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