Lightning protection measures for electrical and electronic equipment are indispensable

Lightning strikes are a type of severe meteorological disaster that is often overlooked. In real life, the probability that each of us is struck by lightning is very low, and we can basically ignore it. However, there are many situations in which lightning is encountered as a weather phenomenon. Globally, the frequency of thunder and lightning is very high. There are hundreds of lightnings per second; there are more than 8 million lightnings per day; more than 3 billion lightning strikes occur in an average year; and indirect deaths are caused by lightning strikes. There are tens of thousands of people. At the end of the 20th century, the UN Organization’s International Decade for Disaster Reduction activities listed lightning disasters as one of the ten most serious natural disasters.

China is a region where frequent lightning storms occur. There are 21 provincial capital cities where thunderstorm days last for more than 50 days, up to 134 days. The number of lightning disasters that occur every year is nearly 10,000 times, resulting in 3,000 to 4,000 person-to-person casualties and direct economic losses ranging from billions to billions.

Indirect lightning strikes are more extensive and serious than direct lightning strikes.

The direct lightning strike is destructive, but the probability is very low, and the harm of indirect lightning strikes is more extensive and more serious. Direct lightning is a rapid discharge that occurs between a charged cloud layer (thundercloud) and a building, other objects, the earth, or a lightning protection device, and is accompanied by a series of destructive effects such as electric, thermal or mechanical forces. The main damage to buildings, buildings, electronic equipment and people. The voltage spike of direct lightning strikes can reach tens of thousands of volts or even several million volts. The peak current can reach several tens to several hundred kau, which is very destructive.

Indirect lightning refers to all the objects on the ground when the cloud strikes, especially the conductor. Because of the electrostatic induction, a large number of binding charges with the opposite polarity of the lightning are gathered in the thundercloud to the ground or to another thundercloud. After the flash discharge, the charge in the cloud becomes a free charge, resulting in a high electrostatic voltage (induction voltage). The overvoltage amplitude can reach tens to hundreds of thousands of volts. This overvoltage will often cause construction. The wires in the object, the metal conductors with poor grounding and the discharge of large metal devices cause electric sparks, which can cause fires, explosions, endangering personal safety, or damage to the power supply system.

Lightning equipment you choose right?

In today's society, with the continuous increase of buildings, the rapid growth of high buildings, and the high requirements for current stability of electrical and electronic equipment, the lightning protection of buildings, communication base stations, factories and mines, and electrical and electronic equipment cannot be ignored. Different circumstances in the selection of lightning protection equipment is also different, in this case, Shenzhen Xinsheng Sheng Technology Co., Ltd.'s small umbrella lightning protection for the lightning market needs, to provide users with professional lightning protection equipment and provide professional lightning protection solution.

For direct lightning protection, lightning rods, lightning protection strips, lightning conductors, lightning protection nets, or metal objects are usually used as lightning receptors to receive lightning currents and guide them through buried metal conductors to the ground. Scattered grounding devices are then dispersed into the ground. Among them, direct lightning protection for different buildings includes ordinary lightning rods, optimized lightning rods, early discharge lightning rods, and current limiting lightning rods. In the lightning protection grounding project, the necessary steels and long-lasting anti-corrosion resistance reducers can be added to increase the resistance of the ground. Values, effectively divert currents that are introduced into the ground.

The protection against indirect lightning strikes can be subdivided into power supply lightning protection and signal lightning protection. The power supply lightning protection includes three levels of power supply lightning protection. It can be based on the distribution situation of the building and the specific conditions of the electrical and electronic equipment on the current. Different levels of power supply lightning protection, specifically related to lightning protection equipment, single-phase power supply lightning protection module, three-phase power supply lightning protection, 48V power supply lightning protection module, 690V power supply lightning protection module, 1000V power supply lightning protection module applied to photovoltaic power generation and Three-phase power supply lightning protection module applied to direct current. Signal lightning protection equipment can be subdivided into computer network lightning protection devices, control signal lightning protection devices, video signal lightning protection devices, audio signal lightning protection devices, and antenna feeder lightning protection devices according to specific application conditions. According to different conditions of specific electrical and electronic equipment, rack-mounted computer network lightning protection, control signal lightning protection devices and video signal lightning protection devices can also be used. Of course, under actual conditions, it is also possible to combine and match different lightning protection requirements, including two-in-one lightning arrester and three-in-one lightning arrester.

Lightning protection, efficient protection of life and property

In the face of such severe lightning damage, the development of a lightning protection market is not only a need to ensure the safety of people’s lives and property, but also an inevitable requirement for economic construction and social development. The strength of the lightning disaster prevention capability is related to the issue of social public safety and concerns the improvement of the city’s overall competitiveness. No matter whether it is a government agency, or a high-rise building or related electrical and electronic equipment company, it must carry out effective lightning protection and choose its own high-quality lightning protection equipment according to its own specific conditions.
