With the in-depth development of reform and opening up, people's living standards continue to improve, and the role of lightning arresters in extremely small industries is becoming more and more prominent. Next, Xiaobian and everyone talk about the details of the electromagnetic lightning protection method.
The building passes through the main reinforcement of the building, the upper end is connected with the lightning receptor, the lower end is connected with the ground net, and the middle is connected with the equalizing pressure net or the annular pressure equalizing belt of each layer to carry out equal pressure equipotential bonding for various metal pipelines entering the building. Equipotential treatment is performed on various ground lines with special requirements.
Requirements for wiring and grounding of computer communication network systems in building buildings: Communication cables and grounding cables should be concentrated in the middle of the building. Communication cable trunking and grounding trunking should be placed as close as possible to the building pillars or beams and kept at a long distance. The communication cable trunking and grounding trunking should be designed as far as possible from the building. The position where the column or beam is far away.
According to the division requirements of the 2-in-1 lightning protection zone, the exterior of the building is a direct lightning strike zone; the interior of the building and the computer room are in a non-exposed zone, and the more internal, the lower the degree of danger. The interface of the protected area is formed by an external lightning protection system, a reinforced concrete of a building, and a metal casing. Metal components such as electrical passages and metal pipes must be equipotentially connected at each passing point when passing through all levels of lightning protection.
According to the electromagnetic pulse protection standard of the power supply lightning protection device, the power supply type SPD and the communication network type SPD are installed. SPD is an effective means to protect electronic equipment from conductive surges and voltages caused by lightning strikes and other disturbances.
In short, the above-mentioned four points of the electromagnetic lightning protection method, we must be very familiar with and grasp the relevant information, in order to better promote the rapid development of the industry.
