How to change transformer into platinum machine

How to change transformer into platinum machine;

A, 150W bulb, the brightness is about 4 minutes. The greater the load, the lower the vibration frequency of the contact. The contact spark is relatively small, only a small bright spot, and the contact is not hot at all. It should be said that the efficiency is really high and it is definitely worth a try. Thank you very much for your strong support and generosity! I made it 10 years ago. At that time, a transformer of about 10W was used, and I forgot the specific data. The secondary voltage is only about 50v when v4 is wound by m every turn, but it is not turned on, so the contact attraction is very small. I learned a trick from the author today, and the effect is acceptable. The effective range of each electrode is about 0.8 meters, which is particularly energy-saving. Upstairs, I asked the next opening. I think it is possible to connect a relay with a large contact in series on the primary side, remove the coil, wind it around the far winding several times, and then connect it in parallel with the primary side, but it may affect the reverse high voltage pulse. 500W, UPS transformer, combining two groups of primary with the same name, with higher output power. I made one, but it's not easy to shake. The capacitor 8UF6UF is connected in parallel with 450V. 58 times before the line 700 (the line is not enough). It has a red light of 100W, and the voltage is about 100V. The voltage in the output discharge bucket is only over 50V, which can electrocute frogs. I don't know how to improve it My EI platinum machine is characterized by small sparks. The depth is about 1 m and the width is about1.5 m. The fish in the middle of the poles are basically white, but they don't float. Fish outside the poles have a greater chance of escape. Because the UPS transformer is directly used, the spark-extinguishing capacitor used is 450V660UF, and the light with 200W is bigger than that in water, and the spark in water is very small. Besides, the water quality in our place is very clear, so ... I'm just a hobby, and my fishing skills are poor. When I was free, I saw that everyone was playing with a platinum machine, so I spent more than 80 yuan to buy some materials and make a platinum machine to play with. 550ML medium copper wire is about 1KG, 25 yuan medium copper wire is about 0.3KG 0.69, and six green papers are about 5/1m. Plus casing or something, it looks like 89 yuan! Platinum costs 40 yuan, I don't want it. I found some high-power switches to fold a pair and used them. The capacitor has a special audio capacitor of 20uF/250V, and the original Panasonic capacitor of 4.7uF/250V is shown in the picture. Need 18 yuan, 1. I took some from the factory when I was designing the digital amplifier, hehe. There is no temperature at all when working, and other capacitors will be a little hot! The no-load current is too small, generally only 0.69A, but actually only 0.5A, which means the output power is small. The load of 25W bulb is only over 400 volts, and the bulb of 100W turns yellow, and the peak value seems to be over 200 volts. I recently browsed the power supply network for a period of time and made my first platinum machine. The iron core is 3 * 3 * 65438+. Primary 1.5*2 is about 85 turns around two layers, and secondary 0.67 is about six turns around 1050. The capacitance is 25UF, and the amount of platinum is changed through the contactor contact. No-load output voltage is 350V, 40W bulb is only 150V, and the spark of platinum can't be reduced as the masters said, which is always a little cheap! The EI75 transformer core for 300W platinum machine has a part of I removed from the platinum point surface. The primary wire of 1.2 is wound with two strands 14 turns, and the secondary wire of 0.69 is wound with 500 turns. The capacitor of 10UF consists of platinum resistor and transistor. Therefore, the transformer uses a lot of copper, and its iron core has a large volume. Because its iron core does not form a closed loop, the leakage inductance of the platinum machine is very large, so the power consumption is very low. Just 20-40%, not more than 50%. Its copper consumption is the largest, the primary wire is thick, 40- 120 turns, and the secondary wire is 25-35 times that of the primary wire.

This experiment is meaningless. I once made a 150W platinum machine, and the power of the 40AH battery was used up in two hours, while the transistor with the same power was put into the water 15 hours. The efficiency of transistor machine is relatively high, generally 50%-75%. The biggest advantage of transistor machine is its stable performance. Generally, several tubes are burned during the trial operation, and they will not come out for several years. When the power supply is reversed, the diode is not conductive, and the relay is not attracted, the whole machine will not work, and the switch used in hand can also control the on-off of the relay coil with a microswitch, thus controlling the work of the whole machine. This is the best of both worlds. For such a large power, there is no other best way except connecting the diode to the relay coil. If the low-voltage drop high-power diode is connected to the power supply circuit, the cost is not a problem (there are many in some abandoned computer switching power supplies), but it only consumes a few watts of power. The distance between the poles of the electric fish is about1-3m, and the output intensity of the machine can be adjusted within 2m (depending on the water quality and weather). Generally, shallow water is turned down (saving electricity) and deep water is turned up. For example, if the fish sinks to the bottom and the adjustment is too strong, the value should be appropriately reduced. When the adjustment is too large, the machine will automatically protect itself from working. At this time, it should be reduced, and the appropriate value can be selected according to the actual water level to achieve the best effect. Electrode manufacturing: the fishing ring is about 16 cm in diameter and made of iron wire or stainless steel with a diameter of 6-8 (mm); The other electrode is made of the same material, and its length is about 20 cm. Two high-voltage lines must be welded to two electrodes, otherwise the contact will be poor due to corrosion, which will affect the effect. Then, the two electrodes were fixed on two bamboo poles of 1.5-2 m respectively. The fishing rod of the fishing net is connected to the high-voltage anode, and the other rod is connected to the high-voltage cathode. Fishing nets, fishing rods, one on the surface and the other under the water, can be underwater or far away. Press and hold the switch (5- 10 second), slowly move the two electrodes on the water surface until the fish floats, then release the switch and start fishing. Electric fish are separated by 2-3 meters at a time. When working, the distance between the two electrodes is1-3m. Precautions: 1, do not touch the high-voltage end, pay attention to safety, and wear sweatpants when working. Ensure that platinum will not only corrode to one side! The machine can use 12V 16V24V battery. 3. When the machine discharges, it will make a sound, if platinum often sticks together! It means that the battery is dead and should be stopped. 4. Emergency lighting can choose 100W bulb, and the frequency is adjusted to the middle position. Please replace it with a new platinum after corrosion.

Uses: Accessories: output 12V battery (storage battery), bamboo fishing net lead 1. Making power grid: make two metal rings (preferably steel pipes and copper bars) with a diameter of about 300 mm and put them on the fishing net as fishing net electrodes, and connect the two fishing net electrodes with insulated wires respectively. Then fix them on two 1.5m bamboo poles respectively. 2. Connect the positive and negative poles of 12V battery to the battery clip of the machine, and then connect the other ends of the two insulated wires of the power grid to the output terminals of the machine respectively. 3. The high and low voltage switches on the machine are determined according to the depth of water. High voltage is used in deep water and low voltage is used in shallow water, which saves electricity. The frequency adjustment on the machine is for fishing. 5. Take a bamboo pole and put two electrodes into the water. The distance between the two poles is one to two meters (depending on the power of the machine). Keep pressing the switch, corona fish. Turn off the switch and catch fish! Note: 1, the machine itself should not get wet. It is best to use a boat for fishing. When the machine is working, people should not touch the power grid or the electrodes! 2. Each discharge is limited to 5 seconds. Do not turn on the machine when using, so as not to damage the high voltage rectifier and capacitor. The high-voltage electrode cannot be short-circuited, and the positive and negative electrodes cannot be reversed. 3. If the relay jumps slowly or doesn't pull in during use, it means that the power has been exhausted and can't be used any more. 4. The machine will generate a certain amount of heat when it works. Users should not remove the covers at both ends of the machine. So as not to damage the machine. Platinum machine can't design voltage like ordinary transformer. The voltage ratio is not necessarily equal to the turns ratio. I'll give you a parameter. Primary 90- 120 turns, secondary 800- 1500 turns. Remember not to have too many secondary issues.
