Description

The application of the 250MVA/220kV standby transformer power station, 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 250MVA/220kV standby transformer power station. 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 the 250MVA/220kV standby transformer power station, 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 te

Core: The three-phase three-pillar structure inside and outside the box rolling. Center column for the multi-step cross section. After rolling core using vacuum annealing to remove stress, bending clamping groove. Pull screw to tension the body. Core surface brush special angle glue, to ensure core is not deformed and not rust.

Coil and the body: low-voltage coil made up of 1 to 6 wires together to four layers or double-cylinder type (500KVA and below), or spiral-type. High voltage coil axial direction Oil conduit and high-low voltage main oil gap are Stays curtain structure. Iron yoke insulation and trapezoid pads as one, so that the body uniform compression, body structure using the new safety board positioning, vertical and horizontal orientation, ensuring that is no displacement.

Tank: The ripple tank, sealed structure, no leakage, maintenance-free.

Q: i heard a new was coming out ,i hope so ,the first two rocked!!!: Transformers 3 is estimated for a July 1, 2011 release.

Q: Transformer fever how to do?: ?Equivalent aging principle is the transformer in the part of the running time of the winding temperature is lower than 95 ℃ or underload, then in another part of the time can make the winding temperature higher than 95 ℃ or overload, as long as the overload time more than the life of life is equal to Transformers in the under-load time less loss of life, both offset each other, it can still maintain a normal life. ????Transformer insulation aging six degrees principle: ????When the transformer winding insulation temperature in the range of 80 ~ 130 ℃, the temperature rise of 6 ℃, the insulation aging rate will be doubled, that is, the temperature rise of 6 ℃, the insulation life is reduced by 1/2, which is insulation aging "Six Degrees".

Q: Parallel can provide the total capacity is not the sum of the capacity of the two transformers, or how to calculate? What is the principle of allocation of load load, that is, how to allocate two transformer load capacity?: After the parallel capacity can be provided is the sum of the capacity of the two transformers ---- If the two transformers capacity is the same, after the parallel capacity can provide the total capacity of the two transformers are the sum of capacity. If a 1000kva transformer and a 800kva transformer in parallel, the parallel can provide the total capacity of 1600kva. The distribution of load load and what principles, that is, how to allocate two transformer load capacity --- transformer parallel to meet the three conditions: 1, two transformer transformer ratio equal; 2, two impedance voltage equal; 3, two Transformer capacity should be as close as possible, should not exceed 3: 1. To meet these three conditions in parallel, the load is evenly distributed to two transformers.

Q: Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.: unlikely they will not

Q: I went to go see transformers yesterday and one of the previews shows a bunch of people at a party with someone videotaping the party. Then there are explosions in the distance and at the end the head of the statue of liberty lands in the street. They don't say what the name of the movie is but it has a january of 2008 release date. Does anyone know the name of this movie?: Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^

Q: What is the vacuum impregnation of the transformer?: To complete the winding and core assembly of the transformer, into a special dipping tank, the first vacuum, then open the lacquer,

Q: does anyone know what the songs are in transformers???????: 01. Linkin Park - What I've Done 02. Smashing Pumpkins - Doomsday Clock 03. Disturbed - This Moment 04. Goo Goo Dolls - Before It's Too Late (Sam and Mikaela's Theme) 05. The Used - Pretty Handsome Awkward 06. HIM - Passion's Killing Floor 07. Taking Back Sunday - What It Feels Like To Be A Ghost 08.

Q: What is the meaning of the transformer 'turns ratio'? what's the effect?: The number of turns of the primary coil (that is, the number of turns around the coil) and the number of secondary turns. Turns ratio and voltage ratio is proportional. For example, 220 volts to 10 volts voltage ratio is 220: 10, turns ratio should also be 220: 10, such as the primary is 2200 laps, the secondary should be 100 laps. Multi-turn ratio is the number of turns of the secondary output and the primary correspondence. A variety of turns ratio is to allow a sensor device is used for a variety of heat treatment process. I remember answering your question? how? Do not believe? 'U1 / U2 = n1 / n2' "/" Or ":" read here as "than", the size of the ratio is that you say the size of the divisor, you put it when the division can also be seen. U1 / U2 = n1 / n2 'U1 denotes the primary voltage of the transformer, U2 denotes the secondary voltage of the transformer, n1 denotes the number of primary turns of the transformer, that is, the number of turns, n2 denotes the secondary turns of the transformer, The number of turns, n1 / n2 is the turns ratio. The meaning of this formula is: transformer primary and secondary voltage ratio = its primary and secondary turns ratio (turns ratio) I do not know you can not understand, do not understand I can do nothing
