Найзағайды кім ойлап тапты Найзағайдың қызметі Найзағайдың орнату техникалық талаптары

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