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