 Description

 

The application of the 370MVA/525kV single phase double winding generator transformer Power Plant.can significantly improve the economy of the OLTC substation, and matches well with the transmission capacity of OLTC lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for the 370MVA/525kV single phase double winding generator transformer Power Plant. In order to make the products applicable to any OLTC substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity OLTC Transformer” as a key scientific research projects, and entrusted BTW to carry out the research.

During the process of research and development, BTW adopted the advanced design technology and modular design, the transformer can be transported disassembly and with advantages of compact core and winding body, less transportation weight and low transportation cost, effectively solves the need of OLTC construction in the transportation restricted areas. By using the most advanced 3D magnetic field calculation software, BTW performed detailed analysis and calculation for the magnetic flux leakage and eddy current loss of the transformer coil, iron core and oil tank steel structures. Besides, by using of the advanced electric field calculation software, BTW performed detailed analysis and calculation of main longitudinal insulation, and mastered the arrangement of the main longitudinal insulation of large capacity OLTCtransformer and the control of distribution of winding magnetic flux leakage. All of which make the products with low loss, low noise, small volume, strong anti short circuit ability, no local overheating and other significant advantages, and guarantee the long-term safe and stable operation.

The world's first on-site assembled large capacity OLTC Transformer’s right at the first time once again filled the gap in the field of OLTC transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 370MVA/525kV single phase double winding generator transformer Power Plant, which marks BTW has fully occupied the world transformer industry technical peak. The successful development of the product filled the gaps in the domestic technology and met the urgent need of OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:What is the name of the movie they show in the previews before transformers starts?
Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^
Q:What is a true magnetic transformers?
All transformers are magnetic. Perhaps if you would provide a link to the product in question, maybe even to its user's manual, some more information could be gleaned that would allow a more helpful answer. I have no idea what an alien bees unit is. -------- Ok with that I was able to google some more info. So you have a unit that came with a 120V power cord, intended to be plugged into a north american AC power outlet (120V, 60 Hz), and you need it to run on your local current, which is 220. You don't have a power brick or wall wart, the AC goes right to the flash unit. Yes? And the specs say it draws up to 6 amps at 120 volts, 60 Hz. What they're talking about is that you need a true voltage conversion transformer (usually this is actually an autotransformer), NOT any other sort of voltage converter. Travel stores in this country (US) sell these small and cheap voltage converters, made to allow use of certain high wattage devices (up to 1500 watts) on 240 even though they're made to run on 120. But they don't use a transformer, they use a capacitor and a diode. They're ok for things like curling irons and space heaters. They're completely unsuitable for anything electronic. You can usually tell the difference between a true transformer voltage converter and the voltage converter by weight. The latter weigh just about nothing. Whereas even a 50 watt transformer will sit fairly heavily in your hand. For a device that pulls 6 amps at 120 volts, you need a transformer of at least 1000 watts capacity. I've linked one below. Of course that is a US seller, but this will give you an idea of what to look for. Note that it weighs 17 pounds (about 8 kg) and is about 5 x 7 x 8 inches (13 x 18 x 20 cm). There just isn't any way these get much smaller or lighter. .
Q:variable transformer?
variable transformers reduce amps and volts simultaneously Transformers, variable or otherwise, reduce or increase voltage. The current is determined by the load. So if the load is linear, when you reduce voltage, you will reduce current. transformers reduce amps to increase volts True in one sense, but don't take statements like this to be always true under all conditions. You can use a transformer where you need more current at lower voltage, true. BUT, with a fixed load, if you reduce voltage, you reduce current. Of course, this means the input current is reduced even more. Your last paragraph is totally meaningless, sorry. You apparently have no idea of what voltage and current mean. edit: ALL I WANT IS TO CONTROL CURRENT INDEPENDENT OF VOLTAGE With a given voltage, the current is determined by the load. If the load is fixed, then you cannot vary it except by varying the voltage. PROBLEM IS THE ELECTROMAGNET IS SUCKING TOO MUCH POWER AND OVERHEATING Then you need to increase the number of turns, which will reduce the current. You may need to reduce the wire size also to get the number of turns you need.
Q:Transformer 1KVA can load how much security, how to calculate the formula
This is based on the voltage count, such as three-phase 380V. 1KVA current is basically 1.5A
Q:Step Down Voltage Transformer / Regulator?
Install a 125 volt 30 amp receptacle where the oven outlet is and rewire for a neutral in the breaker panel.
Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
Q:How come step-up transformers reduce current in transmission lines?
I can't make too much sense out of your question. Your use of Ohm's law implies a constant resistance, which is not true. Power is constant between the input of a transformer and the output. When you increase the voltage you decrease the current, and the power remains constant (with a small lose due to inefficiencies). .
Q:Microwave transformer wires?
The bottom coil with the 2 tabs is the primary. The 2 red wires leading off to the right is a low voltage secondary with high voltage insulation so that they remain isolated from the other windings. It powers the filament of the microwave tube. The other red wire leading off to the left is one end of the high voltage secondary. It normally connects to a high voltage rectifier and capacitor and then to the cathode of the tube via one of the filament connections. You can expect to see negative pulses in the 2000-3000 volt range at that connection with an available current that is several times the lethal level. The other end of the high voltage secondary is grounded to the frame of the transformer at the rivet at the top center. The anode (plate) of the tube is also grounded through its mounting hardware. Most microwave transformers run hot even when lightly loaded since they are run fairly close to saturation on the B-H magnetization curve. You'll need a fan if you are using it for extended periods. If you carefully remove both secondaries and the steel magnetic shunts wedged in between the primary and secondary windings, you'll have the foundation for winding your own transformer good for about 400-600 watts. First add about 10 more turns to the primary which will cut the core losses significantly by running it lower on the curve. Expect to see about 1 volt per turn on any new secondaries you wind. Don
Q:Where can i find this transformer?
This is an unusual requirement. You may need 2 or more transformers. Do you really need the 2 voltages, or could you develop some of the lower voltage by using DC voltage regulators (if the lower voltages are used for DC)?
Q:Transformer ratio NP:NS?
same consequences as Electronyet in a various way. 7000 familiar turns divided via 350 secondary turns, 20:a million ratio sixty 3 volts on secondary situations ratio of 20 1260 volts on familiar. sixty 3 volts divided via a hundred ohms 0.sixty 3 amps on secondary. 0.sixty 3 amps on secondary divided via ratio of 20 .0315 amps on familiar.
