With the development of modern urban power grid, and the recommendation of the strategic goal of the State Grid Corporation of China to build a world energy Internet enterprise. The continuous increase in urban electricity consumption and the increasing scarcity of land resources have made the demand for miniaturization of distribution stations (rooms) and distribution equipment more urgent. The typical design revision work of State Grid Corporation of China's distribution network has added miniaturized switch station types, and after optimization, various types of switch stations can reduce the average land area by more than 60%. The ZMXB2 series of miniaturized intelligent prefabricated substations (hereinafter referred to as miniaturized box transformers) developed by our company have modular design, simple structure, minimal footprint, safety and reliability, no maintenance, low maintenance, compliance with environmental requirements, high degree of automation and standardization, and diverse appearance forms that can coordinate with the surrounding environment. Suitable for crowded roads and relatively narrow spaces in modern cities, and also in line with the standard requirements of State Grid Corporation of China's distribution network automation.
