New Energy Integrated Photovoltaic Prefabricated Cabin MV&HV Transformers Cutting-Edge Distribution Equipment

YB-PRE/YBM(P)/ZGS11-Z.G New Energy Integrated Photovoltaic Prefabricated Cabin is a European-style Integrated Machine. The layout of the European all-in-one machine is similar to that of conventional European transformers. The entire machine casing is made of a container casing, including a transformer room, high-voltage room, communication power cabinet room, and inverter room. Each room is separated by partitions or corrugated boards, and the inverter and high and low voltage rooms are distributed on both sides of the transformer room, with an overall herringbone structure. The inverters are arranged in a mirror image, with a lower inlet wellhead set between the inverter passages, and the inverter side outlet connected to the low-voltage bushing on one side of the transformer through copper bars and soft connections. The transformer is usually a dry type transformer, equipped with a vacuum load switch and a fuse combination appliance. The vacuum load switch and fuse combination appliance are connected to the transformer room through high-voltage cables, and the communication power cabinet is similar to the American integrated machine. The heat dissipation method of transformers usually adopts natural air cooling or forced air cooling. The containerized shell is equipped with ventilation louvers, fan outlets, and fans for internal and external air circulation of the entire substation. The inverter room is equipped with fire emergency lights, fire detectors, explosion-proof lighting, and fire extinguishers.
