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