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:I have halogen lights in my basement. When i mean contact i am talking about this little hanging jack where by you plug in the light bulb into. For some reason, one of my lights are not working properly but I have already tested the light bulbs out. I have a feeling that the contact/transformer (hanging jack slot) is ineffective. Does anybody have an idea how to change these things?: Pull a light from one that you know is working and try that, also if your not using sealed bulbs don't touch the lamp. It depends on the type transformer if that is your problem, turn off the power, remove it and order the replacement part

Q:220V to 12V transformer L N + V + V on behalf of what? The more detailed the better! Thank you prawn: L FireWire N zero line The other two are output positive, and the output is negative

Q:i have read different forums explaining what really is an isolation transformer but unfortunately i am having trouble on grasping the main idea? please help, why do they say that isolation transformer can help a person being electrocuted even if he touches one of the secondary terminals??? how is that??? thank you: how does isolation transformer prevent a person from being electrocuted when touched the secondary? There are two common ways to get electrocuted by line powered equipment. Using an isolation transformer eliminates one of those ways. To get electrocuted electric current has to flow across your body, typically your heart. If you connect each of your hands to the output leads of an isolation transformer, you still get electrocuted. But there is another way to get electrocuted using line powered equipment. One side of the electric outlet is tied to earth ground, so if you touch something connected to the hot side of the wiring and have something else (like your other hand) connected to something that is grounded (like plumbing or a grounded appliance) you get electrocuted. The output of an isolation transformer floats the output in relation to earth ground, so if you touch some part of the transformer's output very little current will flow through you even if you are standing in water. You may wonder why I said very little current instead of zero current. The reason is that we live in an imperfect world where the insulation in the transformer may not be perfect and your body has a tiny bit of capacitance. For most purposes this doesn't matter but if you are dealing with medical equipment with electrodes attached near the heart, this sort of thing has to be addressed. A GFI outlet works in a somewhat related way. It compares the electric current in the hot and neutral lines in the socket. If these currents don't match, the assumption is that something is shorting the hot side to ground (maybe through you!) and cuts the power.

Q:assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain: In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.

Q:I enjoyed both of these titles' first games very much. I am a big Transformers fan but I also love the first person shooting action Borderlands has to offer. I only have enough money to pre-order one and get it on its release date but I can't decide. What are your opinions? What will I get better gameplay value out of? Which do you think has a better pre-order bonus? I welcome any and all opinions and answers!: Hi, okorder

Q:I will be living in Germany for a while and I'm trying to plug my TV in, as well as one or two other things. The 1000 transformer I have works, but whenever I plug in the power strip to plug in more things than just the tv, it will automatically blow the power in the house and I have to go flip the switch again. Other Americans I know here in Germany do not have this same problem. I need help!: Only if the power strip is also rated at 3000 volts or higher. Otherwise, definitely not.

Q:around the house. Im looking for a step up transformer to handle 1.5VAC-18VAC with a ratio of 1:10 or 1:20. Which household objects would contain this??: well if you use a step down transformer in reverse, it might work. most power blocks will have it, the big heavy cube things you plug into a wall then into some device. a 12 volt power supply should in theory have a 10:1 step down take that in reverse and you'll have 1:10 step up 6-12 volt output block transformer is what you should look for (assuming your wall power is 115-120 AC).

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:i would say transformers alll the way: Harry Potter

Q:how to calculate the secondary current of the transformer for example 1200 amps in primary ,primary voltage is 220kv and the secondary voltage is 34.5 kv of the transformer .: For an ideal transformer, the voltage ratio is set by the turns ratio, so the transformer is a stepdown with the ratio of 220/34.5. The current ratio is also set by the turns ratio, but current goes up as voltage goes down, so the secondary voltage is 1200 x (220/34.5). Again, for an ideal transformer only.
