Description

Technical Field

[0001] This utility model relates to the field of switch box technology, specifically to a modularly combinable energy transfer switch box. Background Technology

[0002] Energy transfer switch boxes are important pieces of equipment widely used in power systems, primarily for the distribution, transfer, and protection of energy. They are typically installed in distribution networks or new energy access systems, undertaking the critical function of transmitting energy from upstream equipment to downstream loads, while also serving as a protection, management, and monitoring unit. Through their enclosure structure, energy transfer switch boxes provide a stable installation space and protective barrier for the internal electrical equipment, thereby ensuring the safe operation of the equipment in various environments. Their application areas cover municipal power grids, new energy power plants, energy storage systems, industrial power distribution, and temporary power supply scenarios.

[0003] Existing energy transfer switch boxes generally consist of a cabinet, a door, and internal equipment. The cabinet, as the main load-bearing structure, is typically fixed, including a one-piece molded structure or a welded fixed structure. This type of fixed cabinet is usually not disassembled after production and is transported, installed, and used as a single unit. While this design simplifies the manufacturing process and improves the cabinet's strength to some extent, it also exposes many problems, such as occupying a large amount of space during transportation, being easily damaged, and lacking flexibility in use.

[0004] Existing energy transfer switch boxes occupy a significant amount of space during transportation. Due to their fixed structure design, the boxes cannot be disassembled or folded, making it difficult to compress their volume during transport. This results in low utilization of transport vehicles and a limited number of switch boxes that can be carried in a single shipment, significantly increasing logistics costs. Furthermore, during long-distance or stacked transport, the fixed structure of the box is prone to deformation or even damage due to uneven stress or external pressure, affecting the normal operation of the equipment. Therefore, we propose a modular energy transfer switch box. Utility Model Content

[0005] The purpose of this invention is to provide a modularly combinable energy transfer switch box to solve the problems mentioned in the background art.
