ABSTRACT

Because of the situation of the solar water heater systems, it is aiming at safety of the current of lightning protection from the hazards of them. From the structure and working principle of solar water heaters and the way of lightning introduction, the paper discussed the protection methods of direct lightning and inductive lightning, as well as shielding and equipotential bonding methods. These methods can effectively reduce and avoid the occurrence of lightning strikes, and provide a comprehensive lightning protection construction method for installing solar water heaters. According to the number of water heaters and the way of laying, the lightning rod or lightning protection belt can be flexibly used for protection. While using lightning rods or lightning protection belts for lightning protection, it is also necessary to consider equipotential bonding by means of lightning protection facilities of buildings. This can be easy to install and cost-effective. These methods can be considered, the safety hazards of solar water heaters can be effectively reduced.
