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