In the summer with frequent thunderstorms, it is really a big test for outdoor solar street lights, so it is necessary to take lightning protection measures for solar street lights to avoid being harmed by lightning strikes. So what are the lightning protection techniques for solar street lights? In response to this issue, the editor of Century Sunshine Lighting will introduce it to you in detail.
1. Lightning protection grounding: In order to prevent electrical equipment from being struck by lightning, lightning protection devices such as lightning rods, lightning conductors and lightning arresters should be grounded, and the grounding resistance should be less than 10Ω.
2. Zero connection: Connect the metal casing, metal frame, etc. of the electrical equipment to the neutral ground wire. The grounding wire should be an insulated wire and use a whole wire without joints in the middle.
3. Protective grounding: In order to prevent the safety of people and equipment from being endangered when the equipment leaks electricity, all exposed conductive parts of electrical equipment are grounded through grounding wires, and the grounding resistance should meet the requirements for the installation of leakage protectors.
4. Problems with street light circuits: Install a dedicated photovoltaic DC lightning arrester. Lightning arresters are mainly designed based on power supply voltage. In thunderstorm weather, the circuit of solar street lights will generate surge voltage or surge current due to electrostatic induction or electromagnetic induction, which will affect the solar street light equipment. In severe cases, solar street lights will be damaged by lightning strikes.
The above lightning protection tips for solar street lights are shared here. Summer is a season with frequent thunderstorms, so the lightning protection work of solar street lights must be done in advance. According to the above methods, it can effectively avoid unnecessary damage to solar street lights caused by lightning strikes.
