Grounding is an electrical element that ensures the safety of the operation of electrical devices: machine tools, electrical machines, computers. It removes static electricity, and in some cases atmospheric electricity, which is very important during a thunderstorm. They also protect from electrical interference that can cause a malfunction in the operation of radio receivers and computers.
Necessary
- - the wire;
- - lead sheet;
- - clamp;
- - welding machine;
- - soldering iron;
- - file;
- - sandpaper;
- - a shovel.
Instructions
Step 1
You can use central heating pipes for grounding. To do this, clean the pipe section from paint, rust and dirt. Place a lead sheet gasket over the cleaned area and clamp it to the pipe with a metal clamp. Solder the ground wire directly to the clamp bracket. If you are grounding a computer case, use one of the screws to secure the option cards. Screw the second end of the wire to it, having previously stripped it.
Step 2
You can also make a special ground. Take a metal pipe or rod up to 5 cm in diameter and 3 m in length. Remove paint, oil, rust and other contaminants from the surface. Drive the pipe into the ground so that its upper end is 0.5-1 m below ground level. Weld a steel wire with a diameter of about 5 mm to the pipe. This will be the grounding tap. Cover the welding area and the section of the wire leading to the surface of the ground with bitumen, tar or asphalt varnish to insulate against corrosion. After that, cover the top of the rod or pipe with soil. This grounding method is also used for lightning rods.
Step 3
If you are in a rural area and you have nothing but a piece of wire at hand, do otherwise. Tie a weight to the end of the bare wire. Any metal object can be used in this capacity. An old bucket, for example, will do. Throw this item into the nearest body of water. Connect the other end of the wire to the grounding terminals of the device (for example, a radio receiver). Note that grounding is best done to ensure contact with groundwater. In winter, it should not freeze through, since ice does not conduct electric current. Therefore, when organizing grounding, it is necessary to deepen it below the level of soil freezing.
Step 4
If the soil is sandy, then arrange the grounding as a closed loop made of iron strips in the form of a rectangle or square with sides of 3-5 m. salt. But this method is best avoided as it is harmful to the environment and leads to rapid destruction of the metal parts of the ground.
