Grounding at a private booth: systems, diagrams, photos, videos
The exploitation of current used and computer equipment without grounding can lead to failure. In a significant part of our country, especially near the rural area, there is an old power transmission system. They do not have the presence of a good grounding, otherwise the stench is rebuying at such a station, which simply does not satisfy the power of the electrical safety. To that, the Vlasniks must be robbed by themselves of grounding a private booth in a dacha.
What's wrong
Zahisne grounding is necessary for the provision of electrical safety in the booth. That's right, Vikonans, having appeared a strum turn in the vede to a negain spratsovuvannya ELV (shkodzhennya electrical insulation, or with a dotik to stremoved parts). Tse smut and main tasks of the system.
Another function of grounding is to ensure normal operation and electrical control. For some kind of electrical appliances, the presence of an arrogant dart in a rosette (likely є) is not enough. Necessary connection to the ground bus without a middle. For whom, ring є special zatiskachі on the case. If you talk about the pobutovu tehnіku, then tse mikrokhvilova pіch, oven and pryna machine.
The main task of grounding - to ensure the electrical safety of a frequent booth
Few people know that ale mikrohvilova pich without a direct connection to the "earth" for an hour of work can be sound, the reception of a vibromination can be unsafe for life. For some models, you can use a special terminal on the back wall, if you want to say only one phrase in the instructions: “grounding is necessary” without clarification, as it is the very best to install.
When dotik with wet hands to the body of the machine, you often feel tingling. It's safe, but it's unacceptable. You can get in touch by connecting the "ground" directly to the hull. In the case of the oven, the situation is similar. You don’t “pinch” it out, it’s a direct connection, it’s safer, the wires in the middle of the installation work in the most important minds.
From the computers on the right, there is still a cic. Having connected without intermediary "earthing" wires to the hull, you can in some time increase the speed of the work of the Internet and bring the number of "hangs" to a minimum. The axis is so simple through the appearance of a direct connection from the ground bus.
You need grounding at the dacha or in a wooden booth
In the countryside villages, earthing is required for obov'yazkovo. Especially yakscho budinok z palny material - wood or frame. To the right of thunderstorms. In the dachas there are a lot of elements that attract sparkles. All wells, sverdloviny, pipelines, which lie on the surface, or are buried on the minimum depth. Usі qі ob'єkti attract bliskavki.
As a thunderbolt, that grounding is not possible, the glimmering of the glare may be more equal to the fire. There is no fire nearby, so the fire will expand even more quickly. Therefore, in a pair of groundings, work a bliskavkovidvid - even a pair of sheared meter long, attached to a conic and connected for an additional steel rod from groundings.
Grounding systems for a private booth
There are six systems, but in individual forgetfulness, there are mainly only two: TN-S-C and TT. In the rest of the years, the TN-S-C system is recommended. In this scheme, the neutral at the substation is dead-earthed, and it has direct contact with the ground. Prior to respawning ground (PE), that neutral/zero (N) is conducted by one conductor (PEN), and at the entrance to the booth it is again divided into two conductors.
For such a system, a sufficient amount of money will be secured by machine guns (ELVs are not obov'yazkovy). Nedolik - in case of fire or damage to the PEN dart on the station between the booth and the substation on the earthen bus, the phase voltage is shown in the booth, as it does not vibrate with anything. Therefore, PUE visuvaє zhorstki vomogi to such a line: there may be a binding mechanical protection of the PEN dart, as well as a periodic backup grounding on the stovpakh through 200 m or 100 m.
Prote, a lot of power lines in the countryside are not satisfying to their minds. It is recommended to vicorate TT in this vipad. Thus, the scheme is guilty of victoriousness in the okremikh vіdkritih gospodarska pribudov іz earthen pіdlogu. They have a risk of touching one hour to the ground and the ground, which can be unsafe with a TN-S-C system.
The difference lies in the fact that the “earthing” is on the shield in the direction of an individual grounding circuit, and not in the form of a transformer substation, like in the front circuit. Such a system of stіyka up to a little bit of a draught, but it will also require an ELV installation. Without them, there is no defense against electric shock. To this, the PUE is more likely to be reserved, as the obvious line does not support the TN-S-C system.
Vashtuvannya grounding of a private booth
The deyakі old lines of power transmission vzagalі not mayut zahisnoy grounding. All the stench is guilty of changing, but if it happens, feed it. Since you have such a temper, it is necessary to build an okremy contour. Option two - to ground yourself at a private booth or at the dacha on your own, with your own hands, to trust the campaign. The service of the campaign is expensive, but it’s also an important plus: in the process of operation, to blame problems caused by improper functioning of the grounding system, the campaign has been hit hard, as the installation failed (may be written in the contract, read carefully). At the time of an independent vikonanny, everything is on you.
The grounding system of a private booth is being built with:
- grounding pins,
- metal smoogs, which should be combined into one system;
- lines to the ground loop up to .
Why do earthworkers work
As pins, it is possible to vicorist a metal rod with a diameter of 16 mm and more. Moreover, it is impossible to take the armature: its surface is fried, which changes the struma. So the burning ball near the earth is more likely to collapse. Another option is a metal wrap with 50 mm strips. These materials are good, because they can be hammered into soft ground with a sledgehammer. So that it would be easier to work, to build one kinet, to weld a maidanchik on the other, which is easier to beat.
Sometimes vikoristovuyut metal pipes, one edge of some flattening (brewing) at the cone. At the lower part (close to the distance from the edge) drill open. When drying up the soil, the struma rose significantly, and so it is possible to fill the stria with salty roses, inspiring the work of grounding. The minus of this method is to bring under the skin shearing of the digging / drilling of the Sverdlovin - to hammer them with a sledgehammer for the required clay not to go.
Depth of driving pins
Stir-earthing lines are due to go into the ground below the depth of freezing as at least 60-100 cm. To this end, the main tufts or the rod are 2-3 m long.
Why can't work
The work of a zahisnogo grounding is helping in the fact that it spreads along the great square of the stream of a turn. Vіdbuvaєtsya tse for rahunok schіlnogo kontakt metalevyh zemlyuvachiv - shtirіv and smoog - іz ґruntom. Tom Grounding elements are by no means farbuyut. It also greatly reduces the strum conductivity between metal and earth, and the shield becomes ineffective. To protect against corrosion in the areas of storage, you can use anti-corrosion warehouses, but not farboi.
Another important point: grounding may be a small support, and for which it is important to have good contact. Vіn bezpechuєtsya zvaryuvannyam. All seams are welded, and the quality of the seam may be high, without cracks, cavities and other defects. Once again, best respect: grounding at a private booth cannot be worked on threaded connections. In the course of time, the metal oxidizes, collapses, opir bagatorazovo grows, zahist pogirshuetsya chi vzagali pratsyuє.
It is even more unreasonable to win as grounding pipelines or other metal structures that are in the ground. For an hour, such grounding is practiced at a private booth. After an hour, the pipe sticks through electrochemical corrosion, activated by strums, oxidize and collapse, grounding becomes non-functional, like a pipeline. Therefore, it’s better not to beat the earthlings.
How to spawn correctly
Let's take a spatula out of the form of a grounder. The most popular among the looking equal-sided tricot, at the tops of which are clogged pins. More line roztashuvannya (there are three pieces, only in a line) and at the sight of the contour - the lines are clogged near the booth with a crop of about 1 meter (for booths with an area of over 100 sq. m). Shtiri between themselves with metal smoogs - metal slick.
Order dіy
From the edge of the booth to the place where the pin is installed, it should not be less than 1.5 meters. Digging a trench on a vibranium dilyantsi near an equal-sided tricot with a side of 3 m. The depth of the trench is 70 cm, width - 50-60 cm - so that it was easy to cook. One of the peaks, as a rule, is dug up closer to the booth, and run out of the booth with a trench, where the depth is not less than 50 cm.
At the tops of the trikutnik, pins are hammered in (a round bar or a 3 m zavdovka coil). Above the bottom of the pit, close to 10 cm. The vin is 50-60 cm lower for the rіven of the soil.
To the protruding parts of the shearing / kutochkіv, a metal bond is welded - a smuga of 40 * 4 mm. Grounding works with a budinka should be covered with a metal smug (40 * 4 mm) or with a round conductor (with a diameter of 10-16 mm 2). Smugu zі created by trikutnik іz metal tezh zvaryuyut. If everything is ready, clean the zvaryuvannya from slag, cover it with an anti-corrosion warehouse (not farboi).
After re-checking the grounding support (with a blast, it can be changed to 4 ohms), the trenches are covered with earth. At the ground, it is not to blame for the great stone, but for the wakefulness, the earth is rammed down by balls.
At the entrance to the booth to a metal smuga, a bolt is welded to the ground, to which the copper conductor is fastened in insulation (sound as farbvannya grounding wires - zhovte іz green smog), a peretin lived no less than 4 mm 2.
Weld the grounding of the wall of the booth and weld it on the end with a bolt
In the electrical panel, the grounding is connected to a special bus. Moreover, only on a special maidanchik, polishing to a glare and smearing with grease. Vіd tієї tire "earth" is connected to the skin line, which is bred around the house. Moreover, the development of the “earth” is called a conductor according to the PUE and is unacceptable - it is less than a cable at the warehouse. This means that if your wiring is wired with a two-wire wire, you will have to change it again.
Why can't work earthly earth
Reworking the wiring at the whole booth is extremely time-consuming and expensive, but if you want to operate modern electrical equipment without problems, it’s necessary. Other than grounding the same sockets, it is ineffective and unsafe. I axis why. The presence of two or more such outbuildings is too early to produce before the release of the possession, which is included in the sockets. On the right, in the fact that the opir contours lie down as a soil in a specific skin area. In this situation between two outbuildings, grounding causes a difference in potentials, which can lead to damage to the possession of electric shock.
Modular pin system
All descriptions of earlier additions - from kutochkіv, pipes and shears - are called traditional. Your little one is a great deal of land work and a large area, which is necessary for the power of the earthworker. Everything that is necessary for a small area of contact between the pins and the ground is sufficient for ensuring a normal “roztіkannya” of the struma. Folding may call out the need for zvaryuvannya - otherwise it is not possible to close the grounding elements. Natomist plus tsієї systems - perceptibly small windows. To work traditionally grounding in a private booth with your own hands, it will cost a maximum of $ 100. Why buy all the metal and pay for the brewing, and carry out the repair on your own
For this reason, modular fastener systems appeared. This is a set of pins, which are driven into a depth of up to 40 m. Fragments of pins are connected one by one behind the help of special clamps, which fix them, and they ensure the same electrical connection.
The advantage of modular grounding is that the area is small and less work is required. A small pit is needed with sides 60 * 60 cm and a depth of 70 cm, a trench that connects the ground with a booth. The strokes are long and thin, it is clumsy to hammer them in the watery soil. The axis here and went down to the main minus: the clay is great, and it’s like a stone in the backyard, for example, a stone, it’s possible to start a bud. And wiping the haircuts is the problem. The stench is not brewed, but you can see the chi ni collar - food.
Another minus is the high price. Together with the installation, it will cost you the same grounding of $ 300-500. Self-supporting installation is problematic; A special pneumatic tool is needed, which they learned to replace with a perforator with an impact mode. Another need is to re-arrange the support after a skin clogged shear. But if you don't want to get in touch with earth robots, a modular grounding pin is a bad option.
