In the summer with frequent thunderstorms, outdoor solar street lights are really a big test, so be sure to take lightning protection measures for solar street lights to avoid damage caused by lightning attacks. So what are the lightning protection techniques for solar street lights? In response to this problem,we will give you a detailed introduction.
1. Lightning protection grounding: In order to prevent electrical equipment from being struck by lightning, ground lightning rods, lightning conductors, and lightning arresters. The grounding resistance should be less than 10Ω.
2. Zero connection: connect the metal shell, metal frame, etc. of electrical equipment to the neutral ground wire. The ground wire should be an insulated wire and use a whole wire. No joints are allowed in the middle.
3. Protective grounding: In order to prevent the safety of people and equipment from being endangered when the equipment leaks, all exposed conductive parts of electrical equipment are grounded through the grounding wire, and the grounding resistance should meet the requirements of the installation of the leakage protector.
4. The problem of the street lamp circuit: install a dedicated photovoltaic DC lightning protection device. The lightning protection device is mainly designed according to the power supply voltage. In the thunderstorm weather, the circuit of the solar street lamp will generate a surge voltage or a surge current due to electrostatic induction or electromagnetic induction, which will affect the solar street lamp equipment. In severe cases, the solar street lamp will also be struck by lightning. damage.
The above lightning protection techniques of solar street lights are shared here. Summer is the season of frequent thunderstorms, so the lightning protection work of solar street lights must be done in advance. Follow the above methods to effectively avoid solar street lights from lightning strikes. Unnecessary damage caused by the downfall.
