Application of modular assembly technology in the standardized construction of distribution network

In the context of the transformation of distribution network projects towards efficiency and standardization, this paper, based on the systematic application of modular assembly technology, constructs a standardized construction system for distribution networks encompassing “functional unit division-parameter constraint system-interface coordination mechanism-digital process management.” Through the “functionallevel” two-dimensional method, the paper divides modules, unifies mechanical, electrical, and information interface standards, and establishes a multi-dimensional performance constraint model, realizing the refined management of the entire process from factory prefabrication to on-site assembly and full lifecycle data traceability. Practical application in a dual-ring distribution network project demonstrates that this technical system significantly outperforms in construction efficiency, quality stability, and standardization level, providing a replicable and scalable technical path and engineering model for distribution network construction.
