The application of ±800kV (HY14) of UHV converter 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 the 1500MVA/1000kV UHV AC 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 1500MVA/1000k 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:How to use a multimeter to determine the quality of small transformers
Small transformer primary coil is generally 1 ~ 2k ohm, the secondary coil tens of ohms. If the problem with a multimeter measuring coil or open circuit, or open. There is also a fault that there is a short circuit in the middle of the coil, so that you only take the same transformer to compare the coil resistance.
Q:transformers 2?
No there is no trailer yet because there is no footage yet. The film is currently 'in production' and will hit cinemas next year. Look for a teaser soon enough.
Q:10 (6) What is the meaning of 10 and 6 in the KV transformer?
These numbers refer to the voltage, 10 (6) KV transformer 10 and 6 refers to the primary side of the transformer voltage level is 10kV or 6kV. 10 / 0.4 (0.22) KV substation in the number of "/" refers to the transformer primary side of the voltage level 10kV, followed by the transformer secondary side of the voltage level is 0.4kV and 0.22kV, that is, 400V And 220V The primary voltage is the voltage of the transformer line, the secondary voltage is the voltage after the transformer transformer.
Q:Transformers Revenge of the Fallen DS help?
Well, it sort-of has a create a bot feature, but not quite. In the beginning of the game, when you get your transformer as a protoform and once you get to do actual missions, you get to choose out of only three types of vehicles: A light but fast car, an all evened out sports car, or a heavy armoured tank (sort of like another game). However, you can only chose one because you are stuck with that form for the rest of the game. HOWEVER,with energon you pick up fighting other enemies and scanning computers or machines, you can customize stats (attack, agility, defence, ranged attacks, health, and regeneration of health) an customize your robot with different weapons. The game is not a wander-around game like its predecessor, but challenges are available. I guess after you beat the game or when going throughout levels, you play as transformers such as Starscream (beginning of Decepticons) or Optimus Prime (beginning of Autobots).
Q:630KVA transformer can use the maximum number of power appliances
No additional measures in the case, 630KVA transformer can use the maximum 420KW power appliances. 1, the transformer power factor is generally 0.8 (also 0.7), then, the total power transformer = 630 * 0.8 = 504KW. 2, according to the "power engineering design manual", the transformer capacity, for a smooth load of a single transformer, the load rate is generally about 85%, so the upper case, with electrical power = 504 * 85% = 428.4KW. 3, if it is a single high-power motor, starting current as large, even if the measures, but also a corresponding reduction in electricity consumption. 4, if the three-phase imbalance, but also a corresponding reduction in electricity consumption.
Q:Transformer copper row selection
Answer: no love language, all the text is boring.
Q:10 (6) /0.4kv three-phase transformer what does it mean
Therefore, the decision to 60 and 35kV winding connection to be careful when the connection must meet the transmission system voltage phasor requirements. The connection between 60 and 35kV windings is determined according to the relative relationship of the voltage phasors. Otherwise, even if the capacity of the voltage ratio is also right, the transformer can not be used, connected wrong, the transformer can not be connected with the transmission system. 3). Domestic 10,6,3 and 0.4kV transmission and distribution system phase also has two phases. In the Shanghai area, there is a 10kV and 110kV transmission system voltage phase difference of 60 ° electrical angle, this time can be used 110/35 / 10kV voltage ratio and YN, yn0, y10 connection three-phase three-winding power transformer, but limited Three-phase three-core core. 4). But note that: single-phase transformer in the combination of three-phase group connection, can not use YNy0 connected three-phase group. Three-phase shell-type transformer can not use YNy0 connection.
Q:What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master
10KV / 0.4KV, 800KVA Transformer rated current is: High pressure side, I = 800 / (1.732 * 10) = 46.2A Low pressure side, I = 800 / (1.732 * 0.4) = 1154.7A Low side of the economic current is about: 1154.7 * 70% = 808.3A
Q:Electric transformer winding calculation.?
Basically, the ratio of voltages is the same as the ratio of turns. The currents are the inverse ratio but that kind of takes care of itself if you just deal with the voltage ratio.
Q:Why 21 lighting transformers must use double-winding safety isolating transformers,
Double-winding type safety isolation transformer load side and the power supply side is not electrically connected, is safe, and autotransformer primary shared a winding, it has a direct electrical connection with the power supply, unsafe.
