The application of 32MVA/220kV main 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 32MVA/220kV main 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 32MVA/220kV main 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:Does the production transformer require 3C certification? Does the country have any specific requirements?
In general, the production of power transformers do not require 3C certification. The state does not have specific requirements, but if you want to tender, is certainly qualified, the most important is: the state authority of the type of test report (often: National Transformer Quality Supervision and Testing Center (Shenyang)) and model registration Certificate, then ISO9001
Q:Transformers 2: Revenge of the Fallen?
The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots believing that peace was possible finds out that Megatron's dead body has been stolen from the US Military by Skorpinox and revives him using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots with reinforcements of their own, may have more to deal with then meets the eye. I'd take that with a pinch of salt though as it's probably fan invented.
Q:incompatible step-up/down transformer and laser printer?
It's not quite clear how your battery charger and step up/down transformer are associated or if you tried to use the step up/down transformer to power the laser. I'm guessing you tried and it didn't work and now your step up/down transformer doesn't work either. Since you've exceeded the power output of the step up/down transformer by using the laser, one of several things may have happened: 1. there is a safety fuse that has been blown in the step up/down transformer 2. there is a built-in circuit breaker that has been tripped in the step up/down transformer 3. you've damaged the circuitry/wiring in the step up/down transformer permanently 4. if the battery charger was plugged in at the same time (theorizing it is a separate device) it may have been damaged by the low power available by the power draw of the laser that the step up/down transformer was trying to supply You should always verify the power requirements of equipment to that of the supply before using them together and remember to calculate for total power of everything that is plugged into the supply that is being used at the same time. It is recommended that laser printers should not be plugged into power strips or surge protectors unless they are specifically designed for that heavy of a power load as most are not. If you haven't already, try removing them all from power for a few minutes or a couple of hours and then try plugging them in one at a time to a standard wall outlet to see how they respond. I would have to see them all to evaluate specifically what was wrong. Best of luck.
Q:jazz from transformers?
Jazz is always voiced by an African American actor, Scatman Crothers, Darius McCrary, Phil Lamaar, but even though Transformers have varying ethnic voice actors, or for some reason, a human foreign accent, they're one race and not considered white or black, or foreign no matter what part of Cybertron they come from. They're either Autobot or Decepticon, and they're allegences, not races. They're Cybertronian by birth, Decepticon is a faction name created by Megatron, and Autobot is the governing force later changed to the title of the good guys amidst the war. I think it's just tradition for Jazz to have a African American voice and sound cool on acount of his name
Q:Who would win in a battle to the finish Voltron or the Transformers?
Q:Three - winding transformer winding problem
But from the operating and manufacturing costs, low - medium - high arrangement, more reasonable. 1, from the operation to consider: step-down transformer, low pressure side is often for the distance of the load. And the voltage level is low, the protection level is lower. So we hope that the low-high impedance is bigger as well. While the pressure is often for the far load, we hope that the impedance between them is smaller as well. This arrangement, just to meet this requirement.
Q:What are the specifications of the transformer capacity?
The choice of transformer capacity has a great impact on the comprehensive investment efficiency. Transformer capacity selected too large, there "big horse car" phenomenon, not only a one-time investment, no-load loss is also large. Transformer capacity selected too small, transformer load loss increases, economically unreasonable, technically not feasible.
Q:What is the vacuum impregnation of the transformer?
In addition, if the conditions can also be limited if the transformer high temperature dipping (100 ~ 120 degrees), you can play the same effect
Q:What is the normal color of the transformer oil?
transformer oil are produced using the appropriate refining process, the color is shallow, generally light yellow, according to GB / T 6540 method to measure the color are below 1, and some oil color close to the water white. Oil in the use of the process, due to oxidation will produce acidic substances or sludge (sediment),
Q:What is the rated current of the 80KVA transformer?
Rated current calculation of transformer Primary side approximation 0.058 * KVA (transformer capacity, size 10kV / 0.4kV) Secondary side approximation 1.44 * KVA (transformer capacity, size 10kV / 0.4kV) Known transformer capacity, and its voltage level side rated current Formula a: Capacity divided by the voltage value, the business by six divided by ten. Description: Applies to any voltage level. Unit KV 80KVA transformer low voltage rated current is: 80 * 1.44 = 115.2A
