Description

The application of the 360MVA/500kV three-phase self coupling OLTC interconnecting 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 360MVA/500kV three-phase self coupling OLTC interconnecting 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 360MVA/500kV three-phase self coupling OLTC interconnecting 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:Transformer cooling method AN stands for what: The cooling mode of the transformer is determined by the cooling medium and the circulation method. Since the oil-immersed transformer is also divided into the internal cooling mode of the tank and the external cooling mode of the tank, the cooling mode of the oil-immersed transformer is represented by four letters. ? The first letter: the cooling medium in contact with the winding. O -------- mineral oil or ignition of more than 300 ℃ of insulating liquid; K -------- Insulation liquid with ignition point greater than 300 ℃; L -------- ignition can not be measured insulation liquid; ? The second letter: the way the internal cooling medium is circulated. N -------- The oil flow flowing through the cooling equipment and the windings is a natural thermal convection cycle; F -------- The oil flow in the cooling equipment is forced to circulate and the oil flow flowing through the windings is the thermal convection cycle; D -------- The oil flow in the cooling equipment is forced to circulate, at least in the main winding oil flow is forced to guide the cycle; ? Third letter: external cooling medium. A -------- air; W -------- water; ? The fourth letter: the way the external cooling medium is circulated. N -------- natural convection; F -------- Forced circulation (fan, pump, etc.). ? Therefore, the transformer cooling method AN represents the air convection cooling method.

Q:What is the difference between AC transformers and DC transformers?: Transformer is made of electromagnetic induction principle can change the voltage of the equipment. Transformer has a core and coil composition. Transformer coil sub-primary and secondary coil. In the primary coil in the AC power. Transformer core to produce alternating The secondary coil senses the same alternating current as the primary frequency, and the number of turns of the transformer coil is equal to the voltage ratio, for example, the primary coil of a transformer is 880. The secondary is 88. At the primary access 220V. It will output 22V AC voltage. Transformer can not only buck can also be boosted. Long-distance transmission are generally used to increase the voltage transformer. Reuse in the power transformer to the voltage we need

Q:I just saw the movie and it has left me with a thirst for more on the story of transformersbut where can I turnComics, animated series?Thanks: It started as an animated series in the 80s. Check out youtube for some clips.

Q:I have been reading wikipedia and have gotten confused.Va.Number of Coils on side a---- ._________________Vb.Number of Coils on side bwikipedia mentioned how power companys use transformers for converting to high voltage power li nes then use transformers to bring the voltage back down.Focusing on the transformer that jacks the voltage upwirea-[side a-Transformerxyz- side b]-wirebso assum wireb is the high voltage power line.--Which side of transformerxyz would have more coils ? My guess is that side b has more coils then side a--Is it safe to say that the wattage of side a is equal to side b?--they said something about magnetic flux, does this just mean that the material connecting side a to side b has to be magnetic?--they said that the insulation wears down in transformers over time due to heat. what is causing this heat?--they said something about leakage and spacing of coils, what does this mean?tyVVVVVVVm: The previous answer is correct, but the following may be helpful. A transformer works by the linking of changing magnetic flux produced by one loop or coil (the primary winding) with another coil (the secondary). That is why transformers only work with alternating current or pulses. Magnetic iron has the ability to increase the magnetic flux produced by a coil. This is called its magnetic permeability and can increase the flux produced by factors of several thousand or more. Leakage flux in a real transformer is the amount of flux produced by the primary that does not link the secondary. This flux is wasted and reduces the efficiency of the transformer. Heating of the wire insulaltion not only comes from the resistive heat of the windings, but also the heat produced in the magnetic material (core) of the transformer. These losses are called eddy current and hysteresis losses and can be quite substantial. The reason that cores of transformers are laminated (stacked thin sheets of magnetic iron) is to reduce the eddy current losses.

Q:How long does it take to restart the transformer?: What are the requirements for the commissioning and outage of the transformer? A: (1) the new operation of the transformer must be rated voltage under the impact test 5 times, overhaul after the impact test 3 times. (2) the transformer put into operation when the first cooler, cooler running for a period (about 15min) time, until the oil temperature is no longer rise and then stop. Disconnect the transformer first. (3) 110kV and above in the neutral point direct grounding system, put into operation and outage transformer, the operation must be grounded before the neutral point, after the operation and then decide whether to decide whether to disconnect. Transformer neutral point access to the arc suppression coil should be first after the exit. The neutral point of the two transformers should not be connected to a neutral bus with an arc suppression coil.

Q:A transformer rises the voltage in proportion of 1 to 10. If the power in the primary coil is 100 watts, we should expect a power of ____ watts in the secondary coil. a) 10b) 100c) 1,000: Transformers can step up voltage, but in doing so, they step 'down' the current. Ideally, the voltage will rise by the same proportion as the current will fall. And since power is PVI, the power will remain unchanged. So the answer is that the power in the secondary should be the same as the power in the primary, which is 100W.

Q:A topic that: a three-phase transformer wiring is YN, Y, a0, d11, all mean what? Three-phase transformer how four ways to connect it?: This is the wrong label. The reason is as follows: 1, regardless of the winding of several transformers, its high voltage (primary side, input) may only be a set of windings. Which transformer has two inputs ah! Because only the representation of high-voltage connection, only with capital letters. 2, so the second letter (Y) is wrong, maybe redundant. Obviously, this is a three-winding transformer, the high voltage is Y connected, and there are zero line leads. The medium pressure and the high pressure are autocouple, so it is a0. A0 of course shows that the medium pressure in the phase with the high pressure phase. Is it mistaken for here that u should be u? The The 3, low pressure, of course, do not have to say is d then. 4, now the new standard of writing is not used (,) number to separate. If this is a standard three-winding transformer (the second winding is auto-coupled). Then it is: "YNa0d11" Convenient words, give an echo. So you take a closer look, whether as I said. Title may be wrong in expression.

Q:hey all , i have 2 phase welding machine fed from 30A 3 phase circuit breaker , at high loads above 40A CB cut off the Supply . the problem is i cant change the CB size bcoz it Contrary to legislation in the country . Can i used scott t transformer to balance the load at the main 3 phase ?: you're starting to be to be meant a single section welding device. This unit includes 2 supply lines. those lines may be linked to any 2 lines of a three-phse ability supply device.only connect one line to L1 and the different line to L2, only examine the line to line voltage of the flexibility supply. It must be the comparable by way of fact the welding device score, say, 380VOLTS, 50 Hz.

Q:Hi, I replaced two 12V 20W halogen bulbs (wired in parallel) by two 3W 12V LEDs also in parallel. The problem is that the transformer (in a kitchen fume hood) seems to shut down when both LEDs are connect. It can take one but the two cause problems. I guess this might be caused by the very low resistances of the the 2 LEDs connected in parallel that short circuit the transformer? How can I reduce this short circuit without causing significant voltage drop for the LEDs? I tried using them in series but they won't work because they will then each have half the required voltage. Of course the idea is o find a solution that will also not significantly interfere with the energy savings associated with the change of halogen by LED. Btw, the LEDs are MR16 and have their own little voltage regulator/stabilizer circuit (or whatever that is).Thanks!: What does 12 volt LED mean? LEDs operate at voltages around 2.8 to 4 volts, not 12 volts. If it means the LEDs have a resistor built in, so they operate from 12 volts, then you should be fine, and the transformer should not shut down, as the current would be a low lower than the halogen lamps drew. So I suspect these are NOT 12 volt LEDs, and they need a series resistor which is missing, so the current is much higher than it should be. Probably means the LEDs are cooked already. Another possibility is that the 12 volts for the halogens is AC, not DC, and the LEDs require DC. So you need to look at the specs on the LEDs, and also check the 12 volt supply. I suspect it is AC. .
