The YB preinstalled substation is composed of the high-voltage switchgear, low-voltage distribution panel, distribution transformer and enclosure. The high-voltage switchgear adopts air load switch and the transformer is dry-type or oil immersed type. The substation adopts good ventilation structure with elegant appearance and good heat-insulating performance. The temperature rise of the compartments caused by the outdoor solar radiation can be reduced to within the lowest limits on account of the upper and lower ventilation windows. The forced ventilation device and the temperature auto-controlled device should be installed in the substation. The systems of control, protection, live display and the lighting are equipped in each separate unit.
This substation fulfills the functions such as transformation of energy, distribution, transmission, metering, compensation, system control, protection and communication.
1.Advanced technology, safe and reliable
The box body adopts domestic leading technology and craftsmanship. The outer shell is generally made of galvanized steel plate. The frame adopts standard container materials and manufacturing techniques. It has good anti-corrosion performance and guarantees no corrosion for 20 years. and can ensure normal operation in the harsh environment of -40℃～+40℃.
2.High degree of automation
The whole station is intelligently designed. The protection system adopts the integrated automatic device of the substation and is installed in a decentralized manner.
All equipment is installed and qualified in the factory at one time, which shortens the design and manufacturing cycle.The entire substation takes about 5-8 days from installation to commissioning.
Due to the compact structure of the European-style box change, each box constitutes an independent system, which makes the combination flexible and changeable.
5.Low investment and quick results
European-style box substation, compared with the same scale integrated substation, reduces investment by 40%-50%.
6.Cover small space.
If a box-type substation is selected, the minimum area of the main transformer box and the switch box can be as small as 100m, It can be installed and put into production by making full use of the center of the street, the square and the corner of the factory
The box shell adopts aluminum-zinc steel plate and container manufacturing technology. The appearance design is beautiful. Under the premise of ensuring the reliability of power supply, by choosing the shell color of the box-type substation, it is easy to coordinate with the surrounding environment. It is especially suitable for urban construction.
