The application of the 380MVA/525kV single-phase double winding generator 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 380MVA/525kV single-phase double winding generator 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 380MVA/525kV single-phase double winding generator 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:Transformers Movie!?
well gee i watch the cartoons as much as i can and well from what i remember, the first few episodes from g1 (1984 series) there were like 15 autobots and 18 decepticons (i don't know exactly). And then in the Armada series if you don't include the dozens of mini-cons seen fighting unicron then i'd say only about 8 known autobots and then 10 known decepticons Tidal Wave Tidal Wave. and i didn't get to see much of energon but i suspect that there were a little more then in armada plus a few mini-cons seen here and there and then the hundreds of terrorcons and smaller number of omnicons (thse are the guys that collect the energon)
Q:how to maintain dry transformer winding?
there is no oil for transformers. they are kept dry by all the heat they generate. it cooks the moisture out. if there is a specific reason you are worried, please do tell. is it going to be stored or go unused for a while? is there a lot of moisture in the area of operation? if not, i would not worry about it. it sounds as if it might be near the end of its life cycle as is. on the bright side transformers dont just burn out. there must be a reason for the failure. moisture is not too bad, but water is.
Q:Old transformers tv show question?!? 10 points for best answer!!!?
Rumble and Laserbeak
Q:Question on transformers?
Assuming 100% efficiency in the transformer: If the razor draws 0.15 amps at 110 volts, current on the 230-volt (primary) side of the transformer would be: 0.15(110/230) 0.072 amperes (72 milli-amperes).
Q:electronics -pls explain about transformers,ICC,etc?
you are able to't be born to be any specific way. not something is thoroughly genetic. there is an environmental impact. Even interior the womb the ambience has an impact which isn't thoroughly because of the genetic of the toddler. the ambience of the womb might desire to be one element that motives people to be lesbian even though it won't be a ingredient in being gay. If homosexuality replaced into thoroughly genetic MZ twins might the two be the two gay or the two at as quickly as. you are able to tell how lots androgens you have been uncovered to prenatally by the ratio between your 2nd and fourth palms on your good hand. Many have been uncovered to androgens who have not grew to become out to be gay. There are cures for toddlers who had too lots androgen exposure. This situation is extra complexed than you think of. I additionally think of that in the event that they have been born that way we'd see warning signs of homosexuality before and homosexuality might nonetheless be considered a ailment.
Q:A liter of transformer oil how much jin
(3) arc suppression effect: In the oil circuit breaker and transformer on-load regulator switch, the contact will produce an arc switch. As the transformer oil thermal conductivity is good, and in the arc under the action of high temperature can touch a lot of gas, resulting in greater pressure, thereby enhancing the dielectric arc performance, so that the arc quickly extinguished.
Q:How long does it take to restart the transformer?
If the transformer is shut down for a month or on hold, the trial is stopped for more than 6 months before the commissioning? A: The transformer shut down for a month, before the resumption of power transmission should be measured insulation resistance, qualified to be put into operation.Post or outage for more than 6 months of the transformer, should be done before the insulation resistance and insulation oil pressure test Dry and cold areas of irrigation and drainage dedicated transformer, the suspension period may be appropriate to extend, but not more than 8 months
Q:Transformer 1250KVA Dimensions
10kV grade distribution transformer oil immersion 1250KVA appearance size 1786X1170X1410 (length X width X height); dry 1250KVA appearance size 1470X1200X1450 (length X width X height), for reference, the specific best asked suppliers.
Q:What is the SN on the transformer? What is the difference between it and the actual power of the transformer?
The unit of apparent power SN is kVA, "Transformer's actual power" is said that active power, right? Active power PN = SN * power factor, in kW
Q:Transformer movie?
transformers is a classic. of course everyone should go see it.
