In order to protect various types of equipment in buildings and buildings from lightning damage or minimize lightning damage, integrated lightning protection is now adopted. The comprehensive lightning protection design plan should include two aspects: the protection against direct lightning strikes and the protection against induced lightning strikes. The lack of any aspect is incomplete, flawed and potentially dangerous.
1. Lightning strike lightning protection mainly uses lightning rods, nets, belts and good grounding systems. Its purpose is to protect buildings from lightning damage and provide a relatively safe environment for people or equipment in buildings.
This part of the general substation has been built at the time of construction and usually does not need to be considered.
2. Induction of lightning protection Currently, there are two main ways for lightning-induced high voltage damage to communication equipment:
Radiated induced lightning strikes are strong lightning electromagnetic fields that cause equipment damage through radiation or induction.
Induced lightning high voltage pulses transmitted from various lines by power supply lines, signal lines, and control lines damage the electronic devices.
Therefore, the corresponding measures taken are:
· Take electromagnetic shielding measures.
Install surge protectors, including power supply systems and signal systems.
· Equipotential processing.
Good grounding.
