Abstract: The construction period of rural low-voltage distribution room is short and the task is large. The uneven quality of manpower construction has seriously affected the safety, reliability and stability of the distribution room. The research starts from the prefabricated structure and designs the low-voltage intelligent distribution room suitable for the construction of the new rural area of China Southern Power Grid. On the basis of steel structure assembly and concrete pouring, the low-voltage distribution room unit module is formed. Through the prefabrication and splicing process, gradually assemble, install and fix to maximize the construction efficiency and reduce the impact on the surrounding environment.
