How to make a Tesla coil and what does a Tesla coil do?

3 iron ingots, 5 energy coils, 1 screwdriver.

High voltage transformer ---=1000win220 vout>=10kv a. (It is difficult to buy, and it generally needs to be customized, and some second-hand electronic equipment cities in the south have had in110vout6300v600w transformers.) I just don't know if I can still buy it.

2.A large number of electrodeless capacitors: If the CBB capacitor needs to be prepared about 100 pcs.

Available at electronics stores (capacitors are very important!) It can be said that it is the heart of the entire Tesla coil, so the high quality of the capacitor will make your last Tesla coil even more dazzling! Quality mainly refers to:

Good high-frequency performance.

Low self-attrition. Low inductance [important].

Long lifespan. Good insulation performance.

3.PVC pipes with a diameter of 13 cm and a length of 1 meter (wall thickness cm), PVC pipes will also be used, and insulating panels with a thickness of cm (not wood!). Preferably plastic) about square meters, centimeters thick insulating board (not wood!)

About a square meter, these can be bought in the Home Decoration City (the kind of big market where you buy paints, plates, tools, etc.).

4.Wire, multi-core copper wire, 1000V50A about 6 meters electronic accessories store available (10kV1A wire 3 meters).

5.The inner diameter of the pressure-resistant enameled wire is meters long, and the electronic accessories store is bought.

6.Copper pipes with a diameter of 1 cm (wall thickness of 1 mm or more) are 8 meters long, and copper pipes with a diameter of 3 cm thick and 1 mm long and 1 meter long can be purchased in places such as auto parts or hardware.

7.Electric hand drills, screwdrivers, hand saws, pliers and other tools, ordinary screws, plastic screws, epoxy glue, steel rulers, etc.

8.The exhaust pipe (made of metal, bendable, with a diameter of more than 10 cm) for gas water heaters is calculated at the end of production.

9.Some other common things, let's look for them as you go.

The Tesla coil is a distributed parametric high-frequency resonant transformer that can obtain millions of volts of high-frequency voltage. The principle of a Tesla coil is a device that uses a transformer to boost the voltage of a normal voltage, and then discharges it from a discharge terminal through a two-pole coil. In layman's terms, it is an artificial lightning generator that can also be used for long-distance power transmission.

Tesla coils were difficult to define, and Nikola Tesla experimented with a large number of various coil configurations. Tesla utilized these coils for innovative experiments such as electrical lighting, fluorescence spectroscopy, X-rays, high-frequency alternating current phenomena, electrotherapy, and wireless power for power transmission.

Step 1: Turn off the secondary device first, then the primary device!

Primary winding at the bottom (green wire).

Secondary winding (gold wire).

Put one end of the wire around the top of the pipe in a small slot. Slowly, and carefully, begin to wrap the coils, making sure that there are no overlapping wires or spaces. This step is the most tedious part, but spending a lot of time will produce very good coils.

Every 20 revolutions or so, if the coil begins to unravel, place a circle of masking tape around the **ring as a barrier. When finished, wrap a tight strip of tape around the top and bottom of the ** circle and spray it with 2 or 3 coats of enamel. Boy model.

Step 2: Connect the wireless power transfer system wireless power transfer (Tesla coil) circuit.

The connection of the primary and secondary is shown in the circuit diagram, switching the battery through transistors and resistors and switching. The smaller windings in the diagram are the primary windings, and the longer windings are the secondary windings. You can also add aluminum balls to the top of the pipe and connect the auxiliary switch end to the pipe, which will act as an antenna.

Be careful not to touch the auxiliary power supply when the power supply is turned on.

Step 3: Start the Tesla Coil.

Take your Tesla coil outside for the first run, as it's really not safe to run anything that might be powerful indoors. Be careful, there is a risk of fire. Flip the switch and place a tube light or CFL bulb in close proximity to the wireless power transfer device and enjoy the light show!

The Tesla coil making tutorial is as follows:

1. Materials. 1. Enameled wire: the diameter can be, about half a catty, depending on the size of the secondary coil, the electronic market can buy **20-30 yuan.

2. PVC pipe: a 50-75mm, length 30-50cm, a diameter of 100mm, a length of 10-20cm, a total price of 10 yuan aluminum exhaust pipe, as the top end of the discharge, a length of one meter, a diameter of about 80mm, **15 yuan or so The above two materials can be bought in hardware stores or building materials market.

3. Induction cooker capacitor: 10-30 pcs, about one.

4. High-voltage power supply: You can use NE555, TL494 and other chips to drive the TV high-voltage package to produce more than 20000V high voltage, but the better way is to use a ZVS driver, which has high power, less heat, and stable and reliable work.

Second, the production process.

1. Wound the secondary coil and use enameled wire to wind 1000-1500 times on the PVC pipe with a diameter of 50-75mm.

2. Make the discharge top, made of aluminum exhaust pipe, in order to facilitate fixing, you can clamp the aluminum tube with two stainless steel bowls one by one, and fix the hole in the middle with screws. It should be noted that the tip of the discharge should be connected to the enameled wire at the upper end of the secondary coil.

3. Connect the enameled wire on the top of the discharge and the secondary coil with a wire.

4. Make a primary coil, wrap the thick wire around the PVC pipe with a diameter of 10cm, in order to facilitate debugging, you can also fix the single-core copper wire on the pipe after peeling, and pay attention to leave a gap for each turn of quality inspection.

5. Make a primary capacitor array, every 10 capacitors are connected in series as a group, and multiple groups are connected in parallel according to the need, and each capacitor should be connected in parallel with a 1m resistor for safety reasons.

6. Make a lighter, fix two metal objects on the insulator, the spacing is 3-5mm, in order to dissipate heat, you can use several more groups in series.

3. Adjust the resonance.

The key to making a Tesla coil is resonance, that is, the primary LC frequency should be equal to the secondary LC frequency.

The number of turns of the primary coil should not be too small, when the number of turns can not meet the resonance conditions, you can adjust the primary coil by increasing or decreasing the capacitance group, and then adjust the primary coil, after determining the approximate number of turns, connect the circuit well, and observe the discharge effect with electricity.

Then the power is cut off, and the number of turns (e.g. turns) of the primary is fine-tuned until the arc is longest.

4. Precautions.

Tesla coils belong to high-voltage equipment, and it is strictly forbidden to touch any part of the circuit when it is powered on!

After these steps, a simple Tesla coil is made.
