Which has the following advantages. (1) The high-voltage switch equipment, the transformer and the low-voltage distribution equipment are assembled and debugged in a factory in advance, the integrated design is realized, the protection functions of moisture resistance, rust resistance, dust resistance, fire resistance and the like are achieved, and the high-voltage switch equipment, the transformer and the low-voltage distribution equipment are connected through bus bars or cables, so that the high-voltage switch equipment, the transformer and the low-voltage distribution equipment have the characteristic of modularized combination. (2) The system has the advantages of small volume (the occupied area is only 1/5 of that of a traditional transformer substation), suitability for urban public facilities (such as street lamp power distribution), industrial parks, commercial centers and temporary construction scenes, and good flexibility and convenience. (3) The outdoor installation is supported, the rapid deployment and maintenance can be realized through the modular design, and the environmental adaptability is good. In summary, the preassembled transformer substation takes standardized and modularized design as a core advantage, and the flexibility and the safety of power supply are optimized through integrated and intelligent technologies, so that the preassembled transformer substation becomes an important alternative scheme of the traditional transformer substation.
