Description

The application of the 50MVA/220KV SF6 Bushing startup/standby transformer, and matches well with the transmission capacity of UHV 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 50MVA/220KV SF6 Bushing startup/standby transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV 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 UHV 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 UHV 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 UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 50MVA/220KV SF6 Bushing 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 UHV Transformer products.

Q: I am working on a lengthy project and have one little area that I am not sure how to answer. I need to know how to size a transformer for a building. Does anybody know the equation or method for doing this? The service coming in is 480Y/277V and the step-down is to a 240/120 single phase panel. Any help is great! Thanks: Are you talking about sizing the 'dry-pack' step down from the 480V 3 phase to the 240 volt 1 phase? Or the overall service transformer? The overall transformer must carry all the loads of the building. The 'fudge factor' given by a previous answerer doesn't take into account enough details. If the transformer is located in a vault inside the building, it must be de-rated because it will not get as much cooling from airflow as it would outside. Do heating loads or cooling loads dominate? Cooling loads call for further de-rating as the load will be at maximum when the temperature is at maximum. Heating loads are better as they peak when temperatures are lowest, helping cool the transformer windings. Check with the local utility company. Load growth? You want to have capacity for the loads to grow without having to upgrade the transformer. If you're sizing the step down, you need to know the loads it will be serving plus the efficiency of the dry pack transformer itself (typically fairly low) as that will be part of the load placed on the main transformer. kVA is an acronym for kilovolt-amperes, roughly analogous to kW - kilowatts. If you have 10,000 watts of equipment connected, that's 10 kW or approximately 10 kVA, but you would still need to make all the necessary adjustments above to properly size the transformer. Check with an electrician or the buildings electrical engineer, failure is definately an option, but won't make anyone happy. It's as much art as science and varies greatly on information not given here.

Q: I need to get a transformer that produces 12 watts. Problem is that I burned out the previous 2 I had with my hot wire cutter. I have a couple of 9 watt and 3 watt transformers. Is there anyway I can combine them together so that I can produce the desired 12 watts. I was thinking about rectifying to DC. Then putting the power sources in parallel to power my hot wire cutter. Is this a good idea or is there another way to do it.: no, connecting two transformers together, unless they are identical, doesn't work. The one with the higher voltage will see the others as low impedances and try to drive them, with the result of a burned out transformer. But if you rectify each one to DC, the diodes will prevent the lower voltage ones from overloading the higher voltage one, but you will still have a problem in that the higher voltage one will be the only one delivering any power. .

Q: Why is the transformer coil insulation?: Because the transformer is used in different environments, according to different insulation level selection, can extend the life of the transformer. Transformer (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 purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q: I just saw the movie and it has left me with a thirst for more on the story of transformersbut where can I turnComics, animated series?Thanks: Get the animated series. They totally rock!

Q: Before engaging any technician i want to gather some knowledge about planer transformer. It will be good if u have any suggestions.: While operating under the same laws of physics and using the same materials (i.e. copper, ferrites) like the conventional transformers, these Planetics? planar transformers have different construction geometry that reflects handful of technological advantages.

Q: I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?: SQUEEK? That sounds like a high (audio) frequency oscillator. So this sounds like a pulsed regulator, not like a transformer-type power supply. I would guess that your unit is measuring the battery voltage, then applying a pulse of power to charge the battery, then checking the voltage again in a continuous sequence. This would be a switching type charger. 5 Volts - sounds like a personal electronics unit, for instance a cell phone or personal entertainment. Right? 240 Volts - Sounds like Europe. Right? (In America it would either be 120 Volts or some switching supplies are designed to operate from 90 to 250 Volts.)

Q: I'm 13 and I love the Transformers movie, TF Animated and TF Armadaactually, those are the only ones I HAVE seen so farI'm just wondering where to start with attempting to watch them all? And in what order? Or, doesn't it matter? I suppose it does with G1 and 2Where on the internet can I watch them? Any recommendations?Please answer! I really want to have seen every one!: not okorder

Q: I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you: NO IT WILL NOT SHORT THE XFORMERCONNECT X2 TO GROUND. PREFERABLE AN EARTH GROUND, BUT AT LEAST THE ELECTRICAL GROUND.

Q: i have a bunch of transformers and they have the dates like i have optimus prime it says takara hasbro 1980-1982 and all the other toys say hasbro or takara! and most are made from 1982 -1985 also i have jet fire but the stamp doesn't say hasbro or takara but it does say bandai 1984!: i'll answer throughly. bandai is a japanese brand which produce toys. but you asked how do i tell if my transformers are G1 or real. you can tell by its looks. g1 models looks like a box (quite square in shape), but the latest 1 looks modern.

Q: i have this audio transformer (about the size of a bottle cap) with three prongs on one side and two on the other. i am completely mystified by this configuration. how would i (say for example) hook up this transformer to a 9v battery in order to increase voltage? thx: There is no reason why the higher output supply would draw more current. The input current to the supply is indeed proportional to the amount of power consumed on the other end. In addition, it is even possible that the new power supply might be more efficient, and use less power if you get a good one. Look for one that has a Green certification. One power supply can be more efficient than the other. No power supply is 100% efficient. For instance, if your PC needs 90 watts and your Power supply is 90% efficient, the supply will need to draw 100 watts from the AC mains. In any case, I don't think you will be using any more energy with the upgraded supply, perhaps even less, and your PC should even run cooler.
