Кой е изобретил гръмоотвода. Функцията на гръмоотвода. Изискванията за монтажна спецификация на гръмоотвода

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