Scope
Main technical content: This guideline applies to the rectification and construction of lightning protection devices for existing buildings in schools and kindergartens within the administrative area of Zhongshan City. The rectification and construction of lightning protection devices for other existing buildings can be used as a reference. The main technical content includes: 1) General provisions. General construction requirements for direct lightning strikes, the division of lightning protection zones, and grounding provisions. 2) Direct lightning protection. Measures such as lightning arresters, down conductors, grounding devices, protection against step and contact voltages, and safety distances. It clarifies the layout of dedicated down conductors and the construction requirements for dedicated grounding networks, and provides detailed construction instructions for the protection against contact and step voltages of dedicated down conductors. 3) Protection against lightning electromagnetic pulses. Measures such as equipotential bonding, shielding grounding, and surge protection devices (SPDs). It clarifies the installation requirements for power distribution systems and information systems, as well as the parameter requirements for SPDs in power supply lines.
