Description

The application of the 380MVA/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 380MVA/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 380MVA/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:Power transformer primary current and secondary current: Once refers to the power side, the second refers to the load side

Q:10KV distribution transformer how to calculate the tap voltage: To 10 ± 5% of the gear, for example, the transformer for the third gear, each level gear can be adjusted 10000 × 5% = 500V, then Ⅰ file tap voltage 10000 +500 = 10500V, Ⅱ file tap voltage 10000V , Ⅲ gear tap voltage 10000-500 = 9500V

Q:My device has 50KW should be used with much transformer: On the use of 50KVA transformer on the line, because your device will not appear at the same time the maximum power.

Q:If a transformer rating 240vac 50hz being supplied by a source 240vac 60hz,will it get hotter than by 240vac 50hz source?: Inductive Reactance increases proportionally with frequency. Therefore, if the supply voltage remains the same but the frequency increases, the impedance increases. This will lead to an increase in heat. If the supply voltage remains the same but the frequency decreases, the impedance decreases, which means that less heat is produced. The answer to your question is NO.

Q:For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?: You are right. The value of a coil is measured in Henries and is determined by number of turns, size of wire, type of wire (commonly copper or aluminum). That is the reason you should not leave adapters and chargers plugged in. When not in use they should always be un plugged from power source.

Q:Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.: Transformers don't normally fail for no reason. In most cases, something caused the transformer to fail, so it is incumbent upon the person servicing the unit to figure that out first before installing another transformer and powering it up. If it can't be determined what caused the failure, it is best to install an in-line fuse so, if there is an issue, the fuse will blow before taking out the transformer and the circuit board. Having said that, in a lot of cases, the circuit board has its own built-in fuse to protect the board from cases such as yours, so the board fuse should have blown before the board became damaged. I don't have much confidence in what your man did, so I'm more likely to blame him for blowing out your circuit board and the new transformer, unless he can prove otherwise.

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?: If the three-phase transformer has four windings can not have four kinds of wiring way?

Q:Are you agree with me that Transformers The Movie (1986-Cartoon) is better than Transformers (2007) in terms of it's storyline, dramatic and character's behaviour?Transformers (2007) is such a great movie but i think i prefer 1986's cartoon. I always make me want to cry.: I'v neva seen the cartoons but the movie is brilliant(Josh Duhamel is sssssooooooooo hhhhooootttt!!!!)

Q:I don't know how this conversation started today, but a couple of my friends asked me who would win in a battle Voltron or the Transformers. They did not specify which version of Voltron or which group of transformers. Give me a scenario and tell me what you think!: Voltron would kick ther azzesTransformers would not kill Voltron . Voltron on the other hand would form blazing sword and hack them into spare partsWinner Voltron. nuff said.

Q:If a transformer is rated for a maximum winding current of 10A, would it be permissible to operate it with 10A of input current when the secondary voltage to the load is 40V? Can you explain to me why?The information on the auto transformer plate wasInput 240V/ 50/60 cy 3HPoutput 0-240/280V 20 ampsThe parallel load resistance is 34.5 ohms: At 40 V and 10 A the VA is 400 on the secondary side. At 240 V on the primary side the current is 400/240 which is 1.66 A. If the load on the secondary side is 34.5 ohms at 40 V then the secondary current is 40/34.5 1.16 A and the the VA on the secondary side is 40 x 1.16 46.4. T he VA on the primary side then is 46.4 and the primary current is then 46.4/240 0.19 A. 3 hp is 746 x 3 Watts 2238 W and its rated current on the primary side is 2238/240 9.325 A. In other words the VA loaded on to the secondary side is the same VA (more or less) as that on the primary side.
