Urban Village Reconstruction Project in Haizhu District, Guangzhou

       In order to solve the problem of difficult electricity use in urban villages, Haihong Electric Co., Ltd. and Guangzhou Haizhu Power Supply Bureau carried out cooperation and research and development.Photovoltaic Intelligent Double-layer dual-transformer Substation. This innovative product has the advantages of compactness, intelligence, visualization, and low carbonization, and provides an optimal solution for connecting the "last mile" of electricity consumption in urban villages.
       The substation is located in the urban village of Guangzhou City. Due to the large flow of people and vehicles and the large number of pipelines, it is difficult to coordinate the pipeline construction. The distribution transformer in the original station area is overloaded, but there is a lack of land for the construction of power facilities. The original project plan is a double-layer power distribution room, equipped with two 800kVA dry transformers (length 10.88m x width 4.13m x height 7.5m, covering an area of about 44.93㎡). Due to the large area of the power room, it also blocks the sunlight of residents. was strongly hindered. Guangzhou Haizhu Bureau took the urban village as a demonstration site, combined with HAIHONG's innovative plan, and changed the project to adopt the world's first photovoltaic intelligent double-layer dual-transformer Substation (5.3 m long x 1.7 m wide x 2.9 m high, covering an area of 9 ㎡) , Compared with the double-layer electric house, the area is reduced by 80%, the height is reduced by 61%, and the civil construction investment is reduced by 90%, and the project plan has been unanimously approved.
