Description

Technical Field

[0001] This utility model relates to the field of armored switch technology, specifically to an armored withdrawable AC metal-enclosed switchgear. Background Technology

[0002] Armored withdrawable AC metal-enclosed switchgear is one of the important pieces of equipment in current power transmission and transformation systems. Currently, most armored withdrawable AC metal-enclosed switchgear can only be transported by overhead cranes. However, since overhead cranes are mostly used for localized lifting, in areas without them, the switchgear must be lifted onto pallets and then transported by forklifts in those areas. A search revealed that patent application number 201821637795.7 discloses an armored withdrawable AC metal-enclosed switchgear. This application solves the problem that during transportation, the armored withdrawable AC metal-enclosed switchgear requires a crane to lift it onto a pallet before using a forklift for transport, resulting in unstable transport and a tendency to tip over. The key technical feature is that the armored withdrawable AC metal-enclosed switchgear includes a main body. The bottom of the main body has symmetrical slots along its length for forklift insertion, with the slots perpendicularly penetrating the bottom of the main body. This design allows for stable transport using a forklift. The aforementioned application documents describe a forklift driving and moving the equipment by setting up a built-in slot. However, this structural design has significant drawbacks: firstly, the layout of the built-in slot occupies a large amount of internal space, resulting in extremely limited internal wiring space. This not only increases the difficulty of wiring construction but also hinders the rational planning and maintenance of the equipment's internal wiring. Secondly, this driving and moving method is only applicable to scenarios involving long-distance equipment displacement. In situations requiring small-scale fine adjustments or short-distance movements, the structural limitations of the built-in slot result in poor operational flexibility and difficulty in achieving precise control, greatly restricting the equipment's performance in complex application scenarios.

[0003] Therefore, we propose an armored withdrawable AC metal-enclosed switchgear. Utility Model Content
