Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a low-voltage AC integrated power distribution box. Background Technology

[0002] As the core hub for power transmission and distribution, integrated distribution cabinets are widely used in industrial plants, commercial buildings, residential communities and other places. They undertake important functions such as power collection, distribution, protection and control. With the continuous expansion of the scale of modern power systems, the requirements of electrical equipment for power supply stability and reliability are increasing. The performance of integrated distribution cabinets directly affects the safe operation of the entire power system.

[0003] Integrated distribution cabinets installed outdoors or near large power equipment are frequently affected by natural environmental factors (such as strong winds and heavy rain) and vibrations generated by equipment operation. Traditional distribution cabinets lack effective vibration damping measures. When encountering strong winds, overhead conductors generate high-frequency vibrations, which are transmitted to the inside of the distribution cabinet through the incoming lines. This can lead to loose terminals, poor contact of electrical components, and ultimately, distribution cabinet malfunctions, seriously threatening the safe and stable operation of the power system. Therefore, there is an urgent need to design a low-voltage AC integrated distribution box to solve these problems. Utility Model Content
