Description

The application of the 40MVA/110KV generator startup/standby transformer, 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/110KV generator startup/standby transformer. 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 OLTC 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 OLTCTransformer’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 40MVA/110KV generator startup/standby transformer, 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 terms of OLTC Transformer products.

Q:i have plenty of 3 phase 220 in my shop, but one of my machines requires 440 3 phase. i was going to use a 75 kva transformer with 440 primary 220 secondary in reverse to supply the machine. it is a 15 hp motor 40 amps. i figured my minimum kva requirment to be 37.5 but more cant hurt for the potential high cutting rates i may need to achieve. i simply wanted to buy the transformer, hook the 220 3 phase supply to the primary, and the output to my machine. I think this will provide me with 440 output. the motor plate says 7-1/2 hp/15- hp. 40/20 amps. Any help is welcome, i hate to buy the transformer and not have this unit work. i would change the motor wiring, but the diagram is gone, and the wires are not numbered, also i believe id have to change all the heaters, which are hard to come by, as well as various other parts in the panel. just seems the transformer is the easiest way to get this machine up and going in prouction.: The only real problem you have to worry about is the capacity of the primary winding to supply enough current for your needs without burning up. That information should be on the transformer. Otherwise, transformers work both ways!

Q:how are opyimy and megatron ( or w/e the f their names are)bros and hoes if they cant have roboet sex!!! if so wheres their mother and is the creator sexist about girls there is no girl robots and for that matter has some1 made a transformers porn yet.: Females - Arcee, Nightbird, etc (and that is just from the 80s) Porn - Yes, see Rule 34

Q:i rememeber when i was a lil kid i used to watch Beast Wars on friday nights. I think it was back in 2000 or so. It was pretty cool too; as opposed to transforming cars, etc, there were transforming animals. also there werent any humans.imo the new transformers animation sucks, though the movie was greatim sure Beast Wars and Transformers are related because they used names like Megatron and Octomus Prime (sp?)so yeah. what happened to Beast Wars?: What rely isn't what occurs on the tip of the day, this is what occurs on the tip of the universe. Scientists say the universe will fall down right into a chain of black holes, and because time does not transpire interior black holes, that could be the tip of the universe. yet another time, the Bible is shown by technology. Does that sound rather like, oh, i don't comprehend, HELL!?

Q:i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad: wrap urself in tin-foil. lol

Q:100kVA above the transformer grounding resistance is how much: National specifications for electrical equipment grounding resistance requirements: 4.1.1 parallel operation of the transformer and other power equipment capacity of not more than 100 kVA, the grounding resistance should not exceed 10 Europe.

Q:does anyone know how big the transformers are in the movie or have an online reference?: There supposed to be about 2-3 stories tall but in the old TV shows they were taller.

Q:What is the use of the lower part of the transformer made of rail?: Transformer parts are equipped with a roller. You can easily pull the transformer into or out of the transformer room. After the transformer is positioned, do not weld the wheels and rails. Another support also received.

Q:SGB10 transformer and SC (B) 10 transformer What is the difference between the two series where the difference, specifically to the 10 type and where the hope that the knowledge of a detailed explanation Thank you: Both transformers are dry transformers. 1, SG (B) 10 is an open dry change, he used the United States DUPONT company's NOMEX insulation paper insulation (high voltage coil, you can see is white, if it is darker that is covered with glass wire The former is American technology, the latter is German technology.) The low voltage coil is a copper foil (there is a B in the model that is made of copper foil). The same is true of B in the SC (B). High and low coils are insulated with VPI (vacuum pressure dipping). The surface of a layer of epoxy resin insulation paint wrapped up. 2, SC (B) 10 model means that the epoxy resin pouring dry change (low pressure is copper foil). The high voltage coil is sealed with an epoxy resin, but the low pressure coil epoxy is hard to pour in, but at the end of the coil is sealed with an epoxy resin. 3,10 is the design serial number, representing the loss standard value. 4, there is a dry change, model SCR (B) 10, he is non-epoxy resin casting package. All with NOMEX paper plus silicone encapsulation is the French technology. This product yield less, better quality. Maybe the price will be higher. You can also look at it. 5, is currently in the country is the three kinds of technology transformers. Epoxy resin pouring products are mostly "F" class insulation level, a few also have "H". SG (B) 10 majority is "H" level. , A few are "C" level. SCR (B) 10 is "H" level. If you still want to know what, you can give me a message.

Q:A 2300/230 V step down transformer is rated at 70 kVA and 60 Hz. Its windings have the following resistances and inductances : Rp 0.093 ohms, Xp0.280 ohms, Rs 0.00093 ohms and Xs 0.00280 ohms. The transformer's rated current at the secondary is 3261 A. Assume that a10 from 2300/230 V and calculate the no load voltage for unity 0.7 lagging and 0.7 leading power factor.: You question does not make sense. First issue: You want to calculate the no load voltage? At the secondary? But you specify a power factor? The only possible interpretation that can be drawn from a specification of power factor is that the transformer is under load. Second issue: You specific primary and secondary winding resistance and inductance. The problem is to calculate open circuit (no load) secondary voltage. But the specification says nothing about the core. If the transformer is open circuited, there is no secondary current, and therefore no voltage drop in the secondary winding resistance and reactance. And the specification says nothing about the core, the one must presume that there is no core loss. In the absence of core loss, and at no load, then there is no primary current, and therefore no voltage drop in the primary winding resistance and reactance. Third issue: what do you mean by a 10?

Q:A step-up transformer is connected to a generator that is delivering 131 V and 96 A. The ratio of the turns on the secondary to the turns on the primary is 859 to 1. What voltage is across the secondary? An-swer in units of kV.What current flows in the secondary? Answer in units of mA.: a step up transformer is connected to the generator. therefore the voltage on the primary side of the transformer is 131 volts. secondary turns/primary turns secondary voltage/primary voltage. therefore voltage on secondary side 131*859 112.529KV secondary turns/primary turns primary current/secondary current therefore current on the secondary side 96/859 111.756mA. in order to cross verify, the power on primary side power on the secondary side. i.e 131*96112.529KV*111.756mA.
