 Description

 

The application of 300MVA/ 230kV export America phase-shifting transformer can significantly improve the economy of the UHV substation, and matches well with the transmission capacity of UHV 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 application of 300MVA/ 230kV phase-shifting transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV 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 UHV 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 UHV transformer 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 UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of  300MVA/ 230kV phase-shifting transformer, 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 UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q:What if I put a rectifier before the transformer?
You are asking some strange questions. You do not have a very good understanding of transformers. A transformer ONLY works with AC. This is why Tesla argued for AC being supplied to houses. With a simple transformer, the voltage could be increased for less loss on transmission lines and then with a step down transformer, the AC could be brought into homes. Edison, on the other hand, loved DC and wanted all houses to be supplied with DC. Edison, in an attempt to prove Tesla wrong, invented the electric chair to show how dangerous the larger voltages would be. Edison even electrocuted animals in his electric chair to demonstrate the effects of higher voltages. Fortunately, Tesla won the argument, or we would not be able to transmit electricity over high power lines from generators to homes. Now, a rectifier in the strict sense, does not change AC to DC (with ripple) but simply reflects the negative wave to make it positive. Thus adding a DC component and doubling the frequency. The DC component will simply pass through the transformer (no heating) and the higher frequency will work just great with the transformer. In fact, you can make smaller transformers by using higher frequencies. This was a technique that Sony used many years ago to make great amplifiers and Fisher and Paykel use to make better appliances. (Other companies might also, but I am not aware of them.) So, your transformer will only see an input of 60 V AC and step that down to 12 V. Thus, you will not have the 24 v you need. Why don't you get a better bridge??
Q:TransFormers Or Spider-Man 3 the best summer movie?
Neither. Pirates 3 was way better than Spider man 3, and I haven't seen Transformers so I can't pick it.
Q:How to use the experimental method to determine the transformer iron consumption and copper consumption
No-load test for iron loss; short-circuit test copper loss. I suggest you read the book, see the information.
Q:TN-S system in the transformer side pe line and n-line neutral point how to take
1, this part you can not look at the design rules, the design process is just that principle, should go to check the installation Atlas; 2, the transformer is the neutral point leads to two lines, one to the transformer shell, and then the shell is also grounded; another to the indoor low-voltage cabinet; this is a line after the PEN line, conditions can lead two , But mostly cited a, is shared by PE and N; 3, in the low-voltage cabinet, from the transformer zero leads to the line is divided into two, one neutral line N, the other is to protect the ground PE; generally in order to ground and reliable, where the PE to access the cabinet, The distribution cabinet is installed on the ground network, is directly connected with the ground network, so it is equal to repeat the ground; 4, N line is the work line, for single-phase load, that is, to over-current, or single-phase equipment can not work; and PE line is the protection line, there is no current flow, a current, , And this should pay attention.
Q:Transformers 3 discussion (SPOILERS)?
Michael Bay already said he wasn't going to make a 4th one (I think) Anyway, I was definitely pissed when Ironhide died. I've been writing fanfiction on Fanfiction.net for years, and you get connected so easily with the characters, and right now, Transformers is my main thing to write about. I thought the movie was awesome. Truly epic. It was so sad when Wheeljack (Known as Que in the movie) died. He was so innocent. Just your typical engineer/scientist who was doing his job and how he died was really heart wrenching. I did cry when Ironhide died. Like I said, you get so connected to the characters when you spend years writing about them. I hope Bay changes his mind and makes more Transformers movies. I'd definitely watch them!
Q:800KVA transformer itself is the loss of how much?
S9 type oil change 800kVA no load loss 1400 watts load loss 7500 watts S11 type oil change 800kVA no load loss 980 watts load loss 7500 watts
Q:Parallel AC transformers?
you can connect as many in parallel as you want, if they are all rated at 120 volts AC input. After all, all of the appliances, lights, etc in your house are all connected in parallel, and many of these have transformers. That is what parallel connection is. They all get the same voltage, and they are all independent of each other. .
Q:alternating current transformer ?
Okay. You take a magnet and run it past a coil and you get electricity. You can also simply switch the direction of current (or pulse it) in order to create induction current in a coil. So. if you make a basic AC electromagnet with say. 100 loops of thick copper wiring, and put it next to another coil with say. 10,000 thinner wraps. The coil that gets the juice, will induce a current in the coil next to it. Conveniently, more wraps higher voltage lower amperage, and fewer wraps higher amperage lower voltage. So in the above scenario, under ideal circumstances, we would take a primary voltage off 100 volts 100 amps and turn it in to a stepped-up voltage of 10,000 volts at one amp. The reason this is important is that high voltage travels well over great distances. It is much easier to push the same juice much farther away from its source with very high VOLTAGE and low amps than it is to do it the other way. Amps cause heat, heat causes loss and damage to the carrier wire. Voltage just rides along on the surface of the wire with very little loss. So we step up for transport and back down for use when we are close enough to end-use that the losses are negligible.
Q:Transformers Figures?
you need to look for the collectable series not toys find the G1 collection masterpiece series stay away from anything resembling the new animated series they suck rocks
Q:What is the use of the lower part of the transformer made of rail?
Transformer The lower part of the box has two structures: 1 set the wheels. This requires the installation of the track on the basis of the transformer, and then the wheels fixed on the I-beam track, this way to facilitate the maintenance and installation of the transformer handling, but because of the large and larger transformers, the use of wheels is already less; I-beam or channel as a load-bearing beam. This transformer does not need to set the track, on the basis of the transformer relative to the location of the beam weighing embedded flat steel, the transformer in place after the load-bearing beam fixed fixed on the base embedded parts. Need to move the transformer, the chisel spot welding, with the hoist and other machinery will slowly drag the transformer.
