| 1. Overview |
| The YB series prefabricated substation is a compact complete set of power distribution equipment that combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. It is used in urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mines and oil fields, and temporary construction power supply places to receive and distribute electric energy in the distribution system. The YB prefabricated substation has the characteristics of strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, the floor area of box- type substations with the same capacity is usually only 1/10~1/5 of that of conventional substations, which greatly reduces the design workload and construction workload, and reduces construction costs. In the distribution system, it can be used for ring network distribution systems, dual power supply or radiation terminal distribution systems, and is a new set of equipment for the construction and transformation of urban and rural substations. The YB prefabricated substation complies with the national standard GB/T17467- 1998 "High-voltage/Low-voltage Prefabricated Substation". |
