Q:Anybody with information on Ferrite Core Transformer Inverter Circuits For Hobbyist?
Google joule thief, for some really simple circuits that produce several volts 90k hertz ac for powering one LED from one almost dead cell at less than one volt. Yes, ferrite core, sometimes only one winding, but a second winding can be the output voltage. Possibly the circuits can be scaled up for more power out and a somewhat lower frequency.
Q:Does a transformer act as an inductor at the same time while in use?
The primary of a transformer has a fairly large inductance called the magnetizing inductance. This inductance could be used as a filter, but it is not a good idea. First of all, it will not support any appreciable DC current, because it will saturate. In addition it is usually very nonlinear. If you want to filter the input voltage use a separate filter.
Q:What is the rated current of the 80KVA transformer?
Rated current formula: I = P / 1.732 × U = 80000 / 1.732 × 380 ≈ 122 (A) (Current contains active and reactive current)
Q:Transformer oil filter method
So only on-line oil treatment. Oil filters require an external oil filter and oil tank. The new oil (has been qualified, insulation pressure are qualified oil into a clean oil tank inside, the external oil filter and oil drums and transformer tubing as a whole, the external circulation of online filter oil). Mainly: 1, online filter to continuous operation, to ensure that the weather is fine air humidity less case, under the conditions of the best conditions for 214 hours of continuous operation.
Q:50KVA transformer maximum load is how much?
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). The circuit symbol is commonly used as the beginning of the number.
Q:250KVA transformer maximum load how much KW power?
Transformer economic operating coefficient is 0.75. Transformer output capacity and power factor, the power factor is 1 when the transformer output current is the largest, generally require more than 0.9. When the power factor is 1, the transformer output current I = 250KVA / (1.732 * 0.4KV * 1) = 361A. The observed current is the most intuitive. Three-phase active power P = 1.732 * U * I.
Q:What is a transformer?
Impedance matching: the most common is the electronic circuit, the output and input connection, in order to signal unobstructed, usually using the transformer impedance matching, such as the old-fashioned broadcast, because it is using constant pressure output, speakers are high impedance horn , So it can only match with the output transformer. So, daily life can not be separated from the transformer, industrial production is also inseparable from the transformer.
Q:Is the transformer a power supply?
Here, are relatively speaking. 1, if your equipment behind the transformer, then the output of the transformer is your power. 2, if your equipment in front of the transformer (such as a substation or generator), then the transformer is your load. 3, for example: at home, the adapter (to the phone with a transformer device), it is for your phone, that is, power, you said the socket, it is the load. 4, but if it is necessary to define it as what equipment, then it does not belong to the power supply equipment (power supply with a large generator, a small dry battery). It is able to change the power supply mode of the device.
Q:can ferro alloy smelting furnace transformer can be converted to higher voltage to handle ferronickel smelting?
You need to provide more information about the original use of the transformer. Nickel smelting is a very specialized application that calls for a 'submerged arc'. Basically, the arc is fairly short and will essentially be submerged in a layer of slag on top of the molten material. It is a semi-continuous process in that periodically, some of molten nickel is poured off. The stream of molten nickel is blasted with water that causes the nickel to solidify into small pellets. Steel melting furnaces, by contrast, involve a much longer arc. The slag layer in the furnace is much thinner, and much of the arc is above the slag. It is a batch process in that once the 'campaign' has been completed, the entire melt is 'tapped' - poured into a tundish either to be cast into ingots or to feed a continuous casting process to make billets, slabs or even plates. There are other smelting processes for other materials - for example, silicon is produced via a smelting process. I would guess that if the voltage requirements of the nickel smelting process are different from the requirements of the original utilization, then it would be necessary that the transformer be redesigned and rewound - something that I would not expect to be very practical.
Q:gas furnace transformer?
should be on the furnace. however the pilot light doesn't need the voltage to light. the solenoid does need the voltage to open.
