Regarding the lightning protection of solar street lights, for the same location, it has a direct relationship with the selection ratio of solar battery components and batteries, and the guarantee time of solar street lights in continuous rainy days can be designed according to the specific use environment and customer requirements. In the design of solar street lights, down-conductors and ground networks must be installed. These systems constitute an external lightning protection system to prevent fire and personal safety accidents caused by direct lightning strikes on LED street lights. Set voltage protection to protect the equipment. Solar street lights have the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, energy saving and environmental protection, economical and practical.

How to achieve lightning protection for rainy solar street lights

One: The grounding of solar street lights is the most important. It is only necessary to use a pole body to release the fluid. The ground network is determined according to the geological soil.


2: In order to prevent endangering the safety of people and equipment when the equipment is leaking, all exposed conductive parts of electrical equipment are grounded through the grounding wire. The grounding resistance should meet the requirements of the installation of the leakage protector.


3: Connect to zero: metal frame is connected to neutral ground. , The ground wire should be insulated wire and use the whole wire, no joints are allowed in the middle. The shortest distance to the grounding wire of the arrester should be selected. The phase cross-sectional area S of the protection device is ≤16mm2.


Four: In the production design of street lamps, etc., the street lighting power supply lightning protection system has been subjected to strict testing for a long time before being applied to the product lamps, so as to ensure that the safety and life of the street lamps are consistent.


Five: internal and external lightning protection, internal lightning protection refers to the internal protection of the solar street light by grounding, setting voltage protection, etc., external lightning protection can avoid the disaster caused by DC lightning and casualties. Set a lightning protection module and an overvoltage protection module to reduce the potential difference between the interfaces of the device.
