Analysis of wind resistance and lightning protection of solar street lamps

   1. Wind resistance analysis of solar street light system

   In the solar street light system, one of the most important issues in the layout is the wind-resistant design. The wind resistance design is mainly divided into two parts, one is the wind resistance design of the battery module bracket, and the other is the wind resistance design of the light pole. Among them, the wind-resistant design of the components is particularly important. The specific analysis is as follows:

   According to the technical parameters of the battery module manufacturer, the upwind pressure that the solar battery module can withstand is 2400Pa. The wind resistance coefficient is 36m/s. According to the standard building layout load code 'GB50009-2001Therefore, the module itself can withstand the local wind speed without being damaged. The key to the design is the connection between the battery module bracket and the light pole.

   2. Analysis of lightning protection for solar street lights

  1. When the height of the street lamp pole is above 4.00 meters (including 4.00 meters), the flashing should be considered. It is not possible to use the street lamp glass cover as the air-termination device; the metal lamp cover can be operated as the air-termination device.

  2. When a metal light pole is used, the light pole itself can be directly operated as a lightning protection downline.

   3. When the basic steel cage of the street lamp is below -0.50 meters and the steel profile is greater than 0.37 square meters, it can be used as a lightning protection grounding body, otherwise an artificial grounding electrode should be added. The artificial vertical grounding electrode adopts hot-dip galvanized angle steel, and the specification of the vertical grounding electrode should be ∠5mm×50mm×50mm, and the length is 2.5m. It is required to reliably weld the artificial vertical grounding electrode and the steel cage of the fundamental lightning protection grounding body. The steel bars of the steel cage of the fundamental lightning protection grounding body should be welded to each other and reliably welded to the anchor bolts of the street lamp. The grounding resistance of street lights should not be greater than 10 ohms. If greater than 10 ohms, Jiangsu Naite Lighting Electric Co., Ltd. is engaged in the production and design of solar street lights and high-pole lights. It has 20 years of solar street light production experience to create the most professional solar energy. Street lamp manufacturer, contact number: 13805257308. , Artificial grounding body should be added to meet the requirements.

   3. Suggestions

   1. In order to minimize the wind resistance of solar panels, it is recommended that the total power of solar street lamp battery monolithic combined light panels produced by solar panel manufacturers afterwards does not exceed 60W.

   2. In order to prevent the solar panel from accidentally falling and hurting people, it is recommended that the solar panel manufacturer combine the solar panel into a circular panel, or change the corners of the square panel to a curved design.
