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 transformers belong to special transformers: Transformers are generally used for AC voltage conversion if used for other purposes such as changing the frequency of the power supply, rectifying the power supply of the equipment, the power supply of the welding equipment, the electric power of the furnace or the voltage transformer, the current transformer.

Q: A transformer rises the voltage in proportion of 1 to 10. If the power in the primary coil is 100 watts, we should expect a power of ____ watts in the secondary coil. a) 10b) 100c) 1,000: Transformers can step up voltage, but in doing so, they step 'down' the current. Ideally, the voltage will rise by the same proportion as the current will fall. And since power is PVI, the power will remain unchanged. So the answer is that the power in the secondary should be the same as the power in the primary, which is 100W.

Q: Any help much appreciated here, I cannot understand the following formulas at all. If there is anyone who can please explain in very SIMPLE words I would be very grateful. My exam is next week and I am still stumped on the following.VP/VS NP/NS IS/IP ok this bit I understand, but then here are the QAs that don't make sense to me:Q1) A single phase transformer has 1250 primary turns and 200 secondary turns. Primary V I are 230V and 3A. What are the secondary V I?A) 1250/200 230/vs transpose too: VS 200 X 230/1250 36.8V Why has it been turned upside down?230/36.8 Is/3transpose too: Is 3 X 230/36.8 18.75A Why??The following Q I am even more stuck withQ2) Single phase transformer has a rating of 300/230V, 15KVA. What is the full load of primary and secondary?A)S VI Where did S come from?!Ip 1500/3300 4.55A KVA - is this taken as the V? Not I? Is that why Is 1500/230 65.22A it has been reversed? I'm very confused, please can someone help explain this process to me?: Transformer Formulas

Q: How long does it take to restart the transformer?: What are the requirements for the commissioning and outage of the transformer? A: (1) the new operation of the transformer must be rated voltage under the impact test 5 times, overhaul after the impact test 3 times. (2) the transformer put into operation when the first cooler, cooler running for a period (about 15min) time, until the oil temperature is no longer rise and then stop. Disconnect the transformer first. (3) 110kV and above in the neutral point direct grounding system, put into operation and outage transformer, the operation must be grounded before the neutral point, after the operation and then decide whether to decide whether to disconnect. Transformer neutral point access to the arc suppression coil should be first after the exit. The neutral point of the two transformers should not be connected to a neutral bus with an arc suppression coil.

Q: I Watch Transformers,But Alot Of People Seem To Hate It.: they are robots in disguise It seems sneaky why are they hiding? also the animationsucks it was from the era of crappy animation and based on selling toys after warner brothers and before ren stimpy and recent computer done stuff.

Q: Sichuan transformer manufacturer that a best?: Sichuan Meishan New Transformer Co., Ltd.'s products have the strongest load capacity, up to 200%

Q: i wish to construct a transformer with 220/120v,60hz,5watt,plz help me: Transformer is a thing which can reduce or increase voltage. In your question, You want to make such a transformer which can reduce the voltage is called a step down transformer. In transformer there are two coils. One is Primary and the rest of them is Second nary coil. Primary Coil is connected with input(220v) and Second nary with output(120v).To get 120v in output the transformation ratio should be 220:120 means 11:6.

Q: I bought a Neon Sign Transformer over OKorder and for a while it worked great. I used it to power a Jacobs Ladder (I wired the transformer straight to the Jacobs ladder). However, now the transformer will turn on the jacobs ladder but after a couple of seconds it will shut off and sometimes make a buzzing noise. What is wrong with it and how can I fix it?: You have 2 problems there. 1. Voltage; 2. Frequency. In this case, both are against you. NZ has 50Hz mains frequency at 240V. If you are really lucky, the transformer will have dual windings on the primary, or a 220/240V. tap. If you don't know what you are doing, consult an electrician or electronics tech. to have them check whether it is dual voltage, and change it. The frequency difference can mean a little less efficiency, the transformer may get a little warmer in operation. But it should be fine. You only other options are to replace the transformer (get one for dual voltages?), or use a 240/110V stepdown transformer ahead of it. The stepdown transformer must have a sufficient power rating for the job.

Q: Transformer is the transmission of electrical equipment: Transformer is the power of the transmission of electrical equipment, it is the primary energy transformer through the electromagnetic coupling, to the secondary side, we need to become the voltage and current, the frequency does not change the power supply.

Q: Hey I was just wondering if the Nintendo DS version of the Transformers:Revenge of The Fallen game still had the Create-A-bot feature where you can customize your own transformer or if you had to play as the movie characters?: 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).
