In summer, when thunderstorms are frequent, outdoor solar street lights face significant challenges. Therefore, it is essential to implement lightning protection measures for solar street lights to prevent damage from lightning strikes. What are the lightning protection techniques for solar street lights? In response to this question, we will provide a detailed introduction.
1. Lightning grounded: To prevent electrical equipment from being struck by lightning, grounding devices such as lightning rods, lightning wires, and lightning protectors should be grounded, with grounding resistance less than 10Ω.
2. Zero connection: Connect the metal shell and metal frame of the electrical equipment to the neutral grounding line. The grounding wire should use insulated wire and should be a continuous line without joints.
3. Protective grounding: To prevent the risk of electric leakage threatening personal and equipment safety, all exposed conductive parts of electrical equipment should be grounded through a grounding wire, and the grounding resistance should meet the installation action requirements of the leakage protector.
4. Issues with streetlight circuits: Install dedicated photovoltaic DC lightning protectors. Lightning protectors are designed based on the power supply voltage. During thunderstorms, the solar street light circuit can experience surge voltage or surge current due to static electricity or electromagnetic induction, which may affect the solar street light equipment. In severe cases, the solar street lights may suffer damage from lightning strikes.
The above lightning protection techniques for solar street lights have been shared here. Summer is the season of frequent thunderstorms, so it is crucial to implement lightning protection measures for solar street lights in advance. By following the methods outlined above, unnecessary damage under lightning strikes can be effectively avoided.
