Lighting Protection For Building

There are many electrical systems inside the building, whether it is a direct lightning strike or an induced thunder, it will cause damage to these electrical systems inside the building. The traditional method tells us to unplug electrical equipment during thunder. However, much electrical equipment needs to operate continuously and can't be powered off. The installation of a suitable surge protector (lightning protection device) is an important building lightning protection measure. By deploying a three-level lightning protection system at the main power distribution cabinet, secondary power distribution cabinet, and important electrical equipment ends, the electrical equipment in the building can be well protected from lightning intrusion.

According to the lightning protection needs of the building power system, Shenzhen Techwin as a lightning protector supplier proposed a comprehensive lightning protection solution

As shown in the schematic diagram, the lightning protection box of the building’s power supply system is designed according to the four-level protection requirements

Lightning protection measures for the power supply system

1. The first-level lightning protection of the power supply: M100B+C/4 AC power lightning protection device is used and installed in the main power distribution box/cabinet of the building.

2. The second-level lightning protection of the power supply: M60B4 AC power lightning protection device is used, and it is installed in the distribution box/cabinet on each floor.

3. The third-level lightning protection of the power supply: M40B2 AC power lightning protection is used, and it is installed in the distribution box/cabinet of the computer room, office, etc.

4. The fourth-level lightning protection of the power supply: use MC10-220-6 or PDU10-220-6 power supply lightning protection sockets, installed in front of terminal equipment such as wall power outlets or switches.

Lightning protection measures for signal systems:

1. Install a multi-port integrated network signal lightning protection device D05J4-24 in the computer room switch

2. Install D05J4 network signal lightning protection device in front of the network equipment such as the network server of the computer room, the signal line entrance of the computer terminal, and the office computer.

In this way, through multi-level protection, we can discharge the lightning overvoltage that invades along the power line and the signal line to ensure the safety of buildings, equipment, and personnel.
