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