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