Description

Technical Field

[0001] This utility model relates to the technical field of transformer frames, specifically to a modular box-type transformer frame. Background Technology

[0002] As a core piece of equipment in power systems, the frame structure of box-type transformers directly affects the installation efficiency, maintenance convenience, and operational reliability of the equipment. Traditional box-type transformer frames often adopt an integrated welded structure, fixing the top cover, base, and frame together through welding. This design has significant drawbacks in practical applications: First, the welding process requires high precision, and welding deformation or weld quality issues can easily lead to insufficient structural strength, affecting the long-term stability of the equipment; second, the integral structure is bulky, requiring large hoisting equipment for transportation and on-site installation, resulting in high construction costs and poor flexibility; furthermore, if local components (such as ventilation panels, cable fixing devices, etc.) are damaged or require functional upgrades, the entire unit often needs to be replaced or returned to the factory for repair, leading to low maintenance efficiency and significant resource waste.

[0003] Therefore, there is an urgent need for a highly modular and standardized box-type transformer frame that can replace the traditional welding process with a fully assembled structure, enabling rapid disassembly and assembly, flexible configuration, and low-cost maintenance, thereby fundamentally solving the problems of poor structural rigidity, difficult transportation and installation, and insufficient functional expandability in existing technologies.

[0004] Therefore, the existing technology still needs further development. Utility Model Content
