زه یو قوي باور لرم چې هرڅوک یې په اړه پوهیږي بریښنا rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see بریښنا rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of بریښنا rods. Now let us know with you who invented بریښنا rods, بریښنا rods and the efficacy of بریښنا rod installation standards. 1. Who invented the بریښنا rod. The invention of the بریښنا rod has a good effect on preventing buildings from being struck by بریښنا. Nowadays, there are more and more multi-storey buildings in life, and the use of بریښنا rods is also more common. As everyone knows, many friends do not know who invented the بریښنا rod. Who invented the بریښنا rod? American scientist Franklin invented the contemporary بریښنا rod. Franklin felt that بریښنا was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by بریښنا, 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 بریښنا 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 بریښنا was relatively poor, and Franklin was not injured. The invention of the بریښنا rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about بریښنا strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of بریښنا rod. To put it bluntly, we can understand that the بریښنا rod is a device that prevents بریښنا strikes in buildings. Many multi-storey buildings have بریښنا rods, but many friends do not know the basic principles of بریښنا rods and how to avoid بریښنا strikes in buildings. Traditional بریښنا protection can be divided into anti-shock بریښنا, anti-magnetic induction بریښنا and comprehensive بریښنا protection. The بریښنا protection grounding equipment for shock and بریښنا protection is generally composed of three parts, namely the بریښنا strip, the wire and the grounding body; the بریښنا protection strip is divided into بریښنا rod, بریښنا protection wire and بریښنا protection net. The basic principle of بریښنا protection with the بریښنا rod as the بریښنا strip is: the بریښنا 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 بریښنا 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 بریښنا safety channel, and then pour into the ground to achieve the actual effect of بریښنا protection. In essence, the بریښنا rod is a kind of بریښنا rod, which can cause the surrounding بریښنا, charge and discharge in advance, and transmit the بریښنا current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by بریښنا immediately. 3. Lightning rod installation standards. Lightning rods are used to prevent بریښنا strikes in buildings, so the installation and use of بریښنا rods should be very standardized. Only the installation and use of the بریښنا rod can fully exert the بریښنا protection effect, so the installation of the standard بریښنا 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 بریښنا rod. The بریښنا rod base is fixed on the pre-set prefabricated concrete base. The بریښنا rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The بریښنا 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.
