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