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