AI Technical Summary
Existing distribution cabinets lack protective and impact-absorbing structures, making them prone to tipping over or deforming when hit by vehicles or people, which can cause the wiring of internal electrical components to be pulled, leading to safety accidents such as open circuits or leakage.
Protective plates are installed at the front and rear of the distribution cabinet, and a rotating buffer structure is set at the bottom, including a buffer disc and a reset spring. The impact force is reduced by rotating and displacing the buffer disc, and the horizontal reset spring provides additional cushioning during lateral impacts to prevent the cabinet from tipping over or deforming.
It effectively reduces the probability of damage to the distribution cabinet during collisions, protects the cabinet and internal electrical components, avoids circuit breakers or leakage accidents, improves impact resistance, and ensures the stable operation of the power system.
