أنا من أشد المؤمنين بأن الجميع يعرف عنها برق rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see برق rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of برق rods. Now let us know with you who invented برق rods, برق rods and the efficacy of برق rod installation standards. 1. Who invented the برق rod. The invention of the برق rod has a good effect on preventing buildings from being struck by برق. Nowadays, there are more and more multi-storey buildings in life, and the use of برق rods is also more common. As everyone knows, many friends do not know who invented the برق rod. Who invented the برق rod? American scientist Franklin invented the contemporary برق rod. Franklin felt that برق was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by برق, he placed a paper kite tied with a long wire into a cumulonimbus cloud and placed it on the end of the wire. A bunch of silver keys. When the برق struck, Franklin's hand came close to the key, and a string of spark discharges erupted from the key. There is a real discomfort in the hand. Fortunately, the برق was relatively poor, and Franklin was not injured. The invention of the برق rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about برق strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of برق rod. To put it bluntly, we can understand that the برق rod is a device that prevents برق strikes in buildings. Many multi-storey buildings have برق rods, but many friends do not know the basic principles of برق rods and how to avoid برق strikes in buildings. Traditional برق protection can be divided into anti-shock برق, anti-magnetic induction برق and comprehensive برق protection. The برق protection grounding equipment for shock and برق protection is generally composed of three parts, namely the برق strip, the wire and the grounding body; the برق protection strip is divided into برق rod, برق protection wire and برق protection net. The basic principle of برق protection with the برق rod as the برق strip is: the برق rod is connected to the ground according to the transmission line, and has an equal phase difference with the floor, making full use of the relative height to increase the magnetic field strength to the specified value. correctly guide the charge and discharge. The برق rod causes electrostatic induction under the action of a strong electrostatic field, leading to upward charging and discharging; the two move forward to generate a برق safety channel, and then pour into the ground to achieve the actual effect of برق protection. In essence, the برق rod is a kind of برق rod, which can cause the surrounding برق, charge and discharge in advance, and transmit the برق current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by برق immediately. 3. Lightning rod installation standards. Lightning rods are used to prevent برق strikes in buildings, so the installation and use of برق rods should be very standardized. Only the installation and use of the برق rod can fully exert the برق protection effect, so the installation of the standard برق rod is very important. 1. The concrete base should be poured concrete at the installation site in advance, with a size of 400mm × 400mm × 600mm (length X width X height), and pre-embedded anchor screws or plastic expansion screws. 2. Install the برق rod. The برق rod base is fixed on the pre-set prefabricated concrete base. The برق rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The برق rod wire connector must be reliably connected with the power grounding wire, the wire connector is light green, and the cross-section BVR25mm2 or more copper core wire.
