I did not feel any “electric shock”, but a burnt area of skin remained on the surface of the finger. Own consumption of the HV generator The only disadvantage of this method is a very caustic smoke. Even when turned on normally, it does not immediately light up at full power, but the brightness increases gradually as the gas inside warms up. The price is very pleasant. Well, the “finger test” Increasing the output voltage The first video is unpacking and assembly. I fixed the high-voltage generator board itself next to it, soldered the ends of the high-voltage winding to copper wires, fastened with screws and curved into the shape of a “horn arrester” . Next, I lowered the transformer into molten paraffin for a few minutes so that it (paraffin) soaked the windings, then dried the transformer on a napkin I also have a rare beast among energy-saving lamps – an induction lamp: Video version: I can recommend this kit for assembly with the younger generation. Assembly Next, you need to solder the resistor and the diode according to the markings on the board. In principle, 5 mm is not the maximum breakdown distance for this generator, however, by increasing this distance, there is a chance to get a med-turn breakdown of the high-voltage winding, which happened to me, therefore I had to order another set and pre-impregnate the transformer with paraffin. I will also show you how to use this kit to make an ordinary household light bulb (both energy-saving and LED) glow, from just 1 battery cell. Other experiments
Kit for assembling a high-voltage generator. 15,000 volts from a single battery or how to light a 220 volt lamp from a battery.
Feels like touching something hot. – 120 ohm resistor; As the voltage increases, the discharge becomes brighter and denser, more than 4.1 volts (1.98A) I did not raise the voltage, being afraid to burn the generator. Hello friends. — a plastic tie for attaching the transformer to the board; – radiator for the transistor; https://jiji.ng/ajah/trucks-commercial-agricultiral/isuzu There is no impregnation. To understand at what voltages the generator operates and what currents it consumes, I powered the generator from an adjustable PSU: This can be done with a sharp knife or sandpaper. The lamp lights up regardless. The high-voltage winding consists of 6 sections connected in series. Summary: There is no diagram in the kit, it is assumed that the assembly is carried out according to the marking of the printed circuit board: Solder into the board in accordance with the marking, where there are thick strips – a winding with a thick wire (collector), where the strips are thin – a winding with thin wires (base). — 6 pin comb. The LED lamp does not burn weaker. Today I want to talk about a kit for self-assembly of the simplest high-voltage generator as much as 15,000 volts (as the manufacturer claims). The experiments turn out to be quite amusing, although, probably, unsafe. In principle, you can proceed to a trial run, for which we connect a regular Li-Ion 18650 battery to the wires and try to set fire to the paper with a high-voltage discharge. The review was written for a very long time, more than 2 months. in the middle of the test, the high-voltage winding of the transformer burned out, or rather failed, (turn-to-turn short circuit), so I had to order another set and take additional measures to prevent such excesses The main highlight of this generator is its low supply voltage: only 3.7 volts, i.e. it can run on a single lithium cell. In connection with the currently unclear situation with the fate of Youtube on the territory of the Russian Federation, I will also give links to these videos on Zen. Let’s try to play around with the "ignition" of various lamps, let’s start with luminescent energy savings The lamp is quite specific, it has no contacts at all inside the glass bulb and the plasma glows in it, resulting from the ionization of gas by a high-frequency magnetic field. – an unnamed n-p-n transistor in the TO-126 package (on the product page, this transistor is called N20); This lamp also glows, but very weakly. The ends of the high-voltage winding must be soldered to a set of contact combs (through one), i.e. the spark gap will be about 5 mm. This voltage can be most clearly measured by measuring the length of the breakdown gap. The discharge appears at a supply voltage of 2.8 volts (1.77 BUT). Therefore, this procedure must be done in a well-ventilated area. The queue for the LED lamp: Paschen’s Law can tell you more deeply about this The set contains: It is necessary to connect low-voltage windings in series, i.e. the end of one with the beginning of another. To do this, I took a candle in a glass beaker and melted it in a water bath However, for understanding, I drew a diagram: This is a standard blocking generator, which is a signal generator with
transformer feedback. The base winding of the transformer is wound with a thinner wire than the collector one, the turns were not counted. The next step is to solder the wires and the switch: – diode UF4007; And by soldering the wires to the contacts “through 1”, as in this case, we get 5 mm, which is approximately 15 kV, because the average breakdown strength of the air is about 30 kV/cm. – M3 screw for mounting the transistor on the radiator; The distance between adjacent comb contacts is 2.5 mm. On the product page
it is indicated that this high-voltage generator generates a voltage of 15 kV. It remains to solder the transformer, for which it is necessary to tin the ends of the low-voltage windings. First you need to screw the transistor to the heatsink, and then solder it (transistor) on the printed circuit board. The second one is modernization and experiments. Therefore, experiment with — printed circuit board; Fluorescent lamps burn confidently and quite brightly. Composition of the set This must be done to prevent interturn breakdown of the high-voltage winding. Moreover, it is enough to connect the lamp with just 1 contact to any high-voltage conductor. To do this, they must be cleaned of lacquer insulation. After making sure that the high-voltage generator is working, it remains to fix the transformer on the printed circuit board with a plastic tie The next step, I took a wooden block and twisted 2 screws at a distance of about 3 cm from each other. I experimented with the shape of this spark gap for a long time, it is interesting to observe the discharge, it appears at the narrowest point, then moves up and goes out at a distance of about 1 cm, i.e. indirectly, we can say that the generator is capable of developing a voltage of about 30 kV (this process can be seen more clearly in the video version of the review below). I traditionally use an aspirin tablet as a flux for this. – high-voltage transformer; — key switch; As a result, the generator consumes up to 8 watts.
