 Description

 

The application of the 360MVA/242kV three phase water cooling main transformer for  hydro power station.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/242kV three phase water cooling main transformer for  hydro power station. 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 the360MVA/242kV three phase water cooling main transformer for  hydro 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q:Which Autobots and Decepticons r going to be in Transformer-2?? Any ideas?
Soundwave. Optimus Prime 3
Q:TransFormers Or Spider-Man 3 the best summer movie?
I'll have to say Transformers. Here's a comparison: The Storyline: SPIDER-MAN 3 Peter starts to enjoy being a hero, to the point of risking the people he loves (including his fiancee MJ) just to satisfy his ego and wants. In the end, he almost lost MJ (again, as with the first 2 films) and reunited with his best friend (who died anyway). TRANSFORMERS A group of robots called Decepticons are looking for the AllSpark, a device from their planet Cybertron that can turn objects into robots as well. Luckily, Autobots led by Optimus Prime are here on Earth to save the day. Winner: SPIDER-MAN 3 Action Scenes to watch out for: SPIDER-MAN 3 Sandman's attack on the city, and the final battle between Spidey and Venom (with the steel bars) TRANSFORMERS The first Decepticon attack on a military base, the scorpion-like Decepticon attacking a Middle East country, and the chase scene between the yellow Camaro and the police car. Winner: TRANSFORMERS The actors: SPIDER-MAN 3 Tobey Maguire looks silly as a hero gone bad. Thomas Haden Church was under-utilized. And Kirsten Dunst's performance was lazy. TRANSFORMERS Shia LaBeouf! Megan Fox the bombshell! Shia LaBeouf! This lead actor carried this movie throughout the end, with his charm and humor. Winner: TRANSFORMERS
Q:Searching for robot/transformer party food ideas?

Q:design a quarter wave transformer to match a 73 ohms antenna to 300 ohms transmission line fed by a 100MHz FM?
Transformer impedance required: sqrt (73 x 300) 147.986 (say 148) ohms. The 1/4 wavelength in air is (75/100) 0.75 metres. You have not stated what you are using for the transformer, so you will need to allow for its velocity factor. But the transformer could be 0.75 metres of parallel rod spaced as required for the impedance. I am also assuming the antenna is balanced (sounds like a folded dipole).
Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
There are two ways to adjust the tap in the transformer. 1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
Q:Why does the transformer have three lines
There are three lines is normal, because in addition to a line of fire a zero line, there is a ground wire (ground wire is directly connected to the Earth's line, it can be called a safe circuit, dangerous when it put high pressure directly To the earth, be a lifeline. Transformer is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: power transformers and special transformers.
Q:Tube power transformer help?
Get get right of entry to to an impedence meter and degree what the transformer relatively is (impedience clever). you will discover small transformers with an identical turns ratio and not additionally be near to what you like. If there's a marking on the transformer , you're waiting to seem it up. the different element is that utilising tubes at very low voltages would positioned you into very non linear tiers of operation. the entire thought of utilising a triode or a tetrode amp is for a tube sound and to get low distortion or controled distortion. beginning at 5 to ten% distortion isn't great. i assume you're speaking approximately utilising something like a 3V4 or in all possibility between the tubes designed for listening to aids. Neither replace into designed for finished constancy. Microphonics are a controversy. there are a number of integrated amplifiers that are very low distortion and could no longer require an output transformer.
Q:Transformer parameter interpretation
C, rated current (A): transformer in the rated capacity, allowing long-term through the current. D, no load loss (kW): when the rated frequency of the rated voltage applied to the end of a winding, the other winding open when the active power. And the core silicon steel sheet performance and manufacturing process, and the applied voltage. E, no-load current (%): When the transformer in the rated voltage under the secondary side of the load, the current through a winding, generally expressed as a percentage of the rated current. F, load loss (kW): the transformer secondary winding short circuit, in a winding rated tap position into the rated current, then the power consumption of the transformer. G, the impedance voltage (%): the secondary winding of the transformer short circuit, in a winding slowly increase the voltage, when the secondary winding short-circuit current equal to the rated value, then the voltage applied once the general. As a percentage. H, the number of phases and frequency: three-phase beginning to S said, single-phase start with D said. China's national standard frequency f is 50Hz. Foreign countries have 60Hz (such as the United States).
Q:Microwave transformer wires?
transformers is a movie, silly. your microwave is not an autobot, dont worry
Q:My device has 50KW should be used with much transformer
Equipment is 50KW? That is to say there are other electrical appliances, you put all the power are considered, a total of how much KW, must start the current is 16 times the original current ah.
