YBF-1210KV outdoor pre-installed street light box 35KV European box change
standard
The prefabricated substation meets the standards of SD320-1992 "Box-type substation technical conditions" and GB/T17467-1998 "High-voltage/low-voltage prefabricated substation".
Overview
European type box substation(MV/LV Prefabricated Substations) is also known as outdoor complete substation, also known as combined substation, because it has the advantages of flexible combination, easy transportation, migration, convenient installation, short construction period, low operating cost, small footprint, no pollution, maintenance -free, etc., Received wide attention. In rural power grid construction (reconstruction), it is widely used in the construction and transformation of 10~110kV small and medium-sized substations (distribution) substations, factories and mines, and mobile operation substations in urban and rural areas, because it is easy to penetrate into the load center and reduce the power supply radius., Improve the quality of terminal voltage, especially suitable for rural power grid transformation, known as the target mode of substation construction in the 21st century.
Features
1. Flexible combination mode. Because the structure of the European box substation is relatively compact, each box constitutes an independent system, which makes the combination mode flexible and changeable. European-style box substation; 35kV equipment can also be installed outdoors, 10kV equipment and control and protection system box installation, this combination method is especially suitable for the transformation of old substations in rural network transformation, that is, the original 35kV equipment does not move, only Install a 10kV switch box to meet the unattended requirements.
2. Low investment and quick results. European box substation (outdoor layout of 35kV equipment, installation in 10kV equipment box) is 40% less investment than integrated substation of the same scale (outdoor layout of 35kV equipment, 10kV equipment in indoor high voltage switch room and central control room) %~50%.
3. Small footprint
Function
It has the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box-type substations with the same capacity usually occupy only 1/10 of the area of conventional substations. ~1/5, which greatly reduces the design workload and construction volume, and reduces the construction cost. In the power distribution system, it can be used in the ring network power distribution system, and can also be used in the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations.
