 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:Where do I get an audio output transformer without buying it. Is there some kind of toys or electronics which?
no. there is no such thing as a generic output transformer, each is sized according to power handling and specific tube/transistor characteristics. some even have additional windings to facilitate inverse feedback, gain leveling, or similar circuits. historically, tube power amps were designed according to the transformer selected because that affects many design parameters. considering the pervasiveness of transistor amp designs that do not use an output transformer, you would be hard pressed to find one in most toys or other electronics.
Q:10 (6) /0.4kv three-phase transformer what does it mean
Three-phase five-column core transformer must be used YN, yn0, yn0 connection, in the transformer must be connected into the angular connection of the fourth winding, it is not out of the beginning (the structure to do the electrical test when the lead is not This case). 5). When the transformer of different connection group is running in parallel, the general rule is that the connection group label must be the same. 6). When the distribution transformer is used in the multi-mine area, the Yzn11 connection method can be used. When the z-connection method is adopted, the impedance voltage algorithm is different from the Yyn0 connection method, and the copper consumption of the z-way winding is more. Yzn11 connection distribution transformer lightning protection performance is better. 7). Three-phase transformer with four volumes when the core frame can not be used YNy0 connection. 8). These are used for the domestic transformer connection, such as the export should be required to supply the appropriate connection and connection group label. 9). Generally in the high-voltage winding are connected with the tap-changer. Therefore, when selecting the on-load tap-changer (including the on-load tap-changer and the off-circuit tap-changer), it must be noted that the transformer connection and the on-load tap-changer (including connection, test voltage, rated current, Level voltage, voltage range, etc.). YN connected to the on-load tap-changer used on-load tap-changer, it is also important to note that the midpoint must be able to lead.  The answer is recommended by the questioner
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:My nearly three year old son is obsessed with Transformers?
Must his favorite cartoon thats just like my 5 year old nephew he is obsessed with Sponge Bob Square pants
Q:Transformers of the three transformations are the three?
Take a 10kV / 0.4kV, d / yn11, 100kVA transformer rated voltage full load operation: 1, the high side of the 10kV into the low side of the 400V; 2, the high pressure of 5.77A into low pressure side of 144.4A;
Q:Why do people use transformers?

Q:Transformer winding maximum temperature at?
National standard "dry-type transformers" GB6450-1986 on the dry-type transformer temperature limit to make the provisions. 1, the dry-type transformer coil, when the use of A-class insulation material, the ultimate operating temperature of 105 ℃, the maximum temperature rise should be less than 60 ℃; when the use of E-class insulation material, the limit operating temperature at 120 ℃ , The maximum temperature rise should be less than 75 ℃; when using B-class insulation material, the extreme working temperature at 130 ℃, the maximum temperature rise should be less than 80 ℃; when using F-class insulation material, the limit operating temperature at 155 ℃ , The maximum temperature rise should be less than 100 ℃; when the use of H-class insulation material, the limit operating temperature at 180 ℃, the maximum temperature rise should be less than 125 ℃; when using C-class insulation material, the extreme working temperature at 220 ℃ , The maximum temperature rise should be less than 150 ℃.
Q:Physics? transformer help?
In electricity, a transformer is like a simple machine. It is a device used to turn large amounts of voltage with low current into small amounts of voltage with high current or vice verse. The power (IV) remains the same, but you can raise and lower voltages as necessary.
Q:How to increase the transformer output current
If the transformer is not in the case of overload, then increase the load, multi-access electrical equipment, it increases the output current. Otherwise it is not safe. If you do not change the structure of the transformer, do not change its specified cooling method (such as air-cooled, water-cooled), does not change its specified ambient temperature, then its rated current can not be changed.
Q:Why does the transformer have three lines
You see how it is connected to the law ah ~ which is connected to the power supply is the power cord ah ~ may also be the designer in order to be able to work at 220 and 110 (some countries are 110) and designed. Why did he do so?
