    Photovoltaic power station to fight against storm Release time: 2017-11-09 In order to resist natural disasters, it is necessary to control the location, design and installation of photovoltaic power stations. After the completion of the construction of the power station, how to effectively prevent natural disasters, the role played by the later operation and maintenance can not be underestimated, the above steps can be described as interlocking and indispensable. Therefore, in the storm-prone area, the following four points should be done to build a distributed photovoltaic power station: I. Site selection: ensuring the quality of the building Any building must be designed with safety in mind. In the past, building materials were often heavy, and the design was mainly based on support capacity and prevention of earthquake risks. In recent years, with the advent of lightweight materials, the risk of these building materials being blown away by the wind is also considered in design, preventing the roof from being torn by the airflow. At present, household distributed photovoltaic power plants are mainly installed on inclined roofs and flat roofs. The flat roof covers concrete flat roof, color steel flat roof, steel flat roof, ball joint roof and so on. There are also some places to pay attention to the installation location of the PV power plant. It is necessary to consider the installation location, installation orientation, installation angle, load requirements, and arrangement and spacing. From this point of view, the location of the photovoltaic power station can not be determined by a single finger. Mounting components on a beveled roof Second, the design: improve the strength of the component, design the appropriate windshield From the perspective of component materials, the choice of component backplane, frame material, and package glass can be considered to improve the anti-impact and anti-seismic properties of the components for specific climate environments, thereby improving the ability to withstand special situations. From the perspective of power plant design, while weighing the cost of photovoltaic power station and power generation, the strength design requirements of photovoltaic supports and component clamps can be appropriately increased, and the inclination of components with better wind resistance can be reasonably selected. In addition, consider designing a suitable windshield. The wind deflector is fixedly mounted on the rear pillar of the bracket system, and the panel is provided with a plurality of air guiding ports, which have the functions of guiding the flow and reducing the wind pressure of the assembly. The beam of the bracket system is reduced in force, the pulling force of the foundation is reduced, and the safety factor of the photovoltaic power station structure is improved. However, the force on the rear pillar is increased, and the axial shear force of the foundation is increased. The foundation force is checked....
