capacity, compact structure, and convenient installation, it has gradually replaced traditional cable cabling, becoming the mainstream solution for power distribution systems. As electrical loads increase and the demand for intelligent equipment grows, the safety, reliability, and ease of maintenance of busbar trunking are becoming important directions for industry development. In particular, its functions in fire safety, disaster prevention and early warning, and emergency isolation have become a hot topic in the current technological field, possessing broad development prospects and market demand.

[0003] Currently, most existing busbar structures use copper busbars placed directly inside insulating supports, and complete basic electrical transmission functions through simple outer casing sealing protection. There are also some technical means for safety protection, such as adding basic insulation layers and simple smoke alarm detectors. However, these technical means often only have a single function, and the safety protection methods are relatively passive. They cannot effectively deal with sudden fires or faults that break out instantly, and they also lack automatic response capabilities and active protection measures.

[0004] Existing technologies have significant shortcomings. First, traditional busbar trunking lacks an active fire monitoring and rapid response protection system. When abnormal temperature rise or smoke / gas anomalies occur inside the busbar trunking, it cannot quickly and accurately provide early warning, actively isolate, or rapidly extinguish the fire, which can easily lead to the further expansion of fire hazards. Second, existing busbar trunking lacks modular quick-connect functionality, resulting in low installation and maintenance efficiency. Finally, the flexible angle adjustment design affects the convenience, maintainability, and stability in practical applications. Therefore, those skilled in the art have provided a modular busbar trunking that can provide emergency fire isolation to solve the problems mentioned above. Summary of the Invention

[0055] Working principle of the invention:

[0056] The busbar trunking body mechanism 1 achieves a robust support structure. The upper cover plate 11, side wall plate 12, bottom plate 13 and insulating support block 15 are tightly fixed together to form a closed and robust installation space. The copper busbar 14 is reliably insulated under the effective isolation of the insulating support block 15, and the efficient transmission of electrical energy is achieved through the modular docking mechanism 2. The modular docking mechanism 2 relies on the coordinated work of the snap-fit ​​component 21, the rotating component 23, and the transmission component 22 to quickly dock the busbar trunking. The snap-fit ​​component 21 is inserted into the snap-fit ​​bracket 214 through the plug-in block 212, and achieves reliable fixing and automatic return functions through the snap-fit ​​elastic element 213 and the disconnect elastic element 215.

The photoelectric smoke sensor 43 can quickly capture smoke particle information, and the gas sampling tube 44 continuously samples and analyzes the air composition. The three work together to provide early warning and prevent fires. The emergency isolation mechanism 3 is securely connected to the insulating support block 15, upper cover plate 11, side wall plate 12, and bottom plate 13 via the heat insulation pad 31, forming a highly efficient heat insulation and fireproof system. The first flame retardant box 33 stores trimethyl phosphate, which is precisely controlled by the proportional valve 32 and delivered to the spray head 35 through the internal pipe of the side wall plate 12.
