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