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